From 9c3de8232b803df78ed5141a119023490ad5daaa Mon Sep 17 00:00:00 2001 From: rohitagarwal-sp18 Date: Thu, 2 Jul 2026 12:25:42 +0530 Subject: [PATCH 1/4] feat: add `codegraph view` interactive graph command MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Renders the index as a zoomable, searchable HTML graph (nodes colored by kind, sized by degree). vis-network is bundled and inlined so the page works fully offline — no CDN — matching CodeGraph's local-first design. `--open` serves it on a loopback port and opens the browser. Data assembly lives in src/graph/viewer.ts and is exposed via a narrow typed CodeGraph.getGraphView(), keeping the raw SQLite handle private.
