Implementing Authentication in a Nuxt.js App

In this tutorial, I’ll be showing you to implement authentication in Nuxt.js app using the Auth module. For the purpose of this tutorial we’ll be using JWT for authentication.

What we’ll be building

Below is a quick demo of what we’ll be building in this tutorial.

Spinning up a quick API

To save ourselves some time, we’ll clone an API, which I have put together for this tutorial:

$ git clone https://github.com/ammezie/jwt-auth-api.git

Then we install the API dependencies:

$ cd jwt-auth-api
$ npm install

Next, rename .env.example to .env and generate an APP_KEY:

// with the adonis CLI
$ adonis key:generate

// without the adonis CLI
$ node ace key:generate

Once that’s done, let’s run the migrations:

// with the adonis CLI
$ adonis migration:run

// without the adonis CLI
$ node ace migration:run

Before we move on to building the Nuxt.js app, let’s quickly go over the API. The API is built using AdonisJs and it uses JWT (JSON Web Tokens) for authentication. It also uses SQLite.

The API has three endpoints:

  • What we’ll be building
  • Spinning up a quick API
  • Creating a Nuxt.js app
  • Installing necessary Nuxt.js modules
  • Creating a Navbar component
  • User registration
  • Showing whether a user is logged in or not
  • User log in
  • Displaying the user profile
  • Logging user out
  • Restricting the profile page to only logged in users
  • Creating a guest middleware
  • Conclusion

The API also already has CORS enabled.

Now, we can start the API:

$ npm start

We should be able to access the API on [http://127.0.0.1:3333/api](http://127.0.0.1:3333/api "http://127.0.0.1:3333/api"). We’ll leave it running.

Note: Though I’ll be using an API built with AdonisJs for the purpose of this tutorial, you are free to use whatever framework that work best for you.## Creating a Nuxt.js app

For this, we’ll make use of the Vue CLI, so you need to first install the Vue CLI in case you don’t have it installed already:

$ npm install -g vue-cli

Then we can create a Nuxt.js app:

$ vue init nuxt/starter nuxt-auth

Next, we need to install the dependencies:

$ cd nuxt-auth
$ npm install

We can launch the app:

$ npm run dev

The app should be running on [http://localhost:3000](http://localhost:3000 "http://localhost:3000").

Installing necessary Nuxt.js modules

Now, let’s install the Nuxt.js modules that we’ll be needing for our app. We’ll be using the Nuxt Auth module and the Nuxt Axios module, since auth module makes use of Axios internally:

$ npm install @nuxtjs/auth @nuxtjs/axios --save

Once that’s done, add the code below to nuxt.config.js:

// nuxt.config.js

modules: [
  '@nuxtjs/axios',
  '@nuxtjs/auth'
],

Next, we need to set up the modules. Paste the code below into nuxt.config.js

// nuxt.config.js

axios: {
  baseURL: 'http://127.0.0.1:3333/api'
},

auth: {
  strategies: {
    local: {
      endpoints: {
        login: { url: 'login', method: 'post', propertyName: 'data.token' },
        user: { url: 'me', method: 'get', propertyName: 'data' },
        logout: false
      }
    }
  }
}

Here, we set the base URL (which is that of our API from earlier on) that Axios will use when making requests. Then we define the authentication endpoints for the local strategy corresponding to those on our API. On successful authentication, the token will be available in the response as a token object inside a data object, hence why we set propertyName to data.token. Similarly, the response from the /me endpoint will be inside a data object. Lastly, we set logout to false since our API doesn’t have an endpoint for logout. We’ll just remove the token from localstorage when a user logs out.

Creating a Navbar component

To style our app, we’ll be making use of Bulma. Open nuxt.config.js and paste the code below within the link object that is inside the head object:

// nuxt.config.js

{
    rel: 'stylesheet', href: 'https://cdnjs.cloudflare.com/ajax/libs/bulma/0.7.1/css/bulma.min.css' 
}

Now, let’s create the Navbar component. Rename AppLogo.vue inside the components directory to Navbar.vue and replace it content with the following:

// components/Navbar.vue

<template>
  <nav class="navbar is-light">
    <div class="container">
      <div class="navbar-brand">
        <nuxt-link class="navbar-item" to="/">Nuxt Auth</nuxt-link>
        <button class="button navbar-burger">
          <span></span>
          <span></span>
          <span></span>
        </button>
      </div>
      <div class="navbar-menu">
        <div class="navbar-end">
          <div class="navbar-item has-dropdown is-hoverable">
            <a class="navbar-link">
              My Account
            </a>
            <div class="navbar-dropdown">
              <nuxt-link class="navbar-item" to="/profile">My Profile</nuxt-link>
              <hr class="navbar-divider">
              <a class="navbar-item">Logout</a>
            </div>
          </div>
          <nuxt-link class="navbar-item" to="/register">Register</nuxt-link>
          <nuxt-link class="navbar-item" to="/login">Log In</nuxt-link>
        </div>
      </div>
    </div>
  </nav>
</template>

The Navbar component contains links to login or register, links to view profile or logout.

