htt-post-message

A generic messaging component to send HTTP style message payloads over the window.postMessage API. Requires an implementation of window postMessage proxy such as 'window-post-message-proxy'.

Installation

npm install -g http-post-message

Usage

The HttpPostMessage takes in an object that implements the IPostMessage interface which is just one method postMessage which returns a Promise.

In the case below we created a mock postMessage proxy, but in normal usage you would likely use the accompanying library window-post-message-proxy.

import * as hpm from 'http-post-message';

const stubWindowPostMessageProxy: hpm.IPostMessage = {
  postMessage(message: any) {
    console.log(message);
    return Promise.resolve(message):
  }
}

const httpPostMessage = new hpm.HttpPostMessage(stubWindowPostMessageProxy);

httpPostMessage.get('target/path')
  .then(response => {
    ...
  });

Methods

The object supports all the standard http methods, get, post, put, patch, and delete. You can also send an IRequest object directly to the lower-level send method.
