[Python] Build a CRUD Serverless API with AWS Lambda, API Gateway and a DynamoDB from Scratch

This is super helpful material. Your level of content and pace are great. Thanks a lot Felix!

Thank you! Lot of value here

plz share the code

share the code please it is not working for me get, patch methods. POST and DELETE is working

Thee best ever explanation I have saw about this subject.

Hello sir , please make vidoe that how to insert csv data to dynamodb in serverless framework using lambad in nodejs

Thank you for the tutorial. Can you provide lambda code with gitlab link?

can you please give the code?

It's work very well to me in POSTMAN and Requests in Python, but when I try make a request in my simple web page using Javascrip I'm having a issue call CORS "CORS policy: Request header field acess-control-allow-origin is not allowed by Access-Control-Allow-Headers in preflight response", someone know what is?

Great video. Thanks....pls I will appreciate if you can share this code. Something like the repo link

Hi Felix, I see 502 bad gateway when call GET /product API. What could I check to solve this error? Thanks.

This is a great video, super helpful! If I wanted to get all products with color "green", what would the scan body look like? Or would you not use scan for this functionality?

Im getting 502 bad gateway in postman with 'internal server error' message, how should I solve this

This tutorial is okay for AWS free tier?

whre i can get code of this project

Hey Felix, you are doing a great job and thank you for this wonderful tutorial. I coded along with you in this tutorial but after trying to invoke my function via postman, I got a 500, internal server error, however, that is not my most significant concern. How are you able to put all these pieces of code together, how are you able to know where and when to use a particular function, module or class? I understand the basics of python but putting them together to form one big program like what you just did is a nightmare for me. How are you able to write almost 250+ lines of code forming a single program without mistakes? Is there a manual you guys use when coding? what is that cheat code you use bro?

Thank you for this video it's very useful , can you do same one with Redshift Database

Could you please put your code on git and share a link.

Hi felix , your video in such a helpful can you share these code with me👍👍

Hi Felix, Can you please share the code because I'm getting error on my system as "Internal Server Error".
Please share code anyone.

Dislike, because you don't share the example code, what I supposed to do, copy it from the video?

Thanks for this Felix, could you please create a tutorial to explain the CRUD operations in dybamoDB via Lambda. Querying in dynamoDB seems to a whole subject in itself.

Where can we find the code?

Very nice start-point walkthrough video. Thanks Felix! Way to go!

Please upload the code also so that we can test it

"message": "Internal server error"
}

Is it better to have CRUD in one api or C R U D in 4 diferents lambdas?

Can you share your code?

Very very helpful tutorial for a beginner.. Thank you so much!

can i get the code??

can u plz start classes of python from beginer to advanced level??

Hi bro, excellent video, in the first time, was desperate jejeje, because I changed some variables and put the wrong variables necessary for all the code, also, I could add all tests for every method that you mentioned in the video, was very interesting, because if you don't know how to check the logs in. cloud watch, or you don't the correct syntax to write the dynamodb resources, you always get and internal server error 502. Thanks for this video you won a follower for your channel. Note: I broke my brain, trying to fix all my errors, but this is our world, we try to understand other codes and to practice every day until all are excellent. thanks again and regards.🤓

@Felix Yu, this video was really helpful thanks a lot!! I am stuck in integrating my lambda function, dynamodb and api gateway. Are you open to giving feedback on individual questions? Will be easier if I show you my approach and your coffee is on me for sure!

Can you make the video for SpringBoot? It would be great help

{
"message": "Internal server error"
}
how to resolve this

did any one got the code? can u share it with me

Hi, thank you for this. Could you send or post the text source-code please. Thank.

I've followed about 6 videos before trying to get this working and was unsuccessful.
A couple of things I took away from yours that made it successful for me:
- Your attention to detail and explanation of the code was very helpful.
- Setting the timeout to longer than 3 seconds I think is the golden thing that puzzled me, other videos didn't advise it, yet I think it helped!
- Case sensitivity is important. I named my key productid instead of productId and had to use cloud watch to figure out why mine didn't work.
- Not only does it work, I now have a code base as well as a base understanding to keep going. Massive thank you!

Awesome video... could you please create a video for RDS instead of Dynamodb

will anybody please let me know how much will it cost for this above project in the vedio @Felix YU

This was very straightforward and helpful. Thank you!
Experimented with stuff and followed along and learned much.
Just one thing, your python variable / object naming convention feels like Javascript (camelCase), while in Python the convention is variable_name.
So was confused for a short time xD.

Thanks!

could we have created a zip file that includes the custom encoder and uploaded that to Lambda? I think this should work. Your inputs would be very helpful

I have copied all of this code into VSC and got this working. No hassles there, barring a few glitches. I am thinking of creating a Git repository that could help out people who are on a learning curve wit Lambda & API (it's always a learning curve actually, but can be real steep in the beginning)

In a real life scenario, would it be a better idea to have different Lambda functions for delete, modify and add functions of a CRUD API? Just discussing the pros and cons vis-vis maintainability and testability
