Run tests, linters, and builds to ensure nothing breaks -2. **Deliver complete solutions** - Don't leave partial implementations or half-fixed bugs -3. **Test edge cases** - Consider and handle error conditions, edge cases, and failure scenarios -4. **Verify the fix works** - Manually test the functionality you changed, take screenshots for UI changes -5. **Follow through** - If a test fails, debug and fix it; don't leave broken tests behind - -### Quality Standards - -- **Completeness**: Ensure all aspects of the issue are addressed -- **Correctness**: Verify changes work as expected through testing -- **Consistency**: Follow existing code patterns and conventions -- **Clarity**: Write clear code with meaningful variable/function names -- **Minimal changes**: Make surgical, focused changes that solve the problem without unnecessary refactoring - -## Technology Stack - -- **Frontend**: React 18.x with Material-UI v5/v6 -- **Backend**: Node.js with TypeScript -- **Desktop Framework**: Electron 39.x -- **MQTT Client**: [mqttjs](https://github.com/mqttjs/MQTT.js) v5.x -- **State Management**: Redux with redux-thunk -- **Build Tools**: webpack, TypeScript compiler -- **Testing**: Mocha + Chai for unit tests, Playwright for browser mode tests -- **Node.js**: Version 24 or higher required - -## Project Setup - -### Building and Running +### Using Playwright for Automated Testing ```bash -# Install dependencies -yarn install - -# Build the project -yarn build - -# Set password for browser testing +# Start server in background export MQTT_EXPLORER_USERNAME=admin -export MQTT_EXPLORER_PASSWORD=secretpassword +export MQTT_EXPLORER_PASSWORD=test123 +node dist/src/server.js & -# Start the application -yarn start -

-# Start with MCP introspection enabled -electron . --enable-mcp-introspection - -# Or with custom port -electron . --enable-mcp-introspection --remote-debugging-port=9223 -``` - -See `mcp.json` in the repository root for MCP configuration. - -## Writing Tests - -### Requirements for All Tests - -1. **Tests MUST be deterministic** - They should produce the same results every time they run -2. **Tests MUST be independent** - Each test should be able to run in isolation without depending on other tests -3. **Include screenshots** - Visual verification is required for UI changes -4. **Handle asynchronous operations properly** - This is an MQTT message queue tool - -### Best Practices for UI Tests - -#### 1. Use Given-When-Then Pattern -Structure tests with clear Given-When-Then comments to make them readable: - -```typescript -it('Given a JSON message sent to topic foo/bar/baz, the tree should display nested topics', async function () { - // Given: Mock MQTT publishes JSON to foo/bar/baz - // When: We wait for the topic to appear in the tree - // Then: Topic hierarchy should be visible (foo -> bar -> baz) -}) -``` - -#### 2. Wait for Elements, Don't Use Fixed Delays -Prefer `waitFor` over `sleep` whenever possible: - -```typescript -// ✓ Good: Wait for specific element -const topic = await page.locator('span[data-test-topic="kitchen"]') -await topic.waitFor({ state: 'visible', timeout: 5000 }) - -// ✗ Bad: Fixed delay without verification -await sleep(5000) -``` - -#### 3. Use Meaningful Assertions -Every test should have explicit assertions that verify the expected state: - -```typescript -// ✓ Good: Explicit assertion with meaningful message -const treeNodes = await page.locator('[class*="TreeNode"]') -const count = await treeNodes.count() -expect(count).to.be.greaterThan(0, 'Topic tree should contain nodes') - -// ✗ Bad: No assertion, only screenshot -await page.screenshot({ path: 'test.png' }) -``` - -#### 4. Test Data-Driven Scenarios -Write tests that describe the data flow: - -```typescript -it('Given messages sent to livingroom/lamp/state and livingroom/lamp/brightness, both should appear under livingroom/lamp', async function () { - // Test implementation verifies the specific data flow -}) -``` - -#### 5. Use Data Test Attributes -Leverage `data-test-*` attributes for reliable selectors: - -```typescript -// ✓ Good: Use data-test attributes -const topic = await page.locator('span[data-test-topic="kitchen"]') - -// ⚠ Acceptable: Use role/text when data attributes aren't available -const button = await page.locator('//button/span[contains(text(),"Connect")]') - -// ✗ Bad: Rely on CSS classes that may change -const topic = await