Generates an appcache manifest with custom cache, network, fallback, exclude patterns, and output filename.

const HtmlWebpackPlugin = require('html-webpack-plugin'); const AppCachePlugin = require('appcache-webpack-plugin'); module.exports = { entry: './app.js', output: { path: './dist', filename: 'bundle.js' }, plugins: [ new HtmlWebpackPlugin(), new AppCachePlugin({ cache: ['image.jpg'], network: ['*'], fallback: ['fallback.html'], settings: ['prefer-online'], exclude: ['file.txt', /.*\.js$/], output: 'my-app.appcache' }) ] };
Debug
Known issues
deprecatedHTML5 Application Cache (AppCache) is deprecated and removed from modern browsers. Use Service Workers instead.
fix
Migrate to a service worker plugin like workbox-webpack-plugin.
affects: >=1.0.0
gotchaThe plugin outputs an .appcache file but does not update the HTML <html> manifest attribute automatically. You must do that manually or via another plugin.
fix
Add manifest='my-manifest.appcache' to the <html> tag in your HTML template.
affects: >=1.0.0
gotchaIf `network` option is not set, it defaults to ['*']; if you set it to null or an empty array, no network access is allowed.
fix
Explicitly set `network: ['*']` or `network: null` based on desired behavior.
affects: >=1.0.0
breakingWebpack 5 is not supported; this plugin only works with webpack <=4.x.x.
fix
Use an alternative plugin like serviceworker-webpack-plugin or workbox-webpack-plugin.
affects: >=1.0.0 <=1.4.0
gotchaExclude patterns: if you exclude .js files via /.*\.js$/, the bundle itself (a .js file) will be excluded from the manifest, which may not be intended.
fix
Double-check exclude patterns to ensure critical assets are not omitted.
affects: >=1.0.0
