Starschema Tableau Web Table Connector (WDC) Toolkit / ConnectorBase 
Starschema's Tableau Web Table Connector Toolkit enables you to develop Web Data Connectors in CoffeeScript more easily, elegantly. It comes with sample connectors for SAP BusinessObjects. Twitter, MongoDB, Github and generic CSV.
The framework (or as we call ConnectorBase) has a few concepts that may feel different to the usual WDC development process:
-
A connector is built from a number of states/steps (like setup, authentication, running the connector), where each state/step has a separate representation in the UI (like a setup page, an authentication page, etc.)
-
The form inputs used by the connector are declared in the template for each state (instead of declaring them in the connector code itself), so you can keep your connector code DRY
-
The connector source code defines the JavaScript to be ran during transitions from one state to another. (like get the data from all the inputs and call tableau.submit() when transitioning from the start state to the run state.)
Business Objects connector
Building the connector
You should never trust any tableau connector on the internet. Check the source codes before you deploy or run anything on your environment. Therefore we don't provide any "prebuilt" connector, you should do it for yourselves.
Linux / OSX
npm install
./build-sap-bo.sh
Windows
npm install
./build-sap-bo.bat
this copies the resources and builds the client using browserify. For more information on how to use SAP BusinessObjects connection check out this article.
Running the BO proxy web service
coffee coffee/sap_bo/proxy_server.coffee
Then navigate to http://localhost:3000/sapbo.html in the
Simulator / Tableau.
Building the twitter client
npm install
./build-twitter.sh
this copies the resources and builds the client using browserify.
Running the twitter client / server
coffee coffee/twitter_connector/twitter_auth_server.coffee
Then navigate to http://localhost:3000/twitter.html in the
Simulator / Tableau.
Building the mongo/raw json client
Connecting to mongodb using the Simple REST API requires starting the
mongod server with the --rest and --jsonp command line
switches to enable the REST API and enable the connector to load data
through JSONP.
For example on Ubuntu this may mean:
mongod --config /etc/mongodb.conf --rest --jsonp
To access the REST API from a different machine you also need to change
the bind_ip configuration property in your mongodb configuration
form 127.0.0.1 (the default that comes with most mongodb packages) to
0.0.0.0
After changing the bind address, starting mongod will issue a warning:
warning: bind_ip of 0.0.0.0 is unnecessary; listens on all ips by default
but this warning is a lie when it comes to the web interface used for the REST API.
Then build the mongodb connector:
./build-mongodb.sh
this copies the resources and builds the client using browserify and
places the results in the dist folder.
Then fire up a web server in the dist directory and the mongodb
connector should be accessible with mongodb.html.
