Windshaft-CartoDB

This is the CARTO Maps API tiler. It extends Windshaft and exposes a complete web service with extra functionality:

Instantiate Anonymous Maps through CARTO's map configuration (MapConfig).
Create Named Maps based on customizables templates.
Get map previews through Static Maps API.
Render maps with large amount of data faster using Tile Aggregation.
Build advanced maps with enriched data through Analyses Extension.
Fetch tabular data from analysis nodes with Dataviews

Install

Requirements

Node 10.x
npm 6.x
PostgreSQL >= 10.0
PostGIS >= 2.4
CARTO Postgres Extension >= 0.24.1
Redis >= 4
libcairo2-dev, libpango1.0-dev, libjpeg8-dev and libgif-dev for server side canvas support
C++11 (to build internal dependencies if needed)

Optional

Varnish

PostGIS setup

A template_postgis database is expected. One can be set up with

$ createdb --owner postgres --template template0 template_postgis
$ psql -d template_postgis -c 'CREATE EXTENSION postgis;'

Build

To fetch and build all node-based dependencies, run:

$ npm ci

Run

Create the ./config/environments/<env>.js file (there are .example files to start from). Look at ./lib/cartodb/server-options.js for more on config.

$ node app.js <env>

Where <env> is the name of a configuration file under ./config/environments/.

Documentation

The docs directory contains different documentation resources, from higher level to more detailed ones: the Maps API document defines the endpoints and their expected parameters and outputs.
