How to set service worker with webpack encore?

To set up a service worker with webpack encore, you first need to create a service worker file in your project directory. This file will contain the code for your service worker, which will be responsible for caching your files and resources to improve performance.

Once you have created your service worker file, you can configure webpack encore to include it in your project.

To do this, you can use the addEntry() method in your webpack.config.js file to specify the path to your service worker file as an entry point. For example:

1
2
3
4
5

Encore
    // your other webpack encore configuration options
    .addEntry('service-worker', './path/to/your/service-worker.js')
    // your other webpack encore configuration options
;

Next, you can add the CopyWebpackPlugin plugin to copy your service worker file to the output directory. This will ensure that your service worker is included in the build output. You can do this by adding the following code to your webpack.config.js file:

1
2
3
4
5
6
7
8
9

const CopyWebpackPlugin = require('copy-webpack-plugin');

Encore
    // your other webpack encore configuration options
    .addPlugin(new CopyWebpackPlugin([
        { from: './path/to/your/service-worker.js', to: 'service-worker.js' }
    ]))
    // your other webpack encore configuration options
;

Finally, run webpack encore to build your project with the service worker included:

1

yarn encore production

Your service worker should now be set up and included in your project build. You can test it by registering the service worker in your application code and checking that it is caching your files and resources as expected.