Next, let’s update the default layout to make use of the Navbar component. Open layouts/default.vue and replace it content with the following:

// layouts/default.vue

<template>
  <div>
    <Navbar/>
    <nuxt/>
  </div>
</template>

<script>
import Navbar from '~/components/Navbar'

export default {
  components: {
    Navbar
  }
}
</script>

Also, let’s update the homepage. Open pages/index.vue and replace it content with the following:

// pages/index.vue

<template>
  <section class="section">
    <div class="container">
      <h1 class="title">Nuxt Auth</h1>
    </div>
  </section>
</template>

Our app should now look something similar to below:

User registration

Inside the pages directory, create a new register.vue file and paste the code below in it:

// pages/register.vue

<template>
  <section class="section">
    <div class="container">
      <div class="columns">
        <div class="column is-4 is-offset-4">
          <h2 class="title has-text-centered">Register!</h2>

          <Notification :message="error" v-if="error"/>

          <form method="post" @submit.prevent="register">
            <div class="field">
              <label class="label">Username</label>
              <div class="control">
                <input
                  type="text"
                  class="input"
                  name="username"
                  v-model="username"
                  required
                >
              </div>
            </div>
            <div class="field">
              <label class="label">Email</label>
              <div class="control">
                <input
                  type="email"
                  class="input"
                  name="email"
                  v-model="email"
                  required
                >
              </div>
            </div>
            <div class="field">
              <label class="label">Password</label>
              <div class="control">
                <input
                  type="password"
                  class="input"
                  name="password"
                  v-model="password"
                  required
                >
              </div>
            </div>
            <div class="control">
              <button type="submit" class="button is-dark is-fullwidth">Register</button>
            </div>
          </form>

          <div class="has-text-centered" style="margin-top: 20px">
            Already got an account? <nuxt-link to="/login">Login</nuxt-link>
          </div>
        </div>
      </div>
    </div>
  </section>
</template>

<script>
import Notification from '~/components/Notification'

export default {
  components: {
    Notification,
  },

  data() {
    return {
      username: '',
      email: '',
      password: '',
      error: null
    }
  },

  methods: {
    async register() {
      try {
        await this.$axios.post('register', {
          username: this.username,
          email: this.email,
          password: this.password
        })

        await this.$auth.loginWith('local', {
          data: {
            email: this.email,
            password: this.password
          },
        })

        this.$router.push('/')
      } catch (e) {
        this.error = e.response.data.message
      }
    }
  }
}
</script>

This contains a form with three fields: username, email and password. Each field is bind to a corresponding data on the component. When the form is submitted, a register method will be called. Using the Axios module, we make a post request to the /register endpoint, passing along the user data. If the registration was successful, we make use of the Auth module’s loginWith(), using the local strategy and passing the user data to log the user in. Then we redirect the user to the homepage. If there is an error during the registration, we set the error data as the error message gotten from the API response.

If there is an error, the error message is displayed by a Notification component, which we’ll create shortly.

Before we test the user registration out, let’s create the Notification component. Create a new Notification.vue file inside components and paste the code below in it:

// components/Notification.vue

<template>
  <div class="notification is-danger">
    {{ message }}
  </div>
</template>

<script>
export default {
  name: 'Notification',
  props: ['message']
}
</script>

The Notification component accepts a message props, which is the error message.

Now, we can test out user registration:

Showing whether a user is logged in or not

Upon successful registration, we should be logged in but there is no way for us to know whether we are logged in or not for now. So let’s fix that by updating the Navbar component and adding some computed properties.

Before we do just that, let’s first activate the Vuex store by creating an index.js file inside the store directory. The Auth module stores user authentication status as well as user details inside Vuex state in an auth object. So we can check if a user is logged in or not with this.$store.state.auth.loggedIn, which will either return true or false. Similarly, we can get a user details with this.$store.state.auth.user, which will be null if no user is logged in.

