Allows exporting a JSON file that maps chunk ids to their resulting asset files. Webpack can then read this mapping, assuming it is provided somehow on the client, instead of storing a mapping (with chunk asset hashes) in the bootstrap script, which allows to actually leverage long-term caching.
Install via npm:
npm install chunk-manifest-webpack-plugin
And then require and provide to webpack:
// in webpack.config.js or similar
var ChunkManifestPlugin = require('chunk-manifest-webpack-plugin');
module.exports = {
// your config values here
plugins: [
new ChunkManifestPlugin({
filename: "manifest.json",
manifestVariable: "webpackManifest"
})
]
};
Where the manifest will be exported to on bundle compilation. This will be relative to the main webpack output directory. Default = "manifest.json"
What JS variable on the client webpack should refer to when requiring chunks. Default = "webpackManifest"
