+---
+
+The `prismaExtension` has been completely redesigned to support multiple Prisma versions and deployment strategies. This update introduces **three distinct modes** to handle the evolving Prisma ecosystem, from legacy setups to the upcoming Prisma 7.
+
+**Highlights:**
+
+- 🎯 Three modes: Legacy, Engine-Only, and Modern
+- 🎉 **NEW:** Support for `prisma.config.ts` files (Legacy Mode)
+- 🔍 **NEW:** Enhanced version detection with filesystem fallback
+
+## Breaking Changes
+
+⚠️ **MIGRATION REQUIRED**: The `prismaExtension` now requires an explicit `mode` parameter. Existing configurations without a `mode` will need to be updated.
+
+**Note:** All other existing options remain backward compatible. The new `configFile` option is optional and doesn't affect existing setups using the `schema` option.
+
+### Before (Old API)
+
+```ts
+import { prismaExtension } from "@trigger.dev/build/extensions/prisma";
+
+extensions: [
+  prismaExtension({
+    schema: "prisma/schema.prisma",
+    migrate: true,
+    typedSql: true,
+    directUrlEnvVarName: "DATABASE_URL_UNPOOLED",
+  }),
+];
+```
+
+### After (New API)
+
+```ts
+import { prismaExtension } from "@trigger.dev/build/extensions/prisma";
+
+extensions: [
+  prismaExtension({
+    mode: "legacy", // ← MODE IS NOW REQUIRED
+    schema: "prisma/schema.prisma",
+    migrate: true,
+    typedSql: true,
+    directUrlEnvVarName: "DATABASE_URL_UNPOOLED",
+  }),
+];
+```
+
+## New Features
+
+### 1. Legacy Mode
+
+**Use when:** You're using Prisma 6.x or earlier with the `prisma-client-js` provider.
+
+**Features:**
+
+- Automatic `prisma generate` during deployment
+- Supports single-file schemas (`prisma/schema.prisma`)
+- Supports multi-file schemas (Prisma 6.7+, directory-based schemas)
+- **NEW:** Supports Prisma config files (`prisma.config.ts`) via `@prisma/config` package
+- Migration support with `migrate: true`
+- TypedSQL support with `typedSql: true`
+- Custom generator selection
+- Handles Prisma client versioning automatically (with filesystem fallback detection)
+- Automatic extraction of schema and migrations paths from config files
+
+**Schema Configuration:**
+
+```prisma
+generator client {
+  provider        = "prisma-client-js"
+  previewFeatures = ["typedSql"]
+}
+
+datasource db {
+  provider  = "postgresql"
+  url       = env("DATABASE_URL")
+  directUrl = env("DATABASE_URL_UNPOOLED")
+}
+```
+
+**Extension Configuration:**
+
+```ts
+// Single-file schema
+prismaExtension({
+  mode: "legacy",
+  schema: "prisma/schema.prisma",
+  migrate: true,
+  typedSql: true,
+  directUrlEnvVarName: "DATABASE_URL_UNPOOLED",
+});
+
+// Multi-file schema (Prisma 6.7+)
+prismaExtension({
+  mode: "legacy",
+  schema: "./prisma", // ← Point to directory
+  migrate: true,
+  typedSql: true,
+  directUrlEnvVarName: "DATABASE_URL_UNPOOLED",
+});
+```
+
+**Tested Versions:**
+
+- Prisma 6.14.0 ✅
+- Prisma 6.7.0+ (multi-file schema support) ✅
+- Prisma 5.x ✅
+
+---
+
+### 2. Engine-Only Mode
+
+**Use when:** You have a custom Prisma client output path and want to manage `prisma generate` yourself.
+
+**Features:**
+
+- Only installs Prisma engine binaries (no client generation)
+- Automatic version detection from `@prisma/client`
+- Manual override of version and binary target
+- Minimal overhead - just ensures engines are available
+- You control when and how `prisma generate` runs
+
+**Schema Configuration:**
+
+```prisma
+generator client {
+  provider      = "prisma-client-js"
+  output        = "../src/generated/prisma"
+  // Ensure the "debian-openssl-3.0.x" binary target is included for deployment to the trigger.dev cloud
+  binaryTargets = ["native", "debian-openssl-3.0.x"]
+}
+
+datasource db {
+  provider  = "postgresql"
+  url       = env("DATABASE_URL")
+  directUrl = env("DATABASE_URL_UNPOOLED")
+}
+```
+
+**Extension Configuration:**
+
+```ts
+// Auto-detect version
+prismaExtension({
+  mode: "engine-only",
+});
+
+// Explicit version (recommended for reproducible builds)
+prismaExtension({
+  mode: "engine-only",
+  version: "6.19.0",
+});
+```
+
+**Important Notes:**
+
+- You **must** run `prisma generate` yourself (typically in a prebuild script)
+- Your schema **must** include the correct `binaryTargets` for deployment to the trigger.dev cloud. The binary target is `debian-openssl-3.0.x`.
+- The extension sets `PRISMA_QUERY_ENGINE_LIBRARY` and `PRISMA_QUERY_ENGINE_SCHEMA_ENGINE` environment variables to the correct paths for the binary targets.
+
+**package.json Example:**
+
+```json
+{
+  "scripts": {
+    "prebuild": "prisma generate",
+    "dev": "trigger dev",
+    "deploy": "trigger deploy"
+  }
+}
+```
+
+**Tested Versions:**
+
+- Prisma 6.19.0 ✅
+- Prisma 6.16.0+ ✅
+
+---
+
+### 3. Modern Mode
+
+**Use when:** You're using Prisma 6.16+ with the new `prisma-client` provider (with `engineType = "client"`) or preparing for Prisma 7.
