Notes

Gopherjs compiles to js to run entirely in client browser unlike java nashorn or similar engine in jvm which allows running js code we dont hav that luxury, as a result the gatewayserver API and UI need to reside under same endpoint or else due to CORS https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS/Errors/CORSMissingAllowOrigin browsers won't allow connectivity between both. This also solves the problem of maintaining state for UI as its completely client side

Running in dev mode for testing

The easiest way to run the examples as WebAssembly is via wasmserve.

Install it (using Go 1.14+):

go get -u github.com/hajimehoshi/wasmserve

Then run an example:

cd trino-gateway/internal/frontend
wasmserve

Then navigate to http://localhost:8080/
