How to Making A Single Page App without A Framework

The idea behind single page applications (SPA) is to create a smooth browsing experience like the one found in native desktop apps. All of the necessary code for the page is loaded only once and its content gets changed dynamically through JavaScript. If everything is done right the page shouldn't ever reload, unless the user refreshes it manually.

There are many frameworks for single page applications out there. First we had Backbone, then Angular, now React. It takes a lot of work to constantly learn and re-learn things (not to mention having to support old code you've written in a long forgotten framework). In some situations, like when your app idea isn't too complex, it is actually not that hard to create a single page app without using any external frameworks. Here is how to do it.

Note: To run this example after downloading it, you need a locally running webserver like Apache. Our demo uses AJAX so it will not work if you simply double-click index.html for security reasons.

The Idea

We will not be using a framework, but we will be using two libraries - jQuery for DOM manipulation and event handling, and Handlebars for templates. You can easily omit these if you wish to be even more minimal, but we will use them for the productivity gains they provide. They will be here long after the hip client-side framework of the day is forgotten.

The app that we will be building fetches product data from a JSON file, and displays it by rendering a grid of products with Handlebars. After the initial load, our app will stay on the same URL and listen for changes to the hash part with the hashchange event. To navigate around the app, we will simply change the hash. This has the added benefit that browser history will just work without extra effort on our part.

The Setup

Our project's folder

As you can see there isn't much in our project folder. We have the regular web app setup - HTML, JavaScript and CSS files, accompanied by a products.json containing data about the products in our shop and a folder with images of the products.

The Products JSON

The .json file is used to store data about each product for our SPA. This file can easily be replaced by a server-side script to fetch data from a real database.

products.json

[
  {
    "id": 1,
    "name": "Sony Xperia Z3",
    "price": 899,
    "specs": {
      "manufacturer": "Sony",
      "storage": 16,
      "os": "Android",
      "camera": 15
    },
    "description": "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam tristique ipsum in efficitur pharetra. Maecenas luctus ante in neque maximus, sed viverra sem posuere. Vestibulum lectus nisi, laoreet vel suscipit nec, feugiat at odio. Etiam eget tellus arcu.",
    "rating": 4,
    "image": {
      "small": "/images/sony-xperia-z3.jpg",
      "large": "/images/sony-xperia-z3-large.jpg"
    }
  },
  {
    "id": 2,
    "name": "Iphone 6",
    "price": 899,
    "specs": {
      "manufacturer": "Apple",
      "storage": 16,
      "os": "iOS",
      "camera": 8
    },
    "description": "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam tristique ipsum in efficitur pharetra. Maecenas luctus ante in neque maximus, sed viverra sem posuere. Vestibulum lectus nisi, laoreet vel suscipit nec, feugiat at odio. Etiam eget tellus arcu.",
    "rating": 4,
    "image": {
      "small": "/images/iphone6.jpg",
      "large": "/images/iphone6-large.jpg"
    }
  }
]

The HTML

In our html file we have several divs sharing the same class "page". Those are the different pages (or as they are called in SPA - states) our app can show. However, on page load all of these are hidden via CSS and need the JavaScript to show them. The idea is that only one page can be visible at a time and our script is the one to decide which one it is.

index.html

<div class="main-content">

    <div class="all-products page">

        <h3>Our products</h3>

        <div class="filters">
            <form>
                Checkboxes here
            </form>
        </div>

    <ul class="products-list">
      <script id="products-template" type="x-handlebars-template">​
        {{#each this}}
          <li data-index="{{id}}">
            <a href="#" class="product-photo"><img src="{{image.small}}" height="130" alt="{{name}}"/></a>
            <h2><a href="#"> {{name}} </a></h2>
            <ul class="product-description">
              <li><span>Manufacturer: </span>{{specs.manufacturer}}</li>
              <li><span>Storage: </span>{{specs.storage}} GB</li>
              <li><span>OS: </span>{{specs.os}}</li>
              <li><span>Camera: </span>{{specs.camera}} Mpx</li>
            </ul>
            <button>Buy Now!</button>
            <p class="product-price">{{price}}$</p>
            <div class="highlight"></div>
          </li>
        {{/each}}
      </script>

    </ul>

    </div>

    <div class="single-product page">

        <div class="overlay"></div>

        <div class="preview-large">
            <h3>Single product view</h3>
            <img src=""/>
            <p></p>

            <span class="close">&times;</span>
        </div>

    </div>

    <div class="error page">
        <h3>Sorry, something went wrong :(</h3>
    </div>

</div>

We have three pages: all-products (the product listing), single-product (the individual product page) and error.

