A web-app to visualize nodes and links on a map for Freifunk open mesh network.
#### Main differences to https://github.com/ffnord/meshviewer
_Some similar features might have been implemented/merged_
- Map layer modes (Allow to set a default layer based on time combined with a stylesheet)
- Automatic updates for selected node or list (incl. image stats cache-breaker)
- Node filter
- Zoom level for clicking on a node (`nodeZoom`) is definable independently from the maximum zoom level 22
- Formatted Code
- Translation support - https://crowdin.com/project/meshviewer - Contact us for new languages
- Currently available: en, de, fr & ru
- Grunt inline for some css and js - less requests
- Icon font with needed icons only
- Grunt upgraded to v1.x (Tested with Node.js 4/6 LTS, 7 on Linux, 7 OSX & W**)
- css and some js moved inline
- Yarn/npm in favour of bower
- Load only moment.js without languages (Languages are included in translations)
- unneeded components removed (es6-shim, tablesort, numeraljs, leaflet-providers, jshashes)
- RBush v2 - performance boost in last versions (positions, labels and clients on the map)
- Ruby dependency removed
- FixedCenter is required
- Sass-lint, scss and variables rewritten for easy customizations/adjustments
- Cross browser/device support improved (THX@BrowserStack)
- Leaflet fork with a patch to avoid IE/Edge crashes
- Yarn package manager in favour of npm (npm still works)
- Configurable reverse geocoding server
- [A lot more in the commit history](https://github.com/ffrgb/meshviewer/commits/develop)

## Dependencies
- yarn (npm fallback)
- grunt-cli
### Installing dependencies
_npm is still possible to use, but yarn is much faster https://yarnpkg.com/_
Install yarn package-manager:
Choose 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:
```bash
git clone https://github.com/ffrgb/meshviewer.git
cd meshviewer
yarn
# Only needed if no global grunt is installed
yarn global add grunt-cli
```
## Building
Just run the following command from the meshviewer directory:
```bash
grunt
```
This will generate the folder `build/` that will contain all required files.
## Development
Use `grunt serve` for development.

## Customize style
Start your development and edit files in `scss/custom/`. Additional information in file comments.
## Configure
Change `config.json`to match your community.
### 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 opening a node. Value `18` is a good default, so nearby buildings and streets should be visible.
### labelZoom (integer)
Min. level for node labels shown on the map. Labels aren't shown in first zoom levels and need performance.
### clientZoom (integer)
Min. level to set starting layer for client dots on map.
### nodeInfobox
#### contact (bool, optional)
Setting this to `false` will hide contact information for nodes.
#### hardwareUsage (bool, optional)
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](http://leaflet-extras.github.io/leaflet-providers/preview/) (map against config.json).
#### mode (string, optional)
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_
```html
```
or
```html
```
#### start (integer, optional)
Start a time range to put this mapLayer on first position.
#### end (integer, optional)
End a time range for first map. Stops sort this mapLayer.
### fixedCenter (array[array, array])
Choose a rectangle that must be displayed on the map. Set 2 Locations and everything between will displayed.
Examples for `fixedCenter`:
```json
// Set a visible frame
"fixedCenter": [
[
49.3522,
11.7752
],
[
48.7480,
12.8917
]
],
```
### nodeInfos (array, optional)
This option allows to show node statistics depending on following case-sensitive parameters:
- `name` header of statistics segment in infobox
- `href` absolute or relative URL to statistics image
- `image` `(required)` absolute or relative URL to image,
can be the same like `href`
- `title` for the image
To insert current variables in either `href`, `image` or `title`
you can use the case-sensitive template string `{NODE_ID}`, `{NODE_NAME}`, `{LOCALE}` and `{TIME}` as cache-breaker.
Examples for `nodeInfos`:
```json
"nodeInfos": [
{
"name": "Clientstatistik",
"href": "stats/dashboard/db/node-byid?var-nodeid={NODE_ID}",
"image": "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}",
"title": "Knoten {NODE_ID}"
},
{
"name": "Uptime",
"href": "stats/dashboard/db/node-byid?var-nodeid={NODE_ID}",
"image": "stats/render/dashboard-solo/db/node-byid?panelId=2&fullscreen&theme=light&width=600&height=300&var-nodeid={NODE_ID}&_t={TIME}",
"title": "Knoten {NODE_ID}"
}
]
```
In order to have statistics images available, you have to set up an instance of each [Prometheus](http://prometheus.io/) and [Grafana](http://grafana.org/).
### globalInfos (array, optional)
This option allows to show global statistics on statistics page depending on following case-sensitive parameters:
- `name` header of statistics segment in infobox
- `href` absolute or relative URL to statistics image
- `image` `(required)` absolute or relative URL to image,
can be the same like `href`
- `title` for the image
In contrast to `nodeInfos` there is no template substitution in `href`, `image` or `title`.
Examples for `globalInfos` using Grafana server rendering:
```json
"globalInfos": [
{
"name": "Wochenstatistik",
"href": "stats/render/render/dashboard-solo/db/global?panelId=1&fullscreen&theme=light&width=600&height=300",
"image": "nodes/globalGraph.png",
"title": "Bild mit Wochenstatistik"
}
]
```
### linkInfos (array, optional)
This option allows to show link statistics depending on the following case-sensitive parameters:
- `name` header of statistics segment in infobox
- `href` absolute or relative URL to statistics image
- `image` `(required)` absolute or relative URL to image,
can be the same like `href`
- `title` for the image
To insert the source or target variable in either `href`, `image` or `title`
you can use the case-sensitive template strings `{SOURCE_ID}`, `{TARGET_ID}`, `{SOURCE_NAME}`, `{TARGET_NAME}`, `{LOCALE}` and `{TIME}` as cache-breaker.
```json
"linkInfos": [
{
"name": "Linkstatistik",
"href": "stats/dashboard/db/links?var-source={SOURCE_ID}&var-target={TARGET_ID}",
"image": "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}",
"title": "Bild mit Linkstatistik"
}
]
```
### 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`:
```json
"siteNames": [
{
"site": "ffrgb",
"name": "Regensburg"
},
{
"site": "ffrgb-dummy",
"name": "Regensburg Test"
}
],
```
### 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`:
```json
"supportedLocale": [
"en",
"de",
"fr"
]
```
### 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)._
