  skip app/components/my-component.js
  tip to add a class, run `ember generate component-class my-component`

Expected Behavior

Generating files should generate typescript files.

Current Behavior

Generated files have the .js extension.

By enabling the ENV flag EMBER_TYPESCRIPT_BLUEPRINTS=true i can generate the Typescript blueprints

EMBER_TYPESCRIPT_BLUEPRINTS=true ember g component example

Maybe i misunderstood the purpose of the flag in the .ember-cli file ?

Thank you in advance.

Hi @AmauryD, thanks for opening this issue. I've asked for more info about the env flag on Discord:
https://discord.com/channels/480462759797063690/485447409296736276/1014250847200358480

It seems the EMBER_TYPESCRIPT_BLUEPRINTS env flag serves as a "feature" flag, so people can experiment with the TypeScript blueprints without them being enabled by default. I realise now that this is a bit confusing since we also have the isTypeScriptProject option.

For now, I'm afraid you'll have to keep using the EMBER_TYPESCRIPT_BLUEPRINTS env flag. I will open a new issue in the ember-source repo (tomorrow) to get rid of the flag so that everything works as expected.

Going to close this one in favor of emberjs/ember.js#20177.

Thank you very much for the explanation ! 😄

@AmauryD FYI we have enabled the flag by default over in ember-source: emberjs/ember.js#20352
So should be available soon!
