调试
electron-vite 支持调试主进程和渲染进程代码。
提示
当你通过 --outDir
CLI 参数自定义构建输出目录时,调试器配置也需要添加此参数。但通过配置文件的 build.outDir
进行自定义时则不需要这样做。
VSCode
添加文件 .vscode/launch.json
,配置内容为:
json
{
"version": "0.2.0",
"configurations": [
{
"name": "Debug Main Process",
"type": "node",
"request": "launch",
"cwd": "${workspaceRoot}",
"runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron-vite",
"windows": {
"runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron-vite.cmd"
},
"runtimeArgs": ["--sourcemap"],
"env": {
"REMOTE_DEBUGGING_PORT": "9222"
}
},
{
"name": "Debug Renderer Process",
"port": 9222,
"request": "attach",
"type": "chrome",
"webRoot": "${workspaceFolder}/src/renderer",
"timeout": 60000,
"presentation": {
"hidden": true
}
}
],
"compounds": [
{
"name": "Debug All",
"configurations": ["Debug Main Process", "Debug Renderer Process"],
"presentation": {
"order": 1
}
}
]
}
{
"version": "0.2.0",
"configurations": [
{
"name": "Debug Main Process",
"type": "node",
"request": "launch",
"cwd": "${workspaceRoot}",
"runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron-vite",
"windows": {
"runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron-vite.cmd"
},
"runtimeArgs": ["--sourcemap"],
"env": {
"REMOTE_DEBUGGING_PORT": "9222"
}
},
{
"name": "Debug Renderer Process",
"port": 9222,
"request": "attach",
"type": "chrome",
"webRoot": "${workspaceFolder}/src/renderer",
"timeout": 60000,
"presentation": {
"hidden": true
}
}
],
"compounds": [
{
"name": "Debug All",
"configurations": ["Debug Main Process", "Debug Renderer Process"],
"presentation": {
"order": 1
}
}
]
}
然后,在(主进程或渲染进程)源代码中设置一些断点。转到“调试”选项卡并确保选择“Debug All”,然后你可以按 F5 开始调试。
提示
你也可以选择 Debug Main Process
仅调试主进程。由于渲染进程只能通过附加方式调试,所以无法单独调试渲染进程。
WebStorm
创建 Npm
运行配置。使用以下设置进行主进程调试:
Setting | Value |
---|---|
Command | run |
Scripts | dev |
Arguments | -- --sourcemap --remote-debugging-port=9222 |
同时,创建一个 Attach to Node.js/Chrome
运行配置。使用以下设置进行渲染进程调试:
Setting | Value |
---|---|
Host | localhost |
Port | 9222 |
然后在调试模式下运行这些配置。
V8 Inspector, e.g. Chrome DevTools
electron-vite 还支持在没有 IDE 的情况下调试。可以使用以下命令之一启动 electron-vite。
sh
# Electron will listen for V8 inspector.
electron-vite --inspect --sourcemap
# Like --inspect but pauses execution on the first line of JavaScript.
electron-vite --inspect-brk --sourcemap
# Electron will listen for V8 inspector.
electron-vite --inspect --sourcemap
# Like --inspect but pauses execution on the first line of JavaScript.
electron-vite --inspect-brk --sourcemap
一旦 electron-vite 启动,你可以通过在浏览器上打开 chrome://inspect
并连接到 V8 inspector 来使用 Chrome DevTools
调试。
提示
如果你想调试源代码而不是打包后的代码,则应该附加 --sourcemap
选项。
