Here’s the README in markdown format that you can copy-paste into your README.md file:

FRED Series Data Charts Monorepo Project

This monorepo includes two separate projects:

1. web-app: A React application for managing and displaying chart data.
2. proxy-server: An Express-based proxy server to handle CORS and API requests.

Monorepo Setup

The projects are managed with Yarn Workspaces and share dependencies where possible.

Requirements

• Node.js (>= 14.x)
• Yarn (>= 1.22)

Installation

Clone the repository and navigate to the root directory.

Run the following command to install all dependencies for both projects:

yarn install

Running the Projects

Both projects can be run together using a single command:

yarn start

This command uses concurrently to start:

• web-app on port 3000 (default for Vite).
• proxy-server on port 4000 (default for Express).

Project 1: Chart Management

Overview

web-app is a React application designed to handle and display various types of charts (e.g., line, bar charts). It utilizes libraries like Ant Design, ChartJs, and RTK for state management.

Available Commands

• Development: Start the React app in development mode.

  yarn dev:web-app

• Build: Generate a production build of the app.

  yarn build:web-app

• Build: Run unit test

  yarn test:web-app

Dependencies

Key libraries:

• chart.js: Charting Library.
• @ant-design: Core Components with Ant Design styling.
• @reduxjs/toolkit: Simplifies Redux state management.
• dayjs: Lightweight date library.
• tailwindcss: Utility-first CSS framework.

Folder Structure

• src/components: Contains reusable components.
• src/store: Redux store setup.
• src/utils: Utility functions and modules.

Configuration

Prettier and ESLint configurations are included for code formatting and linting.

Project 2: Proxy Server

Overview

proxy-server is a lightweight Express server designed to handle CORS and proxy API requests to bypass restrictions, enhancing the security and stability of API requests.

Available Commands

• Start: Run the proxy server.

  yarn dev:proxy-server

Dependencies

Key libraries:

• express: Server framework.
• http-proxy-middleware: Proxy middleware for Express.
• cors: Middleware for handling CORS.

Folder Structure

• index.js: Main server file.
• middlewares: Contains any middleware functions, such as CORS handling.
• routes: Define API routes and request handling.

Configuration

The server is set up to run on port 4000 by default, but you can adjust this in index.js if needed.
