# termap - Terminal Map Viewer
Discover the world in your console! termap allows you to render and navigate
VectorTile based maps in your console.
Discover the world in your console!
* No native dependencies, 100% Coffee-/JavaScript
* Use your mouse or keyboard to navigate the map
* Use tile servers or local MBTiles and VectorTiles
* Use your mouse or keyboard to navigate
* Watch the globe or zoom down to house numbers
* Use tile servers, local MBTiles or a single VectorTile
## How to get it?
`npm install -g termap`
* Make sure to have [node.js](https://nodejs.org/) installed
* Install `termap` with
`npm install -g termap`
## How to use it?
* Start `termap` with
` termap`
## Behind the scenes
### Libraries
* [`pbf`](https://github.com/mapbox/pbf) for Protobuf decoding
* [`vector-tile`](https://github.com/mapbox/vector-tile-js) for [VectorTile](https://github.com/mapbox/vector-tile-spec/tree/master/2.1) parsing
* [`drawille-canvas-blessed-contrib`](https://github.com/yaronn/drawille-canvas-blessed-contrib/) for braille rendering
* [`term-mouse`](https://github.com/CoderPuppy/term-mouse) for mouse handling
* [`keypress`](https://github.com/TooTallNate/keypress) for input handling
* [`node-drawille`](https://github.com/madbence/node-drawille/) for braille rendering (to be replaced)
* [`node-mbtiles`](https://github.com/mapbox/node-mbtiles) for MBTiles parsing
* [`pbf`](https://github.com/mapbox/pbf) for Protobuf decoding
* [`vector-tile-js`](https://github.com/mapbox/vector-tile-js) for [VectorTile](https://github.com/mapbox/vector-tile-spec/tree/master/2.1) parsing
* [`sphericalmercator`](https://github.com/mapbox/node-sphericalmercator) for EPSG:3857 <> WGS84 conversions
## Wishlist
* node-gyp binding to [libdrawille](https://github.com/Huulivoide/libdrawille) for speed refactor possibilities + filled polygons
* node port of [libdrawille](https://github.com/Huulivoide/libdrawille) - well optimized library, supporting filled polygons
### TODOs
* [ ] cli linking
* [ ] mapping of view to tiles to show
* [ ] label drawing
* [x] support for point labels
* [ ] dynamic decluttering of labels
* [ ] lat/lng-center + zoom based viewport
* [ ] TileSource class (abstracting URL, mbtiles, single vector tile source)
* [ ] tile request system
* [ ] from local mbtiles
* [ ] from remote url
* [ ] label drawing
* [ ] lat/lng-center + zoom based viewport
* [ ] TileSource class (abstracting URL, mbtiles, single vector tile source)
* [ ] permanent caching of received files
* [ ] zoom while keeping center
* [ ] API
* [ ] setCenter
* [ ] setZoom
* [x] accurate mouse drag&drop
* [x] handle console resize
* [ ] turn this into a [`blessed-contrib`](https://github.com/yaronn/blessed-contrib) widget
