First of all, we note a possible misunderstanding: today we will talk
not about the engine, which is known to old-timers of Java programming called
JSDB and is still located at
JSDB.org . That engine based on Mozilla’s
SpiderMonkey , although it had rich capabilities for accessing databases, e-mail and the Internet, but after the appearance of a much more playful “competitor” (Node.js) gradually fell into complete oblivion, so to say I have nothing about him today.

Instead, I intend to suddenly draw your attention to the database of javascript libraries that appeared this current (2013) February at
JSDB.io and is open for replenishment by readers. (I’m writing "suddenly" because you and JSDB previously had some opportunity to pay attention: first,
mourner mentioned it
on Twitter on his Leaflet library, and then
alexzfort mentioned it
in the digest of new products last week.)
What makes JSDB happy? Reasonable interface and widespread use of AJAX to make changes to the page without reloading. (As a result, the interface is, for example, much more interactive and convenient than the thematically similar
jswiki wiki or the
JavaScript Territory site generated by this wiki.) At first, listing open source libraries on JSDB seems to be a simple list. However, since JSDB accepts open source libraries, which lies on Github, JSDB has a pleasant opportunity to respond to the mouse using the name of this or that Javascript library, automatically opening an information panel with a brief description of the library, counting its forks and stars and participants of its development on Gitkhab. (This panel expands in place of the clicked item, pushing the remaining items on the list.) The Readme tab will even more please the detailed reader, allowing you to completely download the selected library's
Readme file from GitHub without leaving for JSDB for this purpose.

What benefits does the JSDB website bring? But this: its contents serve as a horizon expander. How not to follow the development of modern open source, but still miss the emergence of a
two-three-other libraries (or mark them in the bud as hopeless, but they will eventually develop into something unusually convenient), so it is useful to meet them at JSDB and get to know with their productive capabilities.
It is clear that each of the readers will have their own list
of two or three libraries on JSDB with the interest found. About tastes and do not argue. For the information of readers, I considered, however, it is not superfluous to list half a dozen of my finds.
- Mousetrap is an interesting library for conveniently handling keyboard events. (Earlier on Habrahabr was reviewed by the koshak blogger , but then I somehow did not have time to test it.)
- Fuel UX : additional and / or advanced interface elements for Twitter Bootstrap. Of these, not all and not all will be useful - but who are useful, for those thanks to their authors. (Earlier on Habrahabr we saw a blogger INCWADRA , but either not everything, or since they have become more.)
- The same can be said about the jQuery ++ library: not all elements of its code (jQuery plugins) can be useful; but which are useful, they will bring a lot of benefit, saving the efforts of the web developer. (Earlier on Habrahabr were mentioned by blogger alexzfort in a digest for June 2012.)
- Toolbar.js is another jQuery plugin that can create pop-up panels with several “tools”.
- The jQuery prettyCheckable plugin serves as a spectacular and multi-colored stylist for checkboxes and radio buttons, and its elegant colors match the Twitter Bootstrap color scheme. (Previously, Habrahabr was not mentioned .)
And what do you find in JSDB?
