TileMantle is a tile invalidation/warming server. POST geometries to it and it'll incremently re-render the the affected tiles. It comes with a nice dashboard that lets you watch the progress in realtime.
In your project root, create a "tilemantle.json":
{
"port": 8080,
"store": {
"adapter": "sqlite",
"file": "./tilemantle.lite"
},
// what should the filesize of posted geojson be capped at?
"upload_limit": "5mb",
// these settings are inherited by each item in "requests" for each preset
"preset_defaults": {
"retries": 5,
"retry_delay": 1000
},
// this is the important part. presets are
"presets": {
