09/15/2021, 1:28 PMwow I thought mine was slow haha

09/15/2021, 1:29 PMI’m using TypeORM and Inversify.
Adrián Mouly
09/15/2021, 1:29 PMThink that might slow things up.

09/15/2021, 1:37 PMWe have functions that cold start and complete their work in about 1.4s
Not sure how much of that is 'cold start'

Adrián Mouly
09/15/2021, 1:42 PMI might need to get rid of dependency injection 😂 .
Adrián Mouly
09/15/2021, 1:42 PMOr try other library.

thdxr
09/15/2021, 1:59 PMI'm at around 2s for the same cold start + finish work. I think maybe 2-300ms of that is the work + apig latency so probably around 1.7s
thdxr
09/15/2021, 1:59 PM~150ms of that is from fetching config from SSM

09/15/2021, 2:01 PM@thdxr you use middy for caching ssm?
t
thdxr
09/15/2021, 2:02 PMNo I do something freaky
a
Adrián Mouly
09/15/2021, 2:02 PMAh ok.
t
thdxr
09/15/2021, 2:02 PMI want loading ssm to block everything so that all of my modules can reference the values without any kind of dependency injection stuff. So I use deasync to block node until it's loaded

Adrián Mouly
09/15/2021, 2:03 PMNot sure what is deasync.
Adrián Mouly
09/15/2021, 2:03 PMFor those using RDS… any improvements on cold-start using Proxy?
t
thdxr
09/15/2021, 2:04 PMdeasync is a hacky library that can block node's event loop until a callback fires. It is evil but I need it for what I want to do
thdxr
09/15/2021, 2:05 PMSo if I have a module that's
Copy code
import { Config } from "./config"
console.log(Config.VALUE)a

09/15/2021, 2:05 PMI see, yes, Middy also has a middleware for eventloop blcoker.

thdxr
09/15/2021, 2:06 PMAh interesting. The reason I don't rely on middy for this is I seperate more core business logic from anything Lambda related. So this code can work even if just calling from a script outside of a lambda context
thdxr
09/15/2021, 2:06 PMSo it works in tests + random scripts I need
