This is an in-memory adapter for micro-analytics.
It can be useful for testing and when deploying test deployments to now.sh. now does not support writing to the filesystem, which makes micro-analytics unable to start with the flat-file-db-adapter. In production use, you would probably want to use a real database if you care about the data collected.
npm install micro-analytics-cli micro-analytics-adapter-memory
micro-analytics --adapter memory
and open localhost:3000.
