tilewarm

A command-line tool to warm up your tile server cache. Give it a URL template, coordinates, and list of zoom levels and it will systematically request all tile images in the given area.

npm install -g @alvarcarto/tilewarm

Docker example:

docker build -t tilewarm .
docker run tilewarm http://yourtileserver.com/{z}/{x}/{y}.png --input geojson/world.geojson --zoom 1-5

Examples

1-5 levels, 20km radius from the center of Barcelona

tilewarm http://yourtileserver.com/{z}/{x}/{y}.png --point 41.38,2.16 --buffer 20km --zoom 1-5

1-5 levels of the world (~1.3k requests)

tilewarm http://yourtileserver.com/{z}/{x}/{y}.png --input geojson/world.geojson --zoom 1-5

1,3,5 levels of the world (~1k requests)

tilewarm http://yourtileserver.com/{z}/{x}/{y}.png --input geojson/world.geojson --zoom 1,3,5

6-8 levels for all cities in the world (~4k requests)

tilewarm http://yourtileserver.com/{z}/{x}/{y}.png --input geojson/all-cities.geojson --zoom 6-8

6-14 levels for all cities in the world (~1.2M requests)

tilewarm http://yourtileserver.com/{z}/{x}/{y}.png --input geojson/all-cities.geojson --zoom 6-14

15 level for all cities in the world (~3M requests)

tilewarm http://yourtileserver.com/{z}/{x}/{y}.png --input geojson/all-cities.geojson --zoom 15

Usage: tilewarm <url> [options]

<url>   Tile URL template

  --retry-base-timeout  Base timeout defines how many ms to wait before retrying
                        a request. The final wait time is calculated with

                        mi,km                          [string] [default: "0km"]
  -z, --zoom            Zoom levels (comma separated or range)
                                                       [string] [default: "3-9"]
  -l, --list            Don't perform any requests, just list all tile URLs
                                                      [boolean] [default: false]
  -i, --input           GeoJSON input file              [string] [default: null]
  -c, --concurrency     How many concurrent requests to execute     [default: 5]
  -m, --method          Which HTTP method to use in requests

Warming cache for all cities in the world

Form a geojson for all cities in the world.

node tools/cities-to-geojson.js tools/cities.csv > cities.geojson

# Put geojson to clipboard, works on Mac
cat cities.geojson | pbcopy

You can debug the geojson by pasting it into http://geojson.io/. The file can be compressed even more with https://www.npmjs.com/package/geojson-precision.

Then run:

tilewarm http://yourtileserver.com/{z}/{x}/{y}.png --input cities.geojson

Zoom levels visually

Each zoom level 3-19.