The all-products page consists of a title, a form containing checkboxes for filtering and a <ul> tag with the class "products-list". This list is generated with handlebars using the data stored in products.json, creating a <li> for each entry in the json. Here is the result:

rsz_screenshot_-_13012015_-_145617.jpg

The Products

Single-product is used to show information about only one product. It is empty and hidden on page load. When the appropriate hash address is reached, it is populated with product data and shown.

The error page consist of only an error message to let you know when you've reached a faulty address.

The JavaScript Code

First, lets make a quick preview of the functions and what they do.

script.js

$(function () {

    checkboxes.click(function () {
        // The checkboxes in our app serve the purpose of filters.
        // Here on every click we add or remove filtering criteria from a filters object.

        // Then we call this function which writes the filtering criteria in the url hash.
        createQueryHash(filters);
    });

    $.getJSON( "products.json", function( data ) {
        // Get data about our products from products.json.

        // Call a function that will turn that data into HTML.
        generateAllProductsHTML(data);

        // Manually trigger a hashchange to start the app.
        $(window).trigger('hashchange');
    });

    $(window).on('hashchange', function(){
        // On every hash change the render function is called with the new hash.
        // This is how the navigation of our app happens.
        render(decodeURI(window.location.hash));
    });

    function render(url) {
        // This function decides what type of page to show 
        // depending on the current url hash value.
    }

    function generateAllProductsHTML(data){
        // Uses Handlebars to create a list of products using the provided data.
        // This function is called only once on page load.
    }

    function renderProductsPage(data){
        // Hides and shows products in the All Products Page depending on the data it recieves.
    }

    function renderSingleProductPage(index, data){
        // Shows the Single Product Page with appropriate data.
    }

    function renderFilterResults(filters, products){
        // Crates an object with filtered products and passes it to renderProductsPage.
        renderProductsPage(results);
    }

    function renderErrorPage(){
        // Shows the error page.
    }

    function createQueryHash(filters){
        // Get the filters object, turn it into a string and write it into the hash.
    }

});

Remember that the concept of SPA is to not have any loads going on while the app is running. That's why after the initial page load we want to stay on the same page, where everything we need has already been fetched by the server.

However, we still want to be able to go somewhere in the app and, for example, copy the url and send it to a friend. If we never change the app's address they will just get the app the way it looks in the beginning, not what you wanted to share with them. To solve this problem we write information about the state of the app in the url as #hash. Hashes don't cause the page to reload and are easily accessible and manipulated.

On every hashchange we call this:

function render(url) {

        // Get the keyword from the url.
        var temp = url.split('/')[0];

        // Hide whatever page is currently shown.
        $('.main-content .page').removeClass('visible');

        var map = {

            // The Homepage.
            '': function() {

                // Clear the filters object, uncheck all checkboxes, show all the products
                filters = {};
                checkboxes.prop('checked',false);

                renderProductsPage(products);
            },

            // Single Products page.
            '#product': function() {

                // Get the index of which product we want to show and call the appropriate function.
                var index = url.split('#product/')[1].trim();

                renderSingleProductPage(index, products);
            },

            // Page with filtered products
            '#filter': function() {

                // Grab the string after the '#filter/' keyword. Call the filtering function.
                url = url.split('#filter/')[1].trim();

                // Try and parse the filters object from the query string.
                try {
                    filters = JSON.parse(url);
                }
                // If it isn't a valid json, go back to homepage ( the rest of the code won't be executed ).
                catch(err) {
                    window.location.hash = '#';
                }

                renderFilterResults(filters, products);
            }

        };

        // Execute the needed function depending on the url keyword (stored in temp).
        if(map[temp]){
            map[temp]();
        }
        // If the keyword isn't listed in the above - render the error page.
        else {
            renderErrorPage();
        }

    }

This function takes into consideration the beginning string of our hash, decides what page needs to be shown and calls the according functions.

For example if the hash is '#filter/{"storage":["16"],"camera":["5"]}', our codeword is '#filter'. Now the render function knows we want to see a page with the filtered products list and will navigate us to it. The rest of the hash will be parsed into an object and a page with the filtered products will be shown, changing the state of the app.

