Config Importer

​ Developers can manage environment variables in various stages, such as production, test, development, etc. Developers can set default status by option or NODE_ENV. if you not set default status, it will be development Environment variables are created in the common.js and yourEnvironmentStatus.js However, if an environment variable is declared in an .env file or a system environment variable, that value takes precedence.

How to use

constconfigImporter=require('@araxsiyual/config-importer');constconfig=configImporter.import(__dirname,/*option*/);

Option

{"env";: process.env.NODE_ENV||"development","valueName";: "valueName","default";: "common"}

• env: Environment status, it will read env.js file, and make config
• valueName: If object have valueName, module use valueName's value for read System value or .env, If the object does not have a valueName, module use object name for read System value or .env
• default: default environment file name

Example
