TypeScript Monorepos: Run Tasks and Tests Based on Git Refs

As TypeScript monorepos grow, running tests and builds for the entire codebase quickly becomes slow and inefficient. You need a way to target only the code that actually changed. This text-only course guides you through the core concepts of monorepo dependency graphs and Git-ref-based task execution. You will learn how to analyze changes, configure modern workspace tools, and optimize your development workflow so you only run tasks on affected projects. Through clear, written explanations and practical code snippets, you will master: - Understand the foundational concepts of monorepos, dependency graphs, and workspace configurations. - Analyze Git refs and commit history to identify changed files and affected projects. - Configure task runners to execute tests, builds, and lints only on modified code. - Implement modern workspace tools and caching strategies to eliminate redundant work. - Structure type-safe TypeScript project references for robust boundaries and faster compilation. - Integrate affected task workflows into continuous integration pipelines for rapid feedback. Starting with fundamental monorepo architecture and dependency mapping, you will progress through written explanations and step-by-step configuration guides to implement precise task filtering. This course is designed for developers looking to scale their TypeScript projects, with no prior monorepo optimization experience required.
