Build an excellent video player application using Webman
With the rapid development of the Internet and mobile devices, video playback has become an increasingly important part of people's daily lives. . Building a powerful, stable and efficient video player application is the pursuit of many developers. This article will introduce how to use Webman to build an excellent video player application, and attach corresponding code examples to help readers get started quickly.
Webman is a lightweight Web framework based on JavaScript and HTML5 technology. It is easy to use, efficient and stable, and is very suitable for building video player applications.
First, we need to prepare the required development environment. After installing Node.js and NPM, we can use the following command to install Webman:
npm install -g webman
Next, we can create a new Webman project and execute the following command:
mkdir video-player
cd video-player
webman init
The above command will create a Webman project named video-player in the current directory and initialize it.
Next, we need to add the required dependent libraries. Execute the following command in the video-player directory:
webman install axios
webman install video.js
The above command will install the axios library and video.js library. axios is a library for sending HTTP requests, and video.js is an open source HTML5 video player.
Create an index.html file in the video-player directory and add the following code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>视频播放器</title>
<link rel="stylesheet" href="https://unpkg.com/video.js/dist/video-js.min.css">
<style>
.container {
width: 800px;
height: 600px;
margin: 0 auto;
}
</style>
</head>
<body>
<div class="container">
<video id="my-video" class="video-js vjs-default-skin" controls preload="auto" width="800" height="600">
<source src="path/to/video.mp4" type="video/mp4">
</video>
</div>
<script src="https://unpkg.com/video.js/dist/video.min.js"></script>
<script>
var player = videojs('my-video');
</script>
</body>
</html>The video tag in the above code defines a video player and is specified through the source tag The path to the video file to play.
Next, we need to add a routing configuration in Webman's configuration file webman.config.js to return the index.html file:
// webman.config.js
module.exports = {
routes: [
{
path: '/',
method: 'GET',
handler: (req, res) => {
res.sendFile('index.html', { root: __dirname });
}
}
]
};Execute the following in the video-player directory Command to start the Webman server:
webman serve
Visit http://localhost:8080 in the browser to see the video player application we built.
The above are the steps to build an excellent video player application using Webman. Through this simple example, we can see that the development experience of Webman is very good. Combined with the powerful video.js library, we can easily build a powerful video player application. I hope this article will be helpful to readers, and everyone is welcome to try to use Webman to build more exciting applications in actual development!
