# now-deno
> Deno builder for Vercel - run Deno on `vercel`. 🦕 + λ = ❤️
This builder allows you to run [Deno](https://deno.land) as a lambda on `vercel`.
## Usage
If you're unfamiliar with `vercel` runtimes, please read the [runtime docs](https://vercel.com/docs/runtimes) first. This runtime can be used like any other Community Runtime.
```json
// vercel.json
{
"functions": {
"api/**/*.{j,t}s": {
"runtime": "[email protected]"
}
}
}
```
Note: You need `vercel` v17.x or above to use the above configuration.
```ts
// api/hello.ts
import {
APIGatewayProxyEvent,
APIGatewayProxyResult,
Context,
} from 'https://deno.land/x/lambda/mod.ts';
export async function handler(
event: APIGatewayProxyEvent,
context: Context
): Promise {
return {
statusCode: 200,
body: `Welcome to deno ${Deno.version.deno} 🦕`,
headers: {
'content-type': 'text/html; charset=utf-8',
},
};
}
```
That's the simplest way to use this runtime!
## Advanced usage
### Specific Deno version
To use a specific version of Deno you can specify a environment variable in your `vercel.json`:
```json
// vercel.json
{
"functions": {
...
},
"env": {
"DENO_VERSION": "0.42.0"
}
}
```
### Unstable mode
To use Deno's `unstable` mode you can specify the environment variable `DENO_UNSTABLE` in your `vercel.json`:
```json
// vercel.json
{
"functions": {
...
},
"env": {
"DENO_UNSTABLE": "true"
}
}
```
### TS Config
To pass a custom config, you can specify the variable `DENO_CONFIG` in your `now.json`:
```json
// now.json
{
"functions": {
...
},
"env": {
"DENO_CONFIG": "tsconfig.json"
}
}
```
### Custom pre-package script
You can place a `build.sh` function in the root of your deploy directory. This will be executed before the function is packaged up.
## `vercel dev`
> **`vercel dev` is currently only supported on macOS and Linux. It is not supported on Windows.**
If you have have `deno` installed in your path then you can use `vercel dev` with this runtime. It should work just like any other runtime.

This was only possible due to the great work of [Andy Hayden](https://github.com/hayd) who made the first attempts at running [deno in a lambda function](https://github.com/hayd/deno-lambda).
