How to do Base64 encoding in node.js?

Question

Does node.js have built-in base64 encoding yet?

The reason why I ask this is that final() from crypto can only output hex, binary or ascii

Answer 1

Buffers can be used for taking a string or piece of data and doing base64 encoding of the result. For example:

You can install Buffer via npm like :- npm i buffer --save

you can use this in your js file like this :-

var buffer = require('buffer/').Buffer;

->> console.log(buffer.from("Hello Vishal Thakur").toString('base64'));
SGVsbG8gVmlzaGFsIFRoYWt1cg==  // Result

->> console.log(buffer.from("SGVsbG8gVmlzaGFsIFRoYWt1cg==", 'base64').toString('ascii'))
Hello Vishal Thakur   // Result