page.locator('.MuiTreeItem-label') -``` - -#### 6. Verify Multiple Aspects -Test should verify both state and UI: - -```typescript -// Verify the action completed -const isVisible = await disconnectButton.isVisible() -expect(isVisible).to.be.true - -// Capture screenshot for visual verification -await page.screenshot({ path: 'test-screenshot-connection.png' }) -``` - -#### 7. Handle MQTT Asynchronous Nature -Account for message propagation time: - -```typescript -// Publish message -await mockClient.publish('topic/name', 'value') - -// Wait for UI to update -await page.locator(`text="value"`).waitFor({ timeout: 5000 }) - -// Verify state -const value = await page.textContent('.message-value') -expect(value).toBe('value') -``` - -### Handling MQTT Asynchronous Operations - -MQTT is inherently asynchronous. When writing tests: - -- **Wait for message propagation**: Use proper wait strategies (e.g., `await page.waitForSelector()`, `await sleep()`) -- **Don't assume immediate updates**: Messages take time to send, receive, and update the UI -- **Use event-based waiting**: Wait for specific UI elements or state changes rather than fixed timeouts when possible -- **Account for network latency**: MQTT broker communication involves network round trips - -### Example Test Pattern - -```typescript -// 1. Perform action (e.g., publish message) -await publishMessage(topic, payload) - -// 2. Wait for UI to update (not just arbitrary sleep) -await page.waitForSelector(`text="${expectedValue}"`, { timeout: 5000 }) - -// 3. Verify state -const value = await page.textContent('.message-value') -expect(value).toBe(expectedValue) - -// 4. Take screenshot for verification -await page.screenshot({ path: 'test-result.png' }) -``` - -### Running Tests - -```bash -# Run all tests -yarn test - -# Run specific test suites -yarn test:app -yarn test:backend -yarn test:mcp - -# Run linters -yarn lint -yarn lint:fix -``` - -### Running UI Tests (yarn test:ui) - -The UI tests require specific setup in the test environment: - -**Prerequisites:** -1. **Xvfb (X Virtual Framebuffer)** - Required for headless Electron testing - ```bash - # Start Xvfb on display :99 - Xvfb :99 -screen 0 1024x720x24 -ac & - export DISPLAY=:99 - ``` - -2. **Mosquitto MQTT Broker** - Required for MQTT message testing - ```bash - # Install mosquitto - sudo apt-get install -y mosquitto mosquitto-clients +1. **Login Page** (https://github.com/user-attachments/assets/383305e1-2169-433c-a668-5a05da0c343a) + - Enter username and password from environment variables + - Click "LOGIN" button - # Start mosquitto service - sudo systemctl start mosquitto +2. **Main Application After Login** (https://github.com/user-attachments/assets/cc4d665f-2665-4289-b2fc-dc4986f9ab5b) + - Application loads with sidebar, topic tree, value panel, and publish panel + - MQTT Connection modal appears automatically for first-time setup + - Configure broker connection (host, port, credentials, etc.) + - Click "CONNECT" to establish MQTT connection - # Verify it's running on port 1883 - sudo systemctl status mosquitto - ``` +3. **Application Features:** + - Topic tree on the left shows MQTT topic hierarchy + - Value panel shows selected topic's message content + - Publish panel allows sending MQTT messages + - Charts panel for numeric value visualization + - Settings drawer for app configuration -3. **@types/node** - Required for TypeScript compilation +### Debugging WebSocket Connection + +1. **Check server logs:** ```bash - yarn add -D @types/node + node dist/src/server.js 2>&1 | tee server.log ``` -**Running UI Tests:** -```bash -# Build the application first -yarn build +2. **Check browser WebSocket:** + - DevTools → Network → WS tab + - Look for socket.io connection + - Check Messages tab for authentication handshake -# Run UI tests with proper display -DISPLAY=:99 yarn test:ui +3. **Common WebSocket issues:** + - CORS errors: Check `ALLOWED_ORIGINS` environment variable + - Authentication errors: Verify credentials in sessionStorage + - Connection refused: Server not running or port blocked + +### Development vs Production + +**Development mode:** +```bash +yarn dev:server +# Runs webpack-dev-server with hot reload +# More verbose error messages +# Source maps enabled ``` -**Common Issues:** -- **"Timeout exceeded" in before hook**: Mosquitto is not running or not accessible on port 1883 -- **"Cannot find type definition file for 'node'"**: Run `yarn