## Installation

1. `bun i && bun test`
1. [Add your own `GROQ_API_KEY` in .dev.vars](https://console.groq.com/keys)  
1. In isolated shells, run `bun run server:dev` and `bun run client:dev`

> Note: it should be possible to use pnpm in place of bun. 

## Deployment
1. Setup the KV_STORAGE bindings in `wrangler.jsonc`  
1.  [Add another `GROQ_API_KEY` in secrets.json](https://console.groq.com/keys)
1. Run `bun run deploy && bun run deploy:secrets && bun run deploy`

> Note: Subsequent deployments should omit `bun run deploy:secrets`


## Local Inference
> Local inference is achieved by overriding the `OPENAI_API_KEY` and `OPENAI_API_ENDPOINT` environment variables. See below.
### Ollama
~~~bash
docker run -d -v ollama:/root/.ollama -p 11434:11434 --name ollama ollama/ollama ## Run Ollama (Can also be installed natively)
bun run openai:local                         # Start OpenAI-compatible server
sed -i '' '/^OPENAI_API_KEY=/d' .dev.vars; echo >> .dev.vars; echo 'OPENAI_API_KEY=required-but-not-used' >> .dev.vars # Reset API key
sed -i '' '/^OPENAI_API_ENDPOINT=/d' .dev.vars; echo >> .dev.vars; echo 'OPENAI_API_ENDPOINT=http://localhost:11434' >> .dev.vars # Reset endpoint
bun run server:dev                           # Start dev server
~~~

### mlx-omni-server (Apple Silicon Only)
~~~bash
brew tap seemueller-io/tap                   # Add seemueller-io tap
brew install seemueller-io/tap/mlx-omni-server # Install mlx-omni-server
bun run openai:local                         # Start OpenAI-compatible server
sed -i '' '/^OPENAI_API_KEY=/d' .dev.vars; echo >> .dev.vars; echo 'OPENAI_API_KEY=required-but-not-used' >> .dev.vars # Reset API key
sed -i '' '/^OPENAI_API_ENDPOINT=/d' .dev.vars; echo >> .dev.vars; echo 'OPENAI_API_ENDPOINT=http://localhost:10240' >> .dev.vars # Reset endpoint
bun run server:dev                           # Start dev server
~~~
#### Adding models for local inference (Apple Silicon)

~~~bash
# ensure mlx-omni-server is running in the background 
MODEL_TO_ADD=mlx-community/gemma-3-4b-it-8bit

curl http://localhost:10240/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d "{
    \"model\": \"$MODEL_TO_ADD\",
    \"messages\": [{\"role\": \"user\", \"content\": \"Hello\"}]
  }"
~~~  




## Testing

Tests are located in `__tests__` directories next to the code they test. Testing is incomplete at this time.

> `bun run test` will run all tests
