go get -u github.com/derekparker/delve/cmd/dlv


2. setup launch.json in vscode like this

"version": "0.2.0",
"configurations": [
{
"name": "Go debug",
"type": "go",
"request": "launch",
"mode": "debug",
"remotePath": "",
"port": 2345,
"host": "127.0.0.1",
"program": "${workspaceRoot}",
"env": {},
"args": [],
