Parcel: Can It Support Typescript?

As My Title If It Support Typescript How To Config It

[DeMoorJasper]

It supports typescript, no need to config anything though.
Just point it to a index.html or whatever html file that has a script tag containing the typescript entrypoint and everything should work automagically

[DanielRuf]

Or directly at the index.js or is a .html file always required?

[DeMoorJasper]

It can also be a js file or pointing it directly at a Typescript file also works

[DanielRuf]

Right, because this also worked for me as our projects are not included in an index.html document at compile time.

I am not sure if it was mentioned in the docs / get startet that the given entry file can be also one of the many supported ecmascript subsets.

Just saw the example with the index.html.

I've created minimum typescript example.

@jimmycarry if these answers resolved your question, could you close the issue?

[jimmycarry]

@DeMoorJasper OK

Seems like one needs to rename the file from *.ts to *.tsx to support the JSX syntax? Otherwise parcel will complain " Unterminated regular expression" for the first encountered JSX tag.

I tried converting nodejs to parcel for this and dist folder just skipped ts files.

PS: didn't target ts files

For the record, while ParcelJS technically supports TypeScript, it ignores all errors in your code. This is a big deal for (at least some) TypeScript users. If you want errors, you need to use a plugin, but that also didn't work out for us due to a bug in that plugin. I personally wouldn't recommend it for TypeScript projects at this time, as impressive as the build times are.

I suppose using VSCode is good enough to identifying type errors. I belief typescript itself doesn't actually stop compilation on type error.

It doesn't work without configuration if you want to use react and TS
