    Go mods seem a bit weird so far, always end up with Mongo drivers, must just be funky deps of deps but it's really unclear why they're added and `go mod why` doesn't say anything, and accidental imports start modifying your deps

    I made this mistake with (data is associated with a user), definitely separate the two, or have an implicit personal team for a user so you can transfer team ownership

    Pro tip for saas builders: Users and Accounts should be different things from day 1. Accounts own the stuff, and Users sign in to work in (one or more) Accounts. Splitting later can be hard for anything but the simplest of apps.

    Google's Cloud Functions are starting to sound more appealing than AWS Lambda — lots of built in libraries, in-cloud deps installed, env variables which actually make sense

    🍃 Parcel v1.9.0 does tree shaking on both ES6 and CommonJS modules! This is a HUGE deal since most of the code on npm is still CommonJS. Try it out today with the `--experimental-scope-hoisting` flag! 📝 Read more about how it works here:

    "if they are unnecessary and simply cute, don't do them" — - pretty sure I still do this always, and in Express/Koa/Mocha, it's always the multi-purpose functions or magical getter/setter that ends up never being worth the explanation

    worst case use a Lambda for access control logic. This kind of stuff will be the bulk of what most people work with in the future, almost completely client-side

    haven't tried any of this yet but it's cool to see AWS finally going after a Firebase style suite of client-side APIs , AFAIK with IAM pretty much every AWS service can be locked down and accessible to the client
