Hi,
the solution would be:
1. Protect WASM source files with build flags so that when you open a
"backend" main sources, IDE won't complain about "syscall/js", like this:
// +build js,wasm
2. Open `wasm` directory in second instance of VS Code for which you would
set GOOS and GOARCH for a workspace. When editing settings in json, click
on "workspace" tab and VS Code will create .vscode/settings.json in `wasm`
directory. Put something like:
{
"go.toolsEnvVars": {
"GOOS": "js",
"GOARCH": "wasm",
}
}
in there.
3. In future, work in two instances of VS Code, even though if logically
it's a different parts of same project and could be under the same Go
module. All IDE features will work fluently. I haven't seen any problems
with this approach so far.
