As a first step, create a project directory and navigate into it:
Next, initialize a TypeScript project and add the Prisma CLI as a development dependency to it:
This creates a
package.json with an initial setup for your TypeScript app.
Next, initialize TypeScript:
Next, initialize a Node.js project and add the Prisma CLI as a development dependency to it:
This creates a

You can now invoke the Prisma CLI by prefixing it with
Next, set up your Prisma ORM project by creating your Prisma schema file with the following command:
This command does two things:
- creates a new directory called
prismathat contains a file called
schema.prisma, which contains the Prisma schema with your database connection variable and schema models
- creates the
.envfile in the root directory of the project, which is used for defining environment variables (such as your database connection)
