})Node.js Integration
Node.js is an open source event driven runtime that can be integrated with Teiid Spring Boot.
Prerequisites
-
Have Node.js installed. The npm pagckage pg is also required. Use "
-
Your Teiid Spring Boot installation should already be setup for ODBC access. This allows the optional compatibility with Node.js for PostGIS/PostgreSQL to be used.
Usage
For example if you have VDB called "northwind" deployed on your Teiid Spring Boot server, and it has table called "customers" and you are using default configuration such as
user = 'user' password = 'user' host = 127.0.0.1 port = 35432
