This is a template for a worker that receives JSON events via HTTPS and logs them into Workers Analytics Engine.
Messages should be POSTed to the worker as JSON objects. One JSON object per line.
Optionally, the payload can be gzipped and a Content-Encoding: gzip header set, otherwise it will assume the data is uncompressed.
Up to 25 events can be received at one time.
Authentication is via bearer token. You can use any token or password string as long as you supply the same string to both the worker and the caller. To configure the token on the worker side you must set the BEARER_TOKEN secret to the token value by running (in a terminal, from within this project directory):
npx wrangler secret put BEARER_TOKEN
then entering your token value.
Then, when calling the worker you must supply an Authorization: Bearer <your token> header, with <your token> replaced by the value supplied above.
Various customisations are suggested such as changing the worker and dataset names, and adjusting which fields are logged and any other pre-processing. See the comment at the top of src/index.js for where to make these changes.
See the Cloudflare developer docs for more information on indexes, sampling and how to query the Workers Analytics Engine SQL API.
