Quickstart

Follow the commands listed below.

$ corepack enable utoo
$ mkdir showcase && cd showcase
$ ut create egg@beta
$ ut install
$ ut run dev
$ open http://localhost:7001

Node.js >= 22.18.0 required.

Monorepo Structure

This project is structured as a utoo monorepo with the following packages:

• packages/egg - Main Eggjs framework
• examples/helloworld-commonjs - CommonJS example application
• examples/helloworld-typescript - TypeScript example application
• site - Documentation website

The monorepo uses utoo catalog mode for centralized dependency management, ensuring consistent versions across all packages.

Development Commands

# Install dependencies for all packages
ut install --from pnpm

# Build all packages
ut run build

# Test all packages
ut run test

# Run specific package commands
ut --filter=egg run test
ut --filter=@examples/helloworld-typescript run dev
ut --filter=site run dev

Local External Services

Some DAL, ORM, Redis, and ecosystem benchmark paths need local MySQL and Redis services. Start the repository-aligned Docker services before running those tests on a clean machine:

ut run dev:services:start

This starts MySQL 8 and Redis 7, matching the main CI service versions, and creates the databases used by local DAL/ORM/e2e fixtures: test, apple, banana, test_runtime_datasource, test_runtime_dao, test_dal_plugin, test_dal_standalone, cnpmcore, and cnpmcore_unittest.

Useful commands:

ut run dev:services:status
ut run dev:services:stop
ut run dev:services:reset

The default host ports are 127.0.0.1:3306 for MySQL and 127.0.0.1:6379 for Redis. If either port is already used, the start command stops before changing containers. Keep using the existing service if it is compatible with CI, or stop it and run the command again. You can change Docker host ports with EGG_DEV_SERVICES_MYSQL_PORT and EGG_DEV_SERVICES_REDIS_PORT; however, the full DAL/ORM/Redis local test path still expects the default host ports.

Image overrides are available for compatibility checks:

EGG_DEV_SERVICES_MYSQL_IMAGE=mysql:5.7 ut run dev:services:start
EGG_DEV_SERVICES_REDIS_IMAGE=redis:7 ut run dev:services:start

Run ut run dev:services:reset before switching MySQL image families, for example between MySQL 8 and MySQL 5.7, because MySQL data directories are not downgrade-compatible across major versions.

Current hard-coded service assumptions:

• Redis plugin fixtures under plugins/redis/test/fixtures/apps/**/config.* use 127.0.0.1:6379; skipped Redis plugin tests become runnable when that port is available.
• Session Redis fixtures under plugins/session/test/fixtures/redis-session/config/config.default.js use 127.0.0.1:6379.
• DAL runtime tests in tegg/core/dal-runtime/test/DataSource.test.ts and tegg/core/dal-runtime/test/DAO.test.ts use local MySQL on port 3306.
• DAL module fixtures in tegg/plugin/dal/test/fixtures/apps/dal-app/modules/dal/module.yml and tegg/standalone/standalone/test/fixtures/dal-*/module.yml use local MySQL on port 3306.
• ORM fixtures in tegg/plugin/orm/test/fixtures/prepare.js and tegg/plugin/orm/test/fixtures/apps/orm-app/config/config.default.ts use local MySQL on port 3306.
