laz-e v1.2.2

laz-e

asynchronously create DOM with a nice syntax.

usage

require:

// you must pass in window.document OR an object that implements the same API as document.
var e = require('laz-e')(document);

laz-e has the same syntax as crel except that it returns a function, that takes a callback.

also, any objects in the attributes will be JSON.stringified before being assigned as attributes.

var dom = e('div',
        e('h1', 'Page heading'),
        e('section', {'class': 'main'}

            'Welcome to my awesome webpage!',

            function(callback){ // An asynchronous 'child'
                setTimeout(function(){
                    e('span')(callback); // return a span after 100ms
                },100);
            }
        )
    );

// Pass a callback to the result to get the element.
dom(function(error, element){
    document.body.appendChild(element);
});

Because you pass in document, you can use laz-e in node, using a module such as dom-lite:

var domLite = require('dom-lite'),
    e = require('laz-e')(domLite.document);

var dom = e('div',
        e('h1', 'Page heading'),
        e('section', {'class': 'main'}
            'Welcome to my awesome webpage!',

            fs.readFile.bind(fs, './foo.txt'), // Load a text file asyncronously.

            fs.readFile.bind(fs, './bar.txt') // Load another text file asyncronously in parallel to the first one.
        )
    );

// Pass a callback to the result to get the element.
dom(function(error, element){
    response.end(element.outerHTML);
});
