nuxt-prisma v0.0.3

Nuxt Prisma

Features

• Adds prisma client to event.context in the server using a Nuxt server middleware.
• (OPTIONAL) Sets default role with SET ROLE.
• (OPTIONAL) Reads an attribute from JWT and sets local role accordingly using SET LOCAL ROLE.
• (OPTIONAL) Copies JWT data to the current session settings using set_config().
• (OPTIONAL) Allows a RLS implementation with options and presets. (PostgreSQL)
• (OPTIONAL) Provides preset: supabase.

Quick Setup

1. Add nuxt-prisma dependency to your project

npm install --save-dev nuxt-prisma

2. Add nuxt-prisma to the modules section of nuxt.config.ts

export default defineNuxtConfig({
  modules: ['nuxt-prisma'],
  prisma: { preset: "supabase" }
});

3. If options.dbConfigName or options.jwtRoleAttribute is used, you need to enable prisma client extensions. To use Prisma Client extensions, you must enable the clientExtensions preview feature flag in the generator block of your schema.prisma file. Learn more

generator client {
  provider        = "prisma-client-js"
  previewFeatures = ["clientExtensions"]
}

Usage

/server/api/item.get.ts

export default eventHandler(async (event) => {
  const prisma = event.context.prisma;
  const item = await prisma.item.findUniqueOrThrow({ where: { id } });
}

Options

Below is an example for Supabase.

export default defineNuxtConfig({
  modules: ['nuxt-prisma'],
  prisma: { preset: "supabase" } // Options preset. Apply multiple options for a specific framework.
});

Supabase preset sets options as below.

export default defineNuxtConfig({
  modules: ['nuxt-prisma'],
  prisma: {
    defaultRole: "anon",                // Default database role to use for unauthenticated users. Set by `SET ROLE`.
    contextTokenAttribute: "_token",    // H3 event context attribute to get JWT token. WARNING: The token should be validated previously. This module does not validate JWT token.
    jwtRoleAttribute: "role",           // JWT attribute to get database role from.
    dbConfigName: "request.jwt.claims", // Database config name to assign contents of the JWT token. All decoded data is assigned to this config as a stringified JSON.
  }
});

Example above adds a Nuxt server middleware as explained below.

IMPORTANT NOTES:

You should add a validated JWT to the context previously. JWT is not validated by this module. Storing a non-validated JWT in the context is unsecure.
