# PMTiles on Lambda # Installation
Generates a Lambda function for deploying PMTiles on Lambda behind Lambda Function URLs or API Gateway. (CloudFront is recommended as a cache in front.) See installation and configuration instructions at [Protomaps Docs: Deploy on AWS](https://protomaps.com/docs/cdn/aws)
The `Content-Type` header of responses will be `application/vnd.mapbox-vector-tile` : this is one of the [CloudFront compressible types](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/ServingCompressedFiles.html#compressed-content-cloudfront-file-types). ## Development
## How To Use
Self-contained Lambda ZIP:
[protomaps.github.io/PMTiles/lambda_function.zip](https://protomaps.github.io/PMTiles/lambda_function.zip)
(On Safari, right click -> Download Linked File... will keep the ZIP intact)

Configure these Lambda environment variables: ## Test Events
* `BUCKET`: the S3 bucket name. Simulate tile requests in the Lambda development console with these JSON events:
* `PMTILES_PATH`: optional, define how a tileset name is translated into an S3 key. Default `{name}.pmtiles`
* Example path setting for objects in a directory: `my_folder/{name}/file.pmtiles`
* `TILE_PATH`: optional, define the URL route of the tiles API. Default `/{name}/{z}/{x}/{y}.pbf`
* `CORS`: optional, set the value of the `Access-Control-Allow-Origin` response header. Examples: `https://example.com`, `*`. Only supports one origin, so useful for development or staging environments only. For production use you should use CloudFront CORS configuration.

### Lambda@Edge
Lambda@Edge's multi-region features have little benefit when fetching data from S3 in a single region, and Lambda@Edge [doesn't support](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/edge-functions-restrictions.html) environment variables or responses over 1 MB. For globally distributed caching, use CloudFront in combination with Lambda Function URLs.
### API Gateway
* your Lambda Proxy Integration route will need to specify a greedy capturing parameter called `proxy` e.g. `/{proxy+}` (the default).
* API Gateway responses will always be GZIP-encoded, to work around binary content detection problems.

# PMTiles on Cloudflare Workers # Protomaps on Cloudflare
Use [rclone](https://rclone.org/downloads/) to upload your PMTiles archives to an R2 bucket. The Web UI is limited to 300 MB. See installation and configuration instructions at [Protomaps Docs: Deploy on Cloudflare](https://protomaps.com/docs/cdn/cloudflare)
# Getting started ## Development
* First run `npm install` in the root `PMTiles/js` directory, then `npm install` in `PMTiles/serverless/cloudflare` Option 1: with Wrangler, run `npm run start` to serve your Worker on http://localhost:8787. The cache will not be active in development.
* Edit `wrangler.toml` with a new name + your development and production R2 buckets. Option 2: Generate the Workers script using `npm run build` and copy `dist/index.js` to the editor.
* Test in development: `npm run start`
* Publish the worker: `npm run deploy`
# Settings
By default, your worker will serve tiles at path `NAME/0/0/0.EXT` using the archive at the root of your bucket `NAME.pmtiles`, where EXT is one of `mvt`, `png`, `jpg` or `webp` depending on the tileset.
This behavior can be customized with optional environment variables:
`PMTILES_PATH` - A string like `folder/{name}.pmtiles` specifying the path to archives in your bucket. Default `{name}.pmtiles`
`TILES_PATH` - a string like `prefix/{name}/{z}/{x}/{y}.{ext}` specifying the tile path exposed by the worker. Default `{name}/{z}/{x}/{y}.{ext}`
`ALLOWED_ORIGINS` - a comma-separated list of allowed CORS origions. Default none. Examples: `https://example.com,https://localhost:3000`, `*`
# Using the Workers web editor
Generate the Workers script using `npm run build` and copy `dist/index.js` to the editor.
