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.
