Caleb I know it's 2 years later but thanks for this video bro. You've always had down to earth explanations that people from all learning styles can understand.

If you're watching this, here's whats going on with the 502 error:

Don't make a new variable in elastic beanstalk called "port"! Amazon already sets the environment variable for you...but they set the variable "PORT", not "port". So in your app.js code change "process.env.port" to "process.env.PORT" and things will work properly...

Except they won't. For a lot of you, you're still getting a 502 error. But that isn't because of the port; your application simply can't start, with or without AWS. The issue is that AWS is trying to run a command like "npm start" but it isnt working. On your local machine navigate to the project directory in your terminal and try "npm start". If that fails, then you've found the problem. Here's how you fix it...

npm start, by default, looks for a file called "server.js", not "app.js" like he told you to name your file. There are two solutions. The first is to change the settings in your project to make it look for "app.js" instead. The second solution is to simply change "app.js" file name to "server.js". I recommend the second option.

Repush after making these changes and you should be good to go.

Almost 3 years later, and this is the best tutorial i've ever seen. Thank you so much

[sebastianraab]

You, Sir, are a true hero. Not the hero we deserved, but the hero we needed.

[cliffvbajo]

I like that you showed even the errors you encountered so that it can help us debug/fix it. Thank you buddy! I will slap the "like" button and subscribe too!

[nishantsethi]

I am halfway to the video, the way you summed up everything. its marvellous and big thank you

For anyone watching and still getting a 502 error make sure to define a "start" script in your package.json, in my case I did:

"start":"node app.js"

Also make sure to define your port in env config and look in the logs to see which port your environment is running on

>"502 Bad Gateway, yeah!... so that's the end of the tutorial."
hahahaha

Yes caleb we are very interested on a tutorial on how to use mongo db with this. pls do

[josephwong]

Thanks a lot Caleb!
Love how you celebrate your failures/errors. That's the best attitude

[SrRunsis]

Man just what I needed! Thanks!

If any of you guys is having trouble trying to connect to a RDS Database from an Elastic Beanstalk Node.JS app check the SECURITY GROUP POLICY of the DB to accept traffic from Custom > Your Beanstalk Instance (this must be done manually) . Also check if you have a NPM RUN script in your package.json (it wont work otherwise) and your ENVIRONMENT VARIABLES set in the Beanstalk environment section.

instead of adding port as env variable you should use PORT(all caps) in your code for it to work also it is a good practice to have environment variables in all caps

[omerlev]

a good tutorial on how to deploy with aws. THANK YOU!!!!

[alexandermichaud]

This was exactly what I needed to get my app up and running. Thank you for a down-to-earth, straightforward tutorial

[nicholasdaniel-richards]

Bloomin eck Caleb - nicely done. I needed a very simple start for my first was deploy - I feel like I learned all the steps waaay beyond this and was missing this critical step. Subscribed. Thank you.

[noobminer]

I had a local env with mongoDB/atlas but it was impossible to find a tutorial on how to bring everything live. Your tutorial nailed it thanks!

[jameschhun]

Hey man thanks for this video, I used to watch you alot during my senior year of university for DBMS. Glad to see that 3 years later you're still producing content that is completely relevant to me haha

[adrianfittolani]

So good. Thank you. This worked great for me (had been trying to figure it out for a while). Site up and going, until it's time to hit the DB on Atlas! Would be great to see the Mongo DB part you were going to do.

[sohailb]

The best tutorial on deployment of node project on AWS! thanks

[visvm]

Cool Caleb. Tip for beginners, AWS EB considers app.js as default start script. If different, explicitly mention in package.json. "start": "src/app-main.js"
