What's Node.js Web Framework?

A Node.js web framework is like a toolbox that helps web developers build server-side web applications using Node.js. It provides a structure and tools that make it easier to handle things like routing (directing requests to the right places), managing requests and responses, handling user sessions, working with databases, and creating web page templates. These frameworks simplify the process of building web applications, allowing developers to create scalable and high-performing websites. They take care of common tasks like handling incoming requests and sending out responses, so developers can focus on the unique features of their applications. They also make it easier to work with databases and other external services, making the development process faster and more efficient.

Feature Comparison
Features@trpc/serverkoa
Middleware Support
@trpc/server allows for middleware customization to handle tasks like authentication and request/response manipulation.
Koa also supports middleware but uses a more modern and lightweight middleware approach with async/await support.
Routing
@trpc/server provides a type-safe router for defining routes and handlers, ensuring type correctness.
Koa also offers routing but with a more lightweight and modular approach compared to Express.
Performance
@trpc/server focuses on type-safe communication and efficiency, making it a performant choice for web applications.
Koa is designed for high performance and leverages modern JavaScript features like async/await, making it suitable for performance-critical applications.
TypeScript Support
@trpc/server is written in TypeScript and offers type-safe communication between client and server.
Koa has better TypeScript support compared to Express, with built-in support for async/await and ES modules.
Extensibility and Ecosystem
@trpc/server offers type-safe communication and extensibility through custom middleware and handlers.
Koa has a growing ecosystem of middleware and libraries, with a focus on modern JavaScript features and best practices.

Documentation

Full documentation for @trpc/server can be found here

Installation

# npm
npm install @trpc/server

# Yarn
yarn add @trpc/server

# pnpm
pnpm add @trpc/server

# Bun
bun add @trpc/server

We also recommend installing zod to validate procedure inputs.

Basic Example

import { initTRPC } from '@trpc/server';
import {
  CreateHTTPContextOptions,
  createHTTPServer,
} from '@trpc/server/adapters/standalone';
import { z } from 'zod';

// Initialize a context for the server
function createContext(opts: CreateHTTPContextOptions) {
  return {};
}

// Get the context type
type Context = Awaited<ReturnType<typeof createContext>>;

// Initialize tRPC
const t = initTRPC.context<Context>().create();

// Create main router
const appRouter = t.router({
  // Greeting procedure
  greeting: t.procedure
    .input(
      z.object({
        name: z.string(),
      }),
    )
    .query(({ input }) => `Hello, ${input.name}!`),
});

// Export the app router type to be imported on the client side
export type AppRouter = typeof appRouter;

// Create HTTP server
const { listen } = createHTTPServer({
  router: appRouter,
  createContext,
});

// Listen on port 2022
listen(2022);
