Node.js - atob / btoa functions equivalents
4 points
In this short article, we would like to present equivalents for btoa() and atob() functions under Node.js.
Quick solutions:
xxxxxxxxxx1
const btoa = (text) => Buffer.from(text, 'binary').toString('base64');xxxxxxxxxx1
const atob = (base64) => Buffer.from(base64, 'base64').toString('binary');
btoa() and atob() are common JavaScript functions, but they are not available under Node.js, so it is necessary to use some equivalents.
"btoa" should be read as "binary to ASCII". btoa() function converts binary to Base64-encoded ASCII string.
xxxxxxxxxx1
const btoa = (text) => {2
const buffer = Buffer.from(text, 'binary');3
return buffer.toString('base64');4
};5

// Usage example:8

console.log(btoa('This is text...')); // VGhpcyBpcyB0ZXh0Li4u
"atob" should be read as "ASCII to binary". atob() function converts Base64-encoded ASCII string to binary.
xxxxxxxxxx1
const atob = (base64) => {2
const buffer = Buffer.from(base64, 'base64');3
return buffer.toString('binary');4
};5
