Spike is a collection of JavaScript modules, compilers, and libraries intended to ease development of front-end applications that interact with web services.

Spike uses these dependencies to implement the following features within a well defined architecture:

• Polymorphic models and state manager framework to retrieve data on the server or the client.
• Server-side rendering on Express server which bypasses initial render and data retrieval on the client.
• Client-side management of browser history (e.g., routing).
• Webpack development server for fast and easy development of changes through hot loading.
• Webpack configuration for environment based API calls (see client/api/{env}).
• Standalone Webpack builds for offline development of HTML and CSS by designers.
• Karma and Jasmine configurations to test app rendering on both client and server.
• ESLint configuration to ensure consistent code style with Spike base.

A system that consists of a web server, TCP server and multiple distributed clients that connect to the TCP server and do the work. The HTTP server gets the request from the app (a URL to be scraped). It passes the request to the TCP server via shared memory, a channel that does the load balancing awarding the work to one of the connected workers. Workers are on servers in different parts of the world. To minimize latency and fetch the page, send it over TCP to the server, which then responds to the HTTP server which, in turn, returns the page content as the result.
