In the following paragraphs I will be covering the power of a typescript monorepo and an alternative. This article is the first in a three-part series about monorepos. A basic JavaScript monorepo is fairly easy to get going but using TypeScript requires some additional configuration. An NX Workspace is a product from nrwl.io that extends the Angulars CLI (Command Line Interface) and creates an application project structure for a variety of frameworks and libraries, not just Angular. Enhance our tooling: Monorepos are often easier to navigate than having to understand and configure the relationship between dependencies. In the case that dependencies have to be changed across the project to accommodate a specific package, those changes can be made at once, together with the changes to the specific package. A monorepo as you are likely aware is a project structure that allows you to easily share packages of code within a project. The shell configuration has two main objectives. Pre-requisites: 1. 2. If you have a TypeScript codebase in a monorepo that is not using TypeScript project references then you are missing a trick. TypeScript would previously relate parameters that didn’t correspond to each other by relating them to the type any. It's a long and complicated process requiring human attention all the way.
