AMPATH Update

Notes

AMPATH Team has been upgrading their Point of Care application from Angular 1.x to Angular 2.x, primarily for performance purposes. Most users are using tablets and an Angular 1.x application was facing performance problems. This was undertaken just as Angular 2.0 was officially released in October 2016.

The AMPATH POC application is now more modular. For example, the Angular Form Entry module is much easier for others to consume and it performs better.

Application is more modular compared to previos version written using angular 1.x.

Angular Formentry module Github repository: https://github.com/AMPATH/ng2-opemmrs-formentry

Demo

Users select a location

Default page is patient search

Selecting a patient takes user to dashboard

Vitals

Demographics

Contacts

Identifiers

Relationships

Workflows are designed around visits

Forms are geared toward tablets

Support swiping gestures

Native controls for dropdowns

Forms are 7-10x faster to load

Switching to Angular 2.x

Hard decision, but feel like it was a good decision

TypeScript has been a good thing (easier to debug)

Performance is far better

Most sites are using Angular 1.x version and team will incrementally switch sites to the Angular 2.x version of the application.

Challenges

Setting up the project is a bit of work, but after that it's easy

Now using orders API for tests. Plan to do the same for pharmacy orders.

They plan to share a demo of their application with the community in the near future.

Questions

Did you try react?

Considered it briefly, but AMPATH is familiar with Angular
