Development

npm ci
npm run format
npm run check
npm run build

Run npm run format after edits and before npm run check so Prettier-only issues are fixed upfront. npm run check runs TypeScript type checking, unit tests, ESLint, Prettier check, and a production esbuild bundle. The local npm run check path runs checks in parallel and uses ESLint's local cache. Use npm run check:ci when you need to reproduce the sequential, non-cached CI validation path.

main.js, data.json, and node_modules/ are ignored by Git. main.js is still the file Obsidian loads, so run npm run build or npm run build:prod after source changes.

Source Layout

The source tree is organized by responsibility rather than by the original single Obsidian plugin entrypoint:

  • src/main.ts registers Obsidian views, commands, settings, and lifecycle hooks.
  • src/app-server/ owns app-server transport, connection lifecycle, compatibility helpers, and RPC facades.
  • src/features/chat/ owns the main Codex chat surface: Obsidian ItemView classes, panel orchestration, request/app-server controllers, composer behavior, display models, chat-only UI renderers, approvals, user input, thread actions, and panel-specific state.
  • src/features/threads-view/ owns the dedicated Obsidian thread list view, including app-server thread list rendering and live open-panel snapshot aggregation.
  • src/features/selection-rewrite/ owns the Markdown editor selection rewrite command, popover, prompt/output handling, and ephemeral rewrite thread runner.
  • src/runtime/ owns Codex runtime configuration projection, model metadata, collaboration mode, and compact labels used by views.
  • src/shared/ contains feature-neutral helpers, including reusable DOM pieces and unified diff display helpers shared by chat and selection rewrite.
  • src/settings/ contains Obsidian settings models, settings-tab rendering, and app-server-backed dynamic settings data.
  • src/domain/threads/ contains thread title, reference, and archive export helpers shared outside the chat feature.

Keep new code near the state or API it owns. Feature code should not import from another feature directly; move shared behavior to src/shared/, src/domain/, src/app-server/, or src/runtime/ when more than one feature needs it.

Codex Panel's runtime UI is React-owned. Keep chat panel UI, the Threads view, and the selection rewrite popover in React components. Imperative DOM writes are limited to explicit bridge modules or Obsidian-owned API boundaries such as MarkdownRenderer, diff rendering, icon rendering, SuggestModal, and the Obsidian Setting-based settings tab. ESLint enforces this boundary with allowlisted bridge files; add a new allowlist entry only when the code is genuinely bridging an external DOM API.

React is pinned to 18.x for Obsidian Community plugin review compatibility. React DOM 19 currently bundles runtime code that creates <script> elements, which is flagged by Obsidian's automated review even though Codex Panel does not dynamically load external scripts. Revisit this pin only after Obsidian's review tooling can distinguish that React runtime code from plugin-controlled script injection.

App-Server Bindings

The app-server TypeScript bindings in src/generated/app-server/ are generated from the installed Codex CLI:

npm run generate:app-server-types
npm run check

The generation script uses codex app-server generate-ts --experimental because the panel depends on experimental app-server fields such as collaboration mode and generated v2 types.

API Baselines

Use the local API baseline report when checking whether the development environment matches the supported API policy:

npm run api:baseline
npm run api:baseline:check

Obsidian API compatibility follows semver within the guaranteed minor. manifest.json and versions.json define the minimum supported Obsidian app minor with a .0 patch version, while the obsidian npm dev dependency tracks the latest patch in that same minor using a ~ range. When the Obsidian API minor is raised, update manifest.json, versions.json, README requirements, and the obsidian dev dependency together.

Codex app-server compatibility is managed by Codex CLI minor version. README records the tested Codex CLI patch version, and the baseline check verifies that the local codex --version is in the same minor before app-server binding or compatibility work.
