JavaScript library for the development of Lightstreamer JMS Extender clients running inside the web browser
The Lightstreamer JMS Extender Web Client enables any JavaScript application running inside the web browser to act as a JMS client, that is, ready to connect to a JMS broker via Lightstreamer JMS Extender.
The library is designed to be as class-by-class and method-by-method equivalent to JMS API 2.0 as possible.
The library is available as npm package, so you can download and install it through:
npm install lightstreamer-jms-web-client
Then load it from local node_modules:
<html>
<head>
<script src="./node_modules/lightstreamer-jms-web-client/dist/lightstreamer-jms.js"></script>
...
</html>
The library is also available on unpkg, to which you can point directly in the script tag:
<script src="https://unpkg.com/lightstreamer-jms-web-client@2.0.0-b1/dist/lightstreamer-jms.js"></script>
Open a session against Lightstreamer JMS Extender, create a Topic Connection and connect to the JMS broker:
jms.TopicConnectionFactory.createTopicConnection("http://localhost:8080/", "HornetQ", null, null, {
onConnectionCreated: function(conn) {
var topicSession = conn.createSession(false, "PRE_ACK");
.....
conn.start();
}
});
Create a Topic Subscription and send it to the broker:
var topic = topicSession.createTopic("stocksTopic");
var consumer = topicSession.createConsumer(topic, null);
Listen for messages:
consumer.setMessageListener({
onMessage: function(message) {
var feedMessage= message.getObject();
var key= feedMessage.itemName;
var values= feedMessage.currentValues;
console.log(values["stock_name"] + ": " + values["last_price"]);
}
});
