Dependencies

• npm
• bower
• grunt-cli
• Sass (>= 3.2)

Installing dependencies

Install npm and Sass with your package-manager. On Debian-like systems run:

sudo apt-get install npm ruby-sass

or if you have bundler you can install ruby-sass simply via bundle install

Execute these commands on your server as a normal user to prepare the dependencies:

git clone https://github.com/tcatm/meshviewer.git
cd meshviewer
npm install
npm install grunt-cli

Building

Just run the following command from the meshviewer directory:

node_modules/.bin/grunt

This will generate build/ containing all required files.

Configure

Copy config.json.example to build/config.json and change it to match your community.

dataPath (string)

dataPath must point to a directory containing nodes.json and graph.json (both are generated by ffmap-backend). Don't forget the trailing slash! Data may be served from a different domain with CORS enabled. Also, GZip will greatly reduce bandwidth consumption.

siteName (string)

Change this to match your communities' name. It will be used in various places.

mapSigmaScale (float)

This affects the initial scale of the map. Greater values will show a larger area. Values like 1.0 and 0.5 might be good choices.

showContact (bool)

Setting this to false will hide contact information for nodes.

maxAge (integer)

Nodes being online for less than maxAge days are considered "new". Likewise, nodes being offline for less than than maxAge days are considered "lost".

mapLayers (List)

A list of objects describing map layers. Each object has at least name property and optionally url and config properties. If no url is supplied name is assumed to name a Leaflet-provider.

nodeInfos (array, optional)

This option allows to show client statistics depending on following case-sensitive parameters:

• name caption of statistics segment in infobox
• href absolute or relative URL to statistics image
• thumbnail absolute or relative URL to thumbnail image, can be the same like href
• caption is shown, if thumbnail is not present (no thumbnail in infobox)

To insert current node-id in either href, thumbnail or caption you can use the case-sensitive template string {NODE_ID}.

Examples for nodeInfos:

"nodeInfos": [
  { "name": "Clientstatistik",
    "href": "nodes/{NODE_ID}.png",
    "thumbnail": "nodes/{NODE_ID}.png",
    "caption": "Knoten {NODE_ID}"
  },
  { "name": "Uptime",
    "href": "nodes_uptime/{NODE_ID}.png",
    "thumbnail": "nodes_uptime/{NODE_ID}.png",
    "caption": "Knoten {NODE_ID}"
  }
]

In order to have statistics images available, you have to run the backend with parameter --with-rrd or generate them in other ways.

globalInfos (array, optional)

This option allows to show global statistics on statistics page depending on following case-sensitive parameters:

• name caption of statistics segment in infobox
• href absolute or relative URL to statistics image
• thumbnail absolute or relative URL to thumbnail image, can be the same like href
• caption is shown, if thumbnail is not present (no thumbnail in infobox)

In contrast to nodeInfos there is no template substitution in href, thumbnail or caption.

Examples for globalInfos:

"globalInfos": [
  { "name": "Wochenstatistik",
    "href": "nodes/globalGraph.png",
    "thumbnail": "nodes/globalGraph.png",
    "caption": "Bild mit Wochenstatistik"
  },
  { "name": "Jahresstatistik",
    "href": "nodes/globalGraph52.png",
    "thumbnail": "nodes/globalGraph52.png",
    "caption": "Bild mit Jahresstatistik"
  }
]

In order to have global statistics available, you have to run the backend with parameter --with-rrd (this only creates globalGraph.png) or generate them in other ways.

Colors and Radius for Nodes

In lib/map.js you can change the colors and radius for nodes in different states:

• iconNew: Nodes that are online for less than maxAge days (default: green, radius: 6)
• iconOnline: online for more than maxAge days (default blue, radius: 6)
• iconAlert: nodes offline less than 8 Hours (default: blinking red, radius: 5)
• iconLost: nodes being offline for less than than maxAge days (default: grey, radius: 5)
• iconOffline: offline for more than maxAge days up to the maximum prune time of the backend (default: grey, radius: 3)

siteNames (array, optional)

In this array name definitions for site statistics and node info can be saved. This requires one object for each site code. This object must contain:

• site the site code
• name the defined written name for this site code

If neither siteNames nor showSites are set, site statistics and node info won't be displayed

Example for siteNames:

"siteNames": [
  { "site": "ffhl", "name": "Lübeck" },
  { "site": "ffgt", "name": "Gothamcity" },
  { "site": "ffal", "name": "Atlantis" }
]

Building

Just run the following command from the meshviewer directory:

node_modules/.bin/grunt

This will generate build/ containing all required files.

Deploy

To deploy the meshviewer on your server, just rsync build/ into your servers document-home, for example:

sudo rsync -av --delete build/ /var/www/meshviewer/
