The recommended way to detect when code is being executed with Bun is to check `process.versions.bun`. This works in both JavaScript and TypeScript without requiring any additional type definitions.
|
|
|
|
```ts
|
|
if (process.versions.bun) {
|
|
// this code will only run when the file is run with Bun
|
|
}
|
|
```
|
|
|

Alternatively, you can check for the existence of the `Bun` global. This is similar to how you'd check for the existence of the `window` variable to detect when code is being executed in a browser.
|
|
|
|
<Note>
|
|
This approach will result in a type error in TypeScript unless `@types/bun` is installed. You can install it with `bun
|
|
add -d @types/bun`.
|
|
</Note>
|
|
|
|
```ts
|
|
if (typeof Bun !== "undefined") {
|
|
// this code will only run when the file is run with Bun
|
|
}
|
|
```
