Onivim supports the vscode-go extension:

Several language integration features are supported, like:

Recommended configuration
The vscode-go extension supports various toolchains, but we recommend using the gopls language server:
- Run
go get golang.org/x/tools/gopls@latest - Set
"go.useLanguageServer": truein your configuration.
