# Basic Usage
Basic usage of Shaka Player is very easy:
1. Start with {@tutorial welcome} and compile the library.
2. Create a simple HTML page with a video element.
3. In your application's JavaScript:
1. Install polyfills.
2. Check for browser support.
3. Create a Player object to wrap the video element.
4. Listen for errors.
5. Load a manifest.
*NOTE: For simplicity, we will use `alert()` for errors in this tutorial.
In a real application, you would want a more appropriate mechanism to display
errors to your users.*
```html
```
```js
// myapp.js
var manifestUri = '//storage.googleapis.com/shaka-demo-assets/angel-one/dash.mpd';
function initApp() {
// Install built-in polyfills to patch browser incompatibilities.
shaka.polyfill.installAll();
// Check to see if the browser supports the basic APIs Shaka needs.
shaka.Player.support().then(function(support) {
if (support.supported) {
// Everything looks good!
initPlayer();
} else {
// This browser does not have the minimum set of APIs we need.
alert('Browser not supported!');
}
});
}
function initPlayer() {
// Create a Player instance.
var video = document.getElementById('video');
var player = new shaka.Player(video);
// Attach player to the window to make it easy to access in the JS console.
window.player = player;
// Listen for error events.
player.addEventListener('error', onErrorEvent);
// Try to load a manifest.
player.load(manifestUri).then(function() {
// The video has now been loaded!
}).catch(onError);
}
function onErrorEvent(event) {
// Extract the shaka.util.Error object from the event.
onError(event.detail);
}
function onError(error) {
// Log the error.
console.error(error);
alert('Error code ' + error.code);
}
document.addEventListener('DOMContentLoaded', initApp);
```
That's it!
