This way the health checks will only check for Redis and Mapnik initialization. An empty tile without layers or datasources is generated. |

Windshaft-CartoDB
[
]
(http://travis-ci.org/CartoDB/Windshaft-cartodb)
This is the CartoDB map 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_idas 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
infowindowendpoint for windshaft (DEPRECATED) - provides a
map_metadataendpoint for windshaft (DEPRECATED) - provides signed template maps API (http://github.com/CartoDB/Windshaft-cartodb/wiki/Template-maps)
Requirements
[core]
- node-0.8.x+
- PostgreSQL-8.3+
- PostGIS-1.5.0+
- Redis 2.4.0+ (http://www.redis.io)
- Mapnik 2.0 or 2.1
[for cache control]
- CartoDB-SQL-API 1.0.0+
- CartoDB 0.9.5+ (for
CDB_QueryTables) - Varnish (http://www.varnish-cache.org)
[for running the testsuite]
- Imagemagick (http://www.imagemagick.org)
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
Build/install
To fetch and build all node-based dependencies, run:
git clone
npm install
Note that the npm install step will populate the node_modules/
directory with modules, some of which being compiled on demand. If you
happen to have startup errors you may need to force rebuilding those
modules. At any time just wipe out the node_modules/ directory and run
npm install again.
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
URLs
TILES
[GET] subdomain.cartodb.com/tiles/:table_name/:z/:x/:y.[png|png8|grid.json]
Args:
- sql - plain SQL arguments
- interactivity - specify the column to use in UTFGrid
- cache_buster - Specify an identifier for the internal tile cache. Requesting tiles with the same cache_buster value may result in being served a cached version of the tile (even when requesting a tile for the first time, as tiles can be prepared in advance)
- cache_policy - Set to "persist" to have the server send an Cache-Control header requesting caching devices to keep the response cached as much as possible. This is best used with a timestamp value in cache_buster for manual control of updates.
- geom_type - override the cartodb default
- style - override the default map style with Carto
STYLE
[GET/POST] subdomain.cartodb.com/tiles/:table_name/style
Args:
- style - the style in CartoCSS you want to set
- style_version - the version of the style for POST
- style_convert - request conversion to target version (both POST and GET)
INFOWINDOW
[GET] subdomain.cartodb.com/tiles/:table_name/infowindow
Args:
- infowindow - returns contents of infowindow from CartoDB.
MAP METADATA
[GET] subdomain.cartodb.com/tiles/:table_name/map_metadata
Args:
- infowindow - returns contents of infowindow from CartoDB.
All GET requests are wrappable with JSONP using callback argument, including the UTFGrid map tile call.
