Marking this entry as part one as I don’t have much time tonight to work on this. Today was a break for me. Lots of relaxing and doing other things outside of worring about work or other projects. Much needed.

Though I did sit down for a bit tonight to learn how to easily write JSON to a file using nodejs. This is very similar to the reading values in from a JSON file post that I made last week, only doing the reverse.

This again uses the fs module to access the file system. All you need to do is to convert your object to a string using JSON.stringify(), then write it into the file like shown below:

const fs = require('fs');

let a = {
    name: 'Bob',
    age: '42'
}

fs.writeFileSync('sample.json', JSON.stringify(a, null, 2));

This will either create a new file named sample.json if it doesn’t exist, or overwrite the existing with the object.
