TypeScript bundling should generate compile errors

[OliverJAsh]

It is my understanding that transpiling TypeScript (in the browser) does not generate compile errors (when there are any).

When bundling we should do a whole compile (different from a transpile), which will generate compile errors. Currently we transpile in the browser and when bundling.

See microsoft/TypeScript#2233 (comment).

So is there any ETA for this?

This would be wonderful!

FYI - I have added type-checking support to plugin-typescript so you are welcome to give that a try. You will need to use version 2.0.0-beta.

There is an example project there showing the configuration, and if you have any issues then please raise them on that repo. It is pretty much feature complete, I have a couple of tasks left to look at the performance/caching when run as a watch task.

This is also related to systemjs/systemjs#595 for ensuring that helper code is not included within the System.register wrapper.

@vladima let me know if there is anything we can do here - currently syntax errors don't seem to give any warnings when compiling with TypeScript.

By the sounds of jspm/jspm-cli#1009 (comment), this is by design?

The current focus for TypeScript support is via https://github.com/frankwallis/plugin-typescript which I believe gives better errors too.
