Vuejs - Breakpoints not set in VSCODE

Question

I'm trying to debug vuejs using vscode, I've tried a lot of tutorials/answers but can't get it to work.

So I decided to ask a question here, maybe there is a correct way to make it work now.

I created a project identical to the one I want to debug so I can post the print here.

The project structure is:

This is an unbound breakpoint:

The Sources tab in Chrome looks like this:

More detailed Chrome source tab:

vue.config.js：

/**
 * @type {import('@vue/cli-service').ProjectOptions}
 */
module.exports = {
  configureWebpack: {
    devtool: "source-map"
  },
  transpileDependencies: true
}

launch.json：

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "chrome",

            "webRoot": "${workspaceFolder}",
            "sourceMapPathOverrides": {
              "**/src/*": "${webRoot}/src/*",
            },
            "preLaunchTask": "vuejs: start"
          }
    ]
}

@A.D asked me if I tried using keywords

debugger;

The results are as follows: Ps: I don't want to start writing a debugger in my code...

But I can see the debugger file pointing to:

C:UsersvinicDesktoptesttestjswebpack:testsrccomponentsHelloWorld.vue

But the component src is actually located in

C:UsersvinicDesktoptesttestsrccomponentsHelloWorld.vue

Why do my breakpoints have no boundaries?

Answer 1

Try changing the webRoot parameter and keep the content in the document, you need to include src after ${workspaceFolder}.

{
  "type": "chrome",
  "request": "launch",
  "name": "vuejs: chrome",
  "url": "http://localhost:8080",
  "webRoot": "${workspaceFolder}/src",
  "breakOnLoad": true,
  "sourceMapPathOverrides": {
    "webpack:///src/*": "${webRoot}/*"
  }
}

renew: After some research, I found this question. There is a change in the version you are using. They changed the compiler and this affected the way the debugger behaved.

You can use "2.6.11" works in this version.

Note: This change affects subsequent releases.

Answer 2

It seems that vue 2.6.11 or above version of webpack has some problems

After some discussion with @Tonielton Mota, I noticed that if I completely remove the property names from package.json and package-lock.json, it works.

The following is the file that is running:
