EOS Tribe published JS Client library for Telos and Worbli Spectrum API endpoints:

Telos JS libraries:

• https://spectrum-client.s3.amazonaws.com/telos.spectrum.min.js
• https://spectrum-client.s3.amazonaws.com/telos.spectrum.js

Worbli JS libraries:

• https://spectrum-client.s3.amazonaws.com/worbli.spectrum.min.js
• https://spectrum-client.s3.amazonaws.com/worbli.spectrum.js

JS method signatures for both JS libraries:

• get_blocks(onMessageHandler, onCloseHandler, onErrorHandler)
• get_transaction(account, onMessageHandler, onCloseHandler, onErrorHandler)
• get_actions(account, actions, onMessageHandler, onCloseHandler, onErrorHandler)
• get_table_rows(account, table, scope, onMessageHandler, onCloseHandler, onErrorHandler)

Below is the sample use JS code for get_blocks method:

  Spectrum Demo


    var onMessageHandler = function (data) {
      console.log("Message: "+data);
    };
    var onCloseHandler = function(data) {
      console.log("Connection closed: "+data);
    };
    var onErrorHandler = function(error) {
      console.log("Error: "+error);
    };
    var websocket = get_blocks(onMessageHandler, onCloseHandler, onErrorHandler);