+
+**Features:**
+
+- Designed for the new Prisma architecture
+- Zero configuration required
+- Automatically marks `@prisma/client` as external
+- Works with Prisma 7 beta releases & Prisma 7 when released
+- You manage client generation (like engine-only mode)
+
+**Schema Configuration (Prisma 6.16+ with engineType):**
+
+```prisma
+generator client {
+  provider        = "prisma-client"
+  output          = "../src/generated/prisma"
+  engineType      = "client"
+  previewFeatures = ["views"]
+}
+
+datasource db {
+  provider  = "postgresql"
+  url       = env("DATABASE_URL")
+  directUrl = env("DATABASE_URL_UNPOOLED")
+}
+```
+
+**Schema Configuration (Prisma 7):**
+
+```prisma
+generator client {
+  provider = "prisma-client"
+  output   = "../src/generated/prisma"
+}
+
+datasource db {
+  provider = "postgresql"
+}
+```
+
+**Extension Configuration:**
+
+```ts
+prismaExtension({
+  mode: "modern",
+});
+```
+
+**Prisma Config (Prisma 7):**
+
+```ts
+// prisma.config.ts
+import { defineConfig, env } from "prisma/config";
+import "dotenv/config";
+
+export default defineConfig({
+  schema: "prisma/schema.prisma",
+  migrations: {
+    path: "prisma/migrations",
+  },
+  datasource: {
+    url: env("DATABASE_URL"),
+  },
+});
+```
+
+**Important Notes:**
+
+- You **must** run `prisma generate` yourself
+- Requires Prisma 6.16.0+ or Prisma 7 beta
+- The new `prisma-client` provider generates plain TypeScript (no Rust binaries)
+- Requires database adapters (e.g., `@prisma/adapter-pg` for PostgreSQL)
+
+**Tested Versions:**
+
+- Prisma 6.16.0 with `engineType = "client"` ✅
+- Prisma 6.20.0-integration-next.8 (Prisma 7 beta) ✅
+

+
+## Migration Guide
+
+### From Old prismaExtension to Legacy Mode
+
+If you were using the previous `prismaExtension`, migrate to **Legacy Mode**:
+
+```ts
+// Old
+prismaExtension({
+  schema: "prisma/schema.prisma",
+  migrate: true,
+});
+
+// New
+prismaExtension({
+  mode: "legacy", // ← Add this
+  schema: "prisma/schema.prisma",
+  migrate: true,
+});
+```
+
+### From Managing Your Own Prisma Setup
+
+If you previously handled Prisma generation yourself and just needed engine binaries, use **Engine-Only Mode**:
+
+```ts
+prismaExtension({
+  mode: "engine-only",
+  version: "6.19.0", // Match your @prisma/client version
+});
+```
+
+### Preparing for Prisma 7
+
+If you want to adopt the new Prisma architecture, use **Modern Mode**:
+
+1. Update your schema to use `prisma-client` provider
+2. Add database adapters to your dependencies
+3. Configure the extension:
+
+```ts
+prismaExtension({
+  mode: "modern",
+});
+```
+
+---
+
+## Version Compatibility Matrix
+
+| Prisma Version   | Recommended Mode      | Notes                                        |
+| ---------------- | --------------------- | -------------------------------------------- |
+| < 5.0            | Legacy                | Older Prisma versions                        |
+| 5.0 - 6.15       | Legacy                | Standard Prisma setup                        |
+| 6.7+             | Legacy                | Multi-file schema support                    |
+| 6.16+            | Engine-Only or Modern | Modern mode requires `engineType = "client"` |
+| 6.20+ (7.0 beta) | Modern                | Prisma 7 with new architecture               |
+
+---
+
+## Prisma Config File Support (Prisma 6+)
+
+**NEW:** Legacy Mode now supports loading configuration from a `prisma.config.ts` file using the official `@prisma/config` package.
+
+**Use when:** You want to use Prisma's new config file format (Prisma 6+) to centralize your Prisma configuration.
+
+**Benefits:**
+
+- Single source of truth for Prisma configuration
+- Automatic extraction of schema location and migrations path
+- Type-safe configuration with TypeScript
+- Works seamlessly with Prisma 7's config-first approach
+
+**prisma.config.ts:**
+
+```ts
+import { defineConfig, env } from "prisma/config";
+import "dotenv/config";
+
+export default defineConfig({
+  schema: "prisma/schema.prisma",
+  migrations: {
+    path: "prisma/migrations",
+  },
+  datasource: {
+    url: env("DATABASE_URL"),
+    directUrl: env("DATABASE_URL_UNPOOLED"),
+  },
+});
+```
+
+**trigger.config.ts:**
+
+```ts
+import { prismaExtension } from "@trigger.dev/build/extensions/prisma";
+
+prismaExtension({
+  mode: "legacy",
+  configFile: "./prisma.config.ts", // ← Use config file instead of schema
+  migrate: true,
+  directUrlEnvVarName: "DATABASE_URL_UNPOOLED", // For migrations
+});
+```
+
+**What gets extracted:**
+
+- `schema` - The schema file or directory path
+- `migrations.path` - The migrations directory path (if specified)
+
+**Note:** Either `schema` or `configFile` must be specified, but not both.
+
+**When to use which:**
+
+| Use `schema` option          | Use `configFile` option           |
+| ---------------------------- | --------------------------------- |
+| Standard Prisma setup        | Using Prisma 6+ with config files |
+| Single or multi-file schemas | Preparing for Prisma 7            |
+| No `prisma.config.ts` file   | Centralized configuration needed  |
+| Simple setup                 | Want migrations path in config    |
