Package description

What is @protobufjs/base64?

@protobufjs/base64 is a utility library for encoding and decoding base64 strings, primarily used in conjunction with Protocol Buffers in JavaScript. It provides efficient and straightforward methods to handle base64 encoding and decoding operations.

What are @protobufjs/base64's main functionalities?

Base64 Encoding

This feature allows you to encode a Uint8Array into a base64 string. The `encode` method takes a buffer, an offset, and a length as parameters.

const base64 = require('@protobufjs/base64');

const buffer = new Uint8Array([72, 101, 108, 108, 111]);
let encoded = base64.encode(buffer, 0, buffer.length);
console.log(encoded); // Outputs: SGVsbG8=

Base64 Decoding

This feature allows you to decode a base64 string back into a Uint8Array. The `decode` method takes a base64 string, a buffer to write to, and an offset as parameters.

const base64 = require('@protobufjs/base64');

const encoded = 'SGVsbG8=';
let buffer = new Uint8Array(encoded.length);
let length = base64.decode(encoded, buffer, 0);
console.log(buffer.subarray(0, length)); // Outputs: Uint8Array(5) [ 72, 101, 108, 108, 111 ]
