Despite the number of modules in this package, there are a number of approaches to using these tools which many be used separately or together in any number of combinations.
- Precaching, runtime caching and routing: Use sw-lib to quickly implement caching strategies or a route.
- Build process: Generate a service worker or manifest in your build process using sw-build.
- Command line: Generate a service worker or manifest from the command line.
- Go beyond the basics: Implement more advanced capabilities and more sophisticated use cases using any of the other libraries, which are described below.
Each module is installed separately using the command line as listed below. To use a particular module:
-
Install the module. For example:
npm install --save-dev sw-lib
-
Copy the module's JavaScript and map files to your serving directory.
cp node_modules/sw-lib/build/* app/
-
Import the modules to your service worker file. For example:
importScripts('sw-lib.min.js');
All of the modules are described below. Each has an About page with basic usage instructions and a Demo directory with an example. The main page of the documentation is here.
