Seajs is a module loader for Web browsers. With Seajs, you can better organize your JavaScript code.

Core features of Seajs

Whether it is a small or medium-sized site, or large and complex applications, using Seajs can make our work easier and more enjoyable. Seajs has the following core features:

Simple and consistent module format.

Automatic management of dependencies.

Asynchronous parallel loading of scripts.

Rich plug-ins.

Friendly debugging.

The biggest benefit of Seajs is to improve the maintainability of the code. Each of the above features is described in detail in the usage documentation. If a website has more than 3 js files, it is appropriate to use Seajs to organize and maintain code. The more js files involved, the more appropriate the Seajs will be.

What Seajs pursues is a simpler, more natural way of writing and organizing code.

Getting started with Seajs

In the world of SeaJS, a file is a module. All modules follow the CMD specification, and we can write module code as we do in a Node environment:

Define (function (require,exports,module) {

Var$=require ('jquery')

Exports.sayHello=function () {

$('# hello'). Toggle ('slow')

}

})

Save the above code as hello.js, and then you can load it through SeaJS:

Seajs.config ({

Alias: {

'jquery':' http://modules.seajs.org/jquery/1.7.2/jquery.js'

}

})

Seajs.use (['. / hello','jquery'], function (hello,$) {

$('# beautiful-sea') .click (hello.sayHello)

})

That's all for "what seajs is". Thank you for your reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
