# Database

You can set environment variables either through the command line, the Nix flake (if you are running nix/NixOS), _or_ the `.env` file.

Uses the following data storing services:

- PostgreSQL 16
- Valkey 8.0.2 (or Redis, haven't tested)

## Create migration database

Run:

```
sqlx database create
```

Only run this if the `DATABASE_URL` environment variable is set (with the `postgres://` protocol) and if the database migration has _not_ been set up yet.

## Create a new migration file

Run:

```
sqlx migrate add -r <name>
```

where `<name>` is the name of the database file name given.

This new migration will be placed in the `migrations/` directory.

## Run the migrations

Run:

```
sqlx migrate run
```

to run the _all_ migrations.

To revert migraitons:

```
sqlx migrate revert
```

to rollback (all?) migrations.
