Building a simple app using NodeJS, MongoDB, and ExpressJS

In this tutorial, we will build a simple app with Node.Js using ExpressJs framework and MongoDB.

So, first of all, this one is my first blog. I am currently working as a full stack developer but mostly I stuck with front-end today we are going to learn basic operation using Nodejs and MongoDB and also use nodemonI remember when I eventually picked up the courage to try, I had such a hard time understanding the documentation for Express, MongoDB, and Node.js that I gave up.

One month later, I finally understood how to work with these tools. Then, I decided to write a comprehensive blog so you won’t have to go through the same headache I went through.

one thing you need to install node …. I know you can do this…. nodejs

To check if you have Node installed, open up your command line and run the following code: $node -v You should get a version number if you have Node installed. If you don’t, you can install Node either

Start by creating a folder for this project. Feel free to call it anything you want. Once you navigate into it, run the npm init command. This command creates a package.json file which helps you manage dependencies that we install later in the blog.

The simplest way to use node is to run the node command and specify a path to a file. Let’s create a file called server.js to run node with

$ touch server.js

When the execute the server.js file, we want to make sure it’s running properly. To do so, simply write a console.log statement in server.js

console.log('pdp pdp pdp pdp')

Now, run node server.js in your command line and you should see the statement you logged — — pdp pdp pdp pdp

We first have to install Express before we can use it in our application. Installing Express is pretty easy. All we have to do is run an install command with Node package manager (npm), which comes bundled with Node. Run the npm install express --save command in your command line

$ npm install express --save

Once you’re done, you should see that npm has saved Express as a dependency in package.json

Next, we use express in server.js by requiring it.

const express = require('express');
const app = express();

The first thing we want to do is to create a server where browsers can connect. We can do so with the help of a listen method provided by Express:

app.listen(3000, function() {
  console.log('listening on 3000')
})

Now, run node server.js and navigate to localhost:3000 on your browser. You should see a message that says “cannot get /”. nice great news just kidding…… this is just beginning. The READ operation is performed by browsers whenever you visit a webpage. Under the hood, browsers send a GET request to the server to perform a READ operation. The reason we see the “cannot get /” error is because we have yet to send anything back to the browser from our server.

In Expressjs, we handle a GET request with the get method:

app.get(path, callback)

The first argument, path, is the path of the GET request. It’s anything that comes after your domain name.

When we’re visiting localhost:3000, our browsers are actually looking for localhost:3000/. The path argument in this case is /.The second argument is a callback function that tells the server what to do when the path is matched. It takes two arguments, a request object and a response object:

app.get('/', function (request, response) {
   // work here
})

For now, let’s write “PDP” back to the browser. We do so by using a sendmethod that comes with the response object:

app.get('/', function(req, res) {
   res.send('PDP')
})

I’m going to start writing in ES6 code and show you how to convert to ES6 along the way as well. First off, I’m replacing function() with an ES6 arrow function. The below code is the same as the above code:

app.get('/', (req, res) => {
   res.send('PDP') 
})

Now, restart your server by doing the following:

1. Stop the current server by hitting CTRL + C in the command line.
2. Run node server.js again.

Then, navigate to localhost:3000 on your browser. You should be able to see a string that says “PDP”.

Great. Let’s change our app so we serve an index.html page back to the browser instead. To do so, we use the sendFile method that’s provided by the res object.

res.sendFile(__dirname + '/index.html')

In the sendFile method above, we told Express to serve an index.html file that can be found in the root of your project folder. We don’t have that file yet. Let’s make it now.

touch index.html

Let’s put some text in our index.html file as well:

 
 
   
   MY APP
 
 
   May Node and Express be with you.
 
 

Restart your server and refresh your browser. You should be able to see the results of your HTML file now.

This is how Express handles a GET request (READ operation) in a nutshell.

At this point, you probably have realized that you need to restart your server whenever you make a change to server.js. This is process is incredibly tedious, so let’s take a quick detour and streamline it by using a package called nodemon.

