Knockout 3.1 ships

Knockout is so, so good.<p>I just wish it had proper API documentation. There are no real docs, only examples&#x2F;tutorials, this can be quite frustrating.<p>If you&#x27;ve never used data bindings in HTML&#x2F;JS, you HAVE to give this a try.<p>If you&#x27;re still using jQuery &amp; other manual event handlers to change the state of your UI, you GOTTA try it!

Release notes: <a href="https://github.com/knockout/knockout/releases/tag/v3.1.0" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;knockout&#x2F;knockout&#x2F;releases&#x2F;tag&#x2F;v3.1.0</a>

I absolutely adore Knockout.js.<p>I&#x27;m building a large enterprise SaaS system single handedly and while I&#x27;m a competent to good backend developer my front end skills are weak (mostly ancient JS and then jQuery stuff up to writing jQuery plugins) and Knockout has saved my bacon (when combined with Bootstrap 3).<p>It took me a weekend to get my head around the approach (and force feed some JS knowledge I was weak on) into my head and then on the Monday I wrote my first custom binding handler to allow me to do async file uploads (think Gmail attachments) as easily as<p><pre><code> &lt;input data-bind=&quot;ajaxfile: { property: &#x27;photo&#x27;, url: &#x27;&#x2F;ajax&#x2F;upload&#x27;, maxsize: 8388608, image: true}&quot; type=&quot;file&quot;&gt; </code></pre> The ability to use that to upload a file into the temporary store, return the hash for the file which is then submitted when the form is saved makes for a nicer UX (I hate those You clicked save not wait 5 minutes while we attach these pdf style messages) and has saved me a huge amount of time trying to shoehorn more complex jquery plugins that kinda-sorta do what I want if I squint at them.<p>The actual architecture is multi-page with each page been bound to it&#x27;s own view model (as the vast majority of pages are either forms, editing forms or showing tables) this has worked out really well so far (I also have a custom binding to bind a knockout property directly to a jquery datatable 1.10 instance which has made life somewhat easier but it&#x27;s hairy code (on the limit of what I&#x27;m capable of with javascript)).

Knockout is my go to library when I need data binding. It&#x27;s lightweight and doesn&#x27;t interfere with your markup.

It always baffle me how little people here talk about DurandalJS (that uses knockout for its bindings). It is a nice alternative to angular... and it uses knockout which is awesome. If you like knockout, you should really take a look at it.

I love knockout but I&#x27;m not sure whether to risk using it in mobile apps. Can anybody report on performance in a mobile SPA with a few views?

Any Django developers interested in Knockout may want to checkout my Django-Knockout-Modeler project:<p><a href="https://github.com/Miserlou/django-knockout-modeler" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Miserlou&#x2F;django-knockout-modeler</a>

This is awesome, always happy to see continued work on Knockout.<p>We use it in our production single-page app at sendwithus, and while AngularJS is tempting, Knockout is so lightweight and nimble that it lets us move really quickly on front-end features.

I&#x27;m a big fan of knockout. I find myself using it in a lot of places. The declarative binding makes it so much easier to come back months or weeks after writing code and clearly see what is going on. That is opposed to the old way of using Jquery and a mess of glue code to tie models and elements together. Knockout has also saved me a lot of time and reduced the amount of javascript needed significantly.

knockout is such an awesome library. I have only used it for a few toy projects, but I love how lightweight it feels; and how it doesnt feel like it takes over all of your html.<p>I also love how the ko.observable doesnt feel as magical as the angular binding. It makes me feel alot more in control

Using knockout since shortly because it&#x27;s more supported on .Net (it will ship with Visual Studio).<p>And i have to say, i&#x27;m amazed by it.. It&#x27;s pretty awesome to create my first EditableHTML :)

What about Ractivejs.org? It looks similar. Can anyone compare their experience with the two?
