Install Bazel for Golang build applications in VScode

How to install bazel for golang application building in VScode?

There is no direct support for Bazel yet, as per golang/go issue 37205 ("x/tools/gopls: support for bazel-based projects")

bazelbuild/rules_go wiki/Editor-and-tool-integration has a design document for building editor and tool integration: a new gopackagesdriver binary that integrates Bazel+rules_go with golang.org/x/tools/go/packages.
But it is not fully implemented yet (Q1 2022).

In the meantime, you can follow Bazel IDE setup, which involves:

• Create a launcher script, say tools/gopackagesdriver.sh:

#!/usr/bin/env bash
exec bazel run -- @io_bazel_rules_go//go/tools/gopackagesdriver "${@}"

• adding in the .vscode/settings.json of your workspace:

{
  "go.goroot": "${workspaceFolder}/bazel-${workspaceFolderBasename}/external/go_sdk",
  "go.toolsEnvVars": {
    "GOPACKAGESDRIVER": "${workspaceFolder}/tools/gopackagesdriver.sh"
  },

    "references": false,
    "runtest": false
  },
