In the last post, we touched upon all the aspects of building a suitable context-free grammar for a recursive descent parser while building one ourselves for a language of simple arithmetic expressions. In this post we will use that grammar to build a parser library in Scala to validate simple…
This is going to be a series of blog posts where we will implement a recursive descent parser library in Scala using FastParse parser combinators for simple arithmetic expressions and cross compile the same in Javascript using Scala.js eventually utilizing it in a small Javascript application. Before we get…
In this blog post I will demonstrate how to connect React Navigators to Redux Stores. But first, let's quickly understand what react navigators are and why would we want to connect them to redux stores anyway. React Native doesn't have a built-in API for navigation like…
The react native library provides a component called SafeAreaView which facilitates containing the content within the safe area boundaries of a device thereby avoiding display notches or cutouts. It achieves so by applying padding to the nested content so as to avoid navigation bars, tab bars, toolbars, and other ancestor…
Persistent Entities in Lagom hold state of individual entities. In other words, they cannot be used to serve queries that span more than single entity. This requires us to create another view of the data that is tailored to serve rather optimized queries that span over multiple entities, which brings…
