How to reproduce

• Tried Format Document with
• Tried Format on Save

Expected behavior

• Prisma VS Code Plugin Should Format the Schema

Prisma information

After upgrading to version 7, editing the schema and saving with lint() works normally, but format() consumes a lot of CPU and cannot be saved correctly.

So what is the solution for this ? It supposed to format with Prettier right ?
And I saw the Prettier Prisma Plugin which seems outdated and not maintained for long time.

This is a very old issue. It used to occur only in special cases, but now it happens in all situations #1774

I found the reason why the extension runs slowly.
It frequently re-executes the code in prisma.config.ts.
If that file contains any time-consuming tasks—such as loading env files will be triggered repeatedly and cause significant slowdowns.

If you add a simple condition check, you can greatly reduce or even avoid this issue.

if (!process.env.DATABASE_URL) {
  // load env files
}

I'm not quite sure why the extension re-executes prisma.config.ts so frequently.

Temporary Workarounds:

Manual: Run npx prisma format for a quick, one-time fix.

On-Save Automation: Temporarily rename prisma.config.ts while working on your schema to restore normal on-save formatting.
