Random NodeJS Notes, JSON handling

To read existing JSON content from local files:

const fs = require('fs')
try {
    const dataBuffer = fs.readFileSync('<json file name>')
    const dataJSON = dataBuffer.toString()
    return JSON.parse(dataJSON)
} catch (e) {
    return []
}

To save text to JSON files:

const fs = require('fs')
const dataJSON = JSON.stringify(notes)
fs.writeFileSync('<json file name>', dataJSON)
