Building a Base64 Encoder/Decoder with File Support in Next.js

1. 1Create a new Next.js project using `npx create-next-app` to set up the development environment
2. 2Build a Base64 encoder function using JavaScript's built-in `btoa` function to convert strings to Base64
3. 3Implement a Base64 decoder function using JavaScript's built-in `atob` function to convert Base64 strings back to original text
4. 4Add file support to the encoder/decoder by using the `FileReader` API to read file contents and convert them to Base64
5. 5Test the encoder/decoder with sample files and strings to ensure correct functionality

Frontend developers and full-stack engineers can benefit from this tutorial to enhance their web application's functionality and handle Base64 encoding/decoding efficiently

💡 Using JavaScript's built-in `btoa` and `atob` functions, you can easily build a Base64 encoder/decoder in Next.js and add file support using the `FileReader` API
