Asked by eckardritter
I am new to NodeJS and I have a droplet edshare.tech
Editing the helpText with the shark gif works but I cannot see a console output.
On Chrome I get: “DevTools failed to load SourceMap: Could not load content for chrome-extension://fehcbmngdgagfalpnfphdhojfdcoblgc/static/js/contentScript.js.map: HTTP error: status code 404, net::ERR_UNKNOWN_URL_SCHEME”
On Firefox: Error: Can’t find profile directory.
Restarting the hello app with pm2 is fine. I do it with the console of WinSCP
I need some tutorial or example for these very first steps to running a hello world app, adding some code and test it. Could someone help me?
Some more specific questions
- what is to be done with this 3000 port?
- I can cd in all directories. But how can I run apps in these directories?
- How can I use, for instance, index.js instead of hello.js - where is the attribution of apps to paths?
- Next step after “hello world”: the Airtable API
- Any configuration required for Nginx
- Suitable hello world examples on Github?
- Better alternative to WinSCP (working on Windows)
- Sometimes the WinSCP console says I need an interactive authorization or sudo. What is the easiest way to use the full range of commands?
Any hint would help! <3

Hi there @eckard.ritter,
I believe that a great resource for learning Node.js is this free eBook here:
How To Code in Node.js eBook
Regarding your questions:
https://www.digitalocean.com/community/tutorials/how-to-set-up-a-node-js-application-for-production-on-ubuntu-16-04
You can start an app from any directory as long as your project is stored in there
Here is a link to a Hello World project on GitHub that also uses index.js:

In case that you get an unauthorized message in WinSCP you need to use the command line and add the
sudokeyword in front of your command.Here are a couple of alternative terminals for Windows:

Hope that this helps. Regards, Bobby
