Core Features & Use Cases

  • Validates component args against the Signature Args interface.
  • Enforces Blocks and Yields typings for template blocks.
  • Checks Element typings for ...attributes compatibility.
  • Provides IDE autocomplete and inline error reporting via the tsserver plugin.
  • CLI type-checking with ember-tsc --noEmit for projects.
  • Supports registry augmentation for addons that ship Glint types.

Quick Start

Install Glint packages and run ember-tsc --noEmit to type-check all GTS templates in your Ember project.
