Q: Better TypeScript support?

[jakobjs]

Are there any plans to better support TypeScript?

Why was the .ts extension dropped by the developers?

[antongolub]

It seems reasonable to extend zx + ts-node/tsc guide in future.

Zx dropped *.ts support as it requires CJS, and cjs was dropped as it was causing a lot of problems.

Since the .mjs extension is supported, it seems we can build/transpile TS to JS in a .mjs and just run that, right?

Are there any details required to do such a build to make a TS project (like in VSCode) fully compatible with zx?

The doc page on TypeScript is only vaguely helpful, as it doesn't actually mention TypeScript. 🤔

[antonmedv]

TS integration is possible. But requires some boilerplate.

[TonyGravagno]

OK, that's fair. It seems clear that "Better TypeScript Support" is a "wont fix" type resolution for this. Or, maybe the ticket should be modified into a request for new documentation with boilerplate for TS support?

As a newcomer, I see TS as a convenience but not a requirement. It would be nice to see TS support but I have no problem continuing with my research into zx without it.

Well, there is some progress:

• test: add ts smoke tests #801
• https://github.com/google/zx/pull/797/files#diff-20636ffeaae02af6484f79cee2950ccbafe715049cd492a16466670784d5bd21

We have expanded the documentation section dedicated to TS configuration: https://google.github.io/zx/typescript
Proven examples can also be found in the project tests.
