🎉 Self-contained: CodeGraph bundles its own runtime — install anywhere, on any Node (or none)

No more database is locked. No more native build failures. No more "WASM fallback active."

CodeGraph used to need better-sqlite3, a native module compiled against your exact Node version. When that build failed (common on Windows and locked-down machines) it silently dropped to a slow WASM SQLite build with no WAL — the root cause of the intermittent database is locked errors on concurrent MCP tool calls (#238). That entire class of problem is gone: CodeGraph now ships a self-contained Node runtime and uses Node's built-in node:sqlite (real SQLite, full WAL + FTS5).

• ✅ Zero native compilation — nothing to build, ever; nothing to rebuild when Node changes.
• ✅ Runs on any Node version — or with no Node at all. Install via the standalone installers with no Node present, or keep using npm/npx on any version (your Node only launches the bundled runtime).
• ✅ database is locked fixed at the root — real WAL means readers never block on a writer.

• ⚡ 5–10× faster than the old WASM fallback for anyone who was stuck on it.

  :::bash

  macOS / Linux — no Node required

  curl -fsSL https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.sh | sh

  Windows (PowerShell) — no Node required

  irm https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.ps1 | iex

  or, if you have Node (any version):

  npm i -g @colbymchenry/codegraph

Added

• Standalone installers — one-line install with no Node.js required: curl -fsSL .../install.sh | sh (macOS/Linux) and irm .../install.ps1 | iex (Windows). They fetch the matching self-contained bundle from GitHub Releases and put codegraph on your PATH.
• Lua: CodeGraph now indexes Lua (.lua) — functions, methods (table t.f and t:m definitions become methods with a t::f receiver-qualified name), local variables, require(...) imports, and the call edges between them. Querying a Lua project (Neovim plugins, Kong, OpenResty, game code) now surfaces its modules, methods, and call graph.
• Luau (#232): CodeGraph now indexes Luau (.luau), Roblox's typed superset of Lua — everything Lua extracts, plus type / export type aliases, typed function signatures, generics, and Roblox instance-path require(script.Parent.X) imports.

Changed

• SQLite backend is now Node's built-in node:sqlite (real SQLite, WAL + FTS5), shipped inside a bundled Node runtime. This fixes the concurrent-read database is locked errors (#238) at the root and removes the native build step entirely.
• npm i -g / npx now install a self-contained bundle. The main package is a tiny shim; the runtime ships as per-platform optionalDependencies, so the install works on any Node version (your Node only launches the bundle).
• codegraph status now reports the effective journal mode (wal vs not), so a database is locked report is triageable at a glance.

Removed

• better-sqlite3 (optional native dependency) and node-sqlite3-wasm (WASM fallback) — along with the native-build banner, the WASM fallback path, and the no-WAL lock retries they required. The dependency tree now has zero native addons.

Fixed

• Installer: re-running codegraph install now removes the broken auto-sync hooks that pre-0.8 versions wrote to Claude Code's settings.json. Those builds added a Stop → codegraph sync-if-dirty hook (and a PostToolUse → codegraph mark-dirty partner); both subcommands were later removed from the CLI, so Claude Code reported Stop hook error: ... unknown command 'sync-if-dirty' on every turn. The cleanup is surgical — only codegraph's own hook entries are stripped, so unrelated hooks sharing the same file or event (e.g. a GitKraken gk ai hook run hook) are left untouched — and it also runs on uninstall, so the npm preuninstall step fully reverses a legacy install. Re-run codegraph install once on an affected machine to clear the error.
