Written by Cookielab staff. We talk about code, apps, data and things we do when we aren't eating cookies.
Even in simple, smaller applications we have to deal with configuration of some kind. Since we all know that hardcoding config values sucks, we tend to pick the easy-yet-flexible and powerful method - reading values from environmental variables.
At Cookielab, we use and contribute to many open source projects (OSS). Our primary motivation is not necessarily to give back to the community (which we care about greatly). The fact is that we use open source tools to help us to be more productive, and we usually use them for client-facing work.
Write tests, do proper code reviews, run your code before deployment, use database transactions, update dependencies, and on and on and on. Do these things - no matter your seniority - and be one of the good ones!
