Has anyone here got much experience using Clojure/Clojurescript on AWS Lambda?

@peterwestmacott I’m fairly sure uswitch had support framework for doing lambda functions in AWS.

yeah they do

lambada

Oh thanks, I'll take a look.

I was imagining using clojurescript, but that looks super straightforward, so I'll start there. Thanks again!

@peterwestmacott what are you trying to do with it? I've done a fair bit and run a couple of workshops

Probably some https endpoints to write small bits of json to s3.

imo there's two good ways to do it

cljs-lambda library is good

or you can go directly to node via cljs and either shadow-cljs or something like node figwheel

iirc for the workshop it was node-figwheel?

here's the workshop notes https://gist.github.com/the-frey/767a9c403e691df9915e3ecf04f05594

basically cold starts make the JVM way way slower than node so cljs is 100% the way to go

& honestly I need to re-write this workshop to use shadow and lean more heavily on going direct to the node-aws-sdk

but yeah, the serverless framework (confusingly named, it's a node framework that gives you offline testing etc) makes lambdas on aws p easy in node and cljs can speak to it pretty easily

& here's the end state of the workshop I think.. not the nicest code I've ever done but shows how it fits together I think https://github.com/envoylabs/cljs-serverless-workshop/blob/add_csv_and_cljs_lambda/src/cljs_serverless_workshop/core.cljs

Wow, thanks!
