Prisma IndexedDB Client Generator

This library is a Prisma generator that creates a client with a similar syntax and behavior to the Prisma Client but is designed to operate with IndexedDB for local storage. It allows developers to interact with IndexedDB using a familiar Prisma-like API.

Features

• Prisma-like syntax and API for IndexedDB.
• Supports CRUD operations with structured data.
• Integrates seamlessly with Prisma workflows.
• Generates a client tailored to your Prisma schema.

Installation

npm install @prisma-idb/idb-client-generator

Usage

1. Add to Prisma Schema

Update your prisma.schema file to include the generator:

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

generator client {
  provider = "prisma-client-js"
}

generator prismaIDB {
  provider = "idb-client-generator"
  output   = "./prisma-idb"
}

model User {
  id    Int    @id @default(autoincrement())
  name  String
  email String @unique
}

2. Generate the Client

Run the Prisma client generation command:

npx prisma generate

This will generate a client in your project.

3. Use the Client

Import the generated client and use it in your code:

import { PrismaIDBClient } from "./outputPath/prisma-idb-client";

async function main() {
  const idbClient = await PrismaIDBClient.createClient();

  await idbClient.user.create({
    data: { name: "Alice", email: "alice@example.com" },
  });

  const users = await idbClient.user.findMany();
  console.log(users);
}

API

The API mimics Prisma Client's API for ease of use:

create

Insert a new record:

idbClient.modelName.create({
  data: {
    field: value,
  },
});

findMany

Retrieve all records:

idbClient.modelName.findMany();

findUnique

Retrieve a single record by unique key:

idbClient.modelName.findUnique({
  where: { key: value },
});

update

Update a record:

idbClient.modelName.update({
  where: { key: value },
  data: { key: newValue },
});

delete

Delete a record:

idbClient.modelName.delete({
  where: { key: value },
});

Development Notes

• IndexedDB Dependency: The client internally uses the idb library for IndexedDB operations.
• Compatibility: Ensure your environment supports IndexedDB (modern browsers).
• Local-Only: This is designed for local storage scenarios and does not support server-side databases.
