This assumes you are familiar with Node.js node-vault. If not, check out my article Getting Started with Node.js node-vault.

This assumes the following has already been done.

• Hashicorp Vault has been installed

Here is how you can return health status of Hashicorp Vault.

var options = {
  apiVersion: 'v1',
  endpoint: 'http://vault.example.com:8200',
  token: 'hvs.CAESIAfdfIXuyXbXZCaDx7kSXpC04y4yPRhbTulQBGinXzbsGiUKHGh2cy5sb2lQZVFnRWVxQjdxak8yTkZUNVJUd0sQmM6ACRgI'
};

var vault = require("node-vault")(options);

vault.health()
    .then(console.log)
    .catch((err) => console.error(err.message));

Something like this should be returned.
