Apply Separate Formatting With A Blank Line

Prisma's CLI includes a format command. When run, this will standardize the layout of the schema.prisma file. This is variable based on the length of column and attribute names.

You can exercise some control over the formatting and visually organize the parts of a model by injecting blank lines between sets of statements.

Here is what a formatted model might look like with no blank lines:

model Book {
  id              String   @id @default(uuid())
  title           String
  publicationDate DateTime
  author          Author   @relation(fields: [authorId], references: [id])
  authorId        String
  createdAt       DateTime @default(now()) @map(name: "created_at")
  updatedAt       DateTime @updatedAt @map(name: "updated_at")
}

All the types get aligned based on the longest column name.

Now, here is what it looks like if I use a blank line to separate all the primary fields from the createdAt and updatedAt.

model Book {
  id              String   @id @default(uuid())
  title           String
  publicationDate DateTime
  author          Author   @relation(fields: [authorId], references: [id])
  authorId        String

  createdAt DateTime @default(now()) @map(name: "created_at")
  updatedAt DateTime @updatedAt @map(name: "updated_at")
}

Notice how the second block of lines is aligned independent of the first.
