It may be obvious for some, but after reading How are the most popular frameworks growing year over year I decided to put together a query to get stats for a single JavaScript framework, separated by months:
SELECT
COUNT(DISTINCT(pageid)) COUNT,
MONTH(SEC_TO_TIMESTAMP(startedDateTime)) month
FROM
(TABLE_QUERY([httparchive:runs], 'REGEXP_MATCH(table_id, r"^2014.*requests")'))
WHERE
REGEXP_MATCH(url,
r'angular')
GROUP BY month
ORDER BY month
This will give the evolution of a given framework for 2014. As new months appear, they will get added to the resulting table.
This is not entirely reliable, as it depends heavily on traffic: all JS frameworks (well I have confirmed with jquery and Angular) display a valley associated to a decrease in overall traffic in December and summer. This is the chart for Angular:
The query can be changed to display the last 12 /18 / whatever months.
