Prisma Introspect - Shell/Bash

Prisma Introspect is a command-line interface tool that enables you to introspect an existing database and use it with Prisma. This tool generates a Prisma schema file based on the database schema.

Syntax

To use Prisma Introspect, you need to open a terminal and enter the following command:

prisma introspect

Flags

The following flags are available for Prisma Introspect:

• --datasource - Specifies the name of the datasource in the Prisma schema.
• --url - Specifies the URL of the database.
• --preview-feature - Enables the use of preview features in Prisma.

How it works

When you run prisma introspect, it connects to the database and reads the schema. Then, it generates a Prisma schema file that reflects the database schema.

Here is an example of how to use Prisma Introspect:

prisma introspect --datasource db --url postgresql://user:password@localhost:5432/mydb

This command generates the following Prisma schema file:

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

model User {
  id    Int     @id @default(autoincrement())
  name  String?
  email String?
}

Note that the Prisma schema file does not contain all the database schema information. Instead, it only contains the information that is relevant for Prisma.

Conclusion

Prisma Introspect is a useful tool for generating a Prisma schema file that reflects an existing database schema. It is easy to use and provides a quick way to get started with Prisma.
