Access the current environment variables with `process.env` or `Bun.env`.
|
||
|
|
|
||
|
|
```ts index.ts icon="/icons/typescript.svg"
|
||
|
|
Bun.env.API_TOKEN; // => "secret"
|
||
|
|
process.env.API_TOKEN; // => "secret"
|
||
|
|
```
|
||
|
|
|
||
|

|
||
|
|
|
||
|
|
Set these variables in a `.env` file.
|
||
|
|
|
||
|
|
Bun reads the following files automatically (listed in order of increasing precedence).
|
||
|
|
|
||
|
|
- `.env`
|
||
|
|
- `.env.production`, `.env.development`, `.env.test` (depending on value of `NODE_ENV`)
|
||
|
|
- `.env.local` (not loaded when `NODE_ENV=test`)
|
||
|
|
- `.env.production.local`, `.env.development.local`, `.env.test.local` (depending on value of `NODE_ENV`)
|
||
|
|
|
||
|
|
```ini .env icon="settings"
|
||
|
|
FOO=hello
|
||
|
|
BAR=world
|
||
|
|
```
