If you are unfamiliar with how to build a progressive web app, it might seem like an intimidating process. But when it comes to a progressive web app builder, the overall process has become something that we are especially familiar with! Here at Split Reef, as a progressive web app development company, we are always happy to break down parts of the development process to help clients and those interested to know a little bit of what goes in to what we do.

What is a Progressive Web App?

First off, what is a progressive web app? Progressive web apps essentially take advantage of the latest technologies that are available. They “use modern web capabilities to deliver an app-like user experience.” A progressive web app that has been created by a progressive web app builder is responsive, app-like, and extremely discoverable.

They combine the best of both web and mobile apps for a user and work in favor of the progressive web app development company that has been working on them by helping to ease the overall building process.

How to Build a Progressive Web App

So how does a progressive web app builder actually go about building a progressive web app? There are a number of steps that need to be taken, so we will explore a few of the steps that are taken throughout the process to help you get a better understanding of how a progressive web app builder creates a progressive web app.

App Interface

When it comes to a progressive web app development company or a singular progressive web app builder creating a progressive web app, one of the first things they will do is to create a file name index.html. This code will look similar to this:

“<!doctype html>

<html lang=”en”>

<head>

<meta charset=”utf-8″>

<title>Hello World</title>

<link rel=”stylesheet” href=”css/style.css”>

<meta name=”viewport” content=”width=device-width, initial-scale=1.0″>

<body class=”fullscreen”>

<div class=”container”>

<h1 class=”title”>Hello World!</h1>

</div>

</body>

</html>”

The index.html file is very standard across progressive web apps. It serves as a stylesheet and helps to fulfill two requirements that a progressive web app builder must meet in a progressive web app. These two requirements are:

  • A progressive web app should be able to display some kind of content even if JavaScript is disabled.
  • A progressive web app should be very responsive and can be displayed properly on a wide variety of devices. The web app essentially needs to be mobile friendly.

Other pages or pieces of code will be added by a progressive web app builder throughout the process of the web app creation. One of those includes the includes the Page.js. The Page.js allows them to access the ViewModel. ViewModel is a JavaScript piece that will be used throughout the entire progressive web app.

Service Worker

Another crucial step taken by a progressive web app development company in the web app process is to add a service worker. A service worker is a script that will run in the background of a progressive web app to perform tasks and functions that do not need any user interaction. They work to take care of the more mundane and boring tasks so that the main app can function.

The service worker will usually be contained in the app root where it has access to all of the app files.

What Else?

While there are many other pieces to be found within the development of a progressive web app that a progressive web app builder works on, a few of the key parts include:

  • Web app manifest
  • Application shell
  • Offline test
  • Cross browser support

These all come at different points in the development process, but they are important to making sure a progressive web app is functioning as it should.
