Get data from fs.readFile

Question

var content;
fs.readFile(\'./Index.html\', function read(err, data) {
    if (err) {
        throw err;
    }
    content = data;
});
console.log(content);
         


        

Answer 1

Use the built in promisify library (Node 8+) to make these old callback functions more elegant.

const fs = require('fs');
const util = require('util');

const readFile = util.promisify(fs.readFile);

async function doStuff() {
  try {
    const content = await readFile(filePath, 'utf8');
    console.log(content);
  } catch (e) {
    console.error(e);
  }
}
