+# @rollup/plugin-run
+
+🍣 A Rollup plugin which runs your bundles in Node once they're built.
+
+Using this plugin gives much faster results compared to what you would do with [nodemon](https://nodemon.io/).
+
+## Install
+
+Using npm:
+
+```console
+npm i -D @rollup/plugin-run
+```
+
+## Usage
+
+Create a `rollup.config.js` [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin:
+
+```js
+// rollup.config.js
+import run from "@rollup/plugin-run";
+
+export default {
+  input: "src/index.js",
+  output: {
+    file: "dist/index.js",
+    format: "cjs"
+  },
+  plugins: [run()]
+};
+```
+
+The app is run in a child process using [child_process.fork(...)](https://nodejs.org/api/child_process.html#child_process_child_process_fork_modulepath_args_options). Each time your bundle is rebuilt when the source code changes, this plugin starts the generated file as a child process (after first closing the previous process, if it's not the first run).
+
+Since this feature is intended for development use, you may prefer to only include it when Rollup is being run in watch mode:
+
+```diff
+// rollup.config.js
+import run from '@rollup/plugin-run';
+
++const dev = process.env.ROLLUP_WATCH === 'true';
+
+export default {
+  input: 'src/index.js',
+  output: {
+    file: 'dist/index.js',
+    format: 'cjs'
+  },
+  plugins: [
+-    run()
++    dev && run()
+  ]
+};
+```
+
+> NOTE: It works with Rollup's code-splitting if you're using dynamic `import(...)` — the only constraint is that you have a single entry point specified in the config.
+
+## Options
+
+You can pass through options such as `env` and `execArgv`. For example, to debug with sourcemaps using [source-map-support](https://www.npmjs.com/package/source-map-support) you could do this:
+
+```diff
+// rollup.config.js
+import run from '@rollup/plugin-run';
+
+export default {
+  input: 'src/index.js',
+  output: {
+    file: 'dist/index.js',
+    format: 'cjs',
++    sourcemap: true
+  },
+  plugins: [
+-    run()
++    run({
++      execArgv: ['-r', 'source-map-support/register']
++    })
+  ]
+};
+```
