meshviewer/README.md

Main differences to https://github.com/ffnord/meshviewer

Some features are maybe merged

• Add modes - For example add a night layer and style
• Updates selected node or list (incl. image stats cache-breaker) - not only overview tables
• Node filter is implemented
• Zoom level if you click a node (nodeZoom) - Zoom level 22 available, but it is to close for a click
• Formatted Code
• Translation support - https://crowdin.com/project/meshviewer
• Grunt inline for some css and js - less requests
• Icon font with only needed icons
• Upgrade to grunt v1.x (Tested with Node.js 4 LTS,6 LTS,7 Linux,OSX,W**)
  • Inline some css and js
• Remove bower in favour of npm/yarn
  • Load only german locale from 101 languages from moment.js
• Right click open layermenu
• Remove ruby dependency
• FixedCenter is required
• Rewrite Scss, SASS lint and variables for easy customization/adjustments
• Improved cross browser/device support THX@BrowserStack
• Leaflet with patch to avoid IE/Edge crashes
• Add yarn package manager in favor of npm (npm still works)
• Configurable reverse geocoding server
• A lot more in commit history

TODO new uptodate images

Dependencies

• yarn
• grunt-cli

Installing dependencies

npm is still possible, but yarn is much faster https://yarnpkg.com/

Install yarn package-manager:

Chosse your OS and install yarn https://yarnpkg.com/en/docs/install

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

git clone https://github.com/ffrgb/meshviewer.git
cd meshviewer
yarn
# Only needed when no global grunt exists
yarn global add grunt-cli

Building

Just run the following command from the meshviewer directory:

grunt

This will generate build/ containing all required files.

Development

Use grunt serve for development.

Support/Help

• IRC: irc.hackint.org #freifunkRGB
• Feel free to open an issue for a problem or a idea.

Configure

Change config.jsonto match your community.

Customize style

Start your development and edit files in scss/custom/. Additional information in comments.

dataPath (string/array)

dataPath can be either a string containing the address of a Nodes.json v2 compatible backend (e.g. ffmap backend) or an array containing multiple addresses. Don't forget the trailing slash! Also, proxying the data through a webserver will allow GZip and thus will greatly reduce bandwidth consumption. It may help with firewall problems too.

siteName (string)

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

maxAge (integer)

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

maxAgeAlert (integer)

Nodes being offline for more than than maxAge days are considered "lost". Lost will be splitted in alert and lost.

nodeZoom (integer)

Max level to be applied by clicking a node or open a node. With value 18 near by buildings and streets should be visible. Interesting if one of configured map provider has zoom-level under 18.

nodeInfobox

contact (bool)

Setting this to false will hide contact information for nodes.

hardwareUsage (bool)

Setting this to false will hide bars of memory usage and load avg for nodes.

mapLayers (List)

A list of objects describing map layers. Each object has at least name, url and config properties. Example layers and configuration (map against config.json).

Additional arguments

mode (string)

Allows to load a additional style for a night mode or similar use case. Possible are inline style or link. Inline avoids re-rendering and maybe issues with label-layer update. Important are class "css-mode mode-name" and media "not".

Default is night.css inline in index.html

 <link rel="stylesheet" class="css-mode mode-name" media="not" href="mode-name.css">

or

<style class="css-mode mode-name" media="not">
   <inline src="mode-name.css" />
</style>

start (integer)

Start a time range to put this mapLayer on first position.

end (integer)

End a time range for first map. Stops sort this mapLayer.

fixedCenter (array, optional)

This option allows to fix the map at one specific coordinate depending on following case-sensitive parameters:

• lat latitude of the center point
• lng longitude of the center point
• radius visible radius around the center in km

Examples for fixedCenter:

"fixedCenter": {
  "lat": 50.80,
  "lng": 12.07,
  "radius": 30
}

nodeInfos (array, optional)

This option allows to show node 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}, {NODE_NAME}, {LOCALE} and {TIME} as cache-breaker.

Examples for nodeInfos:

"nodeInfos": [

  { "name": "Clientstatistik",
    "href": "stats/dashboard/db/node-byid?var-nodeid={NODE_ID}",
    "thumbnail": "stats/render/dashboard-solo/db/node-byid?panelId=1&fullscreen&theme=light&width=600&height=300&var-nodeid={NODE_ID}&var-host={NODE_NAME}&_t={TIME}",
    "caption": "Knoten {NODE_ID}"
  },
  { "name": "Uptime",
    "href": "stats/dashboard/db/node-byid?var-nodeid={NODE_ID}",
    "thumbnail": "stats/render/dashboard-solo/db/node-byid?panelId=2&fullscreen&theme=light&width=600&height=300&var-nodeid={NODE_ID}&_t={TIME}",
    "caption": "Knoten {NODE_ID}"
  }
]

In order to have statistics images available, you have to set up an instance of each Prometheus and Grafana.

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 using Grafana server rendering:

"globalInfos": [
  { "name": "Wochenstatistik",
    "href": "stats/render/render/dashboard-solo/db/global?panelId=1&fullscreen&theme=light&width=600&height=300",
    "thumbnail": "nodes/globalGraph.png",
    "caption": "Bild mit Wochenstatistik"
  }
]

linkInfos (array, optional)

This option allows to show link statistics depending on the 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 the source or target node-id in either href, thumbnail or caption you can use the case-sensitive template strings {SOURCE_ID}, {TARGET_ID}, {SOURCE_NAME}, {TARGET_NAME}, {LOCALE} and {TIME} as cache-breaker.

"linkInfos": [
  { "href": "stats/dashboard/db/links?var-source={SOURCE_ID}&var-target={TARGET_ID}",
    "thumbnail": "stats/render/dashboard-solo/db/links?panelId=1&fullscreen&theme=light&width=800&height=600&var-source={SOURCE_ID}&var-target={TARGET_ID}&_t={TIME}"
  }
]

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": "ffeh", "name": "Entenhausen" ),
  { "site": "ffgt", "name": "Gothamcity" },
  { "site": "ffal", "name": "Atlantis" }
]

supportedLocale (array)

Add supported locale (with matching language file in locales/*.json) and it will be matched against the browser language setting. Fallback is the first language in the array.

Example for supportedLocale:

"supportedLocale": [
  "en",
  "de"
]

cacheBreaker (string)

Will be replaced in every build to avoid missing or outdated language strings, because language.json isn't up to date.

Fixed value (y0z).
