About

routes-gen is a framework agnostic CLI tool for routes parsing and generation of a type-safe helper for safe route usage. Think of it as Prisma, but for routes.

Installation

First, you have to install the routes generator itself:

yarn add routes-gen

Official Drivers

The generator works with "drivers", which are route parsers for different frameworks.

Usage Example

You can simply run:

yarn routes-gen -d @routes-gen/remix

It will parse and export the routes, based on the driver that you've provided.

For example, the @routes-gen/remix driver will export the routes by default to /app/routes.d.ts.

Note that you can change the output path via the --output or -o flag.

Now you can import the generated route helper anywhere and enjoy the typings:

import { route } from "routes-gen";

// Compiles to /products
route("/products");

// Compiles to /products/1337
route("/products/:productId", {
    productId: "1337",
});

Params Types Usage

You can use the RouteParams type to add typings to your dynamic route parameters/segments. Example:

import { RouteParams } from "routes-gen";

const { productId } = params as RouteParams["/products/:productId"];

Remix example:

import { LoaderFunction, useParams } from "remix";
import { RouteParams } from "routes-gen";

export const loader: LoaderFunction = async ({ params }) => {
  const { productId } = params as RouteParams["/products/:productId"];
};

export default function Product() {
  const { productId } = useParams<RouteParams["/products/:productId"]>();

  return <div />;
}

CLI Options

Writing Your Driver

If there is no driver for your preferred framework, you can write your own. For example, create a simple driver.js file in your project, with the following content:

module.exports = {
    // Where to export the typings if the "output" flag was not provided.
    defaultOutputPath: "src/routes.d.ts",
    
    // The routes parser. Must export and array of routes matching the { path: string } interface.
    routes: async () => {
        return [
            {
                path: "/products",
            },
            {
                path: "/products/:productId", // Note that the dynamic segments must match the :myVar pattern.
            },
        ];
    },

    // The paths to be watched for changes. Must return and array of relative paths.
    watchPaths: async () => {
        return ["/my-routes/**/*.{ts,tsx,js,jsx}"];
    },
}

Now you can easily use it:

routes-gen -d driver.js

You can also publish it to npm, install it, and use it as a package:

routes-gen -d my-driver-package

Please consider submitting your drivers to this repository.
