Building Lambda functions with Node.js - AWS Lambda
Run Node.js code in Lambda. Your code runs in an environment that includes the AWS SDK for JavaScript and credentials from an IAM role that you manage.

August 16, 2018 - Awesome! Now you just need to add a name and role for the function and finally start writing some code. Regarding the role, feel free to just pick an existing role such as lambda_basic_execution. It will more than suffice for this simple example. Make sure not to forget adding Node.js 8.10 as the runtime either.
As a backend web dev, working with Lambda (node.js), RDS, Dynamo, and S3 - what is your workflow?
I'd recommend looking into CDK for a way of writing infrastructure as code. This is built by Amazon and is essentially a 1 to 1 mapping to Cloud formation templates. For a more abstracted approach, check out SST but this is still in its early days, especially V3. For production you should never be managing infrastructure directly through the console, and should instead use an infrastructure as code tool with a cli to update your deployed infrastructure automatically.

i kinda doubt, because it would involve at least three different subjects: lambda basics (lambda config, lambda environment, iam, cloudwatch) the programming language of your choice (e.g. python) aws client connectivity for that language (e.g. boto3) More on reddit.com

November 23, 2022Why would I use Node.js in Lambda? Node main feature is handling concurrent many requests. If each request to lambda will spawn a new Node instance, whats the point?
That’s not really unique to Node. The majority of languages and web app platforms have concurrency mechanisms that will process multiple requests simultaneously. That is certainly a drawback of Lambda if you’re looking at raw CPU cycle efficiency and your application spends a lot of time waiting on synchronous downstream calls, but in most cases that doesn’t really matter. In practice, there are a lot of apps that can either use really fast data stores like Dynamo or use asynchronous processing models that minimize the amount of idle CPU time for a given request. Also, even with some inefficiencies when looking at high concurrency time periods, sometimes the ability for Lambda to immediately scale down during troughs in your load pattern makes up for it when looking at the global efficiency of the system (especially when you consider other operational overhead like patching servers.) Bottom line, people use Node with Lambda because they like the language and are familiar with it. Using the same language for the front end browser code and the backend is nice for teams that build full stack web apps. More on reddit.com

February 8, 2020How to deploy Node.js Lambda?
To deploy a Node.js Lambda function, write your code, zip the project directory (including node_modules), then upload it via the AWS Lambda console, CLI, or through AWS SAM/Serverless Framework. Set up the required handler and permissions.

How to build Lambda layer for Node.js?
To build a Lambda layer for Node.js, package your Node.js dependencies into a nodejs directory, zip the directory, and upload it to AWS Lambda Layers via the AWS console or CLI. You can then attach the layer to your Lambda function to reuse dependencies across functions.

NodeJS Lambda | The Complete Guide to Get Started 101
Why use the Lambda function?
Lambda functions are useful because they allow you to run code without provisioning or managing servers, automatically scaling to handle varying loads, and only charging for the compute time used, making them cost-effective for event-driven applications.
