Writing JSON object to a JSON file with fs.writeFileSync
I don't think you should use the synchronous approach, asynchronously writing data to a file is better also stringify the output if it's an object.
Note: If output is a string, then specify the encoding and remember the flag options as well.:
const fs = require('fs');const content = JSON.stringify(output);fs.writeFile('/tmp/phraseFreqs.json', content, 'utf8', function (err) { if (err) { return console.log(err); } console.log("The file was saved!");}); Added Synchronous method of writing data to a file, but please consider your use case. Asynchronous vs synchronous execution, what does it really mean?
const fs = require('fs');const content = JSON.stringify(output);fs.writeFileSync('/tmp/phraseFreqs.json', content);
