Hello! I noticed a glaring omission in the Hello World example in Chapter 3!

It says:
Now to run our application, we type node src/index.js in our terminal. After doing so, we should see a log in our terminal that reads Listening on port 4000!. If that’s the case, open a browser window to http://localhost:4000 and we should see the following:
but never mentions the need to run npm install in order to dependencies (i.e. express) - somebody with zero Node,js experience would not "know" to do that and would be instantly derailed at the very first example! :heart:

Hi ! Thanks for your comment - this seems to be a frequent point of confusion for folks. I intentionally use a starter project, so that readers would not need to npm install dependencies themselves (and so that I could ensure consistent versions between myself and the reader). Unfortunately, I don't think I made that very clear. I'll be adding a note to the start of each major section (API, web, desktop, mobile) to try to clarify.

Ack! I was doing a final pass through of the book before handing it over to O'Reilly and I noticed that I had completely neglected to include npm install with the code cloning instructions. That has been fixed as well as adding an explanatory call out. Thanks again!

You're welcome! Would you like me to share other issues/typos/etc. or did you already Send It? :)

Everything has been through a couple of rounds of edits and technical reviews (though I did miss the npm install thing), so I am hopeful that it should be in good shape. None of those updates are on Safari just yet though. I'm doing a final careful pass through this week. If you do notice anything glaring, feel free to shoot me an email at [email protected], but hopefully all (or most!) errors should already be addressed. I'll also ping the folks at O'Reilly to see if they can push the updates to the first few chapters to Safari

I think this is happening to me as I followed the instructions and my terminal is throwing an error and I'm on this example

(adamdscott) that was actually another issue I resolved, this one I am stuck on still.
4:19pm
(ejflower98) what error are you getting? :)
5:52pm

I hope its something simple
5:59pm
(ejflower98) and you ran npm install etc.?

That would be my suggestion as well. Be sure to run npm install from the root of the project directory. Please let me know if you are still experiencing an issue
9:05pm
yeah I believe so but I don't know that much about node or anything since I'm a beginner... I could screenshare so you can see

(ejflower98) I suspect that this may be similar to the issue discussed in https://spectrum.chat/thread/ff2dad50-e5bd-4654-93df-2b84eb63ccb0?m=MTYyNTA2Nzg3MDQxMw==
Be sure to cd into the root directory of the project and then run npm install
