Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Table of Contents

About The Project

Automatically generate fully implemented tRPC routers from your Prisma Schema. This includes routers, app router and of course all input schemas using Zod. Updates every time npx prisma generate runs.

Supported Prisma Versions

Prisma 4

  • 0.2.0 and higher

Prisma 2/3

  • 0.1.12 and lower

Supported tRPC Versions

tRPC 10

  • 0.8.0 and higher

tRPC 9

  • 0.7.2 and lower

Installation

Using npm:

 npm install prisma-trpc-generator

Using yarn:

 yarn add prisma-trpc-generator

Usage

1- Star this repo 😉

2- Add the generator to your Prisma schema

generator trpc {
  provider          = "prisma-trpc-generator"
  withZod           = true
  withMiddleware    = false
  withShield        = false
  contextPath       = "../src/context"
  trpcOptionsPath   = "../src/trpcOptions"
}

3- Enable strict mode in tsconfig as it is required by Zod, and considered a Typescript best practice

{
  "compilerOptions": {
    "strict": true
  }
}

4- Running npx prisma generate for the following schema.prisma

model User {
  id    Int     @id @default(autoincrement())
  email String  @unique
  name  String?
  posts Post[]
}

model Post {
  id        Int      @id @default(autoincrement())
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  title     String
  content   String?
  published Boolean  @default(false)
  viewCount Int      @default(0)
  author    User?    @relation(fields: [authorId], references: [id])
  authorId  Int?
}

will generate

tRPC Routers

5- Make sure you have a valid Context file, as specified in contextPath option. The official Context for reference.

6- Optionally, you can specify a trpcOptionsPath to set various tRPC options (like transformer, error formatter, etc). Find about all possible options here.

import { ZodError } from 'zod';

export default {
  errorFormatter({ shape, error }) {
    return {
      ...shape,
      data: {
        ...shape.data,
        zodError:
          error.code === 'BAD_REQUEST' && error.cause instanceof ZodError
            ? error.cause.flatten()
            : null,
      },
    };
  },
};

Customizations

Skipping entire models

/// @@Gen.model(hide: true)
model User {
  id    Int     @id @default(autoincrement())
  email String  @unique
  name  String?
}
