In this video we'll learn how we can create a serverless database with DynamoDB.
Being able to create these autoscaling tables will enable you to create much more powerful applications. Whether it's storing user scores, product information or content, Dynamo is a great tool to be able to use.

Love your channel. Would love to see more videos on API Gateway. Keep up the good work :)
Thanks Jalal,
The next video is on creating an API which works with your DynamoDB table.
I could also add videos on adding other API Gateway features such mock responses, http proxy and security. They sound good?
You are a really great Teacher. keep it up sam!!
Thanks
You deserve more subs. Keep up the good work man.
Thanks Raghul. I will do!
nice explanation :) Thank you.
My pleasure :)
love your channel!
Thank you so much!!
really like that your videos follow each other! Thank you so much
Thanks Christopher
Hello Sam, Thanks for a great tutorial with well presnted content. I tried to check the serverless page and follow your tutorial, which was great but sometime some fo the code you presnting has changed. It would be useful if you provide an update to these voideos with any update serverless has presented. It might sounds a lot of work for you but you are presnting a great tutorial. Thanks again for this great tutorial...
Unfortunately AWS updates regularly and Serverless just released a new version. I'm working on some new Serverless V3 content
Hello Sam, still enjoying your easy to understand videos. Thank you once again. Just a quick question. In this video you show how to set up the primary key for your dynamo db table under resources in your yaml file. I note that the primary key is also the partion key. My question is; is there a way to set up sort key as well?
Yes there is. This leads onto a very interesting topic of table design. You can do some really cool stuff with sort keys that would work well for your multi game question in the other video. I'll be putting out a video soon but you can Google for dynamo table key design if you're interested
Why this guy is saying lying on the floor in the beginning? haha. Great lecture Thanks a bunch!
haha I've definitely upgraded by background a bit by now!
Hi there, love your videos and channel!!!!
Could u make a video about sis architecture and patterns ?
Or how to create an qa/prod environments in a project ?
tsk
I have one video on a sls architecture here th-cam.com/video/tOmmh-EFxQY/w-d-xo.html
I'll hopefully be doing more of these in the future.
I can definitely do some videos about environment management with Serverless projects. That's a great topic.
Please, videos about kinesis with lambda and appsync (graphql). Thanks
I've created a series using Amplify which uses appsync under the hood.
Would love to see tutorial on Lambda-DynamoDB database CRUD in Event Sourcing Architecture using AWS Kinesis
Have you looked into EventBridge? It's been designed specifically to work with event based architecture.
@@CompleteCoding no, I haven't. Will check it out. Thanks for the suggestion.
Can you explain how to add already existing subdomain to apiendpoint .I tried by using serverless as explained by serveless website but invain as it throws exception and then i add manually using aws console by adding custom domain option
Great question. If you have your domain in Route 53 then you can use BasePathMapping in your serverless file. This allows you to forward all requests to a certain domain or subsdomain to your API Gateway endpoint. This could be api.freeserverlesscourse.com points to your API. It's a bit complex to teach in a comment so I'll add it to the video list.
@@CompleteCoding Thanks a ton if you could teach us how to add existing subdomain but remember the subdomain is in one account and the parent domain (main domain) is in other account e.g I have production account where i have main domain in route53
and dev account where i want to create subdomain for devapi's
please make a serie like this but with python, I really need that :( thanks bro
The serverless.yml would be exactly the same with Python. With the lambda code it should be relatively simple to 'translate' the code. You'll just use Boto3 instead of 'aws-sdk'
So far I'm loving your content... What about a tutorial of how use instead of DynamoDB a Relational DB with AWS Aurora DB? Because I'm concerned about the cost of having a LOT of data using DynamoDB, that's my only concern.
I've chosen Dynamo as it is far cheaper until you get to a pretty large scale. Doing a video on Aurora is going to be more expensive to follow along and try yourself.
You would have to be storing a huge amount of data for dynamo to become prohibitively expensive. I have a table that has 28 million writes a month and it costs a total of about $16/month. If you are storing years worth of data then the storage costs could build up as the storage is $0.306/GB/month.
The cheapest Aurora DB is $0.048/hr = $34.56/month for a db.t3.small.
@@CompleteCoding Oh wow.. That's amazing! Then problem solved. Thanks again!
Why is the resources: label used twice? What can go directly under resources: other than Resources: ?
You can have "Outputs" in resources too. I'm not sure why they have to be nested in "resources", you'd have to ask someone from the serverless framework team
Hello sam, can you please share all the VScode extentions during practise we get an indentation errors..
If you press "CTRL + SHIFT + P" in VS Code that will open a command prompt. Type "indent" and select "indent using spaces" and the choose "2"
I copied code from github and get error:
can not read a block mapping entry; a multiline key may not be an implicit key in "D:\Projects\HDVE\HDVEServerless\serverless.yml" (46:20)
Does anyone know how to fix it?
Is your serverless yml file the same as this one? github.com/SamWSoftware/ServerlessTH-camSeries/blob/lesson5-dynamo/serverless.yml
with Yml files, the indentation really matters. It might be something like that?
Hi Sir, thank you for your videos they are so informative and to the point. I see that at 1:35 you used serverless-webpack, I would like to know how and why you used it? Secondly I tried to install serverless-webpack and got this error
The webpack plugin could not find the configuration file at: C:\Users\devgoel\myServerlessProject\webpack.config.js
I used this command to install webpack => npm install serverless-webpack --save-dev
At the time of creating the video, serverless webpack was the best way to bundle your code. This meant that instead of all of your src folder being uploaded to every lambda, webpack took just the files it needed. Packaging saves loads of upload data and also reduces cold starts.
Now I use serverless-esbuild. It comes by default whenever you use a serverless template now.
sls create --template aws-nodejs-typescript --path YOURPROJECTNAME
@@CompleteCoding thank you for your reply
@@CompleteCoding your videos are really knowledgeable and helpful
Hello sir , please make vidoe that how to insert csv data to dynamodb in serverless framework using lambad in nodejs
Do you mean an API that you send an CSV file to which puts it into Dynamo?
Or that you have a CSV on your computer that you want to add to Dynamo?
Please make a full blown web app using Amplify, AppSync, GraphQL (usage of Query - Mutations-Subscriptions etc), customize Resolver with some special features like sending SMS, Email and uploading files in S3. Also, It would be very helpful if you can make a front-end using Angular.
The Amplify and AppSync video is on the list.
@@CompleteCoding ok. Thanks
@@CompleteCoding Please provide the url
how did generate serverless.yaml file and why you didnt mention it?
This video is part of a series. I created the repo and the serverless.yml in a previous video
th-cam.com/video/sku9Rrci-tE/w-d-xo.html
hey could you please add episode number , so that its easy to find the next video . Thanks!!
This is part of a series with all the videos in order. Here's the link
th-cam.com/play/PLmexTtcbIn_gP8bpsUsHfv-58KsKPsGEo.html
It will be very good if code editor background color is white
I'll have to do a poll to find out which people prefer. Great idea
Why did you input 'serverless-webpack'?? You didn't explain it.
I have a video that I recorded almost 6 months ago and forgot to upload. Here it is:

@@CompleteCoding I'm sorry. Because I watch all your videos from oldest one so I didn't watch it yet. I will watch it later!
