Top level await support

[joshuanathanson]

Hi, I'm trying to migrate a TS/React project to Snowpack. I thought I'd start out with the blank template and use the built in TypeScript and JSX support out of the box.

I pretty much got a configuration that is working, however it's erroring out when it hits a top level await call:

await registerTriggers(metadataId, effectTriggers);

I get this error:

Unhandled Runtime Error
Uncaught SyntaxError: Unexpected reserved word

I'm wondering if there is not support for that yet, and if not, what might be a configuration set (plugins etc.) that would support that.

Thanks!

I did a little digging around, and it looks like this is an issue with the build tool that Snowpack uses internally. There is an open issue to support top level await, but ATM it looks like it just passes it through. So when this code lands in the browser, it throws an error, because top level await is not supported in the browser.

esbuild now has initial top level await support since version 10 but it seems snowpack 3.7.1 ships with [email protected]. Is there any plan to update?
