TL;DR

If you are using Glimmer.js v1 in production like me, you can find this npm package which I published, useful. Its original repo is archived, so I forked and started maintaining separate npm package. For now, I only did one change to use the latest TypeScript features with Glimmer.js v1

What is Glimmer.js

Glimmer.js is a lightweight frontend tool like Preact to build components.

Why we are using it?

• We had a requirement to convert an Ember.js component to web component so it can be used in other apps, no matter what Frontend tooling other apps are using.
• Ember.js is a heavy framework used to build big applications. We needed this component to be lightweight.
• Glimmer.js was created for this purpose only, to build lightweight components, and it was also having a library to convert Glimmer.js components to browser web components

Challenges with Glimmer.js

• Glimmer.js team is working on v2 which is still in beta. And v1 is no longer maintained
• So in the project we are not able to use the latest TypeScript features, and use the latest JS features like dynamic importing. It is also not having code splitting.

Moving ahead

• I want to migrate this component to Stencil.js , which we are using for new web components which we are building, but it will take too much effort.
• So we will wait for v2 to get stable. Till that time, I will try to keep Glimmer.js supporting repositories up to date.
• I created fork of its pipeline component
• Also we are using redux with that component. For that using this fork