add -D @types/node` -- **Electron fails to launch**: Xvfb is not running or DISPLAY variable not set -- **Tests hang**: Check if old Electron/mosquitto processes are still running and kill them - -**Environment Cleanup:** +**Production mode:** ```bash -# Kill old Electron processes -ps aux | grep electron | grep -v grep | awk '{print $2}' | xargs kill -9 2>/dev/null - -# Kill old mosquitto processes (if running custom instance) -ps aux | grep mosquitto | grep -v grep | awk '{print $2}' | xargs kill -9 2>/dev/null +NODE_ENV=production yarn build:server +NODE_ENV=production node dist/src/server.js +# Minified bundles +# Generic error messages (security) +# HSTS enabled ``` -## MCP Introspection Testing - -The project supports MCP (Model Context Protocol) for automated testing: - -- Run tests: `yarn test:mcp` -- Configuration: `mcp.json` in repository root -- Tests launch the app with remote debugging on port 9222 - -## Project Structure - -- `app/` - Frontend React application -- `backend/` - Backend models, tests, and connection management -- `src/` - Electron main process and bindings -- `src/spec/` - Test specifications including MCP introspection tests - -## Code Style and Formatting - -### Linting - -The project uses TSLint with Airbnb config and Prettier for code formatting: - -```bash -# Run all linters -yarn lint - -# Run linters individually -yarn lint:prettier # Check Prettier formatting -yarn lint:tslint # Check TSLint rules -yarn lint:spellcheck # Check spelling in code - -# Auto-fix issues -yarn lint:fix # Fix TSLint and Prettier issues -yarn lint:tslint:fix # Fix TSLint issues only -yarn lint:prettier:fix # Fix Prettier issues only -``` - -### Code Style Rules - -- **Semicolons**: Never use semicolons (enforced by TSLint and Prettier) -- **Quotes**: Single quotes for strings -- **Indentation**: 2 spaces -- **Line length**: Maximum 120 characters (Prettier) / 200 characters (TSLint) -- **Arrow functions**: No parentheses for single parameters (`x => x + 1`) -- **Trailing commas**: Required for multiline objects and arrays (ES5 compatible) - -### TypeScript Guidelines - -- Enable strict null checks and no implicit any -- Use TypeScript interfaces for data structures -- Prefer `const` over `let`, avoid `var` -- Use type inference when possible, explicit types when clarity is needed - -## Dependency Management - -### Adding Dependencies - -```bash -# Add to root project -yarn add - -# Add to app (frontend) -cd app && yarn add - -# Add to backend -cd backend && yarn add - -# Add dev dependencies -yarn add -D -``` - -### Important Dependency Notes - -- Main dependencies are in the root `package.json` -- Frontend React app has its own dependencies in `app/package.json` -- Backend models and logic have dependencies in `backend/package.json` -- Always use `--frozen-lockfile` in CI to ensure reproducible builds -- Run `yarn install` after pulling changes that modify `yarn.lock` - -## Debugging - -### Development Mode - -```bash -# Start with hot reload for frontend -yarn dev - -# This runs two processes in parallel: -# 1. webpack-dev-server for the React app (port varies) -# 2. Electron in development mode with the --development flag -``` - -### Debugging TypeScript - -- Source maps are enabled in `tsconfig.json` -- Use `ts-node` for running TypeScript files directly -- Backend tests can be debugged with: `cd backend && yarn test-inspect` - -### Common Issues - -- **Build fails**: Clear `dist/` and `app/build/` directories, then rebuild -- **Electron won't start**: Ensure `yarn build` completed successfully -- **Tests fail**: Check if MQTT broker (mosquitto) is running for integration tests -- **UI not updating**: In dev mode, ensure webpack-dev-server is running - -## Deployment and Packaging - -### Creating Releases - -```bash -# Prepare release (updates version, changelog) -yarn prepare-release - -# Package the application for distribution -yarn package - -# Package with Docker (for consistent builds) -yarn package-with-docker -``` - -### Release Workflow - -- **Semantic commits required**: All commits must use semantic format (`feat:`, `fix:`, etc.) -- **Beta releases**: Create PR to `beta` branch with semantic commits -- **Production releases**: Create PR to `release` branch with semantic commits -- Semantic-release automatically handles versioning and changelog based on commit messages -- Builds are created for Windows, macOS, and Linux -
