Angular developers considering an upgrade to @angular/compiler version 19.1.4 from 19.1.3 should primarily note the updated peer dependency on @angular/core, mandating version 19.1.4. This ensures compatibility and seamless integration between the compiler and the core Angular framework. While the direct dependencies on tslib remain consistent, the upgrade focuses on aligning internal components for optimal performance and stability within the Angular ecosystem. Both versions serve the crucial role of compiling Angular templates and components into efficient JavaScript code executable by browsers, enabling the dynamic functionality of Angular applications. They share a common foundation, including MIT licensing, access to the official Angular repository, and the same author. The file count and unpacked size in the distributed package stayed identical between the two versions as well.
The key distinction lies in the peer dependency requirement, compelling developers to upgrade @angular/core simultaneously when moving to @angular/compiler 19.1.4. While the releaseDate differs; 2025-01-29T23:08:53.297Z compared to 2025-01-22T19:41:45.291Z, this is more relevant for managing updates. By upgrading you will benefit from bug fixes and improvements incorporated into version 19.1.4 since the earlier release. This upgrade helps keep your Angular projects aligned with the latest enhancements and bug fixes.
