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

Ama mfe messages package

The @ama-mfe/messages package exposes a set of message interfaces to help the communication between a host application and module applications embedded via iframes.

These interfaces can be used to create messages compatible with the Amadeus Toolkit for Micro Frontends framework.

Installation

npm install @ama-mfe/messages

Message interfaces

The message interfaces exposed in this package cover common use cases such as:

  • Navigation: an embedded application requests its host to navigate to a specific URL.
  • Resize: an embedded application's dimension changed and requests its host to adapt the iframe dimension to fit the new content.
  • [Theme](https://github.com/AmadeusITGroup/otter/blob/main/packages/%40ama-mfe/ng-utils/src/theme/: a host application requests its embedded module to apply a common css theme.

Messages are identified thanks to their type property and are versioned for backward compatibility.

Navigation messages

v1.0

Carries the target url only.

v1.1

Adds an optional extras field to forward a subset of Angular NavigationExtras across the iframe boundary so the receiving router can reproduce the original history/location semantics. Currently supports:

  • replaceUrl: when set, the host navigates by replacing the current history entry instead of pushing a new one. This is the key fix for modules that call router.navigate(..., { replaceUrl: true }) to skip a route from history — without forwarding, the host still pushes a new entry and the browser back button gets stuck in a loop.
