## Generate a TypeScript Frontend Client

Let's start with a simple FastAPI application:

=== "Python 3.9+"

	// Removing the below two lines or downgrading to gorm v1.20.12 will make this test pass.
	var total int64
	query.Count(&total)

	var result User

	// Incorrectly generates a 'SELECT *' query which causes companies.id to overwrite users.id
	if err := query.First(&result, user.ID).Error; err != nil {
		t.Fatalf("Failed, got error: %v", err)
	}

	if result.ID != user.ID {

Django REST framework was created to be a flexible toolkit for building Web APIs using Django underneath, to improve its API capabilities.

It is used by many companies including Mozilla, Red Hat and Eventbrite.

It was one of the first examples of **automatic API documentation**, and this was specifically one of the first ideas that inspired "the search for" **FastAPI**.
