The index HTML augmentation within the PWA schematic now uses the Node.js promise-based pipeline helper to reduce the complexity of the code when using the parse5 streaming rewriter. This removes a noticeable amount of code as well as removing the need to manually wrap the result in a Promise.
@angular/pwa
This is a schematic for adding Progressive Web App support to an Angular project. Run the schematic with the Angular CLI:
ng add @angular/pwa --project <project-name>
Executing the command mentioned above will perform the following actions:
- Adds
@angular/service-workeras a dependency to your project. - Enables service worker builds in the Angular CLI.
- Imports and registers the service worker in the application module.
- Updates the
index.htmlfile:- Includes a link to add the manifest.webmanifest file.
- Adds a meta tag for
theme-color.
- Installs icon files to support the installed Progressive Web App (PWA).
- Creates the service worker configuration file called
ngsw-config.json, specifying caching behaviors and other settings.
See Getting started with service workers for more information.
