Wow, thank you so much. Really love your tutorials. Would be really nice to create an authoriser for our API gateway!
Thank you mate!

Would be nice to have a second part with authentication and authorization, also with some fron end fro users to request acces. Just an idea ! Thanks fro the great video

Thank you man, you saved me hours of study

Very useful, thanks. Had to run "npm install" before deploy after adding uuid and then yup dependencies, or it would fail on the server once API is called since after yarn alone apparently packages are not being deployed.

Can you explain why you use .promise() but don't set that promise to a variable to process fulfilled/rejected states? For example, in createProduct() you have:
await docClient
.put({
TableName: tableName,
Item: product,
})
.promise();

You add it at 15:30, but I don't really understand what the .promise() is doing

Thanks for the great video.

I got the error: The CloudFormation template is invalid: Template error: instance of Fn::GetAtt references undefined resource ProductsTable.

How can I fix it?

I can use that syntsx on the events within framework serverless? Mybresources on aws are deployed by terraform and just need yo creare the code for lambda function and tests
And my api is a api websockets

[spacetium]

each time I deploy using serverless deploy I get this error after some time loading
Serverless: Uploading service products-api.zip file to S3 (16.88 MB)...
Serverless: Recoverable error occurred (Your socket connection to the server was
not read from or written to within the timeout period. Idle connections will be closed.), sleeping for ~5 seconds. Try 1 of 4

I searched everywhere and no solution

Hey dude. This video was so useful. I have one question though.
Where's the DB located?
When I sign up to my IAM and go to DynaoDB I do not see ProductsTable.
Then where is it located?

Hi bro, I have a company as AWS solutions architect, I am still in training, I dont have knowledge of html/css/js/node.js rest-api dynamo.db, is it necessary for me to learn all these then create a application and test in AWS ?

[nwigweuzochukwu]

Can we see a similar video which follows a aTDD approach?

[tosinolugbenga]

I got an error Stack [product-api-dev] does not exist

[TCErnesto]

you're not using Express.js right?

[lordpablo]

Don't use aws-sdk, its outdated. Use the modular v3 SDK.

[browaruspierogus]

Amazon SDKs tend to get very ugly and abandoned in future