Nodemon restarts the server automatically whenever you save a file that the server uses. We can install Nodemon by using the following command:

$ npm install nodemon --save-dev

Note: The reason we’re using a --save-dev flag here is because we’re only using Nodemon when we’re developing. This flag would save Nodemon as a devDependency in your package.json file.

Moving on, Nodemon behaves exactly the same as node, which means we can run our server by calling nodemon server.js. However, we can’t do it in the command line right now because Nodemon isn’t installed with a -g flag.

There’s one other way to run Nodemon — we can execute Nodemon from the node_modules folder. The code looks like this:

$ ./node_modules/.bin/nodemon server.js

That’s a handful to type. One way to make it simpler is to create a script key in package.json.

"scripts": {
  "dev": "nodemon server.js"
}

Now, you can run npm run dev to trigger nodemon server.js.

Back to the main topic. We’re going to cover the CREATE operation next.

The CREATE operation is only performed by the browser if a POSTrequest is sent to the server. This POST request can be triggered either with JavaScript or through a `` element.

Let’s find out how to use a `` element to create new entries for our Star Wars quote app for this part of the tutorial.

To do so, you first have to create a `` element and add it to your index.html file. You need to have three things on this form element:

1. An action attribute,
2. a method attribute,
3. and name attributes on all ` elements within the form.

   
   
   Submit
 

The action attribute tells the browser where to navigate to in our Express app. In this case, we’re navigating to /quotes. The methodattribute tells the browser what request to send. In this case, it’s a POST request.

On our server, we can handle this POST request with a post method that Express provides. It takes the same arguments as the GET method:

app.post('/quotes', (req, res) => { 
  console.log('Hellooooooooooooooooo!')
})

Restart your server (hopefully you’ve set up Nodemon so it restarts automatically) and refresh your browser. Then, enter something into your form element. You should be able to see Hellooooooooooooooooo!in your command line.

Great, we know that Express is handling the form for us right now. The next question is, how do we get the input values with Express?

Turns out, Express doesn’t handle reading data from the ``element on it’s own. We have to add another package called body-parserto gain this functionality.

$ npm install body-parser --save

Express allows us to add middleware like body-parser to our application with the use method. You’ll hear the term middleware a lot when dealing with Express. These things are basically plugins that change the request or response object before they get handled by our application. Make sure you place body-parser before your CRUD handlers!

const express = require('express')
const bodyParser= require('body-parser') 
const app = express()  
app.use(bodyParser.urlencoded({extended: true}))

The urlencoded method within body-parser tells body-parser to extract data from the `` element and add them to the body property in the requestobject.

Now, you should be able to see everything in the form field within the req.body object. Try doing a console.log and see what it is!

app.post('/quotes', (req, res) => {
 console.log(req.body) 
})
You should be able to get an object similar to the following in your command line:
{
name: 'pdp',
quotes: 'pdp psr pdp'
}

Enter the Database, MongoDB

We first have to install MongoDB through npm if we want to use it as our database.

$ npm install mongodb --save

Once installed, we can connect to MongoDB through the MongoClient’s connect method as shown in the code below:

const MongoClient = require('mongodb').MongoClient  MongoClient.connect('link-to-mongodb', (err, database) => {
   // ... start the server 
})

The next part is to get the correct link to our database. Most people store their databases on cloud services like mLab (formerly MongoLab). We’re going to do same as well.

So, go ahead and create an account with mLab. (It’s free.) Once you’re done, create a new MongoDB Deployment

Once you’re done creating the deployment, head into it and create a database user and database password. Remember the database user and database password because you’re going to use it to connect the database you’ve just created.

Finally, grab the MongoDB url and add it to your MongoClient.connectmethod. Make sure you use your database user and password!

Next, we want to start our servers only when the database is connected. Hence, let’s move app.listen into the connect method. We’re also going to create a db variable to allow us to use the database when we handle requests from the browser.

const client = new MongoClient(url, { useNewUrlParser: true });
client.connect((err, database) => {
 db = database.db("test")
 app.listen(3000, function () {
 })
})

We’re done setting up MongoDB. Now, let’s create a quotes collection to store quotes for our application.

By the way, a collection is a named location to store stuff. You can create as many collections as you want. It can be things like “products”, “quotes”, “groceries”, or any other labels you choose.

