@dawnjs/dn-middleware-webpack

Getting Started

To begin, you'll need to install @dawnjs/dn-middleware-webpack:

$ npm i -D @dawnjs/dn-middleware-webpack

Then add the middleware to your dawn pipeline configuration. For example:

.dawn/pipe.yml

dev:
  - name: '@dawnjs/dn-middleware-webpack'

And run dn dev via your preferred method.

Important Warning

To be sure no other webpack middleware installed in your project. If any, please install the latest webpack@5 with npm install --dev webpack@5 manually in your project to ensure node_modules/webpack's version is 5.x.

configFile

Type: string
Default: "./webpack.config.js"

By default, the custom configration file must export a valid function.
In compatible mode, the custom configration file could export a valid function or a valid webpack config object.

Important: It is not recommend to modify existing module rules because their structure might be changed in the future.

Examples:

module.exports = function (config, webpack, ctx) {
  // config: a webpack config object or an instance of webpack-chain's `Config` in chainable mode
  // webpack: the imported `webpack` function
  // ctx: the dawn context
};

chainable

Type: boolean
Default: false

By default, the first argument of custom configration function is a webpack config object.
If enable chainable mode, the first argument would be a webpack-chain's Config instance.
