Cube.js, which acts as a middleman between your database and analytics dashboard, can provide a real-time WebSockets-based API for the front end while polling the database for changes in data. It also enables richer analysis, such as quantiles and histograms of arbitrary event sets. Pick your favorite framework, charting library, and UI kit—the template will wire it all together and configure it to work with the Cube.js backend. Just a learning experiment cobbled from pieces of this excellent websockets tutorial and these excellent d3 tutorials. By collecting events rather than metrics, Cube lets you compute aggregate statistics post hoc. Cube is built on MongoDB and available under the Apache License. Cube.js templates are open-source, ready-to-use frontend analytics apps. It also enables richer analysis, such as quantiles and histograms of arbitrary event sets. Dependencies $ npm install websocket Setup. Update this line of index.html to wherever the websocket server is running:
The data can be passed in both directions as “packets”, without breaking the connection and additional HTTP-requests. WebSocket is especially great for services that require continuous data exchange, e.g. Cubeis a system for collecting timestamped events and deriving metrics.
D3/Websockets Experiment Overview. Cube.js Playground can generate a boilerplate frontend app. The WebSocket protocol, described in the specification RFC 6455 provides a way to exchange data between browser and server via a persistent connection. Ubuntu 14.04 with newly installed nodejs npm mongodb Install cube by npm install cube and it throws the errors： npm ERR! Cube is a system for collecting timestamped events and deriving metrics. By collecting events rather than metrics, Cube lets you compute aggregate statistics post hoc. a convenient way to start developing a dashboard or analytics application. You can select your favorite frontend framework and charting library and Playground will generate a new application and wire all things together to work with the Cube.js backend … Cube works great with Cubism, our JavaScript library for visualizing time series. It is easy to get started and completely customizable down …
