Yelapa

Yelapa is a parser for Simple Location Markdown Language (SloML). The library can be used to turn human-readable list of addresses, point of interests or countries into Geojson data.

Note: Mapbox API key is required

How it works

SloML (pronounced slow-mel) has the following convention

This is a short description  
--
Location one
--
location two
--
some address

• Separate each entry by two dashes (--)
• Yelapa will perform geocoding look up (using Mapbox) to find GPS coordinates for each entry

Real example:

My travels in 2018
--
Berlin
--
Bondi beach
--
Valencia spain

Usage

# npm install @mappandas/yalepa

Yelapa.parse(raw_input, onData(ast, featureCollection) , onError(error));

import Yelapa from "@mappandas/yelapa";

...

    const geocoder = new Yelapa(
      "mapbox API key"
    );
  
  const input =¨"My travels in 2018\n--\nberlin\--\ntokyo";
   geocoder.parse(
      input,
      (ast: any, fc: FeatureCollection) => {
         // ast: syntax tree data
         // fc: featurecollection
      },
      (e:any) => {
       // handle error
      }
    );
