![]() Unfortunately this API is not supported by Safari or Firefox.Chrome on Android, will display a simple dot, not a number.Desktop - Chrome and Edge browser will display the number returned by the tAppBadge().Here is the demo you can try on! Alternatively, there is also an NPM package available that you could use in your PWA application. Both tAppBadge()and navigator.clearAppBadge() are asynchronous methods and return a promise.Ĭonst unreadBadgeMessages = 42 // Setting the badge // // see if the browser supports the badging API if (tAppBadge).Published on Monday, Ap Updated on Wednesday, June 1, 2022. To clear the badge you can use navigator.clearAppBadge() or use tAppBadge(0). The Project Fugu API Showcase is a collection of apps that make use of APIs that were conceived in the context of Project Fugu.Then you need to set badge using tAppBadge().As usual, you need to check if this is supported by the browser.One thing to note here is, you will never set the value to 0 if you accidentally set it to zero, the state will be set to nothing automatically. An unassigned long value/ unsigned integer: This is the value you would set.Flag : When you set the flag but there is no update on the app value to show it on the UI.Nothing: There is nothing set to the badges Or the user has already addressed them.It cannot read back the value set earlier. Also, understand that this API is write only. Three Badge States:īefore we set the badge programmatically, you need to understand that there are three values a badge can take. The badges will show only if you have already installed a PWA application on your OS/ device. The badge types which gives unread count or event type on This API provides users a visual indication that there is some info available to the user or something needs to be done by the user (like the exclamation mark on the example below where the user has added something to the cart but has not placed the order yet). ![]() When he wears them, face recognition wasn’t very smooth, my Pickle Rick move with visible steps.Badging API Example Why do we need this API? Indeed Gérôme as you can see wear big glasses. If you wear glasses but big glasses, the recognition could be very lacky. ![]() Here is for example how you can detect a face: const faceDetector = new FaceDetector( // The landmarks aren’t well positioned (it’s a bug too bc914348)įun fact, the face recognition is based on eyes position, it is a COVID proof API □□. Indeed, a canvas can generate data that the detector could interpret. An image is nice, but a canvas is better □. This API is interesting because with very few lines of codes you have something that gives you the position of shapes detected in an ImageBitmapSource. The shape is restricted by the web platform, you could recognize a face, a barcode or some text (not implemented yet) Under the hood TLDR This API lets you find your shapes in images. The main idea of this hackathon was to play with the Shape Detection API. Push the limitĪs you can imagine, we wanted to create a fun Hackathon, a hackthon where the fun and the creativity were more important than the social impact of the result □. ![]() If you are curious about what we done, you can read this article □. The shape detection api is very easy web API to use but it has lots of limitations according to the platform you have. A month ago, I organized (with a colleague of mine, Gérôme Grignon) a Hackathon based on the Project Fugu “Shape Detection API”. ![]()
