# Redirector

Simple redirection service.
Runs on [Bun](https://bun.sh) and uses [Hono](https://hono.dev).

Can be adapted to run on Node, Cloudflare Workers, or any other serverless platform.

Available as a [Docker image](https://hub.docker.com/r/nzambello/redirector).
Repository: [nzambello/redirector](https://git.nzambello.dev/nzambello/redirector).

## Usage

```sh
yarn install
REDIRECT_URL=https://nzambello.dev PERMANENT=true PRESERVE_PATH=false bun start
```

Then, open http://localhost:8787/ in your browser.

```sh
open http://localhost:8787
```

and you will be redirected to `REDIRECT_URL` from your env.

### Configuration

It loads configuration from environment variables:

- `REDIRECT_URL`: (**required**) the url to redirect to
- `PERMANENT`: if true, it will return a 301 status code, otherwise 302
- `PRESERVE_PATH`: if true, it will preserve the path of the original request

### Docker example

```sh
docker run -p 8787:8787 -e REDIRECT_URL=https://nzambello.dev -e PERMANENT=true -e PRESERVE_PATH=false nzambello/redirector:latest
