vuejs3 debugging on Visual Studio Code not working

Asked 2021-Jun-12 at 15:19

I have recently moved over to Vuejs3 and my debugging setup stopped working. The breakpoints don't get triggered. I am using the same config files as before and not sure if something changed with this release.

Debugger for Chrome Extension: v4.12.12
VsCode: 1.56.2
Vue CLI v3
Platform: Ubuntu 20.04.2 LTS

launch.json

ANSWER

Answered 2021-Jun-07 at 20:46

I was in similar situation and couldn't find relevant resolutions:

Quick Answer: After upgrade to VS Code 1.56.2, make sure to remove old breakpoints and create new breakpoint and at-least have 1 breakpoint and launch.json available.

Lengthy details:

I have similar issue for python scripts when I start the "debugger bar" I see it for a couple of seconds the top debugging bar and then it disappears. Bu then no message on the console, nothing. I tried reinstalling VS Code, enabling/disabling extension, various restart.

OS and Version: Mac OSX Version 11.4 (20F71)
VS Code Version: 1.56.2
Extension: Python v2021.5.842923320 by Microsoft

RootCause:

What I did know for sure that I updated my VS Code, and after that this mysterious issue start happening, so when to release log of VS Code 1.56.2. I found below release log

Debug view displayed on break#

The default value of the debug.openDebug setting is now openOnDebugBreak so that on every breakpoint hit, VS Code will open the Debug view. The Debug view is also displayed on first session start.

So VS code Version 1.56 release, debugger will only show when at-least 1 breakpoint is found. However, looks like there is issue with their internal code checking for historical breakpoint data after VS Code upgrade..

How to automatic restart node application with nodejs and typescript?

Asked 2021-Jun-12 at 14:39

I'm setting up a new project with nodejs, express, typescript, and babel. So I use babel for faster transpile typescript code and etsc for types checking

When I writing code, I'd like to the application applied changes automatically without me manually restart the application. My solution is running babel cli for transpile code with nodemon. My script is like this

ANSWER

Answered 2021-Jun-12 at 14:39

The first problem is nodemon runs only babel command and not your ./dist/src/index.js. And the second problem is babel being run transpiles your .ts files into .js and then nodemon notices .js files changed and reruns your command (babel) that again transpiles your .ts files into .js ones with new timestamps. And I believe you've got the idea. So in fact you need two serapate but dependent things: recompile your .ts files into .js ones, and restart node only when .js files changed. You may achive that with something like that:

Error: Cannot find module 'babel-preset-react' - If you want to resolve "react", use "module:react"

Asked 2021-Jun-03 at 21:03

I have gone through all the SO questions regarding this issue and so far I haven't been able to fix this problem.

I am following a Pluralsight course on React and the example application is built manually from scratch; that means that each dependency is added manually without the use of any CLI. Since the course is somewhat old I had to spend quite some time upgrading most of babel's packages until I got to this problem when running webpack.

This is the list of dependencies on the package.json

ANSWER

Answered 2021-Jun-03 at 21:03

The babel key in your package.json is for Babel 6.x and references plugins that you do not have installed, which is why you are getting that error.

@babel/preset-env and @babel/preset-react will accomplish likely everything you need to worry about, so as long as those are installed and referenced in the Webpack config, you're good to go.

Visual Studio React Typescript webpack-dev-server hot reload not working for component changes

Asked 2021-May-30 at 10:47

I am using .Net Core 3.1 with React, Typescript and webpack for an SPA. I have multiple modules in react which I load on different page/view of Asp.Net core application.

I am facing issue with auto refresh or hot reload. When I change a parameter which I am passing from module to a component hot reload works as expected BUT if I do any change in component then those are not getting reflected in browser.

If I browse https://localhost:5010/webpack-dev-server I can see home.bundle.js there. Also if change value of "msg" param/prop of HomeComponent in HomeModule.tsx, I can see new bundle generated for home.bundle.js with fresh hashcode and change also reflects to browser on https://localhost:5010/home/ BUT If I do change to HomeComponent.tsx ex: if I change "Home component" to "Home component 123" this change not getting reflected neither on https://localhost:5010/home nor the new bundle NOT generating on https://localhost:5010/webpack-dev-server.

Here is my project structure and files including configuration files. Any help will be highly appreciated.

Update: I added HotModuleReplacementPlugin to webpack.dev.config.js and now when I modify something in component HomeComponent.tsx I see a new entry in https://localhost:5010/webpack-dev-server something like "5f80de77a97d48407bd9.hot-update.json". If I open this file it's content is like {"h":"0dce1f9e44bff4d47fb4","c":{}}

Apart from this another issue is when I run application with F5 from Visual Studio it takes couple of seconds to load website until than browser shows "This site can't be reached"
