    Use API

    npm install --save glouc-pubsub-kafka-connect
    

    pubsub -> kafka

    const { runSourceConnector } = require("glouc-pubsub-kafka-connect");
    runSourceConnector(config, [], onError).then(config => {
        //runs forever until: config.stop();
    });

    kafka -> pubsub

    const { runSinkConnector } = require("glouc-pubsub-kafka-connect");
    runSinkConnector(config, [], onError).then(config => {
        //runs forever until: config.stop();
    });

    kafka -> pubsub (with custom topic (no source-task topic))

    const { runSinkConnector, ConverterFactory } = require("glouc-pubsub-kafka-connect");
     
    const etlFunc = (messageValue, callback) => {
     
        return callback(null, {
            id: messageValue.payload.id,
            name: messageValue.payload.name,
            info: messageValue.payload.info
        });
    };
     
    const converter = ConverterFactory.createSinkSchemaConverter({}, etlFunc);
     
    runSinkConnector(config, [converter], onError).then(config => {
        //runs forever until: config.stop();
    });
     
    /*
        this example would be able to store kafka message values
        that look like this (so completely unrelated to messages created by a default SourceTask)
        {
            payload: {
