The Web Data Connector version 3.0 is a complete rewrite of the web data connector model used in previous versions. Web Data Connector 3.0 offers you extended flexibility and a streamlined toolset to create connectors for web-based data that isn’t easily retrieved using conventional ODBC or JDBC drivers. With the Web Data Connector 3.0 SDK, you can build connectors to virtually any web data source faster and more easily than ever before.
The Web Data Connector 3.0 framework revamps the web data connector developer experience by eliminating the hosting overhead of the earlier versions. This gives integrated authentication capabilities and modernizes the SDK tools, libraries, and API. These changes reduce the complexity for building a new web data connector.
Also, with the new framework, web data connectors appear as named connections in Tableau and can be distributed through Tableau Exchange. This makes the connectors more discoverable and usable across the Tableau platform.
We created the TACO Toolkit to help you develop your connectors. The TACO Toolkit is an npm package. The toolkit contains a CLI, a software development kit (SDK), and the Extensible Protocol Server (EPS).
The TACO CLI provides a global way to create and build a TACO project that contains your connector source code. The CLI can also pack a built TACO project into a Tableau TACO connector (the
The TACO SDK provides application programming interfaces (APIs) to help you develop your TACO projects (the source code). The SDK also provides some npm scripts, which allow you to build and test your projects with the standard npm commands.
The EPS is started by the TACO CLI or the npm scripts to load and test your connector source code.connector.
