Steps for setting up lambci on procore production

https://github.com/lambci/lambci#installation
create a minimum apex role permission and attach it to the lambci execution function. that way, it can deploy apex.

Minimal AWS permission required for for APEX and LambCI for setting up Procore-Lambda

Why?

Some of our tasks require C bindings, such as imagemin, phantomjs, etc. These C bindings need to match AWS Lambda's linux. We need to build native modules in an environment that is the same as AWS Lambda so all the C++ bindings will work using AWS Lambda.

Alternatives

spin up aws ec2, build the assets there, download them, and deploy from local machine.
use circle-ci, and https://github.com/lambci/docker-lambda to build the binaries and deploy apex from inside the image
use https://github.com/lambci/docker-lambda to build the binaries and deploy from local machine.

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called Reactive Programming, particularly its variant comprising of Rx, Bacon.js, RAC, and others.

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.

	This policy provides a single, authoritative, and machine-readable source of truth for AI coding agents and humans, ensuring that all work is governed by clear, unambiguous rules and workflows. It aims to eliminate ambiguity, reduce supervision needs, and facilitate automation while maintaining accountability and compliance with best practices.
