$ mkdir showcase && cd showcase

This project is structured as a pnpm monorepo with the following packages:
packages/egg- Main Eggjs frameworkexamples/helloworld-commonjs- CommonJS example applicationexamples/helloworld-typescript- TypeScript example applicationsite- Documentation website
The monorepo uses pnpm catalog mode for centralized dependency management, ensuring consistent versions across all packages.
# Install dependencies for all packages
pnpm install
# Build all packages
pnpm run build
# Test all packages
pnpm run test
# Run specific package commands
pnpm --filter=egg run test
pnpm --filter=@examples/helloworld-typescript run dev
pnpm --filter=site run devSome 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:
utoo run dev:services:startThis 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:
utoo run dev:services:status
utoo run dev:services:stop
utoo run dev:services:resetThe 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 utoo run dev:services:start
EGG_DEV_SERVICES_REDIS_IMAGE=redis:7 utoo run dev:services:startRun utoo 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.*use127.0.0.1:6379; skipped Redis plugin tests become runnable when that port is available. - Session Redis fixtures under
plugins/session/test/fixtures/redis-session/config/config.default.jsuse127.0.0.1:6379. - DAL runtime tests in
