Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

iframe-phone

Simplified communication between the parent site and iframe based on window.postMessage()

Build

To install dependencies (browserify) run:

npm install

To build the library in dist directory run:

npm run build

Usage

iframe-phone is a UMD bundle (dist/iframe-phone.js). You can include it directly or use some module system (e.g. browserify or RequireJS). When you include it directly, it will be available under global iframePhone name.

parent

var phone = new iframePhone.ParentEndpoint(iframeElement, function () {
  console.log("connection with iframe established");
});
phone.post('testMessage', 'abc');
phone.addListener('response', function (content) {
  console.log("parent received response: " + content);
});

iframe

// IFrameEndpoint instance is a singleton (iframe can't have multiple parents anyway).
var phone = iframePhone.getIFrameEndpoint();
phone.addListener('testMessage', function (content) {
  console.log("iframe received message: " + content);
  phone.post('response', 'got it');
});
// Initialize connection after all message listeners are added!
phone.initialize();

Changelog

1.3.1

  • Fixed issues with index.d.ts types file for latest TypeScript

1.3.0

  • Added index.d.ts types file so the library can be consumed by TypeScript
  • Added removeListener() to IFrameEndpoint
  • Added removeAllListeners() to ParentEndpoint
  • Added call to removeAllListeners() in IFrameEndpoint and ParentEndpoint disconnect()

1.2.1

  • Fix structured clone test that resulted in no actual use of structured clone even when the browser supported it. This might speed up the message passing.
  • Fix typo in disconnect which was preventing an real disconnect

1.2.0

  • Added support of file:// protocol (both ParentEndpoint and IframeEndpoint need to be upgraded to >= v1.2.0)
  • Origin check removed from IframeEndpoint (it didn't provide any security)
