Case Study

AngularJS to Angular Migration

A compatibility-first migration pattern for modernizing a legacy analytics platform without breaking existing customer dashboards and visualization configurations.

Problem

The platform needed to move from AngularJS to Angular while preserving a large library of existing visualization configurations already used by enterprise customers.

Approach

I used an interoperable JSON contract between old and new visualization layers, allowing the modernized Angular implementation to read existing dashboard definitions without forcing customer migrations.

Outcome

The migration enabled modernization of the frontend architecture while preserving backward compatibility for existing dashboards and reducing load times through API and rendering improvements.
