We’ll use the Javascript signature_pad package for our functionality. Step 4- Save the created signatures in Android galleryīasic UI to test Signature pad functionality in Ionic 5 HTML code for is given in Step 3 Step 2 - Install required plugins Signature Pad npm package Step 3- Implement Signature pad functionality on web Step 1 - Creating a basic Ionic 5 Angular app If you are an experienced dev, you can just skip over the known stuff and jump to the section you need Structure of postĪs always, I’ll go step-by-step in the post. We’ll implement the Signature functionality in both PWA and apps. Besides having dedicated plugins for a lot of integrations, Cordova also has a huge community backing. Front-end: React | Build environment : CapacitorĬanvas can be implemented in any of the above, but for our example I’m choosing Angular Cordova framework.Front-end: Angular | Build environment : Capacitor.Front-end: Angular | Build environment : Cordova ✅.Canvas can even cater to PDF and other files, but we’ll stick to images for this post.ĭue to Ionic being platform agnostic, there are different types of Ionic Apps you can build for same functionality. You can draw/scribble on a designated area, resize it, change colors, put a picture in background and write on it etc. Essentially, we create a Canvas in the app, and let the user draw on the Canvas.Ĭanvas is a very powerful tool in HTML/Javascript.

Both of these are powerful but complex languages. If you create Native apps in iOS, you code in Obj-C or Swift. So, in other words - If you create Native apps in Android, you code in Java. Apps can be built with these Web technologies and then distributed through native app stores to be installed on devices by leveraging Cordova or Capacitor environment. It provides tools and services for developing hybrid mobile apps using Web technologies like CSS, HTML5, and Sass. Ionic is a hybrid mobile app development SDK. We will learn how to sign on the phone and then save the signature in phone’s gallery as a png. We’ll implement this functionality in an Ionic 5 Angular Cordova app. Getting hand signature on phone is a major addition to your app’s authenticity
