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
|

## 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
|
|
<link rel="stylesheet" class="css-mode mode-name" media="not" href="mode-name.css">
|
|
```
|
|
|
|
or
|
|
|
|
```html
|
|
<style class="css-mode mode-name" media="not">
|
|
<inline src="mode-name.css" />
|
|
</style>
|
|
```
|
|
|
|
#### 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)._
