Create Directory When Writing To File In Node.js

Question

I\'ve been tinkering with Node.js and found a little problem. I\'ve got a script which resides in a directory called data. I want the script to write some data to

Answer 1

With node-fs-extra you can do it easily.

Install it

npm install --save fs-extra

Then use the outputFile method. Its documentation says:

Almost the same as writeFile (i.e. it overwrites), except that if the parent directory does not exist, it's created.

You can use it in three ways:

Callback style

const fse = require('fs-extra');

fse.outputFile('tmp/test.txt', 'Hey there!', err => {
  if(err) {
    console.log(err);
  } else {
    console.log('The file was saved!');
  }
})

Using Promises

If you use promises, and I hope so, this is the code:

fse.outputFile('tmp/test.txt', 'Hey there!')
   .then(() => {
       console.log('The file was saved!');
   })
   .catch(err => {
       console.error(err)
   });

Sync version

If you want a sync version, just use this code:

fse.outputFileSync('tmp/test.txt', 'Hey there!')

For a complete reference, check the outputFile documentation and all node-fs-extra supported methods.
