A flexible Babel plugin that loads environment variables for multiple environments
npm install @elselabs/babel-env
npm i @elselabs/babel-env
Add to the plugins list inside .babelrc or babel.config.js, depending on which config used by your project. (Babel configuration docs link)
`
// .babelrc
{
"plugins": ["module:@elselabs/babel-env"]
}// babel.config.js
module.exports = {
plugins: ['module:@elselabs/babel-env'],
}
NOTE: Older versions of babel (< 7) do not require the prefix.Usage
By default this package reads a .env file inside the project root folder.
`
API_KEY=ipsum
And allows you to import these variables in your JS.
import { API_KEY } from '@elselabs/babel-env';
console.log(API_KEY)// or
import config from '@elselabs/babel-env';
console.log(config.API_KEY)

By default this package reads the environment variable to determine which .env to read. Therefore, if you set export BABEL_ENV=production, it will look for a file named .env.production.The environment variable, file format, file directory and import module name are all configurable.

-
environmentVariable - By default uses the BABEL_ENV environment variable. You may want to override the environment variable used to determine which environment your compiling. In some cases like
react-native-cli, it uses BABEL_ENV and sets it to either development or production. As a result, its difficult to compile for another environments like staging, test, etc. Alternatively, you can create a custom environment variable and have it use that instead.-
moduleName - By default the import name is @elselabs/babel-env.
- directory - By default uses the root project folder.
- fileFormat - By default uses .env.`
// .babelrc example
{
"plugins": [
["module:@elselabs/babel-env",
{
"environmentVariable": "",
"moduleName": "",
"directory": "",
"fileFormat": ""
}
]
]
}// babel.config.js example
module.exports = {
plugins: [
[
'module:@elselabs/babel-env',
{environmentVariable: '', moduleName: '', fileFormat: '', directory: ''},
],
],
};
