name: Set environment variables
|
|
---
|
|
|
|
The current environment variables can be accessed via `process.env` or `Bun.env`.
|
|
|
|
```ts
|
|
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` or `.env.development` (depending on value of `NODE_ENV`)
|
|
- `.env.local`
|
|
|
|
```txt#.env
|
|
FOO=hello
|
|
BAR=world
|
|
```
|
|
|
|
---
|
|
|
|
Variables can also be set via the command line.
|
|
|
|
```sh
|
|
$ FOO=helloworld bun run dev
|
|
```
