## FAQ
### How does `coc-go` compare to `vim-go`?
With `coc-go` I do not aim to recreate the features of `vim-go`. For now, the
main goal is to provide a convenient way to install `gopls` and use it with
`coc.nvim`.
If you need more than the features provided by `gopls`, you are probably better
of with [`vim-go`](https://github.com/fatih/vim-go) or
[`govim`](https://github.com/govim/govim).
### How to use `coc-go` with wasm?
Add this to you (local) `coc-settings.json` (run `:CocLocalConfig`).
```json
{
"go.goplsEnv": {
"GOOS": "js",
"GOARCH": "wasm",
}
}
```
### Running `gopls` as a daemon
`coc-go` runs `gopls` as shared daemon by passing `-remote=auto` to `gopls`. To
disable this behavior set `go.goplsUseDaemon` to `false`.
See [Running gopls as a daemon](https://github.com/golang/tools/blob/master/gopls/doc/daemon.md) for more information.
