Like any kind of apps, there are difficult issues to solve when we write Node apps.

In this article, we’ll look at some solutions to common problems when writing Node apps.

Correctly Exporting async Functions in Node.js

We can export an async function like any other function.

For instance, we can write:

async function doSomething() {
  // ...
}

module.exports.doSomething = doSomething;

We export doSomething like we can with any other function.

ReadFile in Base64 Nodejs

We can read a file into a base64 string by using the readFileSync method.

For instance, we can write:

const fs = require('fs');
const str = fs.readFileSync('/path/to/file.jpg', { encoding: 'base64' });

We pass in the 2nd argument with an object.

It has the encoding property set to 'base64' so that we can parse the file into a base64 string.

It’s returned and assigned to str .
