Debugging Go App on VS Code using Delve Debugger

Background

We are using Go lang for few of our project and we struggled in debugging application using open source/free tools.
And finally succeeded using delve + go + vs-code

Tools we will be using
- VS-Code
- delve
- Mac Book M2

Step1: Installing delve

Installation is pretty straightforward as listed below

$ git clone https://github.com/go-delve/delve
$ cd delve
$ go install github.com/go-delve/delve/cmd/dlv

And follow steps outlined here

Step2: Verifying installation

Step3: Creating launch json

To create a launch.json file, select create a launch.json file in the Run start view

fig2: launch.json

fig3: launch.json

Step4: Providing parameter to the project

Most of the enterprises application will have good amount of parameters to start the application.
What we can do is create a XXX.env file and provide that location in launch.json using envFile tag.

Step5: Running the application

Go to menu Run -> Start Debugging to start the debug session below pop up will appear allow and debug the application.

Happy Debugging Go app.
