Api Rest Express

This project is a simple Express application that allows you to manage user data by adding and retrieving users stored in a text file without interface.

Requirements

Initial Setup

• Initialize the Node.js project and install dependencies (express, fs).
• Configure the server with Express.

Core Features

• POST /users: Add users by providing their name and surnames in JSON format. Validate inputs and store them in a text file.
• GET /users: Retrieve users from the file, with optional filters for name and surnames. Return all users if no filters are provided.

Error Handling

• Implement clear error messages for input validation and file handling issues.

Performance Optimization

• Consider using file handling techniques like streams for better performance with large data files.

Installation and Setup

1. Clone the repository:

   git clone https://github.com/crimanlor/Api-Rest-Express.git

2. Navigate to the project directory:

   cd your-repo

3. Install dependencies:

   npm install

4. Start the server:

Usage

1. Open your browser and go to http://localhost:3000.
2. Use a tool like Postman or ThunderClient to make requests to the POST and GET endpoints.
3. Add new users using the POST /users endpoint and view all stored users using the GET /users endpoint.
