Step-by-Step Guide to Setting Up Your React Project for FairWorkly

Now that we've covered the tools and technologies we'll be using, let's dive into the practical steps of setting up your React project for FairWorkly. We'll start by initializing the project with Create React App and then configure the necessary tools and libraries.

1. Initialize the React + TypeScript Project

The first step is to create a new React project using Create React App (CRA) with the TypeScript template. CRA is a popular tool for setting up React projects with a pre-configured build process and development environment. Open your terminal and run the following command:

npx create-react-app fairworkly-frontend --template typescript
cd fairworkly-frontend

This command will create a new directory called fairworkly-frontend with a basic React project set up with TypeScript. Once the installation is complete, navigate into the project directory using the cd command.

2. Configure ESLint and Prettier

Next, we'll configure ESLint and Prettier to enforce code style and formatting. First, install the necessary ESLint and Prettier packages:

pnpm add -D eslint prettier eslint-config-prettier eslint-plugin-prettier eslint-plugin-react eslint-plugin-react-hooks @typescript-eslint/eslint-plugin @typescript-eslint/parser

Then, create an .eslintrc.js file in the root of your project with the following configuration:

module.exports = {
  parser: '@typescript-eslint/parser',
  extends: [
    'eslint:recommended',
    'plugin:react/recommended',
    'plugin:@typescript-eslint/recommended',
    'prettier',
  ],
  plugins: ['react', 'react-hooks', '@typescript-eslint', 'prettier'],
  rules: {
    'prettier/prettier': 'error',
    'react-hooks/rules-of-hooks': 'error',
    'react-hooks/exhaustive-deps': 'warn',
    'react/react-in-jsx-scope': 'off',
    '@typescript-eslint/explicit-function-return-type': 'off',
    '@typescript-eslint/no-explicit-any': 'warn',
  },
  settings: {
    react: {
      version: 'detect',
    },
  },
};

This configuration extends the recommended ESLint rules, as well as the Prettier and React-specific rules. It also configures ESLint to use the TypeScript parser and plugins.

Next, create a .prettierrc.js file in the root of your project with the following configuration:

module.exports = {
  semi: false,
  trailingComma: 'all',
  singleQuote: true,
  printWidth: 120,
  tabWidth: 2,
};

This configuration specifies the Prettier formatting options, such as using single quotes, no semicolons, and a print width of 120 characters.

Finally, add the following script to your package.json file to run ESLint and Prettier:

"scripts": {
  "lint": "eslint \".\\{js,jsx,ts,tsx}\"",
  "format": "prettier --write \".\\{js,jsx,ts,tsx,md}\""
}

Now you can run pnpm lint to check for ESLint errors and pnpm format to format your code with Prettier.

3. Set Up the Basic Folder Structure

A well-defined folder structure is crucial for maintaining a clean and organized codebase. We'll use a module-based folder layout, where each module represents a specific feature or area of the application. Create the following folders in the src/ directory:

src/
├── app/
├── modules/
│   ├── compliance/
│   ├── documents/
│   ├── payroll/
│   └── employee/
├── shared/
└── types/

Here's a breakdown of each folder:

• app/: Contains the main application components, such as the root component, routing configuration, and global styles.
• modules/: Contains the feature modules, such as compliance, documents, payroll, and employee.
• shared/: Contains shared components, hooks, and utilities that are used across multiple modules.
• types/: Contains global TypeScript type definitions.

Within each module folder (e.g., modules/compliance/), create the following subfolders:

modules/compliance/
├── pages/
├── features/
├── ui/
├── hooks/
└── types/

• pages/: Contains the main pages for the module.
• features/: Contains reusable features or components that are specific to the module.
• ui/: Contains UI components that are specific to the module.
• hooks/: Contains custom React hooks that are specific to the module.
• types/: Contains TypeScript type definitions that are specific to the module.

This modular structure promotes code reusability, maintainability, and scalability. It allows you to organize your code into logical units and makes it easier to understand and navigate the codebase.

