Some Watson services support CORS, others do not. However, when accessing over CORS, you must use an Auth Token rather than a username/password combination*.

This is a partial list of which services support CORS: https://github.com/watson-developer-cloud/node-sdk/tree/master/examples/webpack#important-notes

Here are a couple of examples using the Node.js SDK:

• Webpack: https://github.com/watson-developer-cloud/node-sdk/tree/master/examples/webpack
• Browserify: https://github.com/watson-developer-cloud/node-sdk/tree/master/examples/browserify

And, a whole host of examples with the Speech JavaScript SDK:

* There are a couple of services that use API keys rather than username/password combinations. In that case, you can use the API key directly from client-side code if the service supports CORS.
