Progressive Web App manifest loader for webpack, which will load referenced images files.
If you want to write your own PWA manifest, include it in a html file that's in your build, and have webpack process the image assets from the manifest then this is the loader for you.
This loader is typically used in combination with html-loader, (either as part of a html template for HtmlWebpackPlugin or as a html file processed directly by html-loader and exported as a static HTML file). The loader outputs JSON source as a string including transformed icon src URLs.
npm i --save-dev pwa-manifest-loader
Configure webpack to use the loader by adding a rule to your config:
webpack.config.js
module.exports = {
module: {
rules: [
{
// use pwa-manifest-loader for manifest.json, or app.webmanifest so icons get loaded
test: /manifest.json$\|.webmanifest$/,
use: 'pwa-manifest-loader'
},
// ... other loaders etc
],
// ...
}
}
In any html file processed by html-loader:
includes/head.html
<link rel="manifest" href="./manifest.json" />
The manifest path should be relative to the html file that includes it. html-loader will replace it with the correct output path in the generated HTML.
manifest.json / app.webmanifest
{
"name": "MyApp",
"short_name": "MyApp",
"description": "App description etc.",
"start_url": "/",
"theme_color": "#ffffff",
"background_color": "#ffffff",
"display": "standalone",
"icons": [
{
"src": "./img/icon-32.png",
"sizes": "32x32"
},
{
"src": "./img/icon-64.png",
"sizes": "64x64"
},
{
"src": "./img/icon-180.png",
"sizes": "180x180"
},
{
"src": "./img/icon.svg",
"sizes": "any",
"purpose": "any"
},
{
"src": "./img/icon-maskable.svg",
"sizes": "any",
"purpose": "maskable"
}
]
}
All of the referenced icons will be loaded by your webpack loaders. For
example, if you're using
ImageMinimizerWebpackPlugin
you can use ?as=webp&w=180&h=180
on an icon src URL to compile it as a
specific format and size.
