The @angular/compiler package is a crucial component of the Angular framework, responsible for transforming Angular templates and code into executable JavaScript instructions. Analyzing versions 14.0.0 and 13.4.0 reveals key distinctions that impact Angular developers.
Version 14.0.0, released in June 2022, declares a peer dependency on @angular/core version 14.0.0, indicating it's built and optimized for use within the Angular 14 ecosystem. Its unpacked size is around 8.9MB with 116 files. Version 13.4.0 targets the Angular 13 framework and had its release date in April 2023. It comes with more files than v14 (around 219), although the unpacked size is smaller, around 8.8MB.
For developers, the most significant difference lies in the targeted Angular core version. Choosing the appropriate compiler version is essential for compatibility. If you're working on an Angular 14 project, using @angular/compiler@14.0.0 is mandatory to leverage the framework's features and avoid potential conflicts. Conversely, if your project is based on Angular 13, stick to version 13.4.0 of the compiler.
Beyond basic functionality, each version includes feature enhancements and bug fixes, to improve template compilation. These improvements typically increase performance and provide improved error handling. For instance, the compilation process might be faster, and error messages could be more descriptive, to improve the overall developer experience. Specific details can be found in the Angular change logs for each major release. These kinds of updates influence the structure of the generated JavaScript bundle in a way that can contribute to a better rendering speed or smaller final file sizes.
