FYI: kdb+ web components

Hi,

I’ve recently added a javascript library to https://github.com/quintanar401/kdb-wc that you might find useful.
It essentially implements some basic javascript objects that allow you to get data from a kdb+ db via http or ws into a browser, put it into a table or draw a chart.
Queries can be parametrized by other html elements like selects, inputs and etc. It is very simple  - you need just to add a few tags (assuming kdb db allows access):

<kdb-srv fix-json="true"></kdb-srv> <kdb-query k-update-elements="tbl ch">([] time:.z.T+til[50]*00:00:10; price: 50?40*50?1.0)</kdb-query> <kdb-chart k-id="ch" k-style='width:800px;height:400px;'></kdb-chart> <kdb-table k-id="tbl"></kdb-table>

There are also kdb-editor (based on ACE editor) that can be used show or edit Q code and KDBLex that can be used to convert Q code to html.

I hope you find it useful!

WBR, Andrey Kozyrev.
