feat: Migrate legacy buffer.atob(data) and buffer.btoa(data) APIs #98
Description
Description
This codemod should migrate the legacy buffer.atob(data) and buffer.btoa(data) APIs to the current recommended approaches. Specifically, it should replace buffer.atob(data) with Buffer.from(data, 'base64').toString('binary') and buffer.btoa(data) with Buffer.from(data, 'binary').toString('base64'). This migration is useful for updating codebases to use the current Node.js APIs.
If buffer is only use for these api the importation/requiring must be removed.
Examples
Migrating buffer.atob(data)
Before:
const buffer = require('node:buffer');
const data = 'SGVsbG8gV29ybGQh'; // "Hello World!" in base64
const decodedData = buffer.atob(data);
console.log(decodedData); // Outputs: Hello World!After:
const data = 'SGVsbG8gV29ybGQh'; // "Hello World!" in base64
const decodedData = Buffer.from(data, 'base64').toString('binary');
console.log(decodedData); // Outputs: Hello World!Migrating buffer.btoa(data)
Before:
const buffer = require('node:buffer');
const data = 'Hello World!';
const encodedData = buffer.btoa(data);
console.log(encodedData); // Outputs: SGVsbG8gV29ybGQhAfter:
const data = 'Hello World!';
const encodedData = Buffer.from(data, 'binary').toString('base64');
console.log(encodedData); // Outputs: SGVsbG8gV29ybGQh
