Lightning
Base Components are great addition to the platform and in fact
revolutionary .One of the concerns around lightning component
development had been need to write too many lines of code and wire lot
of JavaScript code for simple things like handling check boxes ,select
list ,validations and so on .Having a base component library is
certainly great first step .
Lightning Base Components introduced in winter 17 release is documented here .Please note that many of these components are in BETA mode .
One
of the things as a Visualforce developer I found harder when I was new
to development was documentation did poor job to help imagine the UI and
how the components will render .I see the same issue with lightning
components developer guide .
While
the base components are listed and sample code is shown ,still to my
fellow designers I am sure this is night mare to imagine or even for
developers there will need to copy paste the code and preview how the
markup renders which is definitely not respecting their time .
I quickly made a small documentation that would help the designers as well .
Here is the link to the documentation on git
Here is a small unmanaged package in case you want to play around with all components
The package contains all components inside a simple lightning App Page
Note that there is lot of attributes that provides ability to do lot of Javascript actions declaratively and we will dig into each one of them via separate blogpost where I will test each of them and leave my experience and feedback .
