# Environment Variables
|
|
|
|
This document provides an explanation of the environment variables used in the big-AGI application.
|
|
|
|
**All variables are optional**; and _UI options_ take precedence over _backend environment variables_,
|
|
which take place over _defaults_. This file is kept in sync with [`../src/server/env.mjs`](../src/server/env.mjs).
|
|
|
|
### Setting Environment Variables
|
|
|
|
Environment variables can be set by creating a `.env` file in the root directory of the project.
|
|
|
|
The following is an example `.env` for copy-paste convenience:
|
|
|
|
```bash
|
|
# Database
|
|
POSTGRES_PRISMA_URL=
|
|
POSTGRES_URL_NON_POOLING=
|
|
|
|

## Variables Documentation
|
|
|
|
### Database
|
|
|
|
To enable features such as Chat Link Shring, you need to connect the backend to a database. We require
|
|
serverless Postgres, which is available on Vercel, Neon and more.
|
|
|
|
Also make sure that you run `npx prisma db:push` to create the initial schema on the database for the
|
|
first time (or update it on a later stage).
|
|
|
|
| Variable | Description |
|
|
|----------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
|
| `POSTGRES_PRISMA_URL` | The URL of the Postgres database used by Prisma - example: `postgres://USER:PASS@SOMEHOST.postgres.vercel-storage.com/SOMEDB?pgbouncer=true&connect_timeout=15` |
|
|
| `POSTGRES_URL_NON_POOLING` | The URL of the Postgres database without pooling |
|
|
|
|
### LLMs

The following variables when set will enable the corresponding LLMs on the server-side, without
|
|
requiring the user to enter an API key

### Model Observability: Helicone
