Edge functions

If your application is deployed via an "Edge Function" offering or is deployed from a serverless offering and has a non-standard runtime, it is a edge-deployed app. Common examples for such offerings include Cloudflare Workers or Pages, Vercel Edge Functions or Edge Middleware, and Deno Deploy.

Use Prisma ORM without Rust binaries

If Prisma ORM's Rust engine binaries cause large bundle sizes, slow builds, or deployment issues (for example, in serverless or edge environments), you can use it without them using this configuration of your generator block:

generator client {
  provider   = "prisma-client-js" // or "prisma-client"
  engineType = "client"
}

Prisma ORM without Rust binaries has been Generally Available since v6.16.0.

Note that you need to use a driver adapter in this case.

When using this architecture:

• No Rust query engine binary is downloaded or shipped.
• The database connection pool is maintained by the native JS database driver you install (e.g., @prisma/adapter-pg for PostgreSQL).

This setup can simplify deployments in serverless or edge runtimes. Learn more in the docs here.

Curious why we moved away from the Rust engine? Take a look at why we transitioned from Rust binary engines to an all-TypeScript approach for a faster, lighter Prisma ORM in this blog post.

Overview

You can deploy an application that uses Prisma ORM to the edge. Depending on which edge function provider and which database you use, there are different considerations and things to be aware of.

Deploy to Cloudflare

This page covers everything you need to know to deploy an app with Prisma ORM to a Cloudflare Worker or to Cloudflare Pages.

Deploy to Vercel

This page covers everything you need to know to deploy an app that uses Prisma Client for talking to a database in Vercel Edge Middleware or a Vercel Function deployed to the Vercel Edge Runtime.

Deploy to Deno Deploy

With this guide, you can learn how to build and deploy a simple application to Deno Deploy. The application uses Prisma ORM to save a log of each request to a Prisma Postgres database.
