pm2-ecosystem
Type-safe PM2 configurations without the pm2
package - quick start
Justification
PM2 does provide TypeScript types out-of-the box.
module.exports = {
/** @type {import('pm2').StartOptions[]} */
apps: [{ name: 'app', script: './app.js' }],
};
However, pm2
is not meant to be installed locally.
# Reference https://pm2.keymetrics.io/docs/usage/quick-start/
npm install pm2@latest -g
yarn global add pm2
Since there is no @types/pm2
package, use this instead.
Quick Start
npm i pm2-ecosystem -D
pnpm i pm2-ecosystem -D
// Method 1: Using the `defineApp` function
const { defineApp } = require('pm2-ecosystem');
module.exports = {
apps: [
defineApp({ name: 'app1', script: './app1.js' }),
defineApp({ name: 'app2', script: './app2.js' }),
// ...
],
};
// Method 2: Using JSDoc
module.exports = {
/** @type {import('pm2-ecosystem').StartOptions[]} */
apps: [
{ name: 'app1', script: './app1.js' },
{ name: 'app2', script: './app2.js' },
],
};
ECMAScript Modules
In a ESM project, the JavaScript configuration file must have the .cjs
extension.
| Example Filename | package.json
|
| ---------------------- | -------------------- |
| ecosystem.config.js
| "type": "commonjs"
|
| ecosystem.config.cjs
| "type": "module"
|
# If the filename is `ecosystem.config.js`
pm2 start # the filename can be omitted.
pm2 start ecosystem.config.js
# If not, the filename must be specified.
pm2 start ecosystem.config.cjs
pm2 start pm2.config.cjs
