It looks like some support for this lives in the GlimmerJS repo, and a new standalone wrapper could probably be written to hack this together. There isn't currently a thin API to render Ember or Glimmer components by themselves. Missing API to mount / unmount Ember components

The current initialization code would need to be handled by the consumer so that the component could be initialized and destroyed when the parent component is unmounting, potentially multiple times within the lifetime of the parent app. The selector for the containing element div is specified at build-time, and the emitted output from ember build contains statements to initialize the app and render it on the page as soon as the bundle finishes parsing. Optionally in the future, these old components can be removed entirely, and the transition to fully Ember components is complete.Įmbedding Ember applications is already documented, but the current approach has a few limitations. As the new app grows in size, 'legacy' components can coexist with newer Ember components, and older components ported over one at a time. The consuming app (React in this case) has a different component model, but it can still seamlessly mount and unmount Ember components and pass data to them. Note that these initial component arguments will only be used for the first render of the Ember component - synchronizing state updates between the parent app and the Ember app left as an exercise for the reader (message passing could be used in this case). This is very similar to the design of ReactDOM.render, but also accepts initial component arguments for the root Ember component. The mount method takes in a reference to the component to be rendered (which it will handle initializing), a DOM node, and a set of initial component arguments. TinyEmber in this example is a fake library that provides a thin API over Ember itself. A few great examples of this are adding type checking with ember-cli-typescript, generating thin wrappers for ES modules with ember-auto-import, or even transforming imports from module syntax import Because the CLI tooling and the framework are deeply integrated, addons can be developed that make modifications to the build process.

This post aims to solve these pain points so that teams are free to progressively ship Ember components in their apps and migrate the application over time.Įmber applications are built and packaged with the ember-cli tooling. Teams might choose not to adopt Ember because they can't afford a several month feature freeze to port components over. However, because the app uses a client-side router, there needs to be a mechanism to load the Ember app and render into a div without resorting to an iframe. However, the team has heard about the many tooling improvements to Ember and wants to experiment shipping a small component in this existing React app. There's already support for pulling in ES modules and rolling them into the production bundle.

But what story do we tell for existing apps that are looking to transition to Ember?Ĭonsider a single page application that started in 2016 that uses React and webpack. Ember is great for brand new web applications. We have successfully refactored existing projects from async to sync without much trouble.In this post I'm proposing some improvements for Ember in an important, but often overlooked use case: embedding Ember components in non-Ember applications. Mixing sync and async can surprise developers in exactly the same ways we were trying avoid by using only sync relationships in the first place. We've found that sync relationships work best when you're able to use them for every relationship in your project (Storefront actually has an option to enforce this). There are some more goodies in there like run-time development assertions, so be sure to check back on it regularly as we continue to develop it. With sync relationships, this CP always works. In this post I'll outline why we think using relationships we would've needed to be aware of calls to this.get('comments') and comment.get('author') returning promise proxies. If you've spent any time around Sam and me, you've probably heard us talk about our frustrations with Ember Data's async relationships.
