When to use this skill

Use this skill for Web frontend project development when you need to:

• Develop web frontend pages and interfaces
• Deploy static websites to CloudBase static hosting
• Integrate CloudBase Web SDK for database, cloud functions, and authentication
• Set up modern frontend build systems (Vite, Webpack, etc.)
• Handle routing and build configurations for static hosting

Do NOT use for:

• Mini-program development (use miniprogram-development skill)
• Backend service development (use cloudrun-development skill)
• UI design only (use ui-design skill, but may combine with this skill)

How to use this skill (for a coding agent)

1. Follow project structure conventions

   • Frontend source code in src directory
   • Build output in dist directory
   • Cloud functions in cloudfunctions directory
   • Use modern frontend build systems (Vite, etc.)

2. Use CloudBase Web SDK correctly

   • Always use SDK built-in authentication features
   • Never implement login logic in cloud functions
   • Use envQuery tool to get environment ID

3. Deploy and preview properly

   • Build project first (ensure npm install is executed)
   • Use relative paths for publicPath configuration
   • Use hash routing for better static hosting compatibility
   • Deploy to subdirectory if user doesn't specify root directory

Web Frontend Development Rules

Project Structure

1. Directory Organization:

   • Frontend source code should be stored in src directory
   • Build output should be placed in dist directory
   • Cloud functions should be in cloudfunctions directory

2. Build System:

   • Projects should use modern frontend build systems like Vite
   • Install dependencies via npm

3. Routing:

   • If the frontend project involves routing, use hash routing by default
   • Hash routing solves the 404 refresh issue and is more suitable for static website hosting deployment

Deployment and Preview

1. Static Hosting Deployment:

   • For frontend projects, after building, you can use CloudBase static hosting
   • First start local preview, then confirm with user if deployment to CloudBase static hosting is needed
   • When deploying, if user has no special requirements, generally do not deploy directly to root directory
   • Return deployed address in markdown link format

2. Local Preview:

   • To preview static web pages locally, navigate to the specified output directory and use npx live-server

3. Public Path Configuration:

   • When web projects are deployed to static hosting CDN, since paths cannot be known in advance, publicPath and similar configurations should use relative paths instead of absolute paths
   • This solves resource loading issues

CloudBase Web SDK Usage

1. SDK Integration:
   • If user's project needs database, cloud functions, and other features, need to introduce @cloudbase/js-sdk@latest in the web application

Important: Authentication must use SDK built-in features. It is strictly forbidden to implement login authentication logic using cloud functions!

const app = cloudbase.init({
  env: 'xxxx-yyy'; // Can query environment ID via envQuery tool
});
const auth = app.auth();

// Check current login state
let loginState = await auth.getLoginState();

if (loginState && loginState.user) {
  // Logged in
  const user = await auth.getCurrentUser();
  console.log('Current user:', user);
} else {
  // Not logged in - use SDK built-in authentication features
  // Method 1: Redirect to default login page (recommended)
  await auth.toDefaultLoginPage();
  
  // Method 2: Anonymous login
  // await auth.signInAnonymously();
}

Authentication Best Practices

1. Must use SDK built-in authentication: CloudBase Web SDK provides complete authentication features, including default login page, anonymous login, custom login, etc.

2. Forbidden to implement login using cloud functions: Do not create cloud functions to handle login logic, this is the wrong approach

3. User data management: After login, user information can be obtained via auth.getCurrentUser(), then stored to database

4. Error handling: All authentication operations should include complete error handling logic

Build Process

Web project build process: Ensure npm install command has been executed first, then refer to project documentation for building
