kandi X-RAY | stompjs Summary
This repository is for version 5 and above of this library. Lower versions are not supported any longer. This library allows you to connect to a STOMP broker over WebSocket. This library supports complete STOMP specifications including all current protocol variants. Most popular messaging brokers support STOMP and STOMP over WebSockets either natively or using plugins. In general JavaScript engines in browsers are not friendly to binary protocols, so using STOMP is a good option because it is a text-oriented protocol. This library has its roots in a version released by Jeff Mesnil.

I have a problem with pigeon-maps in my reactjs-app. Using the mouse to navigate through the map works fine, but zooming with the scroll wheel does not work. However, a double-click zooms in the map, but then i have no way of zooming out again.
zoom and center are controlled variables.
...ANSWER
Answered 2020-Dec-07 at 13:27According to pigeon-maps docs, you need to press (cmd/win) key while zooming with the mouse wheel
metaWheelZoom - Zooming with the mouse wheel only works when you hold down the meta (cmd/win) key. Defaults to false.

Answered 2020-Oct-05 at 03:24In order to use hooks, you should convert your class into functional component. I assume you don't know about hooks and functional components.
This blog will help you understand the nuances of the conversion -> https://nimblewebdeveloper.com/blog/convert-react-class-to-function-component
Secondly, you need to know how hooks works. Refer to this -> https://reactjs.org/docs/hooks-intro.html
QUESTION
I'm trying to send some data from React.js to Spring Boot using STOMP.
I have this setup in server side :
...ANSWER
Answered 2020-Jul-10 at 16:04Because Stomp send(destination, headers, body) expects the body of type String. So you need to convert to String by doing JSON.stringify({data: this.state.data}). And of course, your server should contain a model matches that.
QUESTION
I have been researching for a way to limit the number of clients who can subscribe to a specific stomp topic but have not yet understood, which could be the right approach according to my needs.
My use case is a game, which I am developing in Angular (ng2-stompjs stomp client) and Spring Boot Websockets (for the moment, the Spring in-memory message broker is in use).
The idea is that a user can be connected and subscribed to a "/lobby" stomp topic, and there he sees the opened game rooms, that could be in different statuses. for example, in-play or not started yet due to the low number of players joined. I'd like to intercept and programmatically restrict a possible subscription of a client, to a specific "/room/{roomId}" topic, IF the MAX number of players has been reached, for example, 4. There could also be some simple client-side validation to restrict that, but I believe only client-side is not sufficient
So my main questions are: How can a specific stomp topic subscription be intercepted in Spring? Is it possible to return to the client-requestor some kind of error message that subscription could not be done?
I'd really appreciate your help, thank you in advance!
...ANSWER
Answered 2020-Jun-29 at 04:23You could implement a StompEventListener which listens for subscriptions, in this we can have map mapping a destination(room number) versus the count of number of players in that particular room. if the count is already at max reject the subscription.