We can create the quotes collection by using the string quotes while calling MongoDB’s db.collection() method. While creating the quotes collection, we can also save our first entry into MongoDB with the savemethod simultaneously.

Once we’re done saving, we have to redirect the user somewhere (or they’ll be stuck waiting forever for our server to move). In this case, we’re going to redirect them back to /, which causes their browsers to

app.post('/quotes', (req, res) => {   db.collection('quotes').save(req.body, (err, result) => {
     if (err) return console.log(err)
     console.log('saved to database')
     res.redirect('/')
   })
 })

Now, if you enter something into the `` element, you’ll be able to see an entry in your MongoDB collection.

oh, sorry button is also there maybe I made mistake but leave it now…

Whoohoo! Since we already have some quotes in the collection, why not try showing them to our user when they land on our page?

We have to do two things to show the quotes stored in mLab to our users.

1. Get quotes from mLab.
2. Use a template engine to display the quotes.

Let’s go one step at a time.

We can get the quotes from mLab by using the find method that’s available in the collection method.

app.get('/', (req, res) => {
   var cursor = db.collection('quotes').find() 
})

The find method returns a cursor (a Mongo object) that probably doesn’t make sense if you console.log it out. this cursor object contains all quotes from our database. It also contains a bunch of other properties and methods that allow us to work with data easily. One such method is the toArraymethod.The toArray method takes in a callback function that allows us to do stuff with quotes we retrieved from mLab. Let’s try doing a console.log() for the results and see what we get!

var cursor = db.collection('quotes').find().toArray(function(err, result){
    console.log('kya baat bhai mast')
    if (err) { return console.log(err) }
    console.log('haanbhai', result)
    res.render('index.ejs', {quotes: result})
  })

We can’t serve our index.html file and expect quotes to magically appear because there’s no way to add dynamic content to a HTML file. What we can do instead, is to use template engines to help us out. Some popular template engines include Jade, Embedded JavaScript and Nunjucks.

I’ve written extensively about the how and why of template engines in a separate post. You might want to check it out if you have no idea what template engines are. I personally use (and recommend) Nunjucks as my template engine of choice. Feel free to check out the post to find out why.

For this tutorial, we’re going to use Embedded JavaScript (ejs) as our template engine because it’s the easiest to start with. You’ll find it familiar from the get-go since you already know HTML and JavaScript.

We can use EJS by first installing it, then setting the view engine in Express to ejs.

$ npm install ejs --save
code in server.js
app.set('view engine', 'ejs')

Once the view engine is set, we can begin generating the HTML with our quotes. This process is also called rendering. We can use the render object built into the response object render to do so. It has the following syntax:

res.render(view, locals)

The first parameter, view, is the name of the file we’re rendering. This file must be placed within a views folder.

The second parameter, locals, is an object that passes data into the view.

Let’s first create an index.ejs file within the views folder so we can start populating data.

$ mkdir views
$ touch views/index.ejs

Now, place the following code within index.ejs.

See what I mean when I say you’ll find it familiar? In EJS, you can write JavaScript within  tags. You can also output JavaScript as strings if you use the  tags.

Here, you can see that we’re basically looping through the quotes array and creating strings with quotes[i].name and quotes[i].quote.

One more thing to do before we move on from the index.ejs file. Remember to copy the `` element from the index.html file into this file as well. The complete index.ejs file so far should be:

  
  MY APP


  May Node and Express be with you. and pdp ki blessing


  
    
      
      
    
  
  


    
    
    Submit
  

Finally, we have to render this index.ejs file when handling the GETrequest. Here, we’re setting the results (an array) as the quotes array we used in index.ejs above.

app.get('/', (req, res) => {
  // res.sendFile(__dirname + '/index.html');
  var cursor = db.collection('quotes').find().toArray(function(err, result){
    console.log('kya baat bhai mast')
    if (err) { return console.log(err) }
    console.log('haanbhai', result)
    res.render('index.ejs', {quotes: result})
  })
})

Now, refresh your browser and you should be able to see quotes.

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

_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.

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

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

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.
