Few tips to know for the first part ( Express) 1.) Watch-out for spelling of "Excercise", they have used "Exercise" 2.) While whitelisting IPs at Atlas, you'll have to whitelist all IPs if your ISP provides a dynamic IP i.e. those IP's which change often.

Very helpful tutorial for MERN stack. One issue I faced while doing it was that 'It wouldn't connect from my personal IP to MongoDB Atlas'. I was able to fix that issue by changing the network access setting in MongoDB to allow IP address from anywhere. If you are facing same problem fix it that way. PS: If you are having problem with him pasting code, you shouldn't be here. I believe this tutorial is for those who have the basic understanding of ReactJS, nodejs and express. Coding everyline would make it extremely long and hence uninteresting. You can learn the basics from other channels and come here.

[@abuahmed1186]

I took the complete lessons and i new nothing before starting this lecture on MERN. What a fantastic teacher sir you are. Lots of prayers for you. Regards

Really awesome tutorial. We've just gotten to the point in our bootcamp where we're tying together all the skills we've learned so far (i.e. the MERN stack), and this video explained how to connect everything in quickly and concisely. Thanks, Beau!

Hi Beau. I'm a totally beginner to MERN stack (coming from LAMP one) I have a MERN project to dive in and, fortunately, it seems that previous developers build it the way you described in your video. Then I feel so much more confident after only two hours seeing your video that I wanted to thank you sincerely! I didn't knew about this channel but now I'm hooked. Thanks!

If issue still persists , then please whitelist your IP on MongoDB atlas portal or just update the setting to "allow network access from anywhere"

Great Tutorial! Something I would like to say is that on 01:39:00 you said the difference between Class Components and Functional Components in React is that functional components don't support state and lifecycle methods which is not true anymore. You may use useState, useEffect and ... in functional components and they are even the preferred method these days. Thank you

[@Arkrez-vp2tt]

7/11/2022 Here are the issues and the fixes I ran into while following along, none of them were very severe and all but the last one was solved quickly. Error at 17:50 line 14 I was getting errors when I included the flags in mongoose.connect(), just pass the uri as the only argument. Error at 1:15:23 if nothing is appearing in the console, then that is probably because the page was refreshed when the form was submitted. All you need to do is go into the top right of the inspect panel, there should be two gears click on the lower gear for setting and select "preserve log", this will stop the console from refreshing. The final error I got is at 1:45:13 and says "params is not defined", for whatever reason you can't reference params like that anymore and idk how to get around it without making the component a function. The alternative solution is to grab the url in the search bar and snag the id that way. In edit-exercise.component.js go to componentDidMount() at the top paste "const arr = window.location.href.split('/');" This creates an array consisting of every step in the url path of our current page. Then in the axios.get() call replace this.props.match.params.id with "arr[arr.length-1]". This gets the last element of our array which happens to be the id of the exercise that we are editing. The ID is what we need to make correct calls to MongoDB. Do the same thing for the onSubmit function in the same file. (The final solution is not saleable, the more branching paths there are in the url, the harder it will be to maintain. If anyone knows a better solution, please let me know because honestly this one feels pretty hacky) Hope this helps someone!

Thanks for the free content. user is redirected to home page before exercise is actually updated in the database. this causes home page to display previous copy of the exercise. this is due to the fact that axios is asynchronous. so instead of using "windows.location("/")" after axios, better option is to use "history.push("/")" inside axios.then.
