Local Development Guide

This guide explains how to set up and run applications locally. All apps use a local-first architecture with IndexedDB (Dexie.js) for reads/writes and mana-sync for background synchronization. Server-side compute (AI, file operations, RRULE expansion, etc.) is handled by lightweight Hono/Bun servers.

Quick Start

Fastest: dev:*:local (recommended for daily development)

No auth service needed. Starts mana-sync + server (if any) + web:

pnpm dev:todo:local       # sync + server + web
pnpm dev:chat:local       # sync + server + web
pnpm dev:zitare:local     # sync + web (no server needed)
pnpm dev:clock:local      # sync + web (no server needed)

Guest mode works out of the box -- data lives in IndexedDB, no login required.

Full stack: dev:*:full (with auth + database setup)

Use this when you need authentication, cross-device sync, or to test the full production flow:

pnpm dev:todo:full        # DB setup + auth + sync + server + web
pnpm dev:chat:full        # DB setup + auth + sync + server + web
pnpm dev:zitare:full      # auth + sync + web
pnpm dev:calendar:full    # DB setup + auth + sync + server + web

These commands automatically:

1. Create the database if it doesn't exist (for apps with Drizzle schemas)
2. Push the latest schema (drizzle-kit push --force)
3. Start the auth service (mana-auth)
4. Start mana-sync (Go WebSocket server)
5. Start the Hono/Bun server (if the app has one)
6. Start the web app with colored output

Times	5197	Yes	Yes
Calc	5198	Yes	Yes
ManaVoxel	5028	Yes	Yes

Infrastructure Ports

Service	Port	Description
mana-auth	3001	Central auth (Better Auth + EdDSA JWT)
mana-sync	3050	Data sync (Go, WebSocket, field-level LWW)
PostgreSQL	5432	Database
Redis	6379	Cache
MinIO API	9000	S3-compatible storage
MinIO Console	9001	Storage web UI

Prerequisites

Before running any dev:*:full command:

# 1. Start Docker infrastructure (PostgreSQL, Redis, MinIO)
pnpm docker:up

# 2. Build mana-sync (first time only, or after Go changes)
pnpm dev:sync:build

# 3. Generate environment files (runs automatically on pnpm install)
pnpm setup:env

For dev:*:local, only mana-sync needs to be built. No Docker required unless your server uses a database.

Database Setup Commands

Individual Service Setup

pnpm setup:db:auth        # Setup mana-auth database + schema
pnpm setup:db:chat        # Setup chat database + schema
pnpm setup:db:todo        # Setup todo database + schema
pnpm setup:db:contacts    # Setup contacts database + schema
pnpm setup:db:calendar    # Setup calendar database + schema
pnpm setup:db:picture     # Setup picture database + schema
pnpm setup:db:uload       # Setup uload database + schema
pnpm setup:db:context     # Setup context database + schema
pnpm setup:db:storage     # Setup storage database + schema
pnpm setup:db:mukke       # Setup mukke database + schema
pnpm setup:db:planta      # Setup planta database + schema
pnpm setup:db:nutriphi    # Setup nutriphi database + schema
pnpm setup:db:questions   # Setup questions database + schema
pnpm setup:db:traces      # Setup traces database + schema

Setup All Databases

pnpm setup:db             # Creates ALL databases and pushes ALL schemas

This is useful when setting up a fresh environment or after pulling new schema changes.

How It Works

Architecture

Guest:      App -> IndexedDB (Dexie.js) -> UI              (no sync)
Logged in:  App -> IndexedDB -> UI -> SyncEngine -> mana-sync (Go) -> PostgreSQL
                                    <- WebSocket push <-

mana-sync (Go, port 3050) handles WebSocket-based sync with field-level last-write-wins conflict resolution. All CRUD goes through IndexedDB first, making the UI instant regardless of network.

Hono/Bun servers handle operations that cannot run client-side:

• AI/LLM calls (chat, questions, picture generation)
• File operations (storage, media processing)
• RRULE expansion and reminder scheduling (todo, calendar)
• Server-side data processing (news extraction, transcription)

Docker Init Script

On first pnpm docker:up, the PostgreSQL container runs docker/init-db/01-create-databases.sql which creates all databases.

Setup Script

The scripts/setup-databases.sh script:

1. Creates database if it doesn't exist (using psql)
2. Pushes schema using drizzle-kit push --force

The --force flag auto-approves schema changes without interactive prompts.

