How can I debug Strapi project in WebStorm? (https://strapi.io/)
If you like to debug your controllers, etc., you have to start the server in debug mode, using node --inspect-brk ./node_modules/strapi/bin/strapi.js dev, like
and then open the corresponding URL in browser

I'm using .net core and ServiceStack Angular SPA project template, and I want to enable hot reloading.
From what I saw on site here I only need to add:
Plugins.Add(new TemplatePagesFeature());
<i hidden>{{ '/js/hot-loader.js' | ifDebugIncludeScript }}</i>
And:
SetConfig(new HostConfig
{
DebugMode = true
});
And this works for HTML files, however, nothing happens when I modify TS files (in console or browser), do I need to configure something else in order to allow that?
EDIT
I thought that this will also start something like npm run dev (to run --aot) but does not look like that, so my temporary solution until I find more elegant way is to use something like this and shell extension:
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.Shell("npm run dev");
}
The Development workflow for each template can be found on the project page for each template. E.g. the Angular SPA Project Template requires that you run either npm run dev or npm run serve which starts a watched client build:
Development workflow
Our recommendation during development is to run the dev npm script or Gulp task and leave it running in the background:
$ npm run dev
This initially generates a full development build of your Web App then stays running in the background to process files as they’re changed. This enables the normal dev workflow of running your ASP.NET Web App, saving changes locally which are then reloaded using ServiceStack’s built-in hot reloading. Alternatively hitting F5 will refresh the page and view the latest changes.
Each change updates the output dev resources so even if you stop the dev task your Web App remains in a working state that’s viewable when running the ASP.NET Web App.
Live reload with built-in Dev Server
The alternative dev workflow is to run the serve npm or gulp script to run Create React App's built-in Webpack dev server:
$ npm run serve
This launches the Webpack dev server listening at http://localhost:4200/ and configured to proxy all non-Webpack HTTP requests to the ASP.NET Web App where it handles all Server API requests. The benefit of viewing your App through the Webpack dev server is its built-in Live Reload feature where it will automatically reload the page as resources are updated.
Watched .NET Core builds
.NET Core projects can also benefit from Live Coding using dotnet watch which performs a “watched build” where it automatically stops, recompiles and restarts your .NET Core App when it detects source file changes. You can start a watched build from the command-line with:
$ dotnet watch run
I'm trying to debug my TypeScript Express app using WebStorm.
I have this debug script in package.json
"scripts": {
...
"debug": "node --inspect-brk=9229 --require ts-node/register -r tsconfig-paths/register server.ts"
}
I run npm run debug in the command line and the following loads
Debugger listening on ws://127.0.0.1:9229/<somerandomid>
For help see https://nodejs.org/en/docs/inspector
Now I am able to debug from Chrome inspector by going to Chrome, type in chrome://inspect/ and server.ts would appear in Remote Target, and I can debug the TypeScript by clicking inspect. Hence I know that the problem is not my node.js configuration side.
The problem is, I can't debug when using WebStorm.
I tried the following WebStorm debug configuration:
Attach to Node.js/Chrome
Host: localhost
Port: 9229
Attach to: Chrome or Node.js > 6.3 started with --inspect
but when I debug in WebStorm the debugger keeps on saying "Connecting to localhost:9229" and nothing happens. It doesn't go to breakpoints even though I have set breakpoints in server.ts etc
I tried disabling firewall, still doesn't work. Tried using --inspect instead of --inspect-brk, still doesn't work.
What am I doing wrong, and how can I get WebStorm to debug into breakpoints using my node.js Express TypeScript configuration?
Works fine for me using your way to start the app/attach the debugger. What WebStorm version do you use?
here are 2 other ways to debug your app:
using Node.js run configuration (create similar configuration and press Debug):
using NPM run configuration:
change your script to "debug": "node %NODE_DEBUG_OPTION% --require ts-node/register -r tsconfig-paths/register server.ts" (if you are on Linux/Mac OSX, replace %NODE_DEBUG_OPTION% with $NODE_DEBUG_OPTION
click the arrow in the gutter, choose Debug
I've started my application on my server with pm2:
pm2 start /path/lib/start-server.js --name="cdl-debug" -- --inspect
Which would be equivalent to node /path/lib/start-server.js --inspect
The application starts and runs, although I see no notice in the logs about any debugging like explained here
I've opened up port 9229 in the firewall and setup my WebStorm debug config with Attach to Node.js/Chrome like so:
Then when I run the debugger it tries to connect for a while and finally fails with the message: Connection timed out. No further information.
Is there something else I should do? The WebStorm documentation doesn't mention much about the required setup on the server.
When running node /path/lib/start-server.js --inspect, you are passing --inspect to your application, not to Node.js. As a result, debugger is not started. You need to make sure to pass --inspect-brk to Node.js in order to debug your app:
node --inspect-brk /path/lib/start-server.js
You can specify --inspect-brk in your pm2 process.json, like
"node_args": [
"--inspect-brk=7000"
]
and then start your app with pm2 start process.json
I've looked around and had a lot of trouble figuring this out. I'm hoping someone might be able to point me to a post or have information on how to do this.
My problem is that I have 2 projects I've made using WebStorm:
I have 1 application that is my server-side code running on port 3000. It's a simple Node Express app.
The second application is an Angular 4 / Ionic 3 application running the client side on port 8100.
I want to run my server application in debug mode, so that it hits the breakpoints for all the data being sent from the client side app.
For example: Angular / Ionic app sends a get request for all clients for a given customer. The customer is sent via url parameter. I want the server code to pause when it receives this request and so I can see this URL parameter. Fairly simple.
The server is also using grunt to build the project, and nodemon to watch it. I'm using some npm scripts to make life easy. Here are the scripts:
"scripts": {
"dev": "SET NODE_ENV=development && nodemon ./bin/www",
"grunt": "grunt",
"start": "node ./bin/www"
},
Nothing fancy.
I have WebStorm configured to run my scripts from hitting play. So the play button will first run the following sequence:
npm run grunt
npm run dev
Again ... nothing fancy.
Now how do I get this thing to setup a debugger so I can listen in WebStorm? I have a both projects open in separate windows, and I am initiating the calls to the server from the client. How do I make the break points grab hold and show me the data coming into the server?
I feel like this is incredibly easy and I'm missing something really stupid. Any help would be much appreciated.
You need starting you server in debugger to get breakpoints in your server code hit. If you prefer to start your app via npm script, you have to add $NODE_DEBUG_OPTION (or %NODE_DEBUG_OPTION% on Windows) to make sure that Node.js is started with appropriate debug options (--debug-brk, --inspect-brk, etc)
So:
in package.json, modify your dev script as follows:
"dev": "SET NODE_ENV=development && nodemon %NODE_DEBUG_OPTION% ./bin/www"
right-click your package.json, choose Show npm scripts
right-click dev script in npm tool window that opens, choose edit 'dev' settings to create a run configuration.
open your source files in editor, add breakpoints
press Debug to start debugging
run your client app, initiate the calls to the server
I am working on a nodejs project. I am thinking, is it possible to debug nodejs code like the way debug JavaScript in browser. I mean is there any tool or plugin available to debug nodejs.
https://github.com/node-inspector/node-inspector
^You can use node-inspector for debugging.
1) Start your node process in debug mode,
"node --debug-brk=5858 app.js"
2) Start node-inspector process with,
"nohup node-inspector &"
3) In your browser, go to:
http://127.0.0.1:9001/debug?port=5858
and start debugging.
