+# Getting Started with the OpenHands Frontend
+
+## Overview
+
+This is the frontend of the OpenHands project. It is a React application that provides a web interface for the OpenHands project.
+
+## Tech Stack
+
+- Remix SPA Mode (React + Vite + React Router)
+- TypeScript
+- Redux
+- TanStack Query
+- Tailwind CSS
+- i18next
+- React Testing Library
+- Vitest
+- Mock Service Worker
+
+## Getting Started
+
+### Prerequisites
+
+- Node.js 20.x or later
+- `npm`, `bun`, or any other package manager that supports the `package.json` file
+
+### Installation
+
+```sh
+# Clone the repository
+git clone https://github.com/All-Hands-AI/OpenHands.git
+
+# Change the directory to the frontend
+cd OpenHands/frontend
+
+# Install the dependencies
+npm install
+```
+
+### Running the Application in Development Mode
+
+We use `msw` to mock the backend API. To start the application with the mocked backend, run the following command:
+
+```sh
+npm run dev
+```
+
+This will start the application in development mode. Open [http://localhost:3001](http://localhost:3001) to view it in the browser.
+
+**NOTE: The backend is _partially_ mocked using `msw`. Therefore, some features may not work as they would with the actual backend.**
+
+See the [Development.md](../Development.md) for extra tips on how to run in development mode.
+
+### Running the Application with the Actual Backend (Production Mode)
+
+To run the application with the actual backend:
+
+```sh
+# Build the application from the root directory
+make build
+
+# Start the application
+make run
+```
+Or to run backend and frontend separately.
+
+```sh
+# Start the backend from the root directory
+make start-backend
+
+# Serve the frontend
+make start-frontend or
+cd frontend && npm start -- --port 3001
+```
+
+Start frontend with Mock Service Worker (MSW), see testing for more info.
+```sh
+npm run dev:mock or npm run dev:mock:saas
+```
+
+### Environment Variables
+
+The frontend application uses the following environment variables:
+
+| Variable                    | Description                                                            | Default Value    |
+| --------------------------- | ---------------------------------------------------------------------- | ---------------- |
+| `VITE_BACKEND_BASE_URL`     | The backend hostname without protocol (used for WebSocket connections) | `localhost:3000` |
+| `VITE_BACKEND_HOST`         | The backend host with port for API connections                         | `127.0.0.1:3000` |
+| `VITE_MOCK_API`             | Enable/disable API mocking with MSW                                    | `false`          |
+| `VITE_MOCK_SAAS`            | Simulate SaaS mode in development                                      | `false`          |
+| `VITE_USE_TLS`              | Use HTTPS/WSS for backend connections                                  | `false`          |
+| `VITE_FRONTEND_PORT`        | Port to run the frontend application                                   | `3001`           |
+| `VITE_INSECURE_SKIP_VERIFY` | Skip TLS certificate verification                                      | `false`          |
+| `VITE_GITHUB_TOKEN`         | GitHub token for repository access (used in some tests)                | -                |
+
+You can create a `.env` file in the frontend directory with these variables based on the `.env.sample` file.

+
+#### Components
+
+Components are organized into folders based on their **domain**, **feature**, or **shared functionality**.
+
+```sh
+components
+├── features # Domain-specific components
+├── layout
+├── modals
+└── ui # Shared UI components
+```
+
+### Features
+
+- Real-time updates with WebSockets
+- Internationalization
+- Router data loading with Remix
+- User authentication with GitHub OAuth (if saas mode is enabled)
+
+## Testing
+
+### Testing Framework and Tools
+
+We use the following testing tools:
+- **Test Runner**: Vitest
+- **Rendering**: React Testing Library
+- **User Interactions**: @testing-library/user-event
+- **API Mocking**: [Mock Service Worker (MSW)](https://mswjs.io/)
+- **Code Coverage**: Vitest with V8 coverage
+
+### Running Tests
+
+To run all tests:
+```sh
+npm run test
+```
+
+To run tests with coverage:
+```sh
+npm run test:coverage
+```
+
+### Testing Best Practices
+
+1. **Component Testing**
+   - Test components in isolation
+   - Use our custom [`renderWithProviders()`](https://github.com/All-Hands-AI/OpenHands/blob/ce26f1c6d3feec3eedf36f823dee732b5a61e517/frontend/test-utils.tsx#L56-L85) that wraps the components we want to test in our providers. It is especially useful for components that use Redux
+   - Use `render()` from React Testing Library to render components
+   - Prefer querying elements by role, label, or test ID over CSS selectors
+   - Test both rendering and interaction scenarios
+
+2. **User Event Simulation**
+   - Use `userEvent` for simulating realistic user interactions
+   - Test keyboard events, clicks, typing, and other user actions
+   - Handle edge cases like disabled states, empty inputs, etc.
+
+3. **Mocking**
+   - We test components that make network requests by mocking those requests with Mock Service Worker (MSW)
+   - Use `vi.fn()` to create mock functions for callbacks and event handlers
+   - Mock external dependencies and API calls (more info)[https://mswjs.io/docs/getting-started]
+   - Verify mock function calls using `.toHaveBeenCalledWith()`, `.toHaveBeenCalledTimes()`
+
+4. **Accessibility Testing**
+   - Use `toBeInTheDocument()` to check element presence
+   - Test keyboard navigation and screen reader compatibility
+   - Verify correct ARIA attributes and roles
+
+5. **State and Prop Testing**
+   - Test component behavior with different prop combinations
+   - Verify state changes and conditional rendering
+   - Test error states and loading scenarios
+
+6. **Internationalization (i18n) Testing**
+   - Test translation keys and placeholders
+   - Verify text rendering across different languages
+
+Example Test Structure:
+```typescript
+import { render, screen } from "@testing-library/react";
+import userEvent from "@testing-library/user-event";
+import { describe, it, expect, vi } from "vitest";
+
+describe("ComponentName", () => {
+  it("should render correctly", () => {
+    render(<Component />);
+    expect(screen.getByRole("button")).toBeInTheDocument();
+  });
+
+  it("should handle user interactions", async () => {
+    const mockCallback = vi.fn();
+    const user = userEvent.setup();
+
+    render(<Component onClick={mockCallback} />);
+    const button = screen.getByRole("button");
+
+    await user.click(button);
+    expect(mockCallback).toHaveBeenCalledOnce();
+  });
+});
+```
+
+### Example Tests in the Codebase
+
+For real-world examples of testing, check out these test files:
+
+1. **Chat Input Component Test**:
+   [`__tests__/components/chat/chat-input.test.tsx`](https://github.com/All-Hands-AI/OpenHands/blob/main/frontend/__tests__/components/chat/chat-input.test.tsx)
+   - Demonstrates comprehensive testing of a complex input component
+   - Covers various scenarios like submission, disabled states, and user interactions
+
+2. **File Explorer Component Test**:
+   [`__tests__/components/file-explorer/file-explorer.test.tsx`](https://github.com/All-Hands-AI/OpenHands/blob/main/frontend/__tests__/components/file-explorer/file-explorer.test.tsx)
+   - Shows testing of a more complex component with multiple interactions
+   - Illustrates testing of nested components and state management
+
+### Test Coverage
+
+- Aim for high test coverage, especially for critical components
+- Focus on testing different scenarios and edge cases
+- Use code coverage reports to identify untested code paths
+
+### Continuous Integration
+
+Tests are automatically run during:
+- Pre-commit hooks
+- Pull request checks
+- CI/CD pipeline
