2:47 - Wes tried Cloudflare Workers

Also this is so cool:

Hey Wes, just listened to the latest Syntax episode on the serverless setup. Not sure if it’s an episode idea or not, but if you wanna do a bit of a dive on Cloudflare’s service workers, I’m currently leading an “invisible infrastructure migration” right now from a legacy WordPress setup to a new Storyblok/Netlify setup. We’re using Cloudflare’s service workers to basically “stitch” the headers/menus/footers from the old WordPress site into our new Netlify pages, but serving the page back as if it was part of the normal domain. This means we can migrate from the old to the new slowly without massively disrupting SEO, doing a lengthy/costly rebuild, etc.

A word on Digital Ocean
Kubernetes + FAAS allows you to scale up/down

13:54 - Secret management

Some have a great UI
Some have a CLI
Some only have production
Some have dev/staging/prod

16:24 - Vendor lock-in

Two kinds of vendor lock-in
- Lock into a low-level provider (Like AWS, or MongoDB)
- Lock into a framework
Questions to ask:
- Can I go, take my app as-is, and host it on another provider?
- Can I refactor the config and run my code as-is?
- Do I need to refactor my code for it to run on other platforms?
Next.js will only run on Now
There is a community package
Begin all runs on Arc.codes
Firebase is locked in?

25:12 - Sharing dependencies

Each function will have its own package.json, which can be a pain
Publish utils a private module
AWS Layers
Import/export
Bundle and tree shake

30:26 - Local development

Now dev
NPX sandbox
Wrangler for Cloudflare workers

36:40 - Existing applications

Difficult to move with many routes, but easy to move a Graphql API that has one single route
Maybe do piece by piece instead of all at once
Begin has http express method

45:21 - Data

Any DB you want
Dynamo DB integrated into many
Firebase
KV Storage for Cloudflare workers
Fauna

48:14 - File storage

Generally files go in the associated file place like Amazon S3, Backblaze B2, Cloudinary
Many also have this integrated as well

52:18 - Auth

Serverless is ephemeral and stateless
JWT likely as sessions will work, but doesn’t really make sense
