This is awesome, we need to figure out what breaking changes (if any) occurred in 0.7.0, then we are good to go!
PRs welcome!

Hmmmm, this might be a big problem for us... 🤔

Is this possible?
SourceMapConsumernow returns aPromise, but catching and mapping thrown exceptions needs to be synchronous.SimenB commentedon Mar 18, 2018
Jest is also unable to upgrade due to the lack of a sync API, FWIW
niieani commentedon Apr 28, 2018
@SimenB Could deasync help here? It hooks into Node's event loop and essentially makes any async operation a sync one.

I published https://www.npmjs.com/package/@snek/source-map-support which works nicely in node and may work in browsers that allow you to load reasonable sized wasms synchronously. It wraps the 0.8.0-beta.0 release of source-map.

@andreicristianpetcu
@devsnek there is no case for async source map consumer other than problems of specific ill-thought implementation by Mozilla.
Like: await in stack trace handler? Are they nuts?

@cspotcode/source-map-supportuses@cspotcode/source-map-consumerwhich is a fork ofsource-mapthat only has the consumer.@cspotcode/source-mapincludes the generator, too.These are based on the latest
source-mapversion. They use WASM and have a sync API.You might have luck giving them a try. It's all open-source, so of course the changes can be ported over.

This will also fix an annoying issue in VS Code.
source-map@<0.7.1 has an invalid
typingsfield in itspackage.jsonwhich is causing VS Code to report an error that it can't find the type declarations. This is fixed in source-map@>=0.7.1.SimenB commentedon Apr 20, 2022
Babel has migrated to https://npmjs.com/package/@jridgewell/trace-mapping, should this module as well? Code change seems fairly trivial (no idea about browser support, but probably?)

Jest and C8 (via
v8-to-istanbul) has also migrated, fwiwcspotcode commentedon Apr 20, 2022
I can migrate @cspotcode/source-map-support as well.
Would be nice to consolidate the ecosystem a bit more.
