Windshaft-CartoDB

This is the CartoDB Maps API tiler. It extends Windshaft with some extra functionality and custom filters for authentication.

• reads dbname from subdomain and cartodb redis for pretty tile urls
• configures windshaft to publish cartodb_id as the interactivity layer
• gets the default geometry type from the cartodb redis store
• allows tiles to be styled individually
• provides a link to varnish high speed cache
• provides a template maps API

Install

See INSTALL.md for detailed installation instructions.

Configure

Create the config/environments/.js files (there are .example files to start from). You can optionally use the ./configure script for this, see ./configure --help to see available options.

Look at lib/cartodb/server_options.js for more on config

Upgrading

Checkout your commit/branch. If you need to reinstall dependencies (you can check NEWS) do the following:

• Node.js >= 10.14.2:

$ rm -rf node_modules
$ npm install

• Node.js 6.9.2:

$ rm -rf node_modules
$ yarn

Run

node app.js <env>

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

Note that caches are kept in redis. If you're not seeing what you expect there may be out-of-sync records in there. Take a look: http://redis.io/commands

Documentation

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

Examples

CartoDB's Map Gallery showcases several examples of visualisations built on top of this.

Developing with a custom windshaft version

If you plan or want to use a custom / not released yet version of windshaft (or any other dependency) the best option is to use yarn link. You can read more about it at yarn-link: Symlink a package folder.

Quick start:

• Node.js >= 10.14.2:

~/windshaft-directory $ npm ci
~/windshaft-directory $ npm link
~/windshaft-cartodb-directory $ npm link windshaft

• Node.js 6.9.2:

~/windshaft-directory $ yarn
~/windshaft-directory $ yarn link
~/windshaft-cartodb-directory $ yarn link windshaft
