This comprehensive guide details the process of building a mood tracker app using TypeScript, Ionic, React, and MobX, and deploying it on Netlify to make it publicly accessible. The guide emphasizes the strengths of Ionic, particularly its React integration, which broadens its appeal beyond Angular. It provides step-by-step instructions on setting up the app's structure, creating pages for mood logging and history, and integrating MobX for state management to store data in the browser's localStorage. The tutorial highlights the use of Ionic components to enhance user experience, such as IonTabs for navigation and IonAlert for user input. Additionally, it discusses turning the web app into a mobile application using Capacitor and deploying it as a Progressive Web App on Netlify. The guide also suggests potential improvements, like adding persistent storage with SQLite or incorporating graphical charts for mood history visualization, encouraging further exploration of Ionic's capabilities.
