"port": 9229,
"cwd": "${workspaceFolder}/frontend",
"sourceMapPathOverrides": {
"webpack:///./*": "${workspaceRoot}/frontend/*"
}
}
]
}
code for my.next.config.js
module.exports = {
webpack(config) {
config.devtool = 'cheap-module-eval-source-map'
return config
},
}

note: I am completely newbie in Next.Js it is might possible i have done messed in folder structure or in code. your valuable help will be appreciated, thanks in advance
Next.js Docs has its dedicated documentation over Debugging.
Your .vscode/launch.json
should be:
{
"version": "0.2.0",
"configurations": [
{
"name": "Next.js: debug server-side",
"type": "node-terminal",
"request": "launch",
"command": "npm run dev"
},
{
"name": "Next.js: debug client-side",
"type": "pwa-chrome",
"request": "launch",
"url": "http://localhost:3000"
},
{
"name": "Next.js: debug full stack",
"type": "node-terminal",
"request": "launch",
"command": "npm run dev",
"console": "integratedTerminal",
"serverReadyAction": {
"pattern": "started server on .+, url: (https?://.+)",
"uriFormat": "%s",
"action": "debugWithChrome"
}
}
]
}
And no changes should be made with
next.config.js
.
npm run dev
can be replaced with yarn dev
if you're using Yarn. If you're changing the port number your application starts on, replace the 3000
in http://localhost:3000
with the port you're using instead.
You can select the type of debugging option you need from the dropdown.
Finally found solution, I have edited my launch.json in following way and everything is working as expected, thank you for your valuable time guys.
launch.json
{
"configurations": [
{
"name": "Launch Chrome",
"request": "launch",
"type": "pwa-chrome",
"url": "http://localhost:3000",
"webRoot": "${workspaceFolder}/frontend"
},
{
"name": "Attach to Edge",
"port": 9222,
"request": "attach",
"type": "pwa-msedge",
"webRoot": "${workspaceFolder}/frontend"
},
{
"type": "chrome",
"request": "launch",
"name": "Launch Chrome against localhost",
"url": "http://localhost:3000",
"webRoot": "${workspaceFolder}"
},
{
"name": "Launch Edge",
"request": "launch",
"type": "pwa-msedge",
"url": "http://localhost:3000",
"webRoot": "${workspaceFolder}/frontend"
},
{
"name": "Launch Microsoft Edge and open the Edge DevTools",
"request": "launch",
"type": "vscode-edge-devtools.debug",
"url": "http://localhost:3000" // Provide your project's url to finish configuring
}
]
