What is @types/pbf?
@types/pbf provides TypeScript type definitions for the pbf library, which is a low-level, fast, and efficient library for encoding and decoding Protocol Buffers (protobuf) data.
What are @types/pbf's main functionalities?
Encoding Data
This feature allows you to encode data into a Protocol Buffers format. The code sample demonstrates how to write a varint (variable-length integer) and get the encoded buffer.
const Pbf = require('pbf');
const pbf = new Pbf();
pbf.writeVarint(123); // Write a varint
const buffer = pbf.finish(); // Get the encoded buffer
Decoding Data
This feature allows you to decode data from a Protocol Buffers format. The code sample demonstrates how to read a varint from an encoded buffer.
const Pbf = require('pbf');
const buffer = new Uint8Array([0x08, 0x7b]); // Example buffer
const pbf = new Pbf(buffer);
const value = pbf.readVarint(); // Read a varint
console.log(value); // 123
Handling Nested Messages
This feature allows you to handle nested messages within Protocol Buffers. The code sample demonstrates how to write a nested message with a varint and a string field.
const Pbf = require('pbf');
const pbf = new Pbf();
pbf.writeMessage(1, (pbf) => {
pbf.writeVarintField(1, 123);
pbf.writeStringField(2, 'example');
});
const buffer = pbf.finish();
Other packages similar to @types/pbf
protobufjs
protobufjs is a comprehensive library for working with Protocol Buffers in JavaScript. It provides both runtime and static code generation, making it more versatile than pbf. It also includes a robust set of features for working with .proto files, which is not a focus of pbf.
google-protobuf
google-protobuf is the official Protocol Buffers library for JavaScript provided by Google. It offers a complete implementation of Protocol Buffers, including support for all protobuf features. It is more feature-rich but also heavier and potentially slower than pbf.
