How can I run multiple npm scripts at the same time?

Question

In my package.json, I defined two scripts. How do I run them at the same time?

"scripts": {
    "server": "webpack-dev-server",
    "webpack": "webpack -wd",
},

Answer 1

Invoke scripts via npm run with & for parallel execution or with && for sequential execution:

npm run server & npm run webpack

Explanation:

Use &&  for sequential execution.
Use &  for parallel execution.

Answer 2

"scripts": {
    "sw": "webpack-dev-server & webpack -wd"
},

then

npm run sw
