# Windshaft-CartoDB [](https://travis-ci.org/CartoDB/Windshaft-cartodb)
|
|
|
|
The [`CARTO Maps API`](http://docs.cartodb.com/cartodb-platform/maps-api.html) tiler. It extends [`Windshaft`](https://github.com/CartoDB/Windshaft) and exposes a web service with extra functionality:
|
|
|
|
* Instantiate [`Anonymous Maps`](https://github.com/CartoDB/Windshaft-cartodb/blob/master/docs/guides/03-anonymous-maps.md) through CARTO's map configuration ([`MapConfig`](https://github.com/CartoDB/Windshaft/blob/master/doc/MapConfig-specification.md)).
|
|
* Create [`Named Maps`](https://github.com/CartoDB/Windshaft-cartodb/blob/master/docs/guides/04-named-maps.md) based on customizable templates.
|
|
* Get map previews through [`Static Maps`](https://github.com/CartoDB/Windshaft-cartodb/blob/master/docs/guides/05-static-maps-API.md) API.
|
|
* Render maps with a large amount of data faster using [`Tile Aggregation`](https://github.com/CartoDB/Windshaft-cartodb/blob/master/docs/guides/06-tile-aggregation.md).
|
|
* Build advanced maps with enriched data through [`Analyses Extension`](https://github.com/CartoDB/Windshaft-cartodb/blob/master/docs/guides/09-MapConfig-analyses-extension.md).
|
|
* Fetch tabular data from analysis nodes with [`Dataviews`](https://github.com/CartoDB/Windshaft-cartodb/blob/master/docs/guides/10-MapConfig-dataviews-extension.md)
|
|
|
|
## Build
|
|
|
|
Requirements:
|
|
|
|
* [`Node 10.x (npm 6.x)`](https://nodejs.org/dist/latest-v10.x/)
|
|
* [`PostgreSQL >= 10.0`](https://www.postgresql.org/download/)
|
|

|
|
* [`CARTO Postgres Extension >= 0.24.1`](https://github.com/CartoDB/cartodb-postgresql)
|
|
* [`Redis >= 4`](https://redis.io/download)
|
|
* `libcairo2-dev`, `libpango1.0-dev`, `libjpeg8-dev` and `libgif-dev` for server side canvas support
|
|
* `C++11` to build internal dependencies. When there's no pre-built binaries for your OS/architecture distribution.
|
|
|
|
Optional:
|
|
|
|
* [`Varnish`](http://www.varnish-cache.org)
|
|
* [`Statsd`](https://github.com/statsd/statsd)
|

### PostGIS setup
|
|
|
|
A `template_postgis` database is expected. One can be set up with
|
|
|
|
```shell
|
|
$ createdb --owner postgres --template template0 template_postgis
|
|
$ psql -d template_postgis -c 'CREATE EXTENSION postgis;'
|
|
```
|
|
|
|
### Install
|
|
|
|
To fetch and build all node-based dependencies, run:
|
|
|
|
```shell
|
|
$ npm install
|
|
```
|
|
|
|
### 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.
|
|
|
|
```shell
|
|
$ node app.js <env>
|
|
```
|
|
|
|
Where `<env>` is the name of a configuration file under `./config/environments/`.
|
|
|
|
### Test
|
|
|
|
```shell
|
|
$ npm test
|
|
```
|
|
|
|
### Coverage
|
|
|
|
```shell
|
|
$ npm run cover
|
|
```
|
|
|
|
Open `./coverage/lcov-report/index.html`.
|
|
|
|
### Docker support
|
|
|
|
We provide docker images just for testing and continuous integration purposes:
|
|
|
|
* [`nodejs-xenial-pg1121`](https://hub.docker.com/r/carto/nodejs-xenial-pg1121/tags)
|
|
* [`nodejs-xenial-pg101`](https://hub.docker.com/r/carto/nodejs-xenial-pg101/tags)
|
|
|
|
You can find instructions to install Docker, download, and update images [here](https://github.com/CartoDB/Windshaft-cartodb/blob/master/docker/reference.md).
|
|
|
|
### Useful `npm` scripts
|
|
|
|
Run test in a docker image with a specific Node.js version:
|
|
|
|
```shell
|
|
$ DOCKER_IMAGE=<docker-image-tag> NODE_VERSION=<nodejs-version> npm run test:docker
|
|
```
|
|
|
|
Where:
|
|
|
|
* `<docker-image-tag>`: the tag of required docker image, e.g. `carto/nodejs-xenial-pg1121:latest`
|
|
* `<nodejs-version>`: the Node.js version, e.g. `10.15.1`
|
|
|
|
In case you need to debug:
|
|
|
|
```shell
|
|
$ DOCKER_IMAGE=<docker-image-tag> npm run docker:bash
|
|
```
|
|
|
|

## 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 `npm link`. You can read more about it at `npm-link`: [symlink a package folder](https://docs.npmjs.com/cli/link.html).
|
|
|
|
```shell
|
|
$ cd /path/to/Windshaft
|
|
$ npm install
|
|
$ npm link
|
|
$ cd /path/to/Windshaft-cartodb
|
|
$ npm link windshaft
|
|
```
|
|
|
|
