Features

SolidJS + TypeScript: Reactive, performant UI with full type safety
Tailwind CSS: Utility-first styling for responsive design
Todo Application: Full-featured todo list with create, read, and delete operations
TWD Testing: End-to-end tests demonstrating TWD capabilities with SolidJS
Mock API Server: JSON Server for local API mocking
SolidJS Router: Client-side routing with multiple pages

Recommended IDE Setup

VS Code + Solid Language Support

Testing with TWD

This project includes TWD tests for:

Hello World Page: Counter button functionality and page rendering
Todo List: CRUD operations (Create, Read, Delete) with mock API requests

Run tests by executing TWD in your testing environment. Refer to the TWD documentation for detailed testing instructions.

Project Setup

npm install # or pnpm install or yarn install

Those template dependencies are maintained via pnpm via pnpm up -Lri. This is the reason you see a pnpm-lock.yaml. That being said, any package manager will work.

Compile and Hot-Reload for Development

npm run serve:dev

This command runs both the development server and the mock API server in parallel. The app will be available at http://localhost:5173 and the API at http://localhost:3001.

Run Tests with TWD

npm run dev

TWD is automatically initialized in development mode and will be available in the browser.

Compile and Minify for Production

npm run build

Builds the app for production to the dist folder. It correctly bundles Solid in production mode and optimizes the build for the best performance. The build is minified and the filenames include the hashes.

Available Scripts

npm run dev or npm start: Run the Vite dev server only at http://localhost:5173
npm run build: Build for production
npm run serve: Run the mock API server only at http://localhost:3001
npm run serve:dev: Run both dev server and API server in parallel

Deployment

You can deploy the dist folder to any static host provider (netlify, surge, now, etc.)
