run-script-webpack-plugin
Automatically run your script once Webpack's build completes.
NOTE: mostly copied from this repo, but strongly typed from scratch
Installation
$ npm i -D run-script-webpack-plugin
Usage
In webpack.config.js
:
import { RunScriptWebpackPlugin } from "run-script-webpack-plugin";
export default {
plugins: [
...
// Only use this in DEVELOPMENT
new RunScriptWebpackPlugin({
name: 'server.js',
nodeArgs: ['--inspect'], // allow debugging
args: ['scriptArgument1', 'scriptArgument2'], // pass args to script
signal: false | true | 'SIGUSR2', // signal to send for HMR (defaults to `false`, uses 'SIGUSR2' if `true`)
keyboard: true | false, // Allow typing 'rs' to restart the server. default: only if NODE_ENV is 'development'
cwd: undefined | string, // set a current working directory for the child process default: current cwd
}),
],
}
The name
argument in RunScriptWebpackPluginOptions
refers to the built asset, which is named by the output options of webpack (in the example the entry server
becomes server.js
. This way, the plugin knows which entry to start in case there are several.
If you don't pass a name, the plugin will tell you the available names.
You can use nodeArgs
and args
to pass arguments to node and your script, respectively. For example, you can use this to use the node debugger.
To use Hot Module Reloading with your server code, set Webpack to "hot" mode and include the webpack/hot/poll
or webpack/hot/signal
modules. Make sure they are part of your server bundle, e.g. if you are using node-externals
put them in your whitelist. The latter module requires the signal
option.
