WaveSurfer is an open source audio player that renders the audio wave onto an html5 canvas.

The main page loaded by default is Index.vue under the pages folder, so we’ll add our code there for this example. The routes are saved in the pages folder. The main page is contained inside the element in MyLayout.vue, which contains a - the same vue-router you know and love. In order to use a Quasar UI component, you need to explicitly include them in, as we’ll see later. These are all Vue components written by the Quasar team (similar to the v- components of Vuetify). You can spot the Quasar components starting with q- e.g. The layout is a Vue component that has all the Quasar UI elements including a navigation drawer, a toolbar and a main page. Quasar CLI scaffolds a folder structure with the default layout MyLayout.vue inside the layouts folder. Now let’s have a look at the project structure the CLI has created for us, for a quick overview of Quasar.

If you’re building an app you want to work on android and iOS, I recommend periodically running it on both platforms. We’ll continue developing with quasar dev, while periodically testing on an actual device to see things are working. This is a crucial feature for an efficient dev process. Quasar will create a Cordova app that’s inner WebView loads from this IP, thereby giving us the ability to develop with hot reload on our device. Choose an IP that’s accessible from your mobile device (they have to be on the same network). Now the CLI asks you which IP to serve on.

Note2: If you’re building for iOS, it’s recommended to upgrade from the deprecated UIWebView (that Cordova uses by default) to WKWebView using one of the methods described here To solve this, uncomment https: true, under devServer section in

Note: Newer chrome versions block cleartext traffic by default, so Cordova’s internal WebView will throw an ERR_CLEARTEXT_NOT_PERMITTED error. Let’s start by installing the Quasar CLI. I assume you already have a working Cordova setup with android studio / xcode configured.

Use the Vue ecosystem you know and love.

Beautiful UI components and grid system built in (I like to write as little CSS as possible).

Vibrant and active community (11K GitHub stars).

More points that made me want to try it out: This is a crucial part of an efficient dev process, and one of the determining factors for me when choosing a framework /stack. You get debugging on actual device with hot reload out-of-the-box. It seems more mobile-oriented than Vuetify, and also has an excellent CLI that works great for generating Cordova apps. Quasar is a UI framework built on Vue.js.

We’ll load a local audio file from the device using html file input, render a waveform and add controls to play the audio. Once the user loads a file in the fileinput, the file should be loaded into waveformĭocument.getElementById('fileinput').We’ll use Quasar and WaveSurfer to build a SoundCloud like cross-platform mobile audio player app. When this happens, you will simply need to read the file as an array buffer and load it into WaveForm using the loadBlob method: Attach an event listener that will react when the user loads a file into the input. In order to provide the user a way to load a local audio file into waveform, you will need to initialize a simple instance of WaveForm and add a fileinput to your document.

In this article, we will explain you how to load a local audio file from the user's computer into WaveSurfer.js. However, it's usually unclear for a developer to know how to obtain a well formed blob from a local audio file loaded through a HTML5 File Input. Instead, the only way to do it is through a Blob that can be loaded through the wavesurfer.loadBlob method. Although its pretty simple to load an audio file into wavesurfer from a web URL, a lot of other applications that work with other resources will have problem loading the audio files through the default method.
