Mapbox vector tileserver

Simple example demonstrating how to use node-mapnik to generate Mapbox format vector tiles on the fly from a PostGIS data source, using TypeScript.

Pre-requisites

• node-mapnik dependencies
• Postgres database with PostGIS installed, pre-populated with geospatial data

Setup

Create a file .env and add the following:

DB_HOST=... // e.g. <mypostgreshost.com>
DB_PORT=...
DB_NAME=...
DB_USER=...
DB_PASSWORD=...

(or manually set these as environment variables)

Modify EXAMPLE_TABLE_QUERY in constants.ts to pull in the data that you require. The results set must contain a column of type geometry.

Run

1. npm install
2. npm start
