# Debugging in VSCode
|
|
|
|
This guide goes over how to set up VSCode debugging for both your own Electron project as well as the native Electron codebase.
|
|
|
|
## Debugging your Electron app
|
|
|
|
### Main process
|
|
|
|
#### 1. Open an Electron project in VSCode.
|
|
|
|
```sh
|
|
$ git clone git@github.com:electron/electron-quick-start.git
|
|
$ code electron-quick-start
|
|
```
|
|
|
|
#### 2. Add a file `.vscode/launch.json` with the following configuration:
|
|
|
|
```json
|
|
{
|
|
"version": "0.2.0",
|
|
"configurations": [
|
|
{
|
|
"name": "Debug Main Process",
|
|
"type": "node",
|
|
"request": "launch",
|
|
"cwd": "${workspaceFolder}",
|
|
"runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron",
|
|
"windows": {
|
|
"runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron.cmd"
|
|
},
|
|
"args" : ["."],
|
|
"outputCapture": "std"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
#### 3. Debugging
|
|
|
|
Set some breakpoints in `main.js`, and start debugging in the [Debug View](https://code.visualstudio.com/docs/editor/debugging). You should be able to hit the breakpoints.
|
|
|
|
Here is a pre-configured project that you can download and directly debug in VSCode: https://github.com/octref/vscode-electron-debug/tree/master/electron-quick-start
|
|
|
|
## Debugging the Electron codebase
|
|
|
|
If you want to build Electron from source and modify the native Electron codebase, this section will help you in testing your modifications.
|
|
|
|
For those unsure where to acquire this code or how to build it, [Electron's Build Tools](https://github.com/electron/build-tools) automates and explains most of this process. If you wish to manually set up the environment, you can instead use these [build instructions](../development/build-instructions-gn.md).
|
|
|
|
### Windows (C++)
|
|
|
|
#### 1. Open an Electron project in VSCode.
|
|
|
|
```sh
|
|
$ git clone git@github.com:electron/electron-quick-start.git
|
|
$ code electron-quick-start
|
|
```
|
|
|
|
#### 2. Add a file `.vscode/launch.json` with the following configuration:
|
|
|
|
```json
|
|
{
|
|
"version": "0.2.0",
|
|
"configurations": [
|
|
{
|
|
"name": "(Windows) Launch",
|
|
"type": "cppvsdbg",
|
|
"request": "launch",
|
|
"program": "${workspaceFolder}\\out\\your-executable-location\\electron.exe",
|
|
"args": ["your-electron-project-path"],
|
|
"stopAtEntry": false,
|
|
"cwd": "${workspaceFolder}",
|
|
"environment": [
|
|
{"name": "ELECTRON_ENABLE_LOGGING", "value": "true"},
|
|
{"name": "ELECTRON_ENABLE_STACK_DUMPING", "value": "true"},
|
|
{"name": "ELECTRON_RUN_AS_NODE", "value": ""},
|
|
],
|
|
"externalConsole": false,
|
|
"sourceFileMap": {
|
|
"o:\\": "${workspaceFolder}",
|
|
},
|
|
},
|
|
]
|
|
}
|
|
```
|
|
|
|
**Configuration Notes**
|
|
|
|
* `cppvsdbg` requires the [built-in C/C++ extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools) be enabled.
|
|
* `${workspaceFolder}` is the full path to Chromium's `src` directory.
|
|
* `your-executable-location` will be one of the following depending on a few items:
|
|
* `Testing`: If you are using the default settings of [Electron's Build-Tools](https://github.com/electron/build-tools) or the default instructions when [building from source](../development/build-instructions-gn.md#building).
|
|
* `Release`: If you built a Release build rather than a Testing build.
|
|
* `your-directory-name`: If you modified this during your build process from the default, this will be whatever you specified.
|
|
* The `args` array string `"your-electron-project-path"` should be the absolute path to either the directory or `main.js` file of the Electron project you are using for testing. In this example, it should be your path to `electron-quick-start`.
|
|
|
|
#### 3. Debugging
|
|
|
|
Set some breakpoints in the .cc files of your choosing in the native Electron C++ code, and start debugging in the [Debug View](https://code.visualstudio.com/docs/editor/debugging).
