yarn add @nuxtjs/pwa

1. Edit your nuxt.config.js file to add pwa module:

{
    modules: [
        '@nuxtjs/pwa',
    ],
}

sw.*

PWA module is a collection of smaller modules that are designed to magically work out of the box together. To disable each sub-module, you can pass false option with its name as key. For example to disable icon module:

modules: [
    ['@nuxtjs/pwa', { icon: false }],
],

Also each sub-module has its own configuration. Continue reading docs for detailed info.
