System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

AWS Lambda has nice safeguards for logging but not great handling for error reporting. I typically use Sentry but in this project, we're using Rollbar

Here's a setup to remove AWS Lambda's forceful exit on uncaught error and replace it with an error reporter to Rollbar:

// Load in our dependencies
const assert = require('assert');
const Rollbar = require('rollbar');

// Initialize our Rollbar handler
