Introduction to testing with Python

#python #testing #beginners

Checking that your program works is essential, in this post I'll show you how you can make sure that your app behaves as expected writing tests that will run in a blink instead of having to manually test the app trying every use case.

Unraveling callbacks with async functions

#javascript #tips #webdev #readability

Using async functions we can make our code easier to read and maintain, on this article I'll show you how I refactored real world code.

Custom useQuery hook for Apollo

#javascript #graphql #apollo #hooks

I need/want to query our GraphQL data using hooks but official Apollo support is not ready yet, so I wrote a custom hook to unblock our work until the official hooks are ready.

Sometimes we deal with deeply nested objects and we need to add extra checks to prevent our app from breaking while trying to access undefined parts of that object. Here's a not so usual way of doing so.

Redux and single purpose functions

#javascript #redux #webdev #testing

In this post I'll share a couple of lessons learned while working on SpiderOak Semaphor, where we use: Javascript and React to build our UI components, Jest to write our tests. and Redux to serve as single source of truth for our data.
