scastie VS terraform-aws-lambda

From personal experience Scala also works. It's 100% possible to learn monads using https://scastie.scala-lang.org/ as a scratch pad.

Instead I typically use https://scastie.scala-lang.org, or an ammonite script, or just create a new file that extends App in my test directory. The thing that worksheets do better is that you can import things from your project (like the little app in the test dir) but they also show runtime values (like repl or scastie). However I've just never gotten them to actually work.

I strongly recommend you play around with the local Scala REPL. I have Scala 2.13 on my main dev computer and Scala 3 on my other computer. The local REPL will let you know when things are deprecated and give you hints as to what you should use instead. Scastie https://scastie.scala-lang.org/ can also be a big help.

Operationally, as you might expect from a language borne from academia, Scala tooling can be problematic and compilation can be slow--particularly if you are not yet using Scala 3, which only recently emerged and is very slowly percolating through the ecosystem (Remember the Python 2 to Python 3 transition?). But type inference, a vast standard library, and the time-tested reliability of the JVM make you very productive once you get the hang of them. Performance varies with the JVM you're running, but regardless you do have to contend with the size of compiled objects and the latency of garbage collection at runtime. When you want to experiment, you can skip the ceremony of writing a class or test and instead use a command-line REPL, an online REPL called Scastie you can share, or an outstanding third-party command-line REPL called Ammonite. Dependency management is achieved with SBT typically but also more general JVM build tools like Gradle and Maven.

I am using https://scastie.scala-lang.org/ which does compile server side in Scala. The UI is a bit hard to handle tho.

There are just too many required parameters to create a single handler. And then you need to do that N times for each handler. Take a look at a complete Terraform example for a lambda: https://github.com/terraform-aws-modules/terraform-aws-lambd...

For a personal project it's just a bit much in my experience, especially since most personal projects can easily be served by a t3.micro.

https://github.com/terraform-aws-modules/terraform-aws-lambda/ - this modules has it all. There are various examples and submodules in that repository to help you achieve all your serverless tasks the same way.

It’s also weird not to know about terraform modules. There are a lot of things you _can_ configure because there are a lot of things people need to configure but if you’re using something like https://github.com/terraform-aws-modules/terraform-aws-lambd... it’s only a couple of lines of config for a Lambda.

I use the Community Terraform Lambda Module to define the lambda. It allows me to define a lambda in just a few lines that are configured with a role and can also be easily extended with policies. The cool thing is that cdktf supports a type import. To do this, simply add the following module to the cdktf.json file:

As somebody already mentioned in the comments, you can use the terraform-aws-lambda module as well as many other modules for typical serverless services like API Gateway v2, AppSync, EventBridge, StepFunctions, AppConfig, DynamoDB, and many more.

You can containerize the lambda functions and when you deploy each lambda function, you can overwrite the CMD for each function in the resource block to match what you need. I'm doing something similar but only deploy 2 lambda functions which use the same source code but do very different tasks. I also strongly suggest you use the terraform-aws-lambda module since it will build out all related resources you need.

Have a look at this module: https://github.com/terraform-aws-modules/terraform-aws-lambda

I can't find any open issues on github or anyone asking for it other than in the modules that are provided. https://github.com/terraform-aws-modules/terraform-aws-lambda/issues/128
