Below are the javascript files that form cl-js library.


CL-core.js : forms the first part of the CL.js library. Core focuses on the low level plumbing of retrieving and pipelining data for processing.

CL-ui.js : provides functions for generating ui elements as well as a simple handlebars-like template substitution scheme for describing HTML elements. E.g. a template string of “<input value=”{{catname}}“> which is given an object like {”catname“:”fred“} would be rendered <input value=”fred">. The substituion happens at function envocation.

CL-feeds.js : provides the low level content retrieval functions needed to integration content from If you are reading the source to understand how to integrate content from in other languages (e.g. Go, Python, PHP, R or Julia) this is the place to look.

CL-feeds-ui.js : forms third part of CL.js. It is UI focused. It wraps DOM manipulations to provide support for configurable views of the data retrieved by CL-feeds.js. It’s main purpose is to support building other widgets as well as making the code generated by the widgets easy to understand when embedding in your own pages.

All together

CL.js : is a concatenation of CL-core.js, CL-ui.js, CL-feeds.js, and CL-feeds-ui.js into a single file for faster download.


Widgets are JavaScript libraries for generating HTML, CSS and JavaScript for integrating system specific Caltech Library content (e.g.

CL-BuilderWidget.js : is our first widget built to generate HTML and JavaScript to make it easier to embed or re-use our content in your webpage. It makes extensive use of CL.js. The generated code is for making the library content embeddable in your own webpage.
