Ditto JavaScript Node.js client

Implementation of the Eclipse Ditto JavaScript API that uses functionality of a Node.js environment, e.g. Buffer.

It is published to the npm registry as CommonJS module.

Building

Basically it makes sense to trigger the build process once from the parent module. Then you'll be able to use the default build process in here:

npm install
npm run build
npm run lint
npm test
# or npm run test:watch

Using

npm i --save  @eclipse-ditto/ditto-javascript-client-node

Create an instance of a client:

const domain = 'localhost:8080';
const username = 'ditto';
const password = 'ditto';

// could also use newWebSocketClient() for the WebSocket implementation
const client = DittoNodeClient.newHttpClient()
            .withoutTls()
            .withDomain(domain)
            .withAuthProvider(NodeHttpBasicAuth.newInstance(username, password))
            .build();

To use a path other than /api to connect to ditto, the optional step .withCustomPath('/path/to/api') can be used.

To find out how to use the client, have a look at the api documentation, since the API will stay the same no matter what implementation is used.

Proxy

The Node.js implementation supports setting up a proxy. Currently, it supports either reading directly from 'https_proxy' (or 'HTTPS_PROXY') environment variable or manually setting the proxy settings.

// may also omit one or more of the options
const proxyOptions = {
  url: 'PROXY-URL:PROXYPORT',
  username: 'PROXY-USERNAME',
  password: 'PROXY-PASSWORD'
}

DittoNodeClient.newHttpClient(proxyOptions)
//  ...

Any options that are set manually will override options that are read from an environment variable.
