Introduce

You may be coding in local, use yourself mysql , mongodb, etc. But in deploy server, the mysql,mongodb's username and password is different. Usually, username and password pass into program through environment. So, this package can auto switch env, if you have a .env file in root of project

Usage

1. npm install env-deploy
2. add a .env file to your project in root path, write env data use json format in it
3. add .env to .gitignore file to ignore it
4. coding, commit, push
5. to deploy server. pull, checkout
6. without .env file to run project

Yeah, you don't to change any code

Example

my project

• project
  • .env
  • index.js
  • .gitignore

.env, now only support json format. allow recursive, join with _

{
    "MONGODB": "localhost",
    "MONGO": {
        "USER": "root",
        "Port": 27017
    }
}

or

# in this format, two kind of comment is supported
# one is prefix line with `#`
// the other is prefix line with `//`
MONGODB = localhost
MONGO_USER = root
MONGO_Port = 27017

in json format, all value would be save as String even if it's a Number. Such as typeof MONGO_PORT return String.

default, all env name will be save as upper case. You can set autoTransformCase as false to turn off this.

index.js - find .env file under __dirname which pass to it. Or it's' default is process.cwd()

require('env-deploy')(__dirname);
console.log(process.env.MONGODB);
console.log(process.env.MONGO_USER);
console.log(process.env.MONGO_PORT);

.gitignore

.env

run with with .env file

localhost
root
27017

in deploy server without .env file, but have environment like MONGODB=111.111.111.111 MONGO_USER=data

111.111.111.111
data
27017

API

env_deploy

• env_deploy([file = process.pwd(),] [config])
  • file {String} filename, relative or absolute path, even directory path contains .env file
  • config {Object}
    • autoTransformCase {Boolean} true to auto transform case to upper, false to disable.

Thanks

thanks for your usage, welcome you to pull request to me.

suggest used in mac os or linux

TODO

[x] support key=value format
