[DEP0062] node --debug and node --debug-brk are invalid

[jchook]

Hello, thanks for making delta-chat. When trying to set-up a local dev environment, I ran into an issue launching electron.

• Operating System (Linux/Mac/Windows/iOS/Android): Linux
• Delta Chat Version: master (v1.20.3)
• Expected behavior: Able to start electron with npm run start
• Actual behavior: Electron exits with a deprecation notice and status 9
• Steps to reproduce the problem:

1. Clone the project
2. npm ci to install dependencies
3. npm run start to launch electron
4. See that electron exits with status 9 and a deprecation notice

I can also reproduce by running the electron command manually:

electron . --debug --log-debug --log-to-console --disable-http-cache --translation-watch
echo $? # 9

• Screenshots:
• Logs:

electron: [DEP0062]: `node --debug` and `node --debug-brk` are invalid. Please use `node --inspect` and `node --inspect-brk` instead.

---

I temporarily solved the issue the issue by replacing the --debug flag from the start script in package.json with --inspect.

Separately I encountered this error, which prevented npm run watch from working:

> deltachat-desktop@1.20.3 watch:shared /home/jchook/forks/deltachat-desktop
> npm run watch:shared:translations

npm ERR! missing script: build:frontend:source_map_support
npm ERR!
npm ERR! Did you mean one of these?
npm ERR!     build:frontend:source-map-support
npm ERR!     build:frontend:themes
npm ERR!     build:frontend:scss

I fixed this by updating the script in package.json...

-     "watch:frontend": "npm run build:frontend:source_map_support && npm run watch:frontend:ts & npm run watch:frontend:static & npm run watch:frontend:scss",
+     "watch:frontend": "npm run build:frontend:source-map-support && npm run watch:frontend:ts & npm run watch:frontend:static & npm run watch:frontend:scss",

which node version did you use? we only tested with version 12.

[jchook]

I tried node 10, 12, and 14.

Looks like --debug and --debug-brk have been deprecated since Node v7.7.0.

Also I see Node uses exit status 9 to indicate invalid arguments.

Is this fixed?

[Simon-Laux]

strange, which version of electron are you using?
I don't get that error somehow.

Anyways, the --debug we use is not meant for node debugging but for triggering our debug logging (a shortcut for --log-debug & --log-to-console) maybe we should rename it if it conflicts with electron/node -arguments.
