Fetching mongoDB data with lambda functions

Hey @braveux and @lilbigwheel! Linking this conversation which I think may be useful:

Switching to FaunaDB on Netlify

Hi, While you can’t whitelist a serverless function’s IP, as long as your user password is secure, IMO it’s safe to use. In terms of faunaDB, they have their own documentation for using it on their site: Welcome to the Fauna documentation - Fauna Documentation Note that if your intention is to use faunaDB with referrer/IP whitelisting then won’t be using it via netlify functions, but isntead right through the JS client.

TL;DR There’s no way to whitelist an IP range for our functions because there’s no way to know which range they will be spun up on when they’re invoked. Our suggestions in the past have been to whitelist everyone but make sure you have a very strong MongoDB user password (and put your DB_URL in a Netlify environment variable)… or switch to FaunaDB.

Maybe not the answer you wanted to hear, but hopefully it’s helpful- let us know if you find workarounds or if we can answer any other questions on this!
