Getting started with Prisma Accelerate

Prerequisites

To get started with Accelerate, you will need the following:

A
A project that uses Prisma Client 4.16.1 or higher. If your project is using interactive transactions, you need to use 5.1.1 or higher. (We always recommend using the latest version of Prisma.)
A hosted PostgreSQL, MySQL/MariaDB, PlanetScale, CockroachDB, or MongoDB database

1. Enable Accelerate

Navigate to your Prisma Data Platform project, choose an environment, and enable Accelerate by providing your database connection string and selecting the region nearest your database.

note

If you require IP allowlisting or firewall configurations with trusted IP addresses, enable Static IP for enhanced security. Learn more on how to enable static IP for Accelerate in the Platform Console.

2. Add Accelerate to your application

2.1. Update your database connection string

Once enabled, you'll be prompted to generate an API key that you'll use in your new Accelerate connection string to authenticate requests.

Replace your direct database url with your new Accelerate connection string.

.env

# New Accelerate connection string with generated API_KEY
DATABASE_URL="prisma://accelerate.prisma-data.net/?api_key=__API_KEY__"

# Previous (direct) database connection string
# DATABASE_URL="postgresql://user:password@host:port/db_name?schema=public"

Your updated connection string will be used as the datasource url in your Prisma schema file;

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

Prisma Migrate and Introspection do not work with a prisma:// connection string. In order to continue using these features add a new variable to the .env file named DIRECT_DATABASE_URL whose value is the direct database connection string:

.env

DATABASE_URL="prisma://accelerate.prisma-data.net/?api_key=__API_KEY__"
DIRECT_DATABASE_URL="postgresql://user:password@host:port/db_name?schema=public"

Then in your Prisma schema's datasource block add a field named directUrl with the following:

datasource db {
  provider  = "postgresql"
  url       = env("DATABASE_URL")
  directUrl = env("DIRECT_DATABASE_URL")
}

Migrations and introspections will use the directUrl connection string rather than the one defined in url when this configuration is provided.

directUrl is useful for you to carry out migrations and introspections. However, you don't need directUrl to use Accelerate in your application.

note

If you are using Prisma with PostgreSQL, there is no need for directUrl, as Prisma Migrate and Introspection work with the prisma+postgres:// connection string.

2.2. Install the Accelerate Prisma Client extension

info

💡 Accelerate requires Prisma Client version 4.16.1 or higher and @prisma/extension-accelerate version 1.0.0 or higher

Install the latest version of Prisma Client and Accelerate Prisma Client extension

npm install @prisma/client@latest @prisma/extension-accelerate

2.3. Generate Prisma Client for Accelerate

If you're using Prisma version 5.2.0 or greater, Prisma Client will automatically determine how it should connect to the database depending on the protocol in the database connection string. If the connection string in the DATABASE_URL starts with prisma://, Prisma Client will try to connect to your database using Prisma Accelerate.

When using Prisma Accelerate in long-running application servers, such as a server deployed on AWS EC2, you can generate the Prisma Client by executing the following command:

npx prisma generate

When using Prisma Accelerate in a Serverless or an Edge application, we recommend you to run the following command to generate Prisma Client:

npx prisma generate --no-engine

The --no-engine flag prevents a Query Engine file from being included in the generated Prisma Client, this ensures the bundle size of your application remains small.

warning

If your Prisma version is below 5.2.0, generate Prisma Client with the --accelerate option:

npx prisma generate --accelerate

If your Prisma version is below 5.0.0, generate Prisma Client with the --data-proxy option:

npx prisma generate --data-proxy

2.4. Extend your Prisma Client instance with the Accelerate extension

Add the following to extend your existing Prisma Client instance with the Accelerate extension:

import { PrismaClient } from '@prisma/client'
import { withAccelerate } from '@prisma/extension-accelerate'

const prisma = new PrismaClient().$extends(withAccelerate())

If you are going to deploy to an edge runtime (like Cloudflare Workers, Vercel Edge Functions, Deno Deploy, or Supabase Edge Functions), use our edge client instead:

import { PrismaClient } from '@prisma/client/edge'
import { withAccelerate } from '@prisma/extension-accelerate'

const prisma = new PrismaClient().$extends(withAccelerate())

If VS Code does not recognize the $extends method, refer to this section on how to resolve the issue.

Using the Accelerate extension with other extensions or middleware

Since extensions are applied one after another, make sure you apply them in the correct order. Extensions cannot share behavior and the last extension applied takes precedence.

If you are using Prisma Optimize in your application, make sure you apply it before the Accelerate extension. For example:

const prisma = new PrismaClient().$extends(withOptimize()).$extends(withAccelerate())

If you are using Prisma Middleware in your application, make sure they are added before any Prisma Client extensions (like Accelerate). For example:

const prisma = new PrismaClient().$use(middleware).$extends(withAccelerate())

2.5. Use Accelerate in your database queries

The withAccelerate extension primarily does two things:

Gives you access to the cacheStrategy field within each applicable model method that allows you to define a cache strategy per-query.
Routes all of your queries through a connection pooler.

No cache strategy to only use connection pool

If you simply want to take advantage of Accelerate's connection pooling feature without applying a cache strategy, you may run your query the same way you would have without Accelerate.

By enabling Accelerate and supplying the Accelerate connection string, your queries now use the connection pooler by default.

Define a cache strategy

Update a query with the new cacheStrategy property which allows you to define a cache strategy for that specific query:

const user = await prisma.user.findMany({
  where: {
    email: {
      contains: 'alice@prisma.io',
    },
  },
  cacheStrategy: { swr: 60, ttl: 60 },
})

In the example above, swr: 60 and ttl: 60 means Accelerate will serve cached data for 60 seconds and then another 60 seconds while Accelerate fetches fresh data in the background.

You should now see improved performance for your cached queries.

info

For information about which strategy best serves your application, see Select a cache strategy.

info

As of Prisma version 5.2.0 you can use Prisma Studio with the Accelerate connection string.

Invalidate the cache and keep your cached query results up-to-date

If your application requires real-time or near-real-time data, cache invalidation ensures that users see the most current data, even when using a large ttl (Time-To-Live) or swr (Stale-While-Revalidate) cache strategy. By invalidating your cache, you can bypass extended caching periods to show live data whenever it's needed.

For example, if a dashboard displays customer information and a customer’s contact details change, cache invalidation allows you to refresh only that data instantly, ensuring support staff always see the latest information without waiting for the cache to expire.

To invalidate a cached query result, you can add tags and then use the $accelerate.invalidate API.

note

On-demand cache invalidation is available with our paid plans. For more details, please see our pricing.

To invalidate the query below:

await prisma.user.findMany({
  where: {
    email: {
      contains: "alice@prisma.io",
    },
  },
  cacheStrategy: {
    swr: 60,
    ttl: 60,
    tags: ["emails_with_alice"],
  },
});

You need to provide the cache tag in the $accelerate.invalidate API:

try {
  await prisma.$accelerate.invalidate({
    tags: ["emails_with_alice"],
  });
} catch (e) {
  if (e instanceof Prisma.PrismaClientKnownRequestError) {
    // The .code property can be accessed in a type-safe manner
    if (e.code === "P6003") {
      console.log(
        "You've reached the cache invalidation rate limit. Please try again shortly."
      );
    }
  }
  throw e;
}
