FAQ

What files are emitted?

Outputs files are similar to the tsc cli in build mode. Meaning .js and .d.ts files will be output (depending on your project config). Beyond that .marko files with their types stripped and an associated .d.marko file will be output that serve a similar purpose to the .js and .d.ts files.

What is a .d.marko file?

A .d.marko files is similar to a .d.ts file. All script content in the file will be processed as if the Marko script-lang was typescript and the Marko-VSCode plugin and this CLI will both prefer loading a .d.marko over an adjacent .marko file. The .d.marko files output by this tool will strip out any runtime code such that only type information is in the .d.marko output.

Does this replace tsc?

Yes this replaces tsc since in order to provide proper type checking for .marko files the .ts and .js files must be processed as well.
