[Saleor CLI](https://github.com/saleor/saleor-cli) is designed to save you from the repetitive chores around Saleor development, including creating Apps. It will take the burden of spawning new apps locally, connecting them with Saleor environments, and establishing a tunnel for local development in seconds.
Follow the guide [how install your app](https://docs.saleor.io/docs/3.x/developer/extending/apps/installing-apps#installation-using-graphql-api) and use tunneling tools like [localtunnel](https://github.com/localtunnel/localtunnel) or [ngrok](https://ngrok.com/) in order to expose your local server.
If you use [saleor-dashboard](https://github.com/saleor/saleor-dashboard) and your local server is exposed, you can install your app by following this link:
Commands `build` and `dev` would generate schema and typed functions using Saleor's GraphQL endpoint. Commit `generated` folder to your repo as they are necessary for queries and keeping track of the schema changes.

### Storing registration data - APL
During registration process Saleor API pass the auth token to the app. With this token App can query Saleor API with privileged access (depending on requested permissions during the installation).
To store this data, app-template use a different [APL interfaces](https://github.com/saleor/saleor-app-sdk/blob/main/docs/apl.md).
The choice of the APL is done using `APL` environment variable. If value is not set, FileAPL is used. Available choices:
-`file`: no additional setup is required. Good choice for local development. Can't be used for multi tenant-apps or be deployed (not intended for production)
-`upstash`: use [Upstash](https://upstash.com/) Redis as storage method. Free account required. Can be used for development and production and supports multi-tenancy. Requires `UPSTASH_URL` and `UPSTASH_TOKEN` environment variables to be set
If you want to use your own database, you can implement your own APL. [Check the documentation to read more.](https://github.com/saleor/saleor-app-sdk/blob/main/docs/apl.md)
