About this package

@aurora/cli

Command-line interface for Aurora development - codegen, dev server, and build tools.

Installation

bun add -D @aurora/cli

Commands

aurora codegen

Generate code from schema definitions:

aurora codegen [options]

Options:

  • --force - Force full regeneration (bypass cache)
  • --no-react - Skip React hooks generation
  • --no-zustand - Skip Zustand store generation

Example:

aurora codegen

Generates:

  • TypeScript types
  • Validators (Zod schemas)
  • Repository interfaces
  • API route handlers
  • Client SDK
  • React hooks (optional)
  • Zustand stores (optional)

aurora dev

Start development server with hot reload:

aurora dev [options]

Options:

  • --port <port> - HTTP port (default: 3000)
  • --workers - Start projection workers
  • --watch - Enable watch mode with auto-reload
  • --natsUrl <url> - NATS JetStream URL (default: nats://localhost:4222)
  • --storagePath <path> - Storage directory (default: ./data)

Example:

# HTTP server only
aurora dev

# HTTP server + workers
aurora dev --workers

# With watch mode
aurora dev --watch

# Custom configuration
aurora dev --port 3001 --natsUrl nats://localhost:4222 --storagePath ./data/projections

aurora build

Build application for production:

aurora build

Generates production-ready code and bundles.

aurora check

Validate schemas before code generation:

aurora check

Validates:

  • Event versioning
  • Projection handlers
  • API routes
  • Auth rules
  • Sharding keys

Exit codes:

  • 0 - No errors
  • 1 - Errors found
  • 2 - Warnings only

Example:

aurora check
# Schema validation passed!

aurora admin

Admin commands for sharding and operations:

aurora admin <command> [options]

Commands:

# List all shards
aurora admin shards list

# List shard assignments
aurora admin shards assign

# Rebalance shards
aurora admin shards rebalance

# List nodes
aurora admin nodes list

# Add replica
aurora admin replicas add --shard <shardId> --node <nodeId>

# Remove replica
aurora admin replicas remove --shard <shardId> --node <nodeId>

# Migrate shard
aurora admin migrate --shard <shardId> --from <nodeId> --to <nodeId>

# Failover
aurora admin failover --shard <shardId>

Watch Mode

Watch mode automatically regenerates code and restarts servers on schema changes:

aurora dev --watch

Features:

  • 300ms debouncing
  • Auto-code generation on schema changes
  • Graceful server restart
  • Failed codegen doesn't crash watch process
  • Clean shutdown on SIGINT/SIGTERM

Schema Validation

Pre-commit validation catches errors before runtime:

# Validate schemas
aurora check

# Only proceed if valid
if [ $? -eq 0 ]; then
  aurora codegen
  git add .
  git commit -m "Add new event"
fi

CI/CD Integration

AURORA_STORAGE_PATH ./data Storage directory
NODE_ENV development Environment

Project Structure

Aurora expects this structure:

my-app/
├── schemas/
│   ├── events.schema.ts
│   ├── projections.schema.ts
│   └── api.schema.ts
├── src/
│   ├── app/
│   │   └── usecases/
│   └── main/
│       └── bootstrap.ts
├── generated/           # Generated by aurora codegen
├── package.json
└── tsconfig.json

Configuration

Create aurora.config.ts in project root:

import { defineConfig } from "@aurora/cli";

export default defineConfig({
  schemas: ["./schemas/**/*.schema.ts"],
  output: "./generated",
  codegen: {
    react: true,
    zustand: false,
    client: true,
  },
  dev: {
    port: 3000,
    natsUrl: "nats://localhost:4222",
    storagePath: "./data",
  },
});

Troubleshooting

Code generation fails

# Validate schemas first
aurora check

# Force regeneration
aurora codegen --force

Workers not connecting to NATS

# Check NATS is running
curl http://localhost:8222/varz

# Verify URL
aurora dev --workers --natsUrl nats://localhost:4222

Watch mode not detecting changes

# Check file permissions
ls -la schemas/

# Restart watch mode
# Ctrl+C then: aurora dev --watch
