Let’s do big things. Together.

Recursion allows for solving a certain domain of problems with clarity, conciseness and elegance. Sadly, using recursion in TypeScript (Javascript) comes at a price.

In the first post of this two part series, we lay down the basic components for building a general string parser. We will use TypeScript and the fp-ts library, and basic knowledge of functional concepts (function composition, immutability) and data types (Option, Either) is expected.

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.
