Chapter 2. Installing the circuit breaker add-on from the Red Hat customer registry

Procedure

1. On the command line, access the root directory of your Node.js application.

2. To specify the download paths for installing Node.js modules, complete the following steps:

   1. In the root directory of your application, create a file named .npmrc.

   2. To specify the path to the Red Hat customer registry, enter the following line in the .npmrc file:

      @redhat:registry=https://npm.registry.redhat.com

   3. To specify the path to the npm registry, enter the following line in the .npmrc file:

      registry=https://registry.npmjs.org

   4. Save the .npmrc file.

3. To download and install the @redhat/opossum module, enter the following command:

   $ npm install @redhat/opossum

Verification

1. If a node_modules directory already exists in your project, the @redhat/opossum module is automatically installed in this directory.
2. If a node_modules directory does not exist in your project, a node_modules subdirectory is automatically created in the root directory of your Node.js application, and the @redhat/opossum module is automatically installed in this subdirectory.
