Migrations & Seeding

What are migrations??

Migrations are a way to make database changes or updates, like creating or dropping tables, as well as updating a table with new columns with constraints via generated scripts. We can build these scripts via the command line using knex command line tool.

To learn more about migrations, check out this article on the different types of database migrations!

  if (
    !req.headers.authorization ||

Visual instructions how to enable Google Maps on IOS using react-native-maps

UPDATE: Following instructions are now a year old. I have recently managed to upgrade react-native-maps from 0.17 to the latest version 0.21 with react-native 0.51 - if you want to follow my instruction scroll down to the end this doc! Hope that will work for you too!

This is for my personal use, things might not be correctly explained here. For the official docs please check https://github.com/airbnb/react-native-maps

Steps from scratch:

1.react-native init GoogleMapPlayground
