Just 14 mins into this video, I completely feel this is the best video for beginners out there who wish to learn node.js without much coding experience. Not all the highly viewed videos or highly liked videos are so understandable as this one.

Awesome course, In case you are having the error of "Error: Cannot find module 'ejs' " when you run node app from 2:25:24 run "npm install ejs" to fix this error

[@sleeksilk497]

Thank you, I just figured this out few minutes ago. Was wondering if ejs comes with Express or you'd have to install separately.

For example, I was able to do that for the form, but I know I was missing a lot because there were two after the and I don't know what else you had in your html.

Great tutorial. Here are some updates for joi input validation. Instead of joi.validate() use this format now. here schema is the schema object formed using joi.object() in this tutorial--> const {err} = schema.validate(req.body) if(err){ res.send(err) } else{ res.send('submitted successfully') }

(0:32:06) I think there is a better and concise way of writing it.

A simpler way to delete a non-empty directory. Add the optional second parameter (options object) and set the recursive key to true. This will prompt the rmdir function to delete the entire directory recursively. fs.rmdir('./newDirectory', { recursive: true }, (err) => { if (err) throw err; else console.log('directory and all files deleted successfully'); });

(whatever the random numbers). Then I put my eyes closer to the monitor of my laptop and noticed that I should use (`) instead of ('), the former is on the leftmost of the keyboard, while the latter is below the double-quotes.

I am just starting to learn node js after learning JavaScript. I appreciate the tutorial and how helpful it's been so far. Now, I am following the section "Working with the ReadLine Module" and on line 17 following the if() statement, I noticed there are no curly brackets. Is that how the code should be written?

Hey, nice video about the readline module. If you enter Ctrl + C in the command line it triggers the rl.on("close") event, and then go on saying you are correct.

So 2:00:17 - what is the benefit of preventing sending data via default submit post method, and rewriting it into ajax request?

On default, the site awaits for an Html file response and will display that if it gets one. Sometimes you don't want it to refresh or want to manipulate what is being sent with client-side javascript.
