Deciding message delivery to a specific user - need help with a sample/example

[vinayms01]

Hello, we have a use case where we want to send a message to a specific user depending on some logic in Data Adapter.
For examples if we when data adapter receives data { id=10, age=20 } it needs to go to user with id=10 only. Other connected connections should not receive that message.

Do we have a sample which shows this type of implementation. Most of the sample I saw were publishing to all connected users.

Hi vinayms01,

A typical example of Personal messages (unicast) is the "Basic Messenger Demo"; please find the full code from GitHub: https://github.com/Lightstreamer/Lig...ent-javascript
In this case each client subscribes directly to a personalized item:

https://github.com/Lightstreamer/Lig...ndex.html#L202

But an alternative could be that all clients subscribe to the same Item; but through the getItems method (https://sdk.lightstreamer.com/ls-ada...a.lang.String)) of the Metadata Adapter this is transformed into a personal item simply by adding a suffix (or prefix) identifying the user.
In your case could be the id.

Regards,
Giuseppe
