node.js - Node Express App debugging with calls from separate client app using WebStorm -


i've looked around , had lot of trouble figuring out. i'm hoping might able point me post or have information on how this.

my problem have 2 projects i've made using webstorm:

  • i have 1 application server-side code running on port 3000. it's simple node express app.
  • the second application angular 4 / ionic 3 application running client side on port 8100.

i want run server application in debug mode, hits breakpoints data being sent client side app.

for example: angular / ionic app sends request clients given customer. customer sent via url parameter. want server code pause when receives request , can see url parameter. simple.

the server using grunt build project, , nodemon watch it. i'm using npm scripts make life easy. here scripts:

"scripts": {   "dev": "set node_env=development && nodemon ./bin/www",   "grunt": "grunt",   "start": "node ./bin/www" },

nothing fancy.

i have webstorm configured run scripts hitting play. play button first run following sequence:

  1. npm run grunt
  2. npm run dev

again ... nothing fancy.

now how thing setup debugger can listen in webstorm? have both projects open in separate windows, , initiating calls server client. how make break points grab hold , show me data coming server?

i feel incredibly easy , i'm missing stupid. appreciated.

you need starting server in debugger breakpoints in server code hit. if prefer start app via npm script, have add $node_debug_option (or %node_debug_option% on windows) make sure node.js started appropriate debug options (--debug-brk, --inspect-brk, etc)

so:

  • in package.json, modify dev script follows:

"dev": "set node_env=development && nodemon %node_debug_option% ./bin/www"

  • right-click package.json, choose show npm scripts
  • right-click dev script in npm tool window opens, choose edit 'dev' settings create run configuration.
  • open source files in editor, add breakpoints
  • press debug start debugging
  • run client app, initiate calls server