Note: Though I’ll be using an API built with AdonisJs for the purpose of this tutorial, you are free to use whatever framework that work best for you.
Since we might want to use the computed properties in multiple places in our app, let’s create store getters. Paste the code below into store/index.js:

// store/index.js

export const getters = {
  isAuthenticated(state) {
    return state.auth.loggedIn
  },

  loggedInUser(state) {
    return state.auth.user
  }
}

Here, we create two getters. The first one (isAuthenticated) will return the authentication status of a user and the second (loggedInUser) will return the details or the logged in user.

Next, let’s update the Navbar component to make use of the getters. Replace the content of components/Navbar.vue with the following:

// components/Navbar.vue

<template>
  <nav class="navbar is-light">
    <div class="container">
      <div class="navbar-brand">
        <nuxt-link class="navbar-item" to="/">Nuxt Auth</nuxt-link>
        <button class="button navbar-burger">
          <span></span>
          <span></span>
          <span></span>
        </button>
      </div>
      <div class="navbar-menu">
        <div class="navbar-end">
          <div class="navbar-item has-dropdown is-hoverable" v-if="isAuthenticated">
            <a class="navbar-link">
              {{ loggedInUser.username }}
            </a>
            <div class="navbar-dropdown">
              <nuxt-link class="navbar-item" to="/profile">My Profile</nuxt-link>
              <hr class="navbar-divider">
              <a class="navbar-item">Logout</a>
            </div>
          </div>
          <template v-else>
            <nuxt-link class="navbar-item" to="/register">Register</nuxt-link>
            <nuxt-link class="navbar-item" to="/login">Log In</nuxt-link>
          </template>
        </div>
      </div>
    </div>
  </nav>
</template>

<script>
import { mapGetters } from 'vuex'

export default {
  computed: {
    ...mapGetters(['isAuthenticated', 'loggedInUser'])
  }
}
</script>

We create the computed properties by using the spread operator () to extract the getters from mapGetters. Then using isAuthenticated, we display the user menu or links to login or register depending on whether the user is logged in or not. Also, we use loggedInUser to display the authenticated user username.

Now, if we give our app a refresh, we should see something similar to below:

User log in

Now let’s allow returning users ability to login. Create a new login.vue file inside the pages directory and paste the code below in it:

// pages/login.vue

<template>
  <section class="section">
    <div class="container">
      <div class="columns">
        <div class="column is-4 is-offset-4">
          <h2 class="title has-text-centered">Welcome back!</h2>

          <Notification :message="error" v-if="error"/>

          <form method="post" @submit.prevent="login">
            <div class="field">
              <label class="label">Email</label>
              <div class="control">
                <input
                  type="email"
                  class="input"
                  name="email"
                  v-model="email"
                >
              </div>
            </div>
            <div class="field">
              <label class="label">Password</label>
              <div class="control">
                <input
                  type="password"
                  class="input"
                  name="password"
                  v-model="password"
                >
              </div>
            </div>
            <div class="control">
              <button type="submit" class="button is-dark is-fullwidth">Log In</button>
            </div>
          </form>
          <div class="has-text-centered" style="margin-top: 20px">
            <p>
              Don't have an account? <nuxt-link to="/register">Register</nuxt-link>
            </p>
          </div>
        </div>
      </div>
    </div>
  </section>
</template>

<script>
import Notification from '~/components/Notification'

export default {
  components: {
    Notification,
  },

  data() {
    return {
      email: '',
      password: '',
      error: null
    }
  },

  methods: {
    async login() {
      try {
        await this.$auth.loginWith('local', {
          data: {
            email: this.email,
            password: this.password
          }
        })

        this.$router.push('/')
      } catch (e) {
        this.error = e.response.data.message
      }
    }
  }
}
</script>

This is quite similar to the register page. The form contains two fields: email and password. When the form is submitted, a login method will be called. Using the Auth module loginWith() and passing along the user data, we log the user in. If the authentication was successful, we redirect the user to the homepage. Otherwise set error to the error message gotten from the API response. Again, we are using the Notification component from earlier on to display the error message.

Displaying the user profile

Let’s allow logged in user to be able to view their profile. Create a new profile.vue file inside the pages directory and paste the code below in it:

// pages/profile.vue

<template>
  <section class="section">
    <div class="container">
      <h2 class="title">My Profile</h2>
      <div class="content">
        <p>
          <strong>Username:</strong>
          {{ loggedInUser.username }}
        </p>
        <p>
          <strong>Email:</strong>
          {{ loggedInUser.email }}
        </p>
      </div>
    </div>
  </section>
</template>

<script>
import { mapGetters } from 'vuex'

export default {
  computed: {
    ...mapGetters(['loggedInUser'])
  }
}
</script>

This is pretty straightforward, as we are using the loggedInUser getter from earlier on to display display the user details.

