Can client set custom payload to choose its own subscriptions ? #458

Closed yobud closed 3 years ago

yobud commented 3 years ago

Hi!

I'm thinking about how to integrate mercure into a large marketplace app.

Imagine it does have plenty of Stores, with plenty of Products. I'm a Customer and I have added 50 Products in my cart, from various Stores.

I want to know when any of these Products has it price changed by the store owner.

Wouldn't be inefficient and slow to have 50 EventSources (one for each product) ?

I could subscribe on /products but then, if I have more than 50k products which are constantly modified by store owners, wouldn't it be a waste of data exchanges (and perfs on client side to analyse 50k editions to know if Customer is concerned) ?

Wouldn't it be great for my user to send his own payload to subscribe to a batch of products. And just close and reopen an EventSource when he adds a product to his cart (to add it in payload) ?

The only way I see to make this work is to send a request to my server with these subscriptions urls, which would return a specific token to be used as mercureToken.

Is this the way to do or is there something already developed for such case ?

Thank you
