Getting Started Examples

Solace JavaScript 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 PubSub+ software event broker in leading Clouds, Container Platforms or Hypervisors. The tutorials outline where to download and how to install the Solace PubSub+ software event broker.
• 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.

Checking out

To check out the project, clone this GitHub repository:

git clone https://github.com/SolaceSamples/solace-samples-javascript
cd solace-samples-javascript

Note: the code in the master branch of this repository depends on Solace JavaScript API version 10 or later. If you want to work with an older version clone the branch that corresponds your version.

Download the Solace JavaScript API

These samples depend on version 10 or later of the Solace JavaScript API library.

The Solace JavaScript API library can be downloaded here. The instructions in this tutorial assume you have downloaded the Web Messaging API for JavaScript library and unpacked it to a known location. The samples assume a lib directory containing the API libraries will be installed in the current solace-samples-javascript directory at the root of the cloned repo:

cp -R <path_to_unzipped_API_distribution_package>/lib .

Running the Samples

The samples are found in the src/basic-samples and src/features directories. Each sample is in it's own subdirectory. Within each sample subdirectory there is an html file which you load to launch the sample.

For example the TopicPublisher is found here: src/basic-samples/TopicPublisher

And it is launched by running the following in your browser:

TopicPublisher.html
