Build Optimization Build Optimization Build Optimization Build Optimization Build Optimization Build speed directly affects developer productivity. Slow builds break flow, reduce iteration speed, and discourage best practices like running tests before committing. This article examines build optimization strategies across different languages and tools. Build Caching Build caching stores the output of build steps that have not changed. When a source file changes, the build system only recompiles the affected parts, reusing cached results for everything else. Effective caching is the highest-impact optimization. Incremental compilation is the most basic form of caching. Compilers track which source files have changed and only recompile those files and their dependents. TypeScript, Rust, Go, and modern Java compilers all support incremental compilation.…
