This time I will show you how to use @angular/cli V6.0 to develop PWA applications, and what are the precautions for using @angular/cli V6.0 to develop PWA applications. The following are practical cases. Let’s take a look.

What is PWA

PWA (Progressive Web App) utilizes TLS, webapp manifests and service workers to enable applications to install and use it offline. In other words, a PWA is like a native app on your phone, but it's built using web technologies like HTML5, JavaScript, and CSS3. When built correctly, PWAs are indistinguishable from native apps. The main features of PWA include the following three points:

Angular has officially released V6.0, and we can already use the corresponding @angular/cli V6.0 to directly develop PWA applications. Not much to say below, let’s take a look at the detailed introduction.

Step one: Install @angular/cli V6.0If you have an old version on your machine, please uninstall it first.

Open your terminal and execute:

npm install -g @angular/cli

Copy after login

After successful installation, use ng -v to check the version number:

##Second step: new an empty project

Execution:

ng new test-ng-pwa

Copy after login

After the creation is successful, take a look at the project and execute:

ng serve --open

Copy after login

Seeing this interface in the browser means everything is OK:

Step 3: Add PWA support

Stop the project, and then execute it in the terminal:

ng add @angular/pwa

Copy after login

The effect is as follows:

##Because the built-in Server of @angular/cli is compiled with --prod Service-worker was not supported at that time, so a third-party lite-server was installed on it. Its official documentation is here:

https://npmjs.com/package/lite-server, please execute :

npm install lite-server --save-dev
npm install lite-server --global

Copy after login

After installation, execute:

npx ng build --prod && lite-server --baseDir dist/test-ng-pwa

Copy after login

Then open your browser to access port 3000. You can see that the service-worker has started successfully:

You can now add the application to the desktop:

This is the effect on Windows ：

The latest versions of Linux, iOS,

Android, and ChromeOS are all supported. Try it yourself!