This is called only once on start up and turns our JSON into actual HTML5 content via handlebars.

function generateAllProductsHTML(data){

    var list = $('.all-products .products-list');

    var theTemplateScript = $("#products-template").html();
    //Compile the template​
    var theTemplate = Handlebars.compile (theTemplateScript);
    list.append (theTemplate(data));

    // Each products has a data-index attribute.
    // On click change the url hash to open up a preview for this product only.
    // Remember: every hashchange triggers the render function.
    list.find('li').on('click', function (e) {
      e.preventDefault();

      var productIndex = $(this).data('index');

      window.location.hash = 'product/' + productIndex;
    })
  }

This function receives an object containing only those products we want to show and displays them.

function renderProductsPage(data){

    var page = $('.all-products'),
      allProducts = $('.all-products .products-list > li');

    // Hide all the products in the products list.
    allProducts.addClass('hidden');

    // Iterate over all of the products.
    // If their ID is somewhere in the data object remove the hidden class to reveal them.
    allProducts.each(function () {

      var that = $(this);

      data.forEach(function (item) {
        if(that.data('index') == item.id){
          that.removeClass('hidden');
        }
      });
    });

    // Show the page itself.
    // (the render function hides all pages so we need to show the one we want).
    page.addClass('visible');

  }

Shows the single product preview page:

function renderSingleProductPage(index, data){

    var page = $('.single-product'),
      container = $('.preview-large');

    // Find the wanted product by iterating the data object and searching for the chosen index.
    if(data.length){
      data.forEach(function (item) {
        if(item.id == index){
          // Populate '.preview-large' with the chosen product's data.
          container.find('h3').text(item.name);
          container.find('img').attr('src', item.image.large);
          container.find('p').text(item.description);
        }
      });
    }

    // Show the page.
    page.addClass('visible');

  }

Takes all the products, filters them based on our query and returns an object with the results.

function renderFilterResults(filters, products){

      // This array contains all the possible filter criteria.
    var criteria = ['manufacturer','storage','os','camera'],
      results = [],
      isFiltered = false;

    // Uncheck all the checkboxes.
    // We will be checking them again one by one.
    checkboxes.prop('checked', false);

    criteria.forEach(function (c) {

      // Check if each of the possible filter criteria is actually in the filters object.
      if(filters[c] && filters[c].length){

        // After we've filtered the products once, we want to keep filtering them.
        // That's why we make the object we search in (products) to equal the one with the results.
        // Then the results array is cleared, so it can be filled with the newly filtered data.
        if(isFiltered){
          products = results;
          results = [];
        }

        // In these nested 'for loops' we will iterate over the filters and the products
        // and check if they contain the same values (the ones we are filtering by).

        // Iterate over the entries inside filters.criteria (remember each criteria contains an array).
        filters[c].forEach(function (filter) {

          // Iterate over the products.
          products.forEach(function (item){

            // If the product has the same specification value as the one in the filter
            // push it inside the results array and mark the isFiltered flag true.

            if(typeof item.specs[c] == 'number'){
              if(item.specs[c] == filter){
                results.push(item);
                isFiltered = true;
              }
            }

            if(typeof item.specs[c] == 'string'){
              if(item.specs[c].toLowerCase().indexOf(filter) != -1){
                results.push(item);
                isFiltered = true;
              }
            }

          });

          // Here we can make the checkboxes representing the filters true,
          // keeping the app up to date.
          if(c && filter){
            $('input[name='+c+'][value='+filter+']').prop('checked',true);
          }
        });
      }

    });

    // Call the renderProductsPage.
    // As it's argument give the object with filtered products.
    renderProductsPage(results);
  }

Shows the error state:

function renderErrorPage(){
    var page = $('.error');
    page.addClass('visible');
  }

Stringifies the filters object and writes it into the hash.

function createQueryHash(filters){

    // Here we check if filters isn't empty.
    if(!$.isEmptyObject(filters)){
      // Stringify the object via JSON.stringify and write it after the '#filter' keyword.
      window.location.hash = '#filter/' + JSON.stringify(filters);
    }
    else{
      // If it's empty change the hash to '#' (the homepage).
      window.location.hash = '#';
    }

  }

Conclusion

Single page applications are perfect when you want give your project a more dynamic and fluid feel, and with the help of some clever design choices you can offer your visitors a polished, pleasant experience.

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.

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.

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.
