It is a WYSIWYG HTML editor on TipTap (ProseMirror, MIT) with a Source tab that shows and edits the exact HTML string. The toolbar offers paragraphs and headings 2 to 4, bold, italic, bullet and ordered lists, links, blockquotes, tables, images, YouTube embeds, a raw HTML block, undo and redo. Labels follow the `ui-locale` attribute (`en`, `pl`). + +The element follows the admin field type element contract: the `value` property holds the HTML string; the attributes are `field-name`, `record-id`, `locale`, `ui-locale`, `options`, `disabled` and `invalid`; a bubbling `summer-change` event with `detail.value` fires on user edits only. It styles itself only through the admin `--c-*` variables, in `blogeditor.css` under its tag (TipTap's injected stylesheet is off), and never receives or sends credentials. + +- **Untouched values.** The element returns the exact string it was given until the user edits; an untouched imported post is saved byte for byte. Setting `value` to the string it currently returns is a no-op. After an edit, top-level blocks that are still equal to the loaded ones keep their original bytes, so editing one paragraph changes only that paragraph. Markup the schema does not model (`footer`, `section`, `aside`, `header`, `nav`, `details`, `style`, `div` and similar blocks, and a `figure` that is not an image with an optional caption) becomes a raw HTML card that shows its source as text and is written back verbatim. Unmodelled attributes on paragraphs, headings, lists, blockquotes, tables, cells, images and links, and `span` elements with attributes, survive an edit; event handler attributes (`on*`) are never kept. +- **Embeds.** The embed button takes a YouTube URL (`youtube.com/watch?v=`, `youtu.be/`, `youtube.com/shorts/`, `youtube.com/embed/`) and stores exactly `
`, where `ID` matches `^[A-Za-z0-9_-]{11}$`. The admin shows a card and never an iframe; the site layer expands the placeholder. Another provider is one entry in `EMBED_PROVIDERS` (`embed.ts`) and one in the layer. +- **Links.** The editor creates and keeps links only to `http`, `https`, `mailto` and relative URLs (`isPolicyUrl` in `extensions.ts`), the schemes both sanitizer policies keep; the scheme is read after removing control characters and spaces. A created link has `href` only; stored links keep their own `target` and `rel`, which the server strips on an edited save. +- **Images.** An image chosen with the file picker (JPEG, PNG, GIF, WebP) or dropped on the editor is handed to the admin page as a bubbling `summer-upload` event with `detail {id, file}`. The admin uploads it with its own session and answers on the element with `summer-upload-result` `{id, url}` or `{id, error}`. On a URL the editor asks for the alt text (required) and an optional caption and inserts ``, or `
` with `` and `
` when a caption is given. An error, or no answer within 60 seconds, is shown in the status line and nothing is inserted. +- **Sanitizing.** The element never sanitizes. Every admin save goes through `classes.SanitizeHTML`, which strips what the policy does not allow. + +The element is built by the plugin's own JS build into `assets/dist/blogeditor.js` and `assets/dist/blogeditor.css`. Both files are committed and embedded through `admin.go`, so a host application needs no Node: + +```sh +npm ci # exact versions from package-lock.json +npm run build # typecheck, then vite build into assets/dist +npm test # vitest on happy-dom +bash scripts/check-dist.sh # fails when assets/dist differs from a fresh build +``` + +After changing `assets/src`, run `npm run build` and commit `assets/dist`. + +`tests/blogeditor/fixtures/editor-corpus.json` holds the editor's own output, built through editor commands: an embed, images with and without a caption, a table with a header row, links, headings, lists (one starting at 3), a blockquote, inline marks, a code block, a horizontal rule, a hard break, and one document combining them. `tests/blogeditor/corpus.test.ts` rebuilds it and fails when the committed file differs; `UPDATE_CORPUS=1 npm test` rewrites it.
