ddj.map.js

ddj.map makes it easier working with data on maps

This is one of the very first version of this npm package. Adding more functionality and removing the bugs occupy much time. So the documentation suffers a lot.

Write your own map

1. Create a HTML file template

Create a new and empty HTML file. Copy the code below and get a blueprint of a simple website. The lines beginning with <!-- are placeholder for later use.

<!DOCTYPE HTML>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=7; IE=EmulateIE9; IE=10" />

    <!-- put in your app icon here -->
    <!-- put in the lib here -->
    <!-- put in the data here -->
    <!-- put in the map here -->
    <!-- put in the map pins here -->

    <!-- placeholder for Google, Facebook and Twitter -->
</head>
<body>
</body>
</html>

Language setting, e.g. lang="de" for map attribution.

<html lang="de" xmlns="http://www.w3.org/1999/xhtml">

2. use the lib and choose a theme

Replace ...

<!-- put in the lib here -->
<link rel="stylesheet" href="https://unpkg.com/ddj.map@1.0.21/dist/ddj.map.css" />
<script src="https://unpkg.com/ddj.map@1.0.21/dist/ddj.map.js"></script>

3. set a data source

Replace ...

<!-- put in the data here -->
<meta name="ddj:data" content="path/to/data.csv">
<meta name="ddj:dataType" content="csv">
<meta name="ddj:dataUniqueIdentifier" content="id">

dataType is one of

json (default)
geojson
csv
wfs (in planning)

If you see CORS problems use

<meta name="ddj:dataUseCorsProxy" content="cors-anywhere.herokuapp.com">

Additional ...

<meta name="ddj:dataIgnoreSecondLine" content="false">
<meta name="ddj:dataIgnoreLastLine" content="false">
<meta name="ddj:dataNoCache" content="true">
<meta name="ddj:dataDelimiter" content=",">
<meta name="ddj:latitudeColumn" content="lat">
<meta name="ddj:longitudeColumn" content="lng">

Info ... CORS problems should be solved by 3rd party proxy
