TypeSpec: 0.67.1
Repo steps
- install TypeSpec extension in VS Code
- click "Create TypeSpec Project" and select the template "Generic REST API"
I found it will list all available emitters for optional install.

Listing all available code emitters here is confusing. "Generic REST API" shows the purpose of setting up an API definition. Emitter libraries can be prompted to install when users choose "Emit from TypeSpec".
