superagent-protobuf

Adds protobuf.js encoding and decoding support to superagent

Supports both superagent and supertest on Node.js.

Installation

Install using npm:

$ npm install superagent-protobuf

Usage

superagent-protobuf adds the proto(...) and sendProto(...) methods onto an existing superagent or supertest object.

Installing

// Using require(...).
const request = require('superagent');
require('superagent-protobuf')(request);

// Using ES6 imports.
import request from 'superagent';
import addProtobuf from 'superagent-protobuf';

addProtobuf(request);

The same methods above work with supertest as well:

const request = require('supertest');
require('superagent-protobuf')(request);

`request.proto(...)`

Decodes a protobuf message with a specified message type.

Note that this method sets the Accept header to application/x-protobuf.

Example usage:

// Send a request and expect a MessageType protobuf.js message back.
let res = await request.get('.../some-endpoint')
  .proto(MessageType);

// The resulting message is stored in the body property.
console.log(res.body);

`request.sendProto(...)`

Encodes a protobuf message with the Content-Type application/x-protobuf.

Example usage:

let res = await request.post('.../some-endpoint')
  .sendProto(MessageType.create({
    my_field: 1  
  }));

This can also be combined with request.proto(...) to receive a protobuf message as well:

let outbound = MessageType.create({
  my_field: 1  
});

// Sending a MessageType message and receiving an AnotherMessageType
// message.
let res = await request.post('.../some-endpoint')
  .sendProto(outbound)
  .proto(AnotherMessageType);

let inbound = res.body;

// Printing out the message.
console.log(inbound);
