VAN Enhancement Suite

A browser extension that speeds up list building and GOTV turf cutting in VAN.

A Chrome and Firefox extension, built in-house for campaign staff, that reworks the parts of VAN they use most when building lists and cutting turf for get-out-the-vote.

What it does

The hard part

VAN’s pages aren’t a public API, so the extension has to work with them without breaking them. It drives VAN’s own widgets the way a click would, rather than editing the form data they submit, so VAN does its own bookkeeping. Locked controls are blocked from changes but never disabled, because a disabled checkbox isn’t submitted with the form, which would silently drop a suppression from the search. And if VAN changes a page and something expected isn’t there, the extension leaves the page untouched instead of hiding a control it can’t replace.

The precinct table is generated from a BigQuery export at build time, so the extension holds no credentials and queries nothing while it runs.

Built with

JavaScript (Manifest V3), with Node and Python build tools for the precinct table, icons, and signed Chrome and Firefox releases.