Clicking on the My Profile link should result in something similar to below:

Logging user out

Update the logout link inside the Navbar component as below:

// components/Navbar.vue

<a class="navbar-item" @click="logout">Logout</a>

When the logout link is click, it will trigger a logout method.

Next, let’s add the logout method inside the script section of the Navbar component:

// components/Navbar.vue

methods: {
  async logout() {
    await this.$auth.logout();
  },
},

We call the logout() of the Auth module. This will simply delete the user’s token from localstorage and redirect the user to the homepage.

Restricting the profile page to only logged in users

As it stands now, anybody can visit the profile page and if the user is not logged in, it will result in error as below:

To fix this, we need to restrict the profile page to only logged in users. Luckily for us, we can easily achieve that with the Auth module. The Auth module comes with an auth middleware, which we can use in this scenario.

So let’s add the auth middleware to the profile page, update the script section as below:

// pages/profile.vue

<script>
...

export default {
  middleware: 'auth',
 ...
}
</script>

Now when a user that is not logged in tries to visit the profile page, the user will be redirected to the login page.

Creating a guest middleware

Again as it stand, even as a logged in user, we can still access the login and register pages. One way to fix that is to restrict login and register pages to only users that are not logged in. We can do that by creating a guest middleware. Inside the middleware directory, create a new guest.js file and paste the code below in it:

// middleware/guest.js

export default function ({ store, redirect }) {
  if (store.state.auth.loggedIn) {
    return redirect('/')
  }
}

A middleware accepts the context as it first argument. So we extract store and redirect from the context. We check if the user is logged in then redirect the user to the homepage. Otherwise, we allow the normal execution of the request.

Next, let’s make use of this middleware. Update the script section of both login and register as below:

<script>
...

export default {
  middleware: 'guest',
 ...
}
</script>

Now everything should be working as expected.

Conclusion

That’s it! In this tutorial, we looked at how to implement authentication in a Nuxt.js application using the Auth module. We also saw how to keep the authentication flow sleek by making use of middleware.

To learn more and the Auth module, checkout the docs.

NBB: Ad-hoc CLJS Scripting on Node.js

Nbb

Not babashka. Node.js babashka!?

Ad-hoc CLJS scripting on Node.js.

Status

Experimental. Please report issues here.

Goals and features

Nbb's main goal is to make it easy to get started with ad hoc CLJS scripting on Node.js.

Additional goals and features are:

  • Fast startup without relying on a custom version of Node.js.
  • Small artifact (current size is around 1.2MB).
  • First class macros.
  • Support building small TUI apps using Reagent.
  • Complement babashka with libraries from the Node.js ecosystem.

Requirements

Nbb requires Node.js v12 or newer.

How does this tool work?

CLJS code is evaluated through SCI, the same interpreter that powers babashka. Because SCI works with advanced compilation, the bundle size, especially when combined with other dependencies, is smaller than what you get with self-hosted CLJS. That makes startup faster. The trade-off is that execution is less performant and that only a subset of CLJS is available (e.g. no deftype, yet).

Usage

Install nbb from NPM:

$ npm install nbb -g

Omit -g for a local install.

Try out an expression:

$ nbb -e '(+ 1 2 3)'
6

And then install some other NPM libraries to use in the script. E.g.:

$ npm install csv-parse shelljs zx

Create a script which uses the NPM libraries:

(ns script
  (:require ["csv-parse/lib/sync$default" :as csv-parse]
            ["fs" :as fs]
            ["path" :as path]
            ["shelljs$default" :as sh]
            ["term-size$default" :as term-size]
            ["zx$default" :as zx]
            ["zx$fs" :as zxfs]
            [nbb.core :refer [*file*]]))

(prn (path/resolve "."))

(prn (term-size))

(println (count (str (fs/readFileSync *file*))))

(prn (sh/ls "."))

