在“npm run”调用上设置 Node.js 环境变量

Question

package.json

{
  "scripts": {
    "start": "NODE_ENV=development node ./index.js"
  }
}

Is it possible, for example, to pass and override NODE_ENV on npm run start ?

npm run start NODE_ENV=production

Answer 1

Why not just add one more script

{
  "scripts": {
    "start": "NODE_ENV=development node ./index.js",
    "production": "NODE_ENV=production node ./index.js"
  }
}

And then run

npm run production
