Introduction to Buffer JSON

Buffer JSON is a highly efficient library for handling JSON data in Buffers, optimizing both memory usage and performance. This library is ideal for high-performance applications requiring minimal latency and efficient memory management.

Core APIs

Creating a Buffer

The first step in using Buffer JSON is to create a Buffer. This is done with the following API:

const buffer = Buffer.alloc(256);

Encoding JSON to Buffer

Convert your JSON objects into Buffers to efficiently manage memory:

 const data = { key: 'value' }; const buffer = Buffer.from(JSON.stringify(data)); 

Decoding Buffer to JSON

You can easily decode your Buffers back into JSON objects:

 const jsonData = JSON.parse(buffer.toString()); 

Resizing Buffers

Resize a Buffer for dynamic data manipulation:

 const newBuffer = Buffer.alloc(512); buffer.copy(newBuffer); 

Advanced APIs

Concatenating Buffers

 const buffer1 = Buffer.from('Hello'); const buffer2 = Buffer.from('World'); const combinedBuffer = Buffer.concat([buffer1, buffer2]); 

Splitting Buffers

 const buffer = Buffer.from('HelloWorld'); const part1 = buffer.slice(0, 5); const part2 = buffer.slice(5); 

Encoding Buffers to Base64

 const buffer = Buffer.from('HelloWorld'); const base64String = buffer.toString('base64'); 

Decoding Base64 to Buffers

 const base64String = 'SGVsbG9Xb3JsZA=='; const buffer = Buffer.from(base64String, 'base64'); 

App Example

Here’s a small application showcasing the use of Buffer JSON APIs:

 const bufferJson = require('buffer-json');
// Create JSON data and encode it to Buffer const jsonData = { user: 'JohnDoe', age: 29 }; const encodedBuffer = Buffer.from(JSON.stringify(jsonData));
// Decode the Buffer back to JSON const decodedJson = JSON.parse(encodedBuffer.toString());
// Concatenate Buffers const bufferPart1 = Buffer.from('User: '); const bufferPart2 = Buffer.from(decodedJson.user); const combinedBuffer = Buffer.concat([bufferPart1, bufferPart2]);
// Output the result console.log(combinedBuffer.toString()); 

This app demonstrates creating and encoding JSON data to Buffers, decoding, and manipulating Buffers. It’s a robust example of how Buffer JSON can be utilized in real-world applications to optimize performance and memory usage.
