Connect to external SQLite database by plotly.js

I’d like to include some plots on my web page. The data for these plots are stored in a SQLite file, stored on Dropbox (S3, other clouds, never mind). Is there a native support in Plotly.js to connect and run queries to a cloud-stored SQLite? Or if not, are there other methods how I can connect and run queries to get my data (i.e. javascript connector)?
