open-gsio

Stack:

• vike
• react
• cloudflare workers
• itty-router
• mobx-state-tree
• openai sdk

Quickstart

1. bun i
2. Add your own GROQ_API_KEY in .dev.vars
3. 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

Testing

The project uses Vitest for testing frontend components and hooks. Tests are located in __tests__ directories next to the code they test.

To run tests:

• bun run test - Run all tests once
• bun run test:watch - Run tests in watch mode
• bun run test:coverage - Run tests with coverage report

Deploying

1. Setup the KV_STORAGE bindings in wrangler.jsonc
2. Add another GROQ_API_KEY in secrets.json
3. Run bun run deploy && bun run deploy:secrets && bun run deploy

Note: Subsequent deployments should omit bun run deploy:secrets

Local Inference (Apple Silicon Only)

##### 
# install mlx-omni-server (custom homebrew wrapper)
brew tap seemueller-io/tap
brew install seemueller-io/tap/mlx-omni-server
#####
# Run mlx-omni-server
bun run openai:local
####
# Override OPENAI_* variables in .dev.vars
sed -i '' '/^OPENAI_API_KEY=/d' .dev.vars; echo 'OPENAI_API_KEY=not-needed' >> .dev.vars
sed -i '' '/^OPENAI_API_ENDPOINT=/d' .dev.vars; echo 'OPENAI_API_ENDPOINT=http://localhost:10240' >> .dev.vars
### Restart open-gsio server so it uses the new variables
bun run server:dev
