在 Windows 上运行并行 npm 脚本

Question

I have an npm parallel script in my package.json that works on a mac but not on windows:

"myScript": "nodemon ./server.js & cross-env NODE_ENV=development webpack-dev-server"

When it is separated into two scripts to run separately, it works fine on both mac and windows:

"myScript1": "cross-env NODE_ENV=development webpack-dev-server",
"myScript2": "nodemon ./server.js",

I would like to keep the parallel script so that I don't have to run both separately. How do I make this work on windows?

Answer 1

I have a workaround for this, using module concurrently . So you script section would look something like this:

scripts: {
  "myScript": "concurrently \"npm run myScript1\" \"npm run myScript2\"",
  "myScript1": "cross-env NODE_ENV=development webpack-dev-server",
  "myScript2": "nodemon ./server.js",
}

Answer 2

I recommend using npm-run-all I think the syntax is a bit cleaner:

scripts: {
  "myScript": "run-p myScript1 myScript2",
  "myScript1": "cross-env NODE_ENV=development webpack-dev-server",
  "myScript2": "nodemon ./server.js",
}

This npm-run-all package provides 3 CLI commands.

• npm-run-all
• run-s
• run-p

The main command is npm-run-all. We can make complex plans with npm-run-all command.

Both run-s and run-p are shorthand commands.
run-s is for sequential, run-p is for parallel. We can make simple plans with those commands.
