Is this by design.

Local blueprint is used in project that can be type commonjs.
Generators are type module, we need to use mjs extension or add a package.json with type module in .blueprint dir.

Non local blueprints are packages that we generate as type module. So it can have js extension. js is the preferred extension so we use it.

[mshima]

If you prefer mjs extension you can use --no-js option.
Since js is the default now, would make sense to convert to --mjs.

makes sense, thank you @mshima. Is there any plan in the future to convert the blueprints to typescript.

[mshima]

No plans for typescript blueprints in official blueprints and generate-blueprint command.
I don’t see any advantage in adding the typescript complexity in blueprints.
But it’s possible to create a typescript blueprint.

[mshima]

We should add an option extension with 'js' and 'mjs' options, which will default to 'mjs' for local blueprint and 'js' otherwise.
