The OrderCodeStrategy determines how Order codes are generated.
A custom strategy can be defined which e.g. integrates with an
existing system to generate a code:

:::info

This is configured via the `orderOptions.orderCodeStrategy` property of
your VendureConfig.

*Example*

```ts
class MyOrderCodeStrategy implements OrderCodeStrategy {
  // Some imaginary service which calls out to an existing external
  // order management system.
  private mgmtService: ExternalOrderManagementService;

  init(injector: Injector) {
    this.mgmtService = injector.get(ExternalOrderManagementService);
  }

  async generate(ctx: RequestContext) {
    const result = await this.mgmtService.getAvailableOrderParams();
    return result.code;
  }
}
```

```ts title="Signature"
interface OrderCodeStrategy extends InjectableStrategy {
    generate(ctx: RequestContext): string | Promise<string>;
}
```

The default OrderCodeStrategy generates a random string consisting
of 16 uppercase letters and numbers.
