react获取运行环境是开发还是生产环境。

import getConfig from '../../../../env.js' // 接口前缀
let phoneApi; // 接口地址获取
if (process.env.NODE_ENV == "development") {
    phoneApi = getConfig.development.PHONE_API;

} else {
    phoneApi = getConfig.production.PHONE_API;
}

module.exports = {
  development: {

    PHONE_API: 'http://192.....:3210',
    PORT: 3000,
    VERSION: '0.0.1',
    MODE: 'development',
    NODE_ENV: 'production'
  },
  production: {

    PHONE_API: 'http://........com',
    PORT: 3000,
    VERSION: '0.0.1',
    MODE: 'production',
    NODE_ENV: 'production'
  }
}
