GET /events

Protected. Requires a valid session cookie (credentials: 'include').

Subscribe to update signals (SSE)

Opens a Server-Sent Events stream for the authenticated user's selected company. Clients receive named signals when another request successfully mutates shared data for that company (including the same browser's other tabs).

Use EventSource with credentials so the session cookie is sent:

const es = new EventSource('https://…/api/events', { withCredentials: true });
es.addEventListener('category', () => { refetchCategoryTree(); });
es.addEventListener('articles', () => { refetchArticleIndex(); });
es.addEventListener('article-42000045', () => { refetchArticle('42000045'); });

Keep-alive comments (: keepalive) are sent roughly every 25s. Reconnect after changing the selected company (the stream is bound to the company at connect time).

Signals

Signal	Emitted after successful
category	POST /category, PATCH /category/{id}, PUT /category/order, DELETE /category/{id}, POST /category/{id}/image, DELETE /category/{id}/image
articles	POST /article, PATCH /article/{sku}, DELETE /article/{sku}
article-<sku>	PUT /article/{sku}/weight, PUT /article/{sku}/prices, PUT /article/{sku}/eans, PUT /article/{sku}/categories, PUT /article/{sku}/brand, PUT /article/{sku}/images/order, POST /article/{sku}/image, DELETE /article/{sku}/image/{fullHash}

Signals are only sent when the mutation actually succeeds (2xx). Failed or no-op validation errors do not emit. The article-<sku> event name uses the concrete SKU (e.g. article-42000045).

Response 200

SSE stream (text/event-stream). Each signal is an SSE event whose name is the signal id and whose data is {}.
