Enhance Your Streaming Efficiency with Base64-Stream

Base64-Stream is a powerful Node.js library that allows you to encode and decode Base64 data streams effortlessly. This library is perfect for handling various types of data efficiently and effectively, making it an essential tool for developers working with streaming data.

Introduction to Base64-Stream

Base64-Stream provides a seamless way to convert data to and from Base64 encoding in streaming applications. Whether you’re dealing with file uploads, downloads, or any other type of data stream, this library helps you manage the encoding/decoding process smoothly.

API Examples and Code Snippets

Installing Base64-Stream

npm install base64-stream

Encoding Data Stream

You can easily encode data streams using the Base64Encode class. Here’s a simple example:

const fs = require('fs');
const Base64Encode = require('base64-stream').Base64Encode;

const input = fs.createReadStream('input.txt');
const output = fs.createWriteStream('output.b64');
input.pipe(new Base64Encode()).pipe(output);

Decoding Data Stream

Decoding a Base64 stream is just as straightforward with the Base64Decode class:

const fs = require('fs');
const Base64Decode = require('base64-stream').Base64Decode;

const input = fs.createReadStream('input.b64');
const output = fs.createWriteStream('output.txt');
input.pipe(new Base64Decode()).pipe(output);

Handling Errors

Base64-Stream provides error handling mechanisms to ensure your application runs smoothly. Here’s an example:

const fs = require('fs');
const Base64Encode = require('base64-stream').Base64Encode;

const input = fs.createReadStream('input.txt');
const output = fs.createWriteStream('output.b64');
const encoder = new Base64Encode();

encoder.on('error', (err) => {
  console.error('Encoding error:', err);
});

input.pipe(encoder).pipe(output);

Integration with Other Streams

You can integrate Base64-Stream with other stream-based tools and libraries for more advanced use cases:

const zlib = require('zlib');
const fs = require('fs');
const Base64Encode = require('base64-stream').Base64Encode;

const input = fs.createReadStream('input.txt');
const output = fs.createWriteStream('output.b64.gz');
input.pipe(zlib.createGzip()).pipe(new Base64Encode()).pipe(output);

Example Application

Here’s a complete example of a file uploader that encodes files as Base64 before saving them to disk:

const http = require('http');
const fs = require('fs');
const Base64Encode = require('base64-stream').Base64Encode;

const server = http.createServer((req, res) => {
  if (req.method === 'POST') {
    const output = fs.createWriteStream('uploaded_file.b64');
    req.pipe(new Base64Encode()).pipe(output);

    req.on('end', () => {
      res.writeHead(200, { 'Content-Type': 'text/plain' });
      res.end('File uploaded and encoded successfully');
    });
  } else {
    res.writeHead(200, { 'Content-Type': 'text/html' });
    res.end('
Upload
');
  }
});

server.listen(8080, () => {
  console.log('Server listening on port 8080');
});

In conclusion, Base64-Stream is an excellent tool for managing Base64-encoded data streams in Node.js applications. It ensures efficient data encoding/decoding processes and integrates well with other stream-based libraries and tools.
