# Open-Assistant REST Backend ## REST Server Configuration Please either use environment variables or create a `.env` file in the backend root directory (in which this readme file is located) to specify the `DATABASE_URI`. Example contents of a `.env` file for the backend: ``` DATABASE_URI="postgresql://:@/" BACKEND_CORS_ORIGINS=["http://localhost", "http://localhost:4200", "http://localhost:3000", "http://localhost:8080", "https://localhost", "https://localhost:4200", "https://localhost:3000", "https://localhost:8080", "http://dev.oasst.laion.ai", "https://stag.oasst.laion.ai", "https://oasst.laion.ai"] ``` ## Running the REST Server locally for development Have a look into the main `README.md` file for more information on how to set up the backend for development.
