For anyone out there having problems with the styles not loading for the "/about/create" path, make sure you link your css to the html file as "/styles.css" and not "styles.css", otherwise it doesn't work. When you automatically create a link tag with VSCode by typing "link:css", VSCode doesn't add the slash at the beginning, so you might miss that.

Hi! Do I need to install Nodemon, Ejs, and other third party packages every time I start a project?
@leonelgauna1174
@leonelgauna1174 3 года назад
@@ahmedlabeeb2969 It depends on the project. I don't know what you want to build. Depending on the ideas you have, your project might need many third party packages, or none. Nodemon is good to have because it keeps track of the changes you make to your code and automatically restarts the server, that way you don't have to be constantly shutting down and turning on the server every time you change a line of code. Does a project need it to work? No, but it sure is helpful. EJS is a view engine that allows you to do server-side rendering. Basically you build your html on the server and then send it to the client's browser. It also gives you many features to build your pages. You can check its documentation to learn more. Again, the only one who knows what packages your project needs, it's you :).

Pretty often, for a French guy like me, we can be pretty afraid of programming jargon. When we speak about some terms like "Middleware", we think about something very technical, until someone explain that it's a simple/useful concept to apply. In any case, thank you for all the stuff you vulgarize. About view engine and static file (for CSS), I was already looking for clues/solutions by myself, so I didn't really need this new information. Even if I was pretty rough in my last comment, it was because I preferred something cleaner (Liquid) for my view engine than what you proposed.

@fikilekentane6982
@fikilekentane6982 3 года назад
Excellent tutorials no doubt. Thanks NINJA. I have a question. To let express know about my static files I used the 'public' folder [ app.use(express.static('/public'))] but this did not work until I changed to [app.use(express.static(__dirname + "/public"));] . Is there a difference? I thought it's the same thing!
@NetNinja
@NetNinja 3 года назад
Hey, the path is relative to your app.js file where you launch your node process. So if your public directory is in a different location to your app.js file, then you will need to build the absolute path using __dirname. Otherwise, you can just use use 'public' (no need to use '/' before it either). Hope this helps.

So far I can just pause the video and type it out, but there is value in typing ALL code with you and hear the discussion about it.
