Chris Crichrycho (@chriskrycho) Wrote a blog post understanding args In the Glimmer component Focus on what happens when it happens Update to args.

Chris explained how the Glimmer component works when you remove all reactivity and only perform a single pass.This Low light component API Set up args Class in object constructor. This args The objects in the Glimmer component are also Read only Because it is a Private class field Simultaneous exposure to the getter.

class Component {
  #args: object;
  get args() {
    return this.#args;

  constructor(args: object) {
    this.#args = args;

The blog recommends never assigning from attributes args To the local class field in the Glimmer component, because changes to the parent are never reflected in the component. You should instead use the getter that is recalculated at call time.

Ember blog There is a new look and a new code base! The Ember blog was created 8 years ago, in 2012. It has been a custom Ruby application for many years, mainly for publishing blog posts. Today, the blog is the homepage of Ember Times, announcements, guest learning articles, etc., so a group of dedicated contributors set out to make some improvements. The blog is now an Ember application. At the bottom, it uses the same technology as the Ember guide. QueenThe Empress tool helps to convert Markdown to HTML in Ember applications, which means that you can write articles quickly using Markdown, and contributors can use all the excellent tools provided by Ember.

There is another great new product centered on Glimmer Blog post From Rajasegar Chandran (@rajasegar) About how to use Glimmer.js and single-spa to make a micro front end!

If you haven’t followed, Rajasegar has published many wonderful posts on dev.to, Many of which involve Glimmer.js.

This new article focuses on using Single Hot Spring Library Use Glimmer to build a micro front end.

Single-spa is a JavaScript router for front-end microservices that allows you to use multiple frameworks in a single-page application.For the integration with Glimmer, Rajasegar released a Single spa plugin This helps to inject multiple super fast Glimmer applications into a single page, which is impossible.

This setup is very experimental and cutting-edge, but it does show the flexibility of Glimmer and what you can do with it if you have a very specific use case.

Check out this great post and look for more great Glimmer content from Rajasegar in the future!
