Key Insights

• 📁 Using JSON files for data persistence in Node APIs simplifies the process and enables quick setup.
• 👻 Implementing a front-end client allows for user interaction and visualization of data from the API.
• 🫠 The 'fs' module in Node.js facilitates reading and writing JSON files for data manipulation.
• 👻 Synchronous and asynchronous methods in Node allow for flexibility in handling server-side logic.

Questions & Answers

Q: What is a common practice for persistence when working with APIs in Node?

One common practice is saving data to JSON files to ensure it persists between server restarts and is easily accessible.

Q: How can JSON files be interacted with in a Node.js server?

In Node.js, the 'fs' module is used to read and write JSON files, allowing for easy access and manipulation of data.

Q: Why is building a front-end client important when working with APIs?

A front-end client enables users to interact with the API, submit data, and visualize information, enhancing the usability and functionality of the API.

Q: How can client-side JavaScript interact with server-side APIs using Node.js?

By making asynchronous requests to API routes, client-side JavaScript can send, retrieve, and display data from the server.