4. Set Up Routing Entry (React Router v6)

To enable navigation between different pages in your application, we'll set up React Router v6. First, install the react-router-dom package:

pnpm add react-router-dom

Then, create a src/app/App.tsx file with the following content:

import React from 'react'
import { BrowserRouter, Routes, Route } from 'react-router-dom'
import { CompliancePage } from '../modules/compliance/pages/CompliancePage'
import { DocumentsPage } from '../modules/documents/pages/DocumentsPage'
import { PayrollPage } from '../modules/payroll/pages/PayrollPage'
import { EmployeePage } from '../modules/employee/pages/EmployeePage'

function App() {
  return (
    <BrowserRouter>
      <Routes>
        <Route path="/compliance" element={<CompliancePage />} />
        <Route path="/documents" element={<DocumentsPage />} />
        <Route path="/payroll" element={<PayrollPage />} />
        <Route path="/employee" element={<EmployeePage />} />
      </Routes>
    </BrowserRouter>
  )
}

export default App

This code sets up the basic routing configuration for your application. It defines routes for the compliance, documents, payroll, and employee modules and maps them to placeholder pages.

5. Set Up Basic State Management (Redux Toolkit / RTK Query)

For state management, we'll use Redux Toolkit and RTK Query. First, install the necessary packages:

pnpm add @reduxjs/toolkit react-redux

Then, create a src/app/store.ts file with the following content:

import { configureStore } from '@reduxjs/toolkit'

export const store = configureStore({
  reducer: {
    // Add your reducers here
  },
})

export type RootState = ReturnType<typeof store.getState>
export type AppDispatch = typeof store.dispatch

This code configures the Redux store using Redux Toolkit's configureStore function. It also exports the RootState and AppDispatch types for use in your components.

To use the Redux store in your application, wrap your root component with the Provider component from react-redux in src/index.tsx:

import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './app/App'
import { Provider } from 'react-redux'
import { store } from './app/store'

const root = ReactDOM.createRoot(
  document.getElementById('root') as HTMLElement
)
root.render(
  <React.StrictMode>
    <Provider store={store}>
      <App />
    </Provider>
  </React.StrictMode>
)

6. Implement Module-Based Folder Layout and Placeholder Components/Pages

Now that we have the basic project structure and tooling in place, let's implement the module-based folder layout and add some placeholder components and pages.

For each module (compliance, documents, payroll, employee), create a placeholder page component in the modules/<module>/pages/ directory. For example, create a src/modules/compliance/pages/CompliancePage.tsx file with the following content:

import React from 'react'

export function CompliancePage() {
  return (
    <div>
      <h1>Compliance Page</h1>
      <p>Welcome to the compliance page!</p>
    </div>
  )
}

Repeat this process for the other modules, creating placeholder pages for documents, payroll, and employee.

Within each module, you can also create placeholder components in the modules/<module>/features/ or modules/<module>/ui/ directories. These components can represent reusable features or UI elements that are specific to the module.

7. Add Basic Placeholder Components/Pages

As outlined in the scope, we need to add basic placeholder components/pages for each module. Here’s how you can approach this:

• Compliance Module:
  • Q&A Copilot Page: A simple page with a heading and placeholder text.
  • Roster Check Page: Another page with a heading and placeholder text.
• Documents Module:
  • Template/Contract Home Page: A page to manage document templates and contracts.
• Payroll Module:
  • Pay Run Check Page: A page for checking pay run status and details.
• Employee Module:
  • Self-Service Home Page: A home page for employees to access self-service features.

Create these placeholder pages within their respective module directories (modules/<module>/pages/).

Acceptance Criteria Achieved: Verifying Your Setup

To ensure that your initial setup is successful, let's revisit the acceptance criteria outlined at the beginning of this guide:

• [x] Project builds and runs with pnpm dev: You should be able to start the development server and see your React application running in your browser.
