webpack-manifest-extra-plugin


#### manifest.json generator can be used not only include all emitted assets but also in multiply compilation cases

$3

webpack-manifest-plugin is fine? why another manifest-plugin?

* can not used in multiply compilation cases, use 'seed' option sometimes it will get wrong file format
* if you include another plugin that just emit file in webpack compilation, the manifest.json will not find it

$3

after every emit and done,this plugin will find the manifest.json in dist folder,if already has,it will merge old manifest and new manifest to a final file,and you can modify it just by transform function

install

``shell
yarn add webpack-manifest-extra-plugin -D


or


npm install webpack-manifest-extra-plugin -D
`

use

`js
// webpack.config.js
const WebpackManifestExtraPlugin = require('webpack-manifest-extra-plugin')
{
//...
plugins:[
new WebpackManifestExtraPlugin({
filename:'manifest.json' // default -> manifest.json,
verbose: true // default -> true,
publicPath:'/' // default -> webpack's publicPath config
transform(manifest){ // manifest.json object && webpack's statsJson object
// ... your transforms
return manifest // return
}
})
]
//...
}
`

use in multiply compilation
in this example two compilation are all use the default same filename 'manifest.json', so plugin will merge it to one final file
`js
// webpack.config.js
[
// first
{
// ...
plugins: [new WebpackManifestExtraPlugin()]
// ...
},
// second
{
//...
plugins: [new WebpackManifestExtraPlugin()]
//...
}
]
