Top 10 Popular Javascript Frameworks and Libraries

With the rise of the Web 2.0 era of computing, JavaScript became increasingly popular for the development of user interfaces for applications, both web-based and desktop-based. With the expanded demands for JavaScript, an easier means for programmers to develop such dynamic interfaces was needed. Thus the concept of javascript libraries or frameworks developed. Lots of Javascript framework are available for you to choose. Here is the list of top 10 most popular Javascript frameworks.

  • jQuery

It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript.

  • Prototype
    Prototype takes the complexity out of client-side web programming. Built to solve real-world problems, it adds useful extensions to the browser scripting environment and provides elegant APIs around the clumsy interfaces of Ajax and the Document Object Model.

How to parse hashtag, mention and URL in a tweet

How to parse hashtag, mention and URL in a twit

I was trying to make a simple twitter application. Using jQuery and AJAX, grabbing twits was not that hard. But twitter returns twit in just simple characters. I needed to show the correct link for the mentions and hashtags and also needed to parse the URLs. So, after little search I came up with some Regex to grab it and then I made a simple function to parse twit. I needed such function in javascript as well as PHP. I just want to share that function here.


Simple regular expressions are used here. But you can use more robust and advanced regular expressions also.

For Mention

For Hashtag

Same output can also be obtained from PHP in server side.

PHP function preg_match_all matches the regular expression globally and it is similar to /g modifier. All the matches and to be replaced values are saved in the array. After parsing all, those findings are replaced at once by str_replace function.

URI.js – javascript library for working with URLs

URL is the address of World Wide Web page. A URL is a formatted text string used by Web browsers, email clients and other software to identify a network resource on the Internet. Network resources are files that can be plain Web pages, other text documents, graphics, or programs. URI and URL are sometimes used as synonyms but there is little difference between them. URL is technically a type of URI. For example: is a URL. URL consists of scheme (or protocol), authority, path and query string. There may also fragment in the URL which the string after # sign in the URL.

We may sometime need to manipulate the url in our site. We can manipulate the URL string from the Javascript side also. Using pure javascript to manipulate is not impossible but very tedious. URI.js is the Javascript library for working with URLs. It offers a “jQuery-style” API (Fluent Interface, Method Chaining) to read and write all regular components and a number of convenience methods like .directory() and .authority().

URI.js offers simple, yet powerful ways of working with query string, has a number of URI-normalization functions and converts relative/absolute paths. While URI.js provides a jQuery plugin. URI.js itself does not rely on jQuery. You don’t need jQuery to use URI.js.

How to use it?
First you need to include the javascript library in your page. You can download it from here. You can find URI.js file in the src folder. Now you are ready to use the awesome feature of this javascript library.
Lets take an example of manipulating URL string in ‘jQuery style’.

If you want to add ‘username’ in the URL string the use username() function and the library will place the name in the correct place and you dont need to worry a bit. Lots of API functions are available in the library like directory(), suffix(), hash(), fragment(), search(), tld(), hostname(), port(), domain(), subdomain(), etc. This plugin surely makes our life easy in manipulation of URL. relativeTo() and absoluteTo() functions are there to calculate the relative and absolute paths. Also you can easily normalize and clean the URL.

Want to compare two URLs. Dont worry! equals() function will check the URLs and return output as true or false. Moreover parsing URN will also be piece of cake using this library. In the latest version, it also offers jQuery integration. For the plugin to work, you need to regularly loadURI.js, as well as jquery.URI.js. URI.js does not depend on jQuery unless you want to use the URI.js jQuery Plugin.

We must appreciate the author of the library Rodney Rehm for the creation of such useful library.

You can find whole API documentation here [API Documentation]. If you want to understand more about the URL, visit this link [Understanding URIs].

There are some alternatives of URL manipulation library, if you dont like this URI.js.
