An app that makes the consultants activity reports filling cool, easy, and fast.
See our landing page at https://hellotrine.com if you provide your consultants to companies and at https://hellotrine.com/fr/customers if you have consultants working for your company.
I have open sourced this app because I've stopped its development, and replaced it by a React Native version (sorry MS).
This is a Xamarin.Forms project with a n-tiers architecture :
- model layer
- business logic layer
- data access layer
- presentation layer (here, a bootstrapper and 3 native mobile projects)
Each layer has its own abstraction layer in order to avoid dependencies. I'm using the Prism (with Autofac) IOC and DI engine.
The application is splitted in Prism Modules in order to enhance performances (lazy loading) and enforce loosely coupled components. There is one common module that is loaded at launch (authentication module), and three modules that are loaded depending on the user type (Consultant, Commercial or Customer).
Using the modular approach, I save loading time and memory by not loading UIs and Services the user won't use. Ex : the commercial or the customer will absolutely never create an activity report.
They are shared accross modules using netstandard 2.0 libraries.
Each services (BLL) and viewmodels are unit tested using xUnit. Every native mobile library I use are behind an abstraction layer, so they can all be mocked.
I'm using Xamarin.UITests library, that is using nUnit and Nespresso engine behind the scenes. The Page Object pattern is used in order to facilitate the UI tests. Since those are extremely slow to execute in the CI/CD, I only test critical user paths, only when releasing production binaries.
I'm using sentry.io for exception and crash logging, and Azure Application Insights for functional logs.
I've choosen Intercom service for customer support. So I'm using the Intercom SDK bindings for Xamarin.Forms in order to use directly the official native SDK for iOS and Android.
I'm using Instabug so my users and I can just shake the device in order to report a bug, with additional cool features like screenshots, annotations, attachments, logs, view structure reports etc...
