Master full-stack development with a single repository for everything!

Learn the art of full-stack development with this comprehensive course. Through implementing the latest technologies and techniques, the course directly addresses the most common challenges full-stack developers face:
- **Code consistency and sharing:** Monorepos eliminate the need for multiple repositories, ensuring consistent code across your application and facilitating seamless code sharing.
- **Technology integration:** Learn how to integrate modern technologies like TypeScript, Tailwind CSS, and tRPC, empowering you to build robust and maintainable applications.
- **Database management:** Master advanced PostgreSQL features to optimize data storage, retrieval, and manipulation, ensuring a high-performance and scalable backend.

Build type-safe full-stack applications with database-centric strategies

This comprehensive full-stack development course covers monorepos, TypeScript, Tailwind CSS, tRPC, and PostgreSQL, empowering you to build modern, scalable applications. Structured into 7 modules of bite-sized lessons, each module is designed to be engaging and informative, combining video lectures, hands-on coding exercises, and real-world examples.

Build modern, scalable full-stack applications using a unified approach

The booking schema is the central component of the app. We will implement the approach discussed earlier when experimenting with 

. We will also create another table named customer, similar to the provider table, but representing the customers. Additionally, a small table named 

 will be added, enabling the differentiation between various service types that a provider might offer. The resulting SQL for the booking table appears as follows:

CREATE EXTENSION btree_gist;
CREATE TABLE booking (
  id int GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
  customer_id int REFERENCES customer(id) NOT NULL,
  provider_id int REFERENCES provider(id) NOT NULL,
  during tsrange NOT NULL,
  EXCLUDE USING gist (provider_id WITH =, during WITH &&)
);

COMMENT ON TABLE booking IS 'Represents a booking made by a given customer, for a given provider. Guaranteed not to overlap with other bookings for said provider.';
COMMENT ON COLUMN booking.during IS 'Time of the booking';

CREATE INDEX booking_customer_id_idx ON booking (customer_id);
CREATE INDEX booking_provider_id_idx ON booking (provider_id);

Now, most of this we've already covered in the 

 lesson. The only addition here is that you have customer and provider id's, with matching indices. The 

 constraint has been updated to ensure that no two bookings overlap for the same provider.

Update your migration file to create the customer and booking table. In order to do this, start by rolling the existing migration back:

## The booking table

The booking schema is the central component of the app. We will implement the approach discussed earlier when experimenting with `ts_range`. We will also create another table named customer, similar to the provider table, but representing the customers. Additionally, a small table named `service_type` will be added, enabling the differentiation between various service types that a provider might offer. The resulting SQL for the booking table appears as follows:

```sql
CREATE EXTENSION btree_gist;
CREATE TABLE booking (
  id int GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
  customer_id int REFERENCES customer(id) NOT NULL,
  provider_id int REFERENCES provider(id) NOT NULL,
  during tsrange NOT NULL,
  EXCLUDE USING gist (provider_id WITH =, during WITH &&)
);

COMMENT ON TABLE booking IS 'Represents a booking made by a given customer, for a given provider. Guaranteed not to overlap with other bookings for said provider.';
COMMENT ON COLUMN booking.during IS 'Time of the booking';

CREATE INDEX booking_customer_id_idx ON booking (customer_id);
CREATE INDEX booking_provider_id_idx ON booking (provider_id);
```

Now, most of this we've already covered in the `pg-ranges` lesson. The only addition here is that you have customer and provider id's, with matching indices. The `EXCLUDE` constraint has been updated to ensure that no two bookings overlap for the same provider.

Update your migration file to create the customer and booking table. In order to do this, start by rolling the existing migration back:

```bash
$ npx knex migrate:rollback
```
