IOPA
iopa-http

Build Status IOPA limerun

NPM

About

iopa-http is an API-First fabric for the Internet of Things (IoT) and for Microservices Container-Based Architectures (MCBA) based on the Internet of Protocols Alliance (IOPA) specification

It servers HTTP messages in standard IOPA format and allows existing middleware for Connect, Express and limerun projects to consume/send each mesage.

Written in native javascript for maximum performance and portability to constrained devices and services. If you prefer to use the core Node.js 'http' transport, then see the package iopa-http.

Status

Working Release

Includes:

Server Functions

  • HTTP/1.1 parser that matches full Node.js 'http' functions
  • Works over TCP, UDP and other IOPA transports
  • Pipelined requests and processing buffering
  • Optimized pure javascript parser with no expensive callouts to C
  • Optimized for both TCP and UDP transports with identical API

Client Functions

  • HTTP/1.1 formatter and response matcher
  • Works over TCP, UDP and other IOPA transports
  • Pipelined requests and response matching
  • Optimized for both TCP and UDP transports with identical API

Installation

npm install iopa-http

Usage

Simple Hello World Server and Client

const iopa = require('iopa')
  
const IopaTCP =  require('iopa-tcp'),
    IopaHTTP = require('iopa-http')
  
var app = new iopa.App();
app.use(IopaTCP);
app.use(IopaHTTP);

app.use(function (context, next) {
  context.response["iopa.Body"].end("<HTML><HEAD></HEAD><BODY>Hello World</BODY>");
  return next();
});

var server = app.createServer("tcp:");
server.listen()
  .then(function () {
      return server.connect("http://localhost:" + server["server.LocalPort"]);})
  .then(function(client) {
      return client.send("/", "GET");})
  .then(function (response) {
      response["iopa.Body"].pipe(process.stdout);
      server.close();
    });
