name: Add a development dependency
---
To add an npm package as a development dependency, use `bun add --development`.
```sh
$ bun add zod --dev
$ bun add zod -d # shorthand
```
---
This will add the package to `devDependencies` in `package.json`.
```json-diff
{
"devDependencies": {
+ "zod": "^3.0.0"
}
}
```
---
See [Docs > Package manager](/docs/cli/install) for complete documentation of Bun's package manager.
