SODA for node.js is now part of the Oracle node.js driver, release 3.0 (and above).
To get started, download the latest Oracle node.js driver with 18.3 and above instant client. You'll also need an 18.3 and above Oracle Database (one good option for trying it out is to download the newly released free Oracle Database Express edition, which is geared toward developers).
Check out an excellent video by Dan McGhan and Anthony Tuininga covering the basics here.
User-guide is here.
