How to add datepicker to jQueryBuilder in ReactJS
View react-jquerybuilder-datepicker.js
// important point is that the datepicker is not jQueryBuilder's plugin, but jquery-ui plugin being injected into jquery ($).
// order of imports matters -- the datepicker plugin is injected automatically into jquery and then automatically adopted by jQueryBuilder
import $ from 'jquery';
import datepicker from 'jquery-datepicker'; //
import jQueryBuilder from 'jQuery-QueryBuilder'; //
// this is how we initialize the query builder

bind not working for sinatra web server
View gist:ca5475afd4eace9a7287

I was trying to post this answer to stackoverflow but I was banned to do that. I believe the answer below may be helpful so I publish it at least this way:

I was running sinatra via MyServer, webrick_options

and after installing sinatra-contrib gem suddenly I was unable to to access my app from outside (localhost was working perfectly). All the hints with bind and -o were not working for me. What finally helped was to put inside webrick_options hash following key and value:

:Host => ''

You can’t perform that action at this time.
