The article explores how TypeScript Project References can enhance performance and efficiency in managing monorepos by allowing TypeScript to treat a workspace as a collection of interconnected projects rather than a single unit. It explains the process of setting up project references by adjusting the `tsconfig.json` files, using path aliases, and enabling the composite compiler option. This setup allows for more efficient builds by identifying out-of-date projects and compiling them in the correct order, significantly reducing memory usage and CI costs. The article also highlights the advantages of using Nx to automate the management of project references in large monorepos, although it notes that Angular does not yet support TypeScript Project References. Future articles in the series will delve deeper into managing TypeScript packages in monorepos.
