Building a WASM executable

[alephnull]

When trying to build,

% GOOS=js GOARCH=wasm go build -o g.wasm
# github.com/spf13/viper
/home/alok/go/pkg/mod/github.com/spf13/viper@v1.7.0/viper.go:344:19: undefined: fsnotify.NewWatcher
/home/alok/go/pkg/mod/github.com/spf13/viper@v1.7.0/viper.go:366:20: select case must be receive, send or assign recv
/home/alok/go/pkg/mod/github.com/spf13/viper@v1.7.0/viper.go:393:18: select case must be receive, send or assign recv

For other packages, it was simple enough to exclude them from wasm builds with build tags but viper is all over the packages I need. Is there a way to use viper for WASM?

I guess we could make the watch functionality non-functional on WASM if it doesn't work anyway. We can do that with some build flags.

Looks like it's been already reported in #1071 (let's track it there)
