SimpleQuery

Lightweight implementation of jQuery api subset. Designed as a thin wrapper around native browser apis. SimpleQuery is a small and fast library that you already know how to use.

Visit documentation site.

SimpleQuery core functionality will cost you less than 1KB. Import or require modules as you need them. Need to manipulate element classes? Require "classes" module and toggle classes with jQuery api you are probably already familiar with.

Keep in mind that SimpleQuery does not do all that jQuery does. By design this library is a thin wrapper of browser native apis. Because of that selecting elements will work only as good as native .querySelectorAll() does - as there is no custom selector engine implementation. What works with SimpleQuery will work with jQuery - other way may not always be true. At any time you can switch to jQuery and keep your application running.

This library is best used for applications which require small javascript footprint and have a strict performance budget. SimpleQuery is running on traffic heavy web application where jQuery is loaded as polyfill only when browser support is not good enough.

Examples

Import library for usage

var $ = require('simple-query');

Import modules needed for work you want to do:

// require classes, attributes and ajax functionality
require('simple-query/src/classes');
require('simple-query/src/attributes');
require('simple-query/src/ajax');

Profit:

// Manipulate classes
$('p.text').addClass('foo').toggleClass('bar');

// Manipulate Attributes
$('p.text').each(function() {
    console.log($(this).attr('title'));
});

// Get html from server and manipulate html
$.get('/test-html').done(function(html) {
    $('.content').html(html);
});

Full set of examples is available in tests codebase where you see what can and cannot be done with SimpleQuery api.
