This is a project that aims to implement a client for showing web based graphs in wall monitors.

The client is an electron application that reads a configuration an opens as many browser windows as specified in it.

The client reads the configuration from a YAML file that is provided either through the local file system or through an HTTP POST request to the web server listening on port 8080. This makes updating the configuration of any wall monitor in the system trivial.

The following is an example request using curl:

curl -v -X POST "http://localhost:8080/load" --data-binary @config.yml

Each screen has a number of URLs that it will show with a specific layout. Current available layouts are carrousel and splitted.

The carrousel layout has a single configuration value called time, which determines for how long a specific URL is shown on screen before rotating to the next one. The value is an integer which represent the amount of milliseconds.

The splitted layout also has a single configuration value called orientation, which determines if the screen will be splitted in the vertical or horizontal direction.

The following is an example of what a configuration would look like in YAML:

- name: "Screen 1"
  pages:
    - url: "http://google.com"
      zoom: 0.5
    - url: "http://github.com"
      code: "alert('hello world!');"
  layout:
    name: splitted
    orientation: vertical

- name: "Screen 2"
  pages:
    - url: "http://lanacion.com.ar"
    - url: "http://stackoverflow.com"
  layout:
    name: carrousel
    time: 5000

- name: "Screen 3"
  pages:
    - url: "http://twitter.com"
    - url: "http://start"
  layout:
    name: carrousel
    time: 10000
