## Description
Ideom puts a real mind-map editor inside your WordPress admin. No external service,
no accounts, no iframes: maps are ordinary WordPress content, stored in your database,
protected by WordPress permissions, and embeddable in any post or page with a block
or a shortcode.
#### Made for thinking
* **A real canvas editor.** The whole map is drawn on an HTML canvas by a custom
React renderer, so dragging, panning and zooming stay smooth even on large maps.
* **Markdown in every node.** Headings, bold and italics, code, links, lists, quotes—
even tables.
* **Style it your way.** Color branches, change line styles and shapes, resize
nodes, drop sticky notes, and react to any node with emoji.
* **Keyboard first.** A command palette (Ctrl/Cmd+K), find node (Ctrl/Cmd+F), duplicate
branch (Ctrl/Cmd+D), and full undo/redo.
* **Templates.** Star any map as a template and start new maps from it.
* **Export.** Download any map as an SVG file.
#### Made for WordPress
* **Your data stays home.** Every map is a `ideom_map` post; the document is JSON
in post meta. Deactivating or deleting the plugin leaves your maps untouched,
and Tools Export can back them up.
* **Embed anywhere.** Use the Mind Map block or the shortcode below. Visitors get
the map read-only: they can pan, zoom, fold branches and export, and nothing
they do reaches the server.
* [ideom_map id=”42″ height=”600″]
* **Start from anywhere.** + New Mind Map in the admin bar opens a fresh map.
* **Sensible permissions.** A published map is readable by anyone — that is what
makes embedding worth doing. Everything else follows WordPress capabilities:
creating needs `edit_posts`, updating or deleting is re-checked on the server
for that specific map, and the map list is never public.
* **Its own REST API.** Maps are served through the plugin’s `ideom/v1` namespace,
and every write passes strict document validation. Core’s post endpoints are
deliberately not exposed.
Worth knowing before you write anything sensitive in a map: a published map is readable
by anyone who knows its post id, whether or not it is embedded anywhere. Keep private
notes out of published maps, or keep the map as a draft.
#### REST API
Namespace `ideom/v1`. Writes are authenticated with cookies plus the standard `X-
WP-Nonce` header; reading a published map needs neither.
* `GET /maps` — every map the caller may see, newest first, capped at 100
* `POST /maps` — create a map
* `GET /maps/` — read one map
* `PUT /maps/` — overwrite one map
* `PUT /maps//template` — star or unstar a map as a template
* `DELETE /maps/` — delete one map
Errors carry a stable code: `ideom_invalid_document` (400), `ideom_forbidden` (403),`
ideom_not_found` (404).
### Source Code
This plugin ships built JavaScript and CSS. The unminified source, and the tools
that build it, are public:
* Repository: https://github.com/theguriev/ideom
* Each release is built from the tag of the same version as `Stable tag`.
Where the shipped files come from:
* `assets/index.js` `apps/wordpress/src/main.tsx` (with `packages/engine` and `
packages/storage`), built by `apps/wordpress/vite.config.ts`
* `assets/block.js` `apps/wordpress/src/block.ts`, built by `apps/wordpress/vite.
block.config.ts` — a second, separate Vite build
* `assets/index.css` `apps/wordpress/src/index.css` (Tailwind)
To build it yourself you need Node 22 or newer and pnpm:
```
git clone https://github.com/theguriev/ideom
cd ideom
pnpm install
pnpm wp:package
```
That writes `services/wordpress/dist/ideom.zip`, which is this plugin.

## Installation
1. Install through Plugins Add New (search for “Ideom”), or upload the ZIP through
Plugins Add New Upload Plugin.
2. Activate the plugin.
3. Open **Ideom** in the admin menu and press **New**.
4. Embed the map anywhere with the Mind Map block or `[ideom_map id="…"]`.
## FAQ
### Does it need an account or an external service?
No. The editor runs entirely on your site and the plugin makes no external requests.
Maps never leave your database.
### Where is a map stored?
In a `ideom_map` post. The title mirrors the root node’s text; the document is JSON
in the `_ideom_content` post meta, alongside `_ideom_version` and `_ideom_template`.
### Can visitors edit an embedded map?
No. A signed-out visitor gets the map read-only: it can be panned, zoomed, folded
and exported, and nothing they do reaches the server. The same applies to any signed-
in user without `edit_post` on that map. Every write is re-checked on the server
regardless of what the front end believed.
### Does it expose the maps through the core REST API?
No. The post type registers with `show_in_rest` disabled on purpose — core’s endpoints
would let a client write `_ideom_content` without going through the plugin’s document
validation.
### What happens to a corrupted map?
It degrades to an empty document instead of breaking the screen. Content that fails
validation — non-finite coordinates, duplicate node ids, cyclic parent chains —
is never returned to the editor.
### What happens to my maps if I delete the plugin?
They stay. Maps are your content, stored as ordinary `ideom_map` posts, and deleting
or deactivating the plugin leaves them in the database untouched — reactivating
brings all of them back exactly as they were.
If you want them gone, delete them in the Ideom screen **before** removing the plugin;
once it is gone there is no screen that lists them. To keep a copy, Tools Export
offers “Mind Maps” as an export type.
Note that deleting a _user_ does delete their maps, the same way WordPress deletes
other content belonging to a removed user.
