Next-ts-routes NPM

Typed Routes

A way to have fully typed routes in next, without all the complexity of tRPC.

This is more for super minimal use cases, where you don't need the full functionality of tRPC.

Installation

npm install next-ts-routes

yarn install next-ts-routes

pnpm install next-ts-routes

Usage

This is an example of how to use next-ts-routes

Add the next wrapper

// next.config.js
const withNextTsRoutes = require('next-ts-routes/withNextTsRoutes')

module.exports = withNextTsRoutes({})

// next.config.mjs
import { env } from "./src/env/server.mjs";
import { withNextTsRoutes } from 'next-ts-routes/withNextTsRoutes';

/**
 * Don't be scared of the generics here.
 * All they do is to give us autocompletion when using this.
 *
 * @template {import('next').NextConfig} T
 * @param {T} config - A generic parameter that flows through to the return type
 * @constraint {{import('next').NextConfig}}
 */
function defineNextConfig(config) {
  return withNextTsRoutes(config);
}

export default defineNextConfig({
});

Set HOST env variables

You have to set HOST or NEXT_PUBLIC_HOST in your environment variables for next-ts-routes to work.

// .env.local
HOST=http://localhost:3000

For the time being this is a hacky way to achieve this, will ideally fine a better way in the future.

// next.config.js
const withNextTsRoutes = require('next-ts-routes/withNextTsRoutes')

module.exports = withNextTsRoutes({}, {
  fs: false
})

Basic Usage

You can see an example with typescript intellisense here - https://stackblitz.com/edit/typescript-qbv1tp?file=index.ts

// api/clip.ts
import { route } from "next-ts-routes";

const { handler, get, post } = route("api/clip", {
  ctx: async () => {
    const Redis = (await import("@upstash/redis")).Redis;

    const redis = new Redis();

    return { redis };
  },
  GET: async ({}, { ctx }) => {
    return ctx.redis.get("clip") as Promise<string | undefined>;
  },
  POST: async ({ input }: { input: { text: string } }, { ctx }) => {
    return ctx.redis.set("clip", input.text);
  },
});

export const getClip = get;
export const postClip = post;

export default handler;

Note: As this file is directly imported in the browser, you cannot use any nodejs specific imports, like fs or path globally. You should dynamically import them and then use them.

Now you can import the getClip and postClip functions and use them in your app.

// pages/index.tsx
import { getClip, postClip } from '../api/clip';

export default function Home() {
  const [clip, setClip] = useState<string | undefined>(undefined);

  useEffect(() => {
    getClip().then(setClip);
  }, []);

  return (
    <div>
      <h1>Clip</h1>
      <p>{clip}</p>
      <form
        onSubmit={async (e) => {
          e.preventDefault();
          const text = e.currentTarget.elements[0].value;
          await postClip({ text });
          setClip(text);
        }}
      >
        <input type="text" />
        <button type="submit">Set</button>
      </form>
    </div>
  );
}

This can totally be used with swr or react-query as well for nice hooks, will write some docs for this later
