Getting Started Examples

Solace Node.js API

The "Getting Started" tutorials will get you up to speed and sending messages with Solace technology as quickly as possible. There are three ways you can get started:

• Follow these instructions to quickly spin up a cloud-based Solace messaging service for your applications.
• Follow these instructions to start the Solace VMR in leading Clouds, Container Platforms or Hypervisors. The tutorials outline where to download and how to install the Solace VMR.
• If your company has Solace PubSub+ Event Brokers deployed, contact your middleware team to obtain the host name or IP address of a Solace PubSub+ Event Broker to test against, a username and password to access it, and a VPN in which you can produce and consume messages.
