# DATABASE_ADAPTER_MISSING

The database adapter package for the dialect `DATABASE_URL` names is not installed.

## Cause

The database adapter package for the dialect `DATABASE_URL` names is not installed.

Nextly reaches each database through its own adapter package: `@nextlyhq/adapter-postgres`, `@nextlyhq/adapter-mysql` or `@nextlyhq/adapter-sqlite`. The command read which database `DATABASE_URL` names, then could not load that database's adapter.

## Fix

Install the adapter for your database in the project, then run the command again:

```bash
pnpm add @nextlyhq/adapter-postgres
```

If you meant a different database, check `DATABASE_URL` (and `DB_DIALECT`, if it is set).

## Example

```text
✗ The MySQL adapter, `@nextlyhq/adapter-mysql`, is not installed.
  Why:  `DATABASE_URL` names a MySQL database, and Nextly reaches it through that package.
  Next: Install it in the project, for example `pnpm add @nextlyhq/adapter-mysql`, then run the command again.
