Sergio Cruz on the Challenges of Upgrading from AngularJS to Angular

Sergio talks about difficulties developers face when upgrading from angularjs to angular. He states that those who follow the recommended pathways in which to write angularjs (so that migration towards angular isn’t a hassle), will experience a migration process that is much more straightforward.

However, because angularjs isn’t very opinionated, there is no step-by-step tutorial for preparing developers for the upgrade. The fact that angular can have so many interpretations, makes this one of the biggest challenges for the framework shift to happen.

Another difference Angular has compared to the other frameworks is that both versions may run in the same app. Getting them to interact is also a tricky thing to do. With that said, Sergio explains that there are strategies to help make the transition less difficult. These include using typescript or modules such as Webpack, instead of manually downloading scripts or incorporating component-based architecture instead of obscure directives in the building process.

Sergio also describes the similarities between the move from angularjs to angular and the transition from global namespace to modules, that occurred in Ember. He goes on to describe a team of developers who chose to dedicate their time to solely focusing on the upgrade, and mentions the duration of this procedure.

Really like what he said at 8:35, following angular guidelines will really helps in the future as it follows best practices.
