launch.json Configuration Guide

In Visual Studio Code (VSCode), launch.json is a crucial configuration file that helps you debug your code effectively. Within launch.json, you define the debugger's settings, such as the debugger type, program entry point, program arguments, and more. This flexibility simplifies the process of debugging your programs.

Using launch.json, you can achieve the following:

FeatureDescription
Local and Remote DebuggingConfigure both local and remote debugging for your code.
Multi-Language Debugging SupportConfigure debugging for various programming languages, such as Java, Python, Go, etc.
Debugging Parameter ConfigurationCustomize debugging parameters, including environment variables, working directories, and target files.
Setting BreakpointsSet breakpoints to pause execution, view code at specific points, and inspect the call stack.

Configuration Fields

Example for Golang in launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Launch test function",
      "type": "go",
      "request": "launch",
      "mode": "test",
      "program": "${workspaceFolder}",
      "args": [
        "-test.run",
      ],
      "cwd": "${workspaceFolder}"
    }
  ]
}

Field Descriptions

Field NameDescription
versionConfiguration file version (currently supports only "0.2.0").
configurationsAn array of configurations, each represented as an object.
nameConfiguration name displayed in the debugger.
typeDebugger type (e.g., go, python, java).
requestRequest type: "launch" starts the debugger, "attach" connects to a running program.
modeDebugging mode (e.g., test, exec, debug).
programProgram entry file (can be a file path or directory).
argsProgram arguments (can be an array or a string).
cwdWorking directory where the program runs.
envEnvironment variables provided as an object.
stopOnEntryIf true, stops at the entry point after startup, waiting for debugger connection.
preLaunchTaskSpecifies a task to run before debugging starts (usually a compilation task).
postDebugTaskSpecifies a task to run after debugging ends (e.g., cleanup tasks).
outFilesOutput file paths for mapping source code to compiled files.
sourceMapsControls whether to enable source code mapping ("inline," "both," or "false").
sourceMapPathOverridesAdjusts file paths based on source code mappings.
externalConsoleIf true, runs the program in an external console.
internalConsoleOptionsControls how the internal console is displayed: "neverOpen," "openOnSessionStart," or "openOnFirstSessionStart."
showAsyncStacksIf true, displays information about asynchronous calls in stack traces.
stopOnErrorIf true, pauses debugging on errors.
smartStepIf true, skips unnecessary code during debugging.
skipFilesSpecifies files or folders to exclude from debugging.
justMyCodeIf true, only debugs your own code.
