Known Limitations

Ember-Specific

Glint is not currently integrated with ember-cli-typescript, so typechecking performed during an ember-cli build will not take templates into account.

In addition, the template registry must currently be maintained by hand. A few possibilities for mitigating that pain have been discussed, but ultimately the best solution will be when strict mode comes to Ember and we no longer need to reckon with runtime resolution of template entities.

Tooling

In VS Code, you will see diagnostics from both TypeScript and Glint in many files, as well as false 'unused symbol' positives for things only referenced in templates. See the VS Code extension README for details on dealing with this.
