When working on any type of documents (whether it is code or not), we may want to compare different versions to see what has changed.

Some editors have this feature built-in where some don’t. Mergely is a free-to-use web app for making such a difference analysis quickly.

Documents can be uploaded with ease (or by mentioning URLs), the differences will be highlighted and it is also possible to merge them.

Mergely is also an open source JavaScript library (non-commercial) where you can integrate into your own projects.

Knowing the number of characters, words or paragraphs within a given element is sometimes necessary (when limiting them, informing the users, etc.).

Countable is a tiny and standalone JavaScript function that brings the ability to count all three.

It works very straightforward and has the option to count the inputs with stripping HTML tags.

Kartograph is a framework for creating interactive maps without any mapping provider (like Google Maps).

It consists of 2 libraries:

  • a Python library thatrenders vector maps from shapefiles or PostGIS and converts them to SVG
  • a JavaScript library for turning these SVG data into interactive maps

If you already have the SVG data (for ex: any drawing can be converted to SVG with Adobe Illustrator), only the JavaScript library can help too.

The JS library uses jQuery + Raphaël, outputs can be styled with CSS and a very good documentation is provided.

  • jsDraw2DX is a standalone JavaScript library for creating any type of interactive graphics with SVG (and VML for old IE browsers).

    Besides the ability to generate all basic shapes like line, rectangle, polygon, circle, ellipse, arc, etc., the library can draw curves, beziers (any degree), function plots, images and decorated text.

    The library is object-oriented and its coordinate system + scaling can all be configured.

    As it uses SVG, interactivity can be easily accomplished by manipulating the DOM.

    P.S. jsDraw2DX is built by the creators of jsDraw2D which draws any shapes using JavaScript.

  • Mobello is an open source JavaScript UI framework that simplifies developing mobile web apps.

    The framework aims to provide a native-like experience in mobile, it is optimized for touch events and has 20+ widely-used UI components.

    Mobello Mobile Framework

    It also has an IDE, named Mobello Studio, that focuses on building mobile apps with HTML5, CS3 and the Mobello framework..

    Mobello Studio has a drag 'n' drop enabled  visual design editor, a JavaScript debugger and built-in mobile device emulator.

    The API of the framework is documented in detail and it can be a good alternative to other popular ones if improved regularly.

    It is surprising to experience that JavaScript lacks of functions which are regularly required in most scenarios.

    Think of "looping a string", "if a variable includes given characters" or "capitalizing letters".

    Unless you use a JavaScript framework, these will require having custom functions (JS frameworks lack some of such functions as well which makes sense to keep libraries small).

    String.js

    String.js is a JavaScript library that brings such extra string functions with a tiny footprint (<2kb gzipped).

    It is standalone and has a jQuery-like syntax with chaining support.

    There are 25+ functions where each of them can find a use in any JavaScript-heavy projects. Simply, a must-bookmark.

    JSGL is a JavaScript graphics library for drawing and moving vector shapes with ease.

    The library enables us to create and transform objects (using SVG/VML) dynamically.

    There are built-in elements like line, circle, ellipse, polygon, etc. and support for stroking and/or filling them with many customization options.

    Demos provided (PathFinder and NeuralNet) give us a strong opinion on the capabilities of the library.

    In the beginning of the web 2.0 trend, tag clouds were one of the most popular items of web design. And, they were (and still are) very useful in helping readers to easily locate the most-used tags.

    Afterwards, the Flash-powered animated tag canvas came and it conquered many websites. The Flash -kinda- died, HTML5 is now everywhere and the animated tag cloud is still here for the new web built without Flash.

    TagCanvas

    TagCanvas is an HTML5 canvas powered and animated tag cloud that has both standalone and jQuery plugin versions.

    It has support for text +images and can be shaped as a sphere, hcylinder or vcylinder.

    The resource has so many settings for maximum customization and works even in IE (thanks to ExplorerCanvas).

    Zebra_Image is an open source and lightweight image manipulation library built with PHP.

    The library is object-oriented, requires only the PHP GD2 extension and supports resize, crop, rotate and flip operations.

    It works with .JPG, .GIF + .PNG formats and can convert one format to another after each action (transparency is preserved as well).

    Zebra_Image - PHP Image Manipulation Library

    For the most-used function, image resizing, there are various methods offered for a smart resize like "keeping the aspect ratio", "resizing with prioritizing width or height" and "resizing by cropping".

    It is also possible to define the quality of .JPG outputs.

    Ace is an open source, standalone and web-based code editor that focuses on providing a similar or better experience with desktop-based ones.

    It is actually developed for the well-known Cloud9 IDE and can be integrated into any web page easily.

    Ace Editor

    The editor's syntax highlighting works with JavaScript, HTML, CSS, JSON, PHP, Perl, Python, Ruby, etc..

    There is support for auto indent/outdent, completely customizable key bindings ad theming.

    Users can perform search/replace operations with regular expressions besides the standard method, toggle between soft tabs + real tabs and much more.
