Step-by-Step Guide: From 0 to Hero

This guide will walk you through the essentials of working on this project, from setup to advanced practices.

---

1. Project Setup

1. Clone the repository

   git clone <your-repo-url>
   cd worksight

2. Install dependencies

   npm install

3. Start the development server

   npm run dev

   Visit http://localhost:3000 to see your app.

---

2. Documentation

• Comment your code as you write it. Use // for inline comments and /** ... */ for function/class docs.

• JSDoc Example:

  /**
   * Adds two numbers.
   * @param a First number
   * @param b Second number
   * @returns Sum of a and b
   */
  function add(a: number, b: number): number {
    return a + b;
  }

• Update the README with any new features or setup changes.

• Document API endpoints in a dedicated file (e.g., API.md).

---

3. Error Handling

• API routes: Always use try/catch for async logic.

  export default async function handler(req, res) {
    try {
      // ...your logic
    } catch (err) {
      res.status(500).json({ error: 'Internal Server Error' });
    }
  }

• Frontend: Show user-friendly error messages, not raw errors.

• Never leak sensitive info in error responses.

4. Testing

a. Install a test framework

npm install --save-dev jest @types/jest ts-jest

b. Configure Jest (if using TypeScript)

Add to package.json or create jest.config.js:

module.exports = {
  preset: 'ts-jest',
  testEnvironment: 'node',
};

c. Write your first test

Create a file like __tests__/math.test.ts:

import { add } from '../utils/math';

describe('add', () => {
  it('adds two numbers', () => {
    expect(add(1, 2)).toBe(3);
  });
});

d. Run tests

npm test

e. Test API routes

Use node-mocks-http or supertest to simulate API requests.

5. Exploring Libraries Offline

• Read code in node_modules/<library>.
• Look for README.md or docs in the package folder.
• Check .d.ts files for TypeScript types and API hints.
• Use your editor's intellisense/autocomplete.
• Create a scratch file and try out library functions, logging results.

---

6. Next Steps

• Refactor code for clarity and maintainability.
• Add more tests for edge cases.
• Improve documentation as you learn.
• Sketch new features or UI ideas.
• Practice by building small features or utilities.

Remember:
Start small, ask questions, and iterate. You’ll get better with every step!
