This is a guest post from Dayana Jabif, Ionic Insider and co-founder of Ionic Themes and Angular Templates. where she helps build great UI templates for developers to get started with. Dayana writes often about what you can do with Ionic, Angular, and Firebase.
Images, audios, videos, text documents, pdfs, you name it. Files are part of our everyday life so learning how to handle them in our applications is a crucial task. In this tutorial, you will learn how to upload and download images to firebase storage from an Ionic app. We will explain how to handle both public and protected files. There were many use cases that came to my mind while writing this tutorial, for example: a learning app with public and private content where private content is only available upon subscription. Although this guide is about Firebase Storage, it’s important to mention that there are many other storage options available, such as Amazon s3.
Cloud Storage for Firebase is built for app developers who need to store and serve user-generated content, such as photos or videos. Files can be either public or protected using security rules to determine who has access to them. Firebase Storage can be used for any type of files, but in this tutorial we will focus on images.
We included examples of both cases: a section with public files visible to everyone and a private section, only accessible through authentication, where files are restricted. This means that just the logged user can access them.
Depending on your app needs, Firebase allows you to create your own security rules to allow read and write access to any file or group of files. We will see how to work with Firebase security rules for different use cases.
Capturing, uploading, listing, and deleting image files with Ionic is a typical task inside many applications. In this post, you will learn how to create an Ionic Angular app to handle both public and private images.
This app will work both inside the browser and as a native iOS and Android app. This is thanks to Ionic Capacitor because it provides APIs that work similarly across the different platforms!
