TimeLimit-Server

This is the server for the connected mode in TimeLimit.

Clustering

This application only supports running a single instance of it. When clustering, push messages do not work anymore between devices connected to different devices and the rate limiting is per instance.

Running

Option 1: Use a prebuilt docker image
Option 2: Install Node.JS (see below for detailed usage)

Commands

npm start

This runs all pending migrations and starts the server.

npm run build

This “compiles” the application.

npm run lint:fix

This fixes the causes of lint warnings (where possible).

Configuration (environment variables)

• DATABASE_URL
  • this specifies the database to use
  • default value: sqlite://test.db (sqlite database in the source code directory)
  • supports mysql, postgresql and sqlite (sqlite in development builds only because it’s declared as dev dependency)
  • looks like postgres://user:pass@example.com:5432/dbname
  • no extra setup needed
    • when starting the application, the database tables are created/ migrated
    • this only works for upgrading; if you intend to eventually downgrade, make a backup first (you should make backups in all cases before an upgrade)
• PORT
