The Locality principle in Angular Ivy refers to a design approach where each component in an Angular application is compiled using only the information about the component itself and its direct declarable dependencies, such as its templates and styles. This principle is a key aspect of the Ivy compilation process, emphasizing that no additional metadata from dependencies is required to compile a component[1][5][7].
This approach simplifies the development process by ensuring that changes in one component do not necessitate recompiling other components unless they are directly dependent. This not only speeds up the development cycle, particularly during incremental builds and hot-reloading, but also enhances the overall performance and optimizes the build process[1][6].
Furthermore, the Locality principle supports more efficient tree shaking and smaller bundle sizes because Angular kno...
