# Bun Runtime for AWS Lambda
This repository provides [Bun](https://bun.sh/) as an AWS Lambda runtime layer. It enables running JavaScript and TypeScript applications on AWS Lambda using Bun.
> [!TIP]
> This is Bun itself packaged as a Lambda layer, not the special Lambda runtime layer that Bun provides. If you need that layer, you can find instructions over at [oven-sh/bun/packages/bun-lambda](https://github.com/oven-sh/bun/tree/main/packages/bun-lambda)
## Available Layers
Two architecture layers are available:
| Layer Name | Arch | ARN |
|-----------------|-------|-----------------------------------------------------------------|
| BunRuntimeArm64 | ARM64 | `arn:aws:lambda:{region}:582637575117:layer:BunRuntimeArm64:{version}` |
| BunRuntimeX64 | X64 | `arn:aws:lambda:{region}:582637575117:layer:BunRuntimeX64:{version}` |
## Automatic Updates
[Check Bun Version](https://github.com/sumcoding/bun-runtime/actions/workflows/check-bun-version.yml)
This repository automatically checks for new Bun releases on the first day of each month. When a new version is detected:
1. GitHub Actions builds the new layer packages
2. Deploys them to AWS regions as a new version
> [!NOTE]
> The version of Bun in the layer may be behind the version in the bun repo and there will not be a corresponding layer version for every version of bun released.
