What is Prisma?
Antwoord
Prisma is a next-generation ORM (Object-Relational Mapping) for Node.js and TypeScript that simplifies database access. It generates a type-safe client from the Prisma schema, providing autocompletion and compile-time type checking. Unlike traditional ORMs like TypeORM or Sequelize, Prisma uses a declarative schema file and generates migrations automatically.

Where to define data models in a Prisma project?
Antwoord
Prisma data models are defined in the schema.prisma file, which is the central configuration file. This file uses the Prisma Schema Language (PSL) to describe the database structure. The Prisma schema also contains the generator configuration (Prisma Client) and datasource configuration (database connection).
3Which command generates the Prisma Client after schema modification?
Which command generates the Prisma Client after schema modification?
Antwoord
The prisma generate command regenerates the Prisma Client based on the current schema. This operation creates or updates the type-safe client in node_modules/@prisma/client. This command must be rerun after each schema.prisma modification for changes to be reflected in TypeScript code. This command runs automatically after npm install.
