Nowplaying

A demo app for Turso's embedded replicas running on AWS Lambda

Intro

This app tracks when users were last active, and what game they played. Users can update their info any time. Results are cached on disk in a libSQL database running in embedded replica mode.

Demo

The demo is hosted here: http://nowplaying.sarna.dev

Deploy your own Lambda

Here are the steps that should more or less work, assuming you have aws CLI installed and set up (and mind all the user-specific variables):

npm prune --omit=dev
zip -r nowplaying.zip .
aws lambda create-function --function-name nowplaying --zip-file fileb://nowplaying.zip --handler index.handler --runtime nodejs18.x --role $YOUR_AWS_ROLE
aws lambda update-function-configuration --function-name nowplaying --environment "Variables={LIBSQL_SYNC_URL=$YOUR_TURSO_DB_URL,LIBSQL_AUTH_TOKEN=$(turso db tokens create $YOUR_TURSO_DB_NAME)}"
# and for updating the code
aws lambda update-function-code --function-name nowplaying --zip-file fileb://nowplaying.zip
