Bank Migrates 450 Angular.js Widgets to Modern JS with Custom Compiler
An Italian digital retail bank built a custom compiler to transform 450 legacy Angular.js widgets into modern, fine-grained reactive JavaScript modules without rewriting templates. The compiler, inspired by Svelte and Solid.js, compiles templates at build-time to eliminate the runtime digest cycle. This approach avoids a costly 2-year rewrite and addresses security risks from unmaintained dependencies.

The custom compiler approach is clever but raises questions about long-term maintainability and whether it truly future-proofs the codebase against the next framework shift.
