Run Go code, using web assembly, in a React app that uses typescript. This is the minimum proof of concept that I could get working.
yarn build
yarn start
You can run go code. That's pretty cool, and lets you port your go applications really easily using the web.
You can call that Go code from Javascript.
You can do things to JS from Go Code. Small example of an alert
When you are done using a function and it will never be called again, you have to call Func.Release or the memory won't be freed up
Funcs can deadlock really easily, apparently - See this
The LoadWasm component and wasm_exec.js is just a huge bundle of boilerplate
Type safety in Go when crossing the JS bridge is annihilated. Go can't ensure anything about what is coming across that bridge, so the only args that can be used when defining bridge functions are []js.Value. There are a lot of methods on js.Value (.IsNumber, IsUndefined, etc.) to help you with this, but there is going to be a lot of conversion on your part.
The best way to handle this seems to just be minimizing what you pass back-and-forth between go and js, for the most part. This should be entirely possible - if you've worked with React Native and native modules, it should be a similar feeling.
Threads don't seem to really exist in the go implementation? Based on golang/go#28631 and https://news.ycombinator.com/item?id=30357078, it might be doable, but I really don't know.
