Node.js 应用程序 - 由 NPM 启动时不同的 NODE_ENV

Question

I have a node.js app. It runs in the "production" mode when it was launched by the npm start and in the 'development' mode when it was launched by node start.js . I don't understand the difference.

How can I set the 'development' mode according the system variable also for the 'npm start'?

Inside the script I log the value of the NODE_ENV this way:

console.log(process.env.NODE_ENV)

My system variable:

d:\>echo %NODE_ENV%
development

My NPN content:

...
"private": true,
"main": "start.js",
"scripts": {
  "start": "node --use_strict start.js",
...

The problem:

• when I run node --use_strict start.js - returns: "development" (right)
• when I run npm start - returns production (wrong)

(win: 7, npm: 3.8.3, node: v5.10.1)

Answer 1

The solution:

npm config set production=false

The NPM provides own config register.