What each command starts

Command pattern	What it runs
dev:*:local	mana-sync + server (if any) + web
dev:*:full	DB setup + mana-auth + mana-sync + server (if any) + web
dev:*:server	Just the Hono/Bun server (bun run --watch src/index.ts)
dev:*:web	Just the SvelteKit web app
dev:*:app	Server + web (no sync, no auth)

Troubleshooting

Database doesn't exist

If you see database "xxx" does not exist:

# Option 1: Run the setup script
pnpm setup:db:chat  # or whichever service

# Option 2: Create manually
PGPASSWORD=devpassword psql -h localhost -U manacore -d postgres -c "CREATE DATABASE chat;"

Schema out of date

If you see errors about missing tables/columns:

# Push the latest schema from the server package
pnpm --filter @chat/server db:push --force

mana-sync not built

If you see ./server: No such file or directory:

pnpm dev:sync:build

Port already in use

If auth (port 3001) or sync (port 3050) is already running:

# Check what's using the port
lsof -i :3001
lsof -i :3050

# Kill the process if needed
kill <PID>

Fresh Start (Nuclear Option)

To completely reset all databases:

# Stop and remove all containers + volumes
pnpm docker:clean

# Start fresh
pnpm docker:up

# Setup all databases
pnpm setup:db

Adding a New Application

Step 1: Create Project Structure

Create the standard project structure under apps/:

apps/newproject/
├── apps/
│   ├── server/       # Hono/Bun server (if needed for compute)
│   ├── mobile/       # Expo React Native app
│   ├── web/          # SvelteKit web app
│   └── landing/      # Astro marketing page
├── packages/         # Project-specific shared code
├── package.json      # Workspace root
├── pnpm-workspace.yaml
└── CLAUDE.md         # Project documentation

Step 2: Set Up Local-First Data Layer

1. Create apps/newproject/apps/web/src/lib/data/local-store.ts with createLocalStore()
2. Create apps/newproject/apps/web/src/lib/data/guest-seed.ts for onboarding data
3. Use collection.getAll() / collection.insert() in stores (not API calls)
4. In layout: await store.initialize(), store.startSync() on login

Step 3: Create Hono/Bun Server (if needed)

Only needed if your app requires server-side compute (AI, file ops, etc.).

Create apps/newproject/apps/server/ with:

• src/index.ts -- Hono app entry point
• src/config.ts -- Port and env config
• src/routes/health.ts -- Health check endpoint
• package.json with "name": "@newproject/server"

Step 4: Configure Database (if the server uses Drizzle)

1. Add database to Docker init (docker/init-db/01-create-databases.sql):

   CREATE DATABASE IF NOT EXISTS newproject;
   GRANT ALL PRIVILEGES ON DATABASE newproject TO manacore;
   

2. Add to setup script (scripts/setup-databases.sh):

   newproject)
       create_db_if_not_exists "newproject"
       push_schema "@newproject/server" "newproject"
       ;;
   

3. Add DATABASE_URL to .env.development:

   NEWPROJECT_DATABASE_URL=postgresql://manacore:devpassword@localhost:5432/newproject
   

4. Update scripts/generate-env.mjs to generate the server .env file.

Step 5: Add Package.json Scripts

Add to root package.json:

{
  "scripts": {
    "dev:newproject:web": "pnpm --filter @newproject/web dev",
    "dev:newproject:server": "cd apps/newproject/apps/server && bun run --watch src/index.ts",
    "dev:newproject:local": "concurrently -n sync,server,web -c magenta,yellow,cyan \"pnpm dev:sync\" \"pnpm dev:newproject:server\" \"pnpm dev:newproject:web\"",
    "dev:newproject:full": "./scripts/setup-databases.sh newproject && ./scripts/setup-databases.sh auth && concurrently -n auth,sync,server,web -c blue,magenta,yellow,cyan \"pnpm dev:auth\" \"pnpm dev:sync\" \"pnpm dev:newproject:server\" \"pnpm dev:newproject:web\"",
    "setup:db:newproject": "./scripts/setup-databases.sh newproject"
  }
}

For apps without a server (sync + web only):

{
  "scripts": {
    "dev:newproject:web": "pnpm --filter @newproject/web dev",
    "dev:newproject:local": "concurrently -n sync,web -c magenta,cyan \"pnpm dev:sync\" \"pnpm dev:newproject:web\"",
    "dev:newproject:full": "concurrently -n auth,sync,web -c blue,magenta,cyan \"pnpm dev:auth\" \"pnpm dev:sync\" \"pnpm dev:newproject:web\""
  }
}

Step 6: Create Project CLAUDE.md

Create apps/newproject/CLAUDE.md with project overview, structure, commands, and API endpoints.

Step 7: Test the Setup

# Quick start (no auth needed)
pnpm dev:newproject:local

# Full stack (with auth + DB setup)
pnpm dev:newproject:full
