<p align="center">
  Check that the critical environment variables are set for your app,
  and that you did not leave dangerous development overrides in production.
</p>

## Installation

```
yarn add @47ng/check-env
```

## Usage

```js
import { checkEnv } from '@47ng/check-env'

checkEnv({
  // Will log an error and throw if any of these are missing:
  required: [
    'SOME_API_SECRET',
    'PRIVATE_TOKEN',
    'SOME_OTHER_IMPORTANT_THING'
    // ...
  ],

// Will log an error and throw if any of these are set in production:
  unsafe: [
    'LOCAL_OVERRIDE_DISABLE_HTTPS',
    'INSECURE_COOKIES'
    // ...
  ]
})
```

If some required environment variable are not set, it will tell you and throw
an error at the end:
!["CLI output"](https://raw.githubusercontent.com/47ng/check-env/next/output.png)

## Error handling

You can choose to skip throwing an error with the `noThrow` option:

```js
checkEnv({
  noThrow: true,
  ...
})
```

## Conditional Checks

If you want to require some variables only in production, you can add a condition
before the variable name, any falsy value will be ignored:

```ts
const __PROD__ = process.env.NODE_ENV === 'production'

checkEnv({
  required: [
    'ALWAYS_REQUIRED',
    __PROD__ && 'ONLY_REQUIRED_IN_PRODUCTION',
    !__PROD__ && 'YOU_GET_THE_IDEA'
  ]
})
```

## Logging

By default, `check-env` uses `console.err` with emoji.

You can override the default logging methods with `logMissing` and `logUnsafe`.

Example using [Pino](https://github.com/pinojs/pino):

```js
const logger = require('pino')()

checkEnv({
  logMissing: name => logger.error(`Missing required environment variable ${name}`),
  logUnsafe: name => logger.warn(`Unsafe environment variable ${name} set in production`),
  ...
})
```
