Tsconfig Alias Image Resolver

Resolve @/… style path-alias image references (from tsconfig.json compilerOptions.paths) in real time, so images render in Obsidian reading view and live preview — without modifying your notes on disk.

Why

Astro / Vite projects (e.g. Astro Paper) reference images with aliases like ![alt](@/assets/images/example.jpg). Obsidian does not understand the @ alias, so the image shows as "file not found". This plugin reads the vault's tsconfig.json and rewrites those paths at render time.

Features

• Reads compilerOptions.paths from the vault-root tsconfig.json (e.g. { "@/*": ["./src/*"] } → @/ → src/).
• Rewrites rendered <img> elements and Obsidian internal-embed placeholders in real time (markdown post-processor + MutationObserver), in both reading view and live preview.
• Never edits note files on disk — everything happens in the render layer.
• Auto-reloads when tsconfig.json changes; also provides a "Reload tsconfig aliases" command.
• Non-alias relative paths that Obsidian fails to resolve are additionally tried as vault-root paths.

Install

1. Build the plugin (see below).
2. Copy main.js and manifest.json into <your-vault>/.obsidian/plugins/tsconfig-alias/.
3. Enable Tsconfig Alias Image Resolver in Settings → Community plugins (disable Restricted mode if needed).

Development

npm install
npm run build   # bundles src/main.ts and outputs main.js to the repo root

npm run dev starts esbuild in watch mode (output goes to the repo root).

Requirements

• Obsidian v1.0+
• A tsconfig.json at the vault root with compilerOptions.paths
