description: Learn how to configure Better Auth in your project.
|
||||
---
|
||||
|
||||
We provide two ways of installing and initializing Better Auth.
|
||||
|
||||
* [Our `init` CLI to automatically](#automatic-installation):
|
||||
* Install the required dependencies
|
||||
* Update your ENV files for any required environment variables
|
||||
* Prompt to install plugins and set up a database of your choice
|
||||
* Initialize your `auth.ts` and `auth-client.ts` files
|
||||
* Or the good old [manual installation](#manual-installation) if you prefer to do it yourself.
|
||||
|
||||
## Automatic Installation
|
||||
|
||||
Install and initialize Better Auth in your project using Better Auth's `init` CLI command:
|
||||
|
||||
<Steps>
|
||||
|
||||
<Step>
|
||||
### Run the Init CLI
|
||||
|
||||
Make sure that you have an env file defined already, then run:
|
||||
|
||||
```bash
|
||||
npx @better-auth/cli init
|
||||
```
|
||||
|
||||
Read more about our init command [here](/docs/concepts/cli#init).
|
||||
|
||||
</Step>
|
||||
|
||||
<Step>
|
||||
### Create Database Tables
|
||||
|
||||
- **Generate**: This command generates an ORM schema or SQL migration file.
|
||||
|
||||
<Callout>
|
||||
If you're using Kysely, you can apply the migration directly with `migrate` command below. Use `generate` only if you plan to apply the migration manually.
|
||||
</Callout>
|
||||
|
||||
```bash title="Terminal"
|
||||
npx @better-auth/cli generate
|
||||
```
|
||||
|
||||
- **Migrate**: This command creates the required tables directly in the database. (Available only for the built-in Kysely adapter)
|
||||
|
||||
```bash title="Terminal"
|
||||
npx @better-auth/cli migrate
|
||||
```
|
||||
|
||||
see the [CLI documentation](/docs/concepts/cli) for more information.
|
||||
|
||||
<Callout>
|
||||
If you instead want to create the schema manually, you can find the core schema required in the [database section](/docs/concepts/database#core-schema).
|
||||
</Callout>
|
||||
</Step>
|
||||
|
||||
<Step>
|
||||
|
||||
### Authentication Methods
|
||||
Configure the authentication methods you want to use. Better Auth comes with built-in support for email/password, and social sign-on providers.
|
||||
|
||||
```ts title="auth.ts"
|
||||
import { betterAuth } from "better-auth"
|
||||
|
||||
export const auth = betterAuth({
|
||||
//...other options
|
||||
emailAndPassword: { // [!code highlight]
|
||||
enabled: true // [!code highlight]
|
||||
},// [!code highlight]
|
||||
socialProviders: { // [!code highlight]
|
||||
github: { // [!code highlight]
|
||||
clientId: process.env.GITHUB_CLIENT_ID, // [!code highlight]
|
||||
clientSecret: process.env.GITHUB_CLIENT_SECRET, // [!code highlight]
|
||||
} // [!code highlight]
|
||||
}, // [!code highlight]
|
||||
});
|
||||
```
|
||||
|
||||
<Callout type="info">
|
||||
You can use even more authentication methods like [passkey](/docs/plugins/passkey), [username](/docs/plugins/username), [magic link](/docs/plugins/magic-link) and more through plugins.
|
||||
</Callout>
|
||||
</Step>
|
||||
|
||||
<Step>
|
||||
### Mount Handler
|
||||
To handle api requests, you need to set up a route handler on your server.
|
||||
|
||||
Create a new file or route in your framework's designated catch-all route handler. This route should handle requests for the path `/api/auth/*` (unless you've configured a different base path).
|
||||
|
||||
<Callout>
|
||||
Better Auth supports any backend framework with standard Request and Response objects and offers helper functions for popular frameworks.
|
||||
</Callout>
