Hi everyone, faast.js is a library that allows you to use serverless to run batch processing jobs. It makes it super easy to run regular functions as serverless functions. This is one of my first open source projects and I'd be happy to answer any questions here.

Hi,

Do you think serverless pricing model contradicts with batch operations ? I think that you normally pay for duration of tasks and ram usage etc. Batch jobs are supposed to be running long. I'm probably missing something here. Would you tell me little bit more ?

It depends on the specific use case. Some of the use cases I envision have sharp spikes in demand, and serverless can provide better service and price/performance. Part of faast.js is a cost analyzer that can tell you in real time how much your workload costs. What I found is that most people are probably using the wrong memory sizes for their lambda functions to optimize for price/performance. More on that when I write my next blog post... If you want a preview, check out this chart from the documentation: https://faastjs.org/docs/cost-estimates

This looks great! I have an upcoming processing-intesive project I hope to test this out on soon.

I especially like the cost estimate feature, that isn't something I've seen in such a seemingly simple tool like this before.

this looks super neat!

I've been wanting to make a graphql server framework that can run on lambdas, and will perhaps look into integrating with faast.