(prn (csv-parse "foo,bar"))

(prn (zxfs/existsSync *file*))

(zx/$ #js ["ls"])

Call the script:

$ nbb script.cljs
"/private/tmp/test-script"
#js {:columns 216, :rows 47}
510

Macros

Nbb has first class support for macros: you can define them right inside your .cljs file, like you are used to from JVM Clojure. Consider the plet macro to make working with promises more palatable:

(defmacro plet
  [bindings & body]
  (let [binding-pairs (reverse (partition 2 bindings))
        body (cons 'do body)]
    (reduce (fn [body [sym expr]]
              (let [expr (list '.resolve 'js/Promise expr)]
                (list '.then expr (list 'clojure.core/fn (vector sym)
                                        body))))
            body
            binding-pairs)))

Using this macro we can look async code more like sync code. Consider this puppeteer example:

(-> (.launch puppeteer)
      (.then (fn [browser]
               (-> (.newPage browser)
                   (.then (fn [page]
                            (-> (.goto page "https://clojure.org")
                                (.then #(.screenshot page #js{:path "screenshot.png"}))
                                (.catch #(js/console.log %))
                                (.then #(.close browser)))))))))

Using plet this becomes:

(plet [browser (.launch puppeteer)
       page (.newPage browser)
       _ (.goto page "https://clojure.org")
       _ (-> (.screenshot page #js{:path "screenshot.png"})
             (.catch #(js/console.log %)))]
      (.close browser))

See the puppeteer example for the full code.

Since v0.0.36, nbb includes promesa which is a library to deal with promises. The above plet macro is similar to promesa.core/let.

Startup time

$ time nbb -e '(+ 1 2 3)'
6
nbb -e '(+ 1 2 3)'   0.17s  user 0.02s system 109% cpu 0.168 total

The baseline startup time for a script is about 170ms seconds on my laptop. When invoked via npx this adds another 300ms or so, so for faster startup, either use a globally installed nbb or use $(npm bin)/nbb script.cljs to bypass npx.

Dependencies

NPM dependencies

Nbb does not depend on any NPM dependencies. All NPM libraries loaded by a script are resolved relative to that script. When using the Reagent module, React is resolved in the same way as any other NPM library.

Classpath

To load .cljs files from local paths or dependencies, you can use the --classpath argument. The current dir is added to the classpath automatically. So if there is a file foo/bar.cljs relative to your current dir, then you can load it via (:require [foo.bar :as fb]). Note that nbb uses the same naming conventions for namespaces and directories as other Clojure tools: foo-bar in the namespace name becomes foo_bar in the directory name.

To load dependencies from the Clojure ecosystem, you can use the Clojure CLI or babashka to download them and produce a classpath:

$ classpath="$(clojure -A:nbb -Spath -Sdeps '{:aliases {:nbb {:replace-deps {com.github.seancorfield/honeysql {:git/tag "v2.0.0-rc5" :git/sha "01c3a55"}}}}}')"

and then feed it to the --classpath argument:

$ nbb --classpath "$classpath" -e "(require '[honey.sql :as sql]) (sql/format {:select :foo :from :bar :where [:= :baz 2]})"
["SELECT foo FROM bar WHERE baz = ?" 2]

Currently nbb only reads from directories, not jar files, so you are encouraged to use git libs. Support for .jar files will be added later.

Current file

The name of the file that is currently being executed is available via nbb.core/*file* or on the metadata of vars:

(ns foo
  (:require [nbb.core :refer [*file*]]))

(prn *file*) ;; "/private/tmp/foo.cljs"

(defn f [])
(prn (:file (meta #'f))) ;; "/private/tmp/foo.cljs"

Reagent

Nbb includes reagent.core which will be lazily loaded when required. You can use this together with ink to create a TUI application:

$ npm install ink

ink-demo.cljs:

(ns ink-demo
  (:require ["ink" :refer [render Text]]
            [reagent.core :as r]))

(defonce state (r/atom 0))

(doseq [n (range 1 11)]
  (js/setTimeout #(swap! state inc) (* n 500)))

(defn hello []
  [:> Text {:color "green"} "Hello, world! " @state])

(render (r/as-element [hello]))

Promesa

Working with callbacks and promises can become tedious. Since nbb v0.0.36 the promesa.core namespace is included with the let and do! macros. An example:

(ns prom
  (:require [promesa.core :as p]))

(defn sleep [ms]
  (js/Promise.
   (fn [resolve _]
     (js/setTimeout resolve ms))))

(defn do-stuff
  []
  (p/do!
   (println "Doing stuff which takes a while")
   (sleep 1000)
   1))

(p/let [a (do-stuff)
        b (inc a)
        c (do-stuff)
        d (+ b c)]
  (prn d))
$ nbb prom.cljs
Doing stuff which takes a while
Doing stuff which takes a while
3

Also see API docs.

