Mongo styleguide

MongoDB Style Guide

General

  • Don't mix types. Do be conservative in what you write liberal in what you accept
  • Don't use the empty string or 0 for their falsiness. Do make non-casting, explicit comparisons

Enums

  • Don't use numbers, booleans or any other types to model enumerations. Do model them as uppercase string constants, e.g. "WAITING", "IN_PROGRESS" and "COMPLETED".

React Native vs Native

React Native

+++ Our team has lots of experience with JavaScript + React

+++ Build once for both platforms

++ Much better developer experience (faster turnaround times)

+ Can update without having to go through the app store most of the time
