prisma-cli-format

prisma format

Formats your Prisma schema file.

Command

prisma format [options]

What It Does

• Fixes formatting (indentation, spacing)
• Adds missing back-relations (e.g., adds the other side of a relation)
• Adds missing relation arguments (e.g., fields, references)
• Sorts fields and attributes (opinionated)

Options

Examples

Format default schema

prisma format

Format specific schema

prisma format --schema=./custom/schema.prisma

Behavior

prisma format modifies the file in place. It is equivalent to "Prettier for Prisma schemas" but also has semantic understanding to fix/add missing schema definitions.

Use in Editor

Most Prisma editor extensions (VS Code, WebStorm) run prisma format automatically on save. This command is useful for:

• CI pipelines (check formatting)
• CLI-based workflows
• Fixing large schema refactors