Js-interop

Since nbb v0.0.75 applied-science/js-interop is available:

(ns example
  (:require [applied-science.js-interop :as j]))

(def o (j/lit {:a 1 :b 2 :c {:d 1}}))

(prn (j/select-keys o [:a :b])) ;; #js {:a 1, :b 2}
(prn (j/get-in o [:c :d])) ;; 1

Most of this library is supported in nbb, except the following:

  • destructuring using :syms
  • property access using .-x notation. In nbb, you must use keywords.

See the example of what is currently supported.

Examples

See the examples directory for small examples.

How to start an electric scooter facility/fleet in a university campus/IT park

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?

Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.

Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.

To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.

What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.

Micro-mobility: What it is

micro-mobility

You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.

Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.

You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.

You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.

As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.

Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.

As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.

All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.

This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!

Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.

Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.

How micro-mobility can benefit you

benefits-micromobility

What advantages can you get from micro-mobility? Let’s take a deeper look into this question.

Micro-mobility can offer several advantages to the people on your campus, e.g.:

  • Affordability: Shared e-scooters are cheaper than other mass transportation options. Remember that the people on your campus will use them on a shared basis, and they will pay for their short commutes only. Well, depending on your operating model, you might even let them use shared e-scooters or e-bikes for free!
  • Convenience: Users don’t need to worry about finding parking spots for shared e-scooters since these are small. They can easily travel from point A to point B on your campus with the help of these e-scooters.
  • Environmentally sustainable: Shared e-scooters reduce the carbon footprint, moreover, they decongest the roads. Statistics from the pilot programs in cities like Portland and Denver showimpressive gains around this key aspect.
  • Safety: This one’s obvious, isn’t it? When people on your campus use small e-scooters or e-bikes instead of cars, the problem of overspeeding will disappear. you will see fewer accidents.

Best Electric Bikes and Scooters for Rental Business or Campus Facility

The electric scooter revolution has caught on super-fast taking many cities across the globe by storm. eScooters, a renovated version of old-school scooters now turned into electric vehicles are an environmentally friendly solution to current on-demand commute problems. They work on engines, like cars, enabling short traveling distances without hassle. The result is that these groundbreaking electric machines can now provide faster transport for less — cheaper than Uber and faster than Metro.

Since they are durable, fast, easy to operate and maintain, and are more convenient to park compared to four-wheelers, the eScooters trend has and continues to spike interest as a promising growth area. Several companies and universities are increasingly setting up shop to provide eScooter services realizing a would-be profitable business model and a ready customer base that is university students or residents in need of faster and cheap travel going about their business in school, town, and other surrounding areas.

Electric Scooters Trends and Statistics

In many countries including the U.S., Canada, Mexico, U.K., Germany, France, China, Japan, India, Brazil and Mexico and more, a growing number of eScooter users both locals and tourists can now be seen effortlessly passing lines of drivers stuck in the endless and unmoving traffic.

A recent report by McKinsey revealed that the E-Scooter industry will be worth― $200 billion to $300 billion in the United States, $100 billion to $150 billion in Europe, and $30 billion to $50 billion in China in 2030. The e-Scooter revenue model will also spike and is projected to rise by more than 20% amounting to approximately $5 billion.

And, with a necessity to move people away from high carbon prints, traffic and congestion issues brought about by car-centric transport systems in cities, more and more city planners are developing more bike/scooter lanes and adopting zero-emission plans. This is the force behind the booming electric scooter market and the numbers will only go higher and higher.

Companies that have taken advantage of the growing eScooter trend develop an appthat allows them to provide efficient eScooter services. Such an app enables them to be able to locate bike pick-up and drop points through fully integrated google maps.

List of Best Electric Bikes for Rental Business or Campus Facility 2020:

It’s clear that e scooters will increasingly become more common and the e-scooter business model will continue to grab the attention of manufacturers, investors, entrepreneurs. All this should go ahead with a quest to know what are some of the best electric bikes in the market especially for anyone who would want to get started in the electric bikes/scooters rental business.

We have done a comprehensive list of the best electric bikes! Each bike has been reviewed in depth and includes a full list of specs and a photo.

How long does it take to develop/build an app?

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.

Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.

There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.

To give you an idea of how long the app development process takes, here’s a short guide.

App Idea & Research

app-idea-research

_Average time spent: two to five weeks _

This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.

All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.

Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.

The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.

The outcomes of this stage are app prototypes and the minimum feasible product.
