• Installation
• Architecture
• Roadmap
• Deployment

• Node: Check node with node -v. Install Node 20.x or 22.x with (recommended) Volta.
• Docker: Install Orbstack or Docker

git clone [email protected]:cellajs/cella.git && cd cella

Create a .env in /env folder. Recommended defaults are in .env.example. Then install:

pnpm install

Make sure docker runs in the background with a postgres db in it.

pnpm run docker

Cella adopted a local-first strategy, whereby page-related resources are handled normally by an API, whereas content-related resources are fully handled local-first using ElectricSQL. Therefore, generate and migrate commands will execute both for normal schemas and for electric schemas in /backend.

pnpm run generate
pnpm run migrate 

Generate local-first sync layer in /frontend with ElectricSQL

pnpm run electrify

Check it out at localhost:3000

pnpm run dev

The user seed is required to add an ADMIN user. Check /backend/seed to add more data with faker.js.

pnpm run seed:user
pnpm run seed:organizations

Use Drizzle Studio to manage your local db on local.drizzle.studio

pnpm run studio

Cella uses Scalar for autogenerated OpenAPI docs. Docs refresh on changes at localhost:4000/docs

• Please install Biome for code style. Fix with pnpm run check:fix and type check with pnpm run check:types
• EADDRINUSE errors? Try sudo lsof -i :1080 -i :3000 -i :4000 and then kill -9 *PID* with a space-separated list of PID
• pnpm cache issues? Try pnpm store prune
• turbo cache issues? Try adding --force to the command
• docker cache issues? Try docker builder prune --force
