Read/Write JSON Files with Node.js

When you want to store data between server restarts with Node, JSON files are a simple and convenient choice. Whether you are reading a config file or persisting data for your application, Node has some built-in utilities that make it easy to read and write JSON files. Using JSON files in your app can be a useful way to persist data. We will look at a few different methods for working with JSON files.

In this tutorial we'll:
- Read JSON data from disk
- Learn to use fs module to interact with the filesystem
- Persist data to a JSON file
- Use JSON.parse and JSON.stringify to convert data to and from JSON format

I was searching for json read write whole day then found your
Just 10 min but explained every thing😍

An excellent tutorial. And it's exactly what I was looking for as I am about to embark on writing a simple editor for a very specific json file. I will be the sole user and the file is not terribly large, so I am not concerned about multiple users editing the file at the same time. And it's great that you have a written version of this for reference. Thank you!

Very clearly explained, thanks for the help! I had trouble trying to push a new item into an array in a json document, and this cleared some things up for me

I've been wandering for hours now, looking for JSON read/file help in Node.js (newbie here). Loading JSON faking a web request/response just wasn''t for me and for the project I'm currently on, yet it seemed the only, or at least the "way more popular" way (why in the world? you already possess the *.json file locally... just wondering). I can't really describe how big is my wish to say "Thank you". Thank you for existing, this video is exactly what I needed.
