+# Basic Episodes Fetch
+
+## Overview
+This plan focuses on adding a minimal **episodes‑fetch** feature that pulls podcast episodes from the CommaFeed backend
+using environment variables for configuration.
+
+The plan is derived from:
+- `docs/dev/README.md` (API endpoints, authentication)
+- `src/` structure and existing route system
+- Build scripts in `bs/` – only linting is required at this stage.
+
+## Tasks
+1. **API client** (DONE)
+	- Adds `src/api` folder to the project structure (update also @src/README.md).
+	- Implement a lightweight wrapper around `fetch` in `src/api/fetchAPI.ts`.
+	- Build `authHeader()` that returns the Basic‑Auth header using for now hardcoded vars.
+1. **Episode service** (DONE)
+	- Add `src/api/episodes.ts` with `getEpisodes(feedId)` and `getEpisode(id)`.
+	- Add data types
+	- Use `/rest/feed/entries?feed_id=${feedId}` endpoint.
+1. **Page update** (TODO)
+	- Add fetching all episodes
+	- Update `<app-episodes>` to reflect loading state(s).
+	- Add episode list item component.
+	- Update `<app-episodes>` to render the episode list received from the route context.
+1. **Testing** (TODO)
+	- Add unit tests for `api/*.ts` using project test setup.
+	- Add unit test for created component(s)
+1. **Linting** (TODO)
+	- Ensure all new files satisfy the lint rule defined in `bs/dev/lint`.
+
+## Expected Output
+- Visiting `/episodes/` will display a list of episodes fetched from CommaFeed.
+- Episodes are identified by their `id` and displayed with title, publish date, and an audio link if available.
+- Authentication uses the env variables; no credentials are hard‑coded in source.
+
+---
+
+> **Note**: This plan intentionally keeps external dependencies minimal. It can be extended later for pagination, caching, or offline support.
