# Super simple API-based stock terminal
|
||||
|
||||
Run the backend with
|
||||
|
||||
```bash
|
||||
uvicorn dengfun.retail.api.main:app
|
||||
```
|
||||
|
||||
Use Caddy to reverse proxy and the following Caddyfile. Paths are static so you have to run caddy from the root of the package
|
||||
|
||||
```
|
||||
:80 {
|
||||
handle_path /api/v1/* {
|
||||
reverse_proxy localhost:8000
|
||||
}
|
||||
file_server {
|
||||
root src/dengfun/retail/api/static
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
If you execute
|
||||
|
||||
```bash
|
||||
caddy run -c Caddyfile
|
||||
```
|
||||
|
||||
You should be able to browse the application at http://127.0.0.1, and reach the api docs at http://127.0.0.1/api/v1/docs
|
||||
|
||||
Caddy can be installed in Windows with Chocolatey
