Adding New Data to your DynamoDB Database

Complete Coding - Master AWS Serverless

Күн бұрын

In the last video we learnt how we can get data from an AWS DynamoDB table. in this video we're going to learn how we can add new data to that same table.
By the end of the video you'll know how to:
- add data to a dynamoDB table
- set up a POST endpoint in Serverless
- test POST endpoints using Postman
Code available at

This series of DynamoDB and Lambda API content is excellent and helpful to me. Consider creating a playlist for this in order of how the whole project was completed.

Really nice tutorial! I made some changes to get more realistic.. In post request, I removed the pathParameters and used the package uuid to generate a random ID when is a post request. With this I only use the body of the function instead of the body and the ID.

@CompleteCoding 3 жыл бұрын

Yes using UUIDs is a great idea.

Great tutorials thank you for that. How we can handle error when we write a ID which already exists in the table ? thank you again

@CompleteCoding 4 жыл бұрын

As far as I know there is no protection again writing a new file over an existing one. If you wanted to add this to the API, you would have to check if the file exists before trying to write. If you find a file then you can decide whether to return an error or overwrite anyway.

Great tutorial and series! I encountered something, in the the response parameters Content-Type header comes back looking something like this: "multipart/form-data; boundary=----WebKitFormBoundary2CeWzE6z88mA2xSh". The POST body pairs (Name, Score) are base64 has string, bookended by that "----WebKitFormBoundary2CeWzE6z88mA2xSh" string. Tried using Busboy but that got messy.

@johnbarker5686 3 жыл бұрын

Turns out in PostMan I was adding the body key/values as form-value, not Raw JSON. Oops.

Hello kind sir, I really like the tutorial and all, can you please just tell me also the name of the VS Code theme that you are using in the video? Thank you in advance!

@CompleteCoding 3 жыл бұрын

I use Monokai Pro. It's a paid theme but you get a few colour themes for $10. Definitely a worth while investment.

HI Sam, Thanks for sharing again. You have got the result in one shoot coding but How could I to manage any error? Could you say to me any idea because I have got and 502 Bad Gateway in Postman and I would like to fix it. I am seeing there are some console.log but where can I see them? Thanks.

@josejaimes4965 4 жыл бұрын

Jesus! This time was thought to find the error. It was only a bad sentence written. for me. I had written "const user = JASON.parse(event.body);" instead of "const user = JSON.parse(event.body);" BTW, your videos are incredibles. Thanks!

That's a brilliant little typo. Typos can be such a pain and I still do them all the time too

After getting the internal servor error I went to the api gateway to test it and in the logs they show me this error Lambda execution failed with status 200 due to customer function error: Cannot set property 'ID' of null. Lambda request id: aae9419b-6019-4d72-98b5-ad77643937cb. I'm stuck on it .

@CompleteCoding 2 жыл бұрын

Somewhere in your code you'll be doing something like body.ID = 'something' The error is saying that body is not an object, but is null. Check where you get the 'body' from in your code

@@CompleteCoding the line of let id = event.pathParameter.ID is the one that returns null I don't know how to deal with it I've tried the uuid but I don't know how to use it

@CompleteCoding 2 жыл бұрын

@@marwanehamdani2450I don't think that;s the line. That error would be "Cannot read property 'ID' of undefined" Your error specifically says "Cannot set property". What do you use that id for?

I did the same code and when I commented the line of user.ID = ID I got a succes but of course it couldn't find the ID I have to check another method instead of pathparameters I gues

Well for newbies it isnt a good video... you didnt explain the tools, how you setup the environment... just paste a code ..... and "automagically" everything is working.... probably is a good video for people that already knows the 1st part... anyway thanks for share it...

@CompleteCoding 3 жыл бұрын

Thanks for the feedback Marcelo. This video is part of a longer series on Serverless where I go from setting up Serverless and AWS, create the repo and build everything that you see at the start of the video. I can see how jumping in at this video might not make loads of sense. I'll try and make it clearer in the future that this is part of a series.

Hi Sam, I'm really enjoying this video series on Serverless - thanks so much for putting it together. I particularly appreciate the slow pace and bitesized nature of each video. Great work :)

@CompleteCoding 2 жыл бұрын

Thanks Eddie. I also enjoy learning from bitesized videos. I can easily rewatch bits I need to or skip videos I already know
