Code complexity is the enemy to productivity.

Tips to keep your typescript/node/react code simple:

• Minimize Dependencies
  • Eliminate as many dependencies as possible
• Minimize Imports
  • Especially watch for files imported from a great distance, the more complex the import path, the more likely it should be eliminated
• Minimize function input and output types
  • An inline type with only the required fields that are used in the function is the ideal input type definition since it only defines the minimal input interface
  • Never use type definitions that you don't control
  • Use implicit typing for return type when possible
  • Only declare the return type when you want to ensure type correctness of the function itself
• Minimize branching
  • Never use a nested if statement
  • Never use an else statement
  • Handle error cases first and throw an error or return early
  • Handle exceptional cases first and return early
  • Handle simple cases first and return early
  • As you handle the cases, the typescript type system will narrow the remaining type to it's remaining possibilities
• Remove everything possible - the bare minimal is always the goal
• Organize code by features not by structure
