Steedos Project & Package Format | Steedos 项目与软件包格式

Overview | 概述

A project is a Node.js/TypeScript workspace that runs the Steedos platform. A package is a self-contained, reusable module within the project containing objects, business logic, and UI components.

项目是运行 Steedos 平台的 Node.js 工作区。软件包是项目内独立的可复用模块。

Technology Stack | 技术栈

• Platform: Steedos (华炎魔方) - Enterprise Low-Code Platform
• Backend: Node.js + TypeScript + Moleculer microservices
• Frontend: React + Amis (Baidu low-code UI framework)
• Metadata: YAML files (.object.yml, .trigger.yml, .function.yml, etc.)
• Databases: MongoDB (metadata), PostgreSQL/MySQL (business data)
• Package Manager: Yarn (⚠️ 禁止使用 npm)

⚠️ CRITICAL: Package Manager

ALWAYS use yarn. NEVER use npm.

Action	✅ Correct	❌ Wrong
Init	yarn init -y	npm init -y
Install	yarn install / yarn add <pkg>	npm install / npm i
Start	yarn start	npm start / npm run start
Run script	yarn <script>	npm run <script>
Add dep	yarn add @steedos/server	npm install @steedos/server

Minimal Project Structure | 最小项目结构

my-steedos-project/
├── package.json              # NPM package configuration (REQUIRED)
├── .env                      # Environment variables (RECOMMENDED)
├── .gitignore               # Git ignore rules
└── steedos-packages/        # Custom packages (OPTIONAL)
    └── my-package/
        └── ...

Required Files | 必需文件

1. package.json (REQUIRED)

{
  "name": "my-steedos-project",
  "version": "0.0.1",
  "private": true,
  "workspaces": [
    "steedos-packages/*"
  ],
  "scripts": {
    "start": "steedos start",
    "build": "lerna run build"
  },
  "dependencies": {
    "@steedos/server": "latest"
  }
}

Key Points:

• @steedos/server dependency is REQUIRED
• workspaces for custom packages
• start script to run Steedos (use yarn start)

2. .env (RECOMMENDED)

PORT=5100
ROOT_URL=http://localhost:5100
MONGO_URL=mongodb://127.0.0.1:27017/steedos
TRANSPORTER=redis://127.0.0.1:6379
CACHER=redis://127.0.0.1:6379/1
STEEDOS_STORAGE_DIR=./steedos-storage
B6_LOG_LEVEL=warn

Naming Conventions | 命名规范

Type	Convention	Example
Package name	@steedos-packages/[name] (lowercase, hyphens)	@steedos-packages/contract-management
API names (YAML)	snake_case	orders, order_items, customer_name
Object file	{object_name}.object.yml	orders.object.yml
Field file	{field_name}.field.yml	order_number.field.yml
Trigger file	{trigger_name}.trigger.yml	orders_validate.trigger.yml
Function file	{function_name}.function.yml	approve_order.function.yml
Page files	{page_name}.page.yml + .page.amis.json	order_detail.page.yml
Application file	{app_code}.app.yml	order_management.app.yml

Best Practices | 最佳实践

1. One package per business domain: Group related objects and logic together
2. Triggers in triggers/ folder: NOT inside object folders
3. Functions in functions/ folder: NOT inside object folders
4. Pages as file pairs: Always create both .page.yml and .page.amis.json
5. Use snake_case for API names: Objects, fields, functions, triggers
6. Bilingual labels: Provide both English and Chinese labels
7. Validate after creation: Run npx @steedos/validate <packagePath> to catch issues early

Troubleshooting | 故障排除

Server won't start

• Verify MongoDB and Redis are running
• Check .env configuration

Packages not loading

• Verify package structure (package.json + package.service.js)
• Restart server after changes

Port already in use

• Change PORT in .env
• Kill existing process: lsof -ti:5100 | xargs kill
