Playwright Test API

This project is a simple API server built with Node.js and Express. It is designed to be a testing backend for the "API testing with Playwright" tutorial for CircleCI.

It provides basic endpoints for fetching users, creating users, and simulating a user login.

Prerequisites

• Node.js (v16 or later)

• npm (usually comes with Node.js)

Clone the repository or save the index.js and package.json files to a new directory.

Install the required dependencies by running:

npm install

Running the Server To start the API server, run the following command from the project's root directory:

npm start

You should see a confirmation message in your terminal: Test API server is running on http://localhost:3000
