# DomainRedirect

This is a simple http redirect service. It is designed to be used with a domain that is not the primary domain for a website. For example, if you have a website at `example.com` and you want to redirect `example.net` to `example.com`, you can use this service.

### Features
- Redirects all requests other than /health to whatever is specified in the `REDIRECT_TARGET` environment variable.
- Health check endpoint at `/health` that returns a 200 status code.

### Limitations
- Paths are not preserved. For example, if a user goes to `example.net/foo`, they will be redirected to the `REDIRECT_TARGET` such as `example.com`.

## Usage

This is not compatible with Node or Deno. It is written to be run with [Bun](https://bun.sh/)

### Run with Bun

```bash
REDIRECT_TARGET="https://example.com/" bun run index.js
```

### Run with Docker

1. Build the image
```bash
docker build -t domainredirect .
```

2. Run the image
```bash
docker run -p 8080:8080 -e REDIRECT_TARGET="https://example.com/" domainredirect
```

> Note: If you are building on Apple Silicon and deploying to x86 like me, you will need to build for a [different platform](https://docs.docker.com/build/architecture/)
