Introduction

ElegantRouter is a tool for creating routes based on the file system, which can automatically generate route definitions, route file imports and route-related type definitions. Just create the route file according to the agreed rules, without adding any additional configuration in the route file.

Differences and similarities

The main difference between ElegantRouter and other file system-based routing tools is that:

1. Other tools have complex configuration rules, and the route data is a black box, which is difficult to customize.
2. ElegantRouter follows the api-first principle and automates the process of configuring routes.

Taking configuring react routes as an example, the traditional way of creating page routes requires the following steps:

1. Import the layout component
2. Import the page component
3. Define the route in the route configuration file

Although these steps are not complicated, in actual development, they are repetitive and need to be done manually. In addition, the maintenance of route names and paths is very troublesome, there is no clear agreement on the route definition of the layout and page components, resulting in a messy route definition. And using ElegantRouter, you only need to create the route file according to the agreed rules, you can automatically generate the route in the specified route file.

ElegantRouter's route configuration process

You only need to create a route file according to the agreed rules to generate the route in the specified route file.

Installation

Install the react version (other frameworks to come...)

pnpm install @ohh-889/react-auto-route

Attention item

react-router-dom

• Versions that require installation above 'v6' are not compatible with the lower version of 'react-router-dom'

Lazy loading by route

• Page routing

export function Component() {
  return <div>Component</div>;
}

• Be sure to export with 'export' as the function name 'Component'

If you want to use the default export

1. Override the lazy method

lazy:async ()=>{
 const component=await import('@/views/Component.tsx')

 return {
  Component:component.default
  ErrorBoundary:ErrorBoundary,
 }
//  or you can use the following code
const Component=component.default
return {
  element:<Component />,
  ErrorBoundary:ErrorBoundary,
}
}

• If you use ts, change the ts type declaration

2. Handle route lazy loading by yourself

• Use an 'option' of the route loader

Use

Introduce the plugin in Vite

import { fileURLToPath, URL } from "node:url";
import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import ElegantVueRouter from "@@ohh-889/react-auto-route";

export default defineConfig({
  plugins: [
    react(),
    ElegantreactRouter({
      alias: {
        "@": "src",
      },
      layouts: {
        base: "src/layouts/base-layout/index.tsx",
        blank: "src/layouts/blank-layout/index.tsx",
      },
    }),
  ],
  resolve: {
    alias: {
      "@": fileURLToPath(new URL("./src", import.meta.url)),
    },
  },
});

Integration in react Router

src/router/routes/index.ts

import type { ElegantRoute, CustomRoute } from "@elegant-router/types";
import { generatedRoutes } from "../elegant/routes";
import { layouts, views } from "../elegant/imports";
import { transformElegantRoutesToReactRoutes } from "../elegant/transform";

const customRoutes: CustomRoute[] = [
  {
    name: "root",
    path: "/",
    redirectTo: '/home',
  },
  {
    name: "not-found",
    path: "*",
    component: "$view.404",
  },
];

const elegantRoutes: ElegantRoute[] = [...customRoutes, ...generatedRoutes];

export const routes = transformElegantRoutesToreactRoutes(
  elegantRoutes,
  layouts,
  views
);

src/router/index.ts

import {createBrowserRouter} from 'react-router-dom'
import { routes } from "./routes";

export const router=createBrowserRouter(builtinRoutes)

src/App.tsx

import { RouterProvider } from 'react-router-dom';
import { router } from "@/router";

const App = () => {
  return <RouterProvider router={reactRouter} />
}

Starting the project

After starting the project, the plugin will automatically generate the src/router/elegant directory, and the files in this directory are the automatically generated route import, route definition and route transformation files.

Configuration

Route file creation

You can configure pagePatterns to specify the rules for creating route files. The rules for creating route files are regular expressions, and if the path of a route file matches the regular expression, the route file will be created.

Default: all files named index.tsx、[id].tsx、[module].tsx, etc. below the folder.

pagePatterns: ["**‍/index.tsx", "**‍/[[]*[]].tsx"];

One-level route (single-level route)

Folder structure

views
├── about
│   └── index.tsx

Generated routes

{
  name: 'about',
  path: '/about',
  component: 'layout.base$view.about',
  meta: {
    title: 'about'
  }
},

it is a single level route, to add layout, the component props combines the layout and view component, split by the dollar sign "$"

Transformed react routes

{
  path: '/about',
  component: BaseLayout,
  ErrorBoundary: ErrorBoundary,
  children: [
    {
      id: 'about',
      index:true,
      lazy: () => import('@/pages/about/index.tsx'),
      handle: {
        title: 'about'
      }
    }
  ]
},

Secondary route

Folder structure

views
├── list
│   ├── home
│   │   └── index.tsx
│   ├── detail
│   │   └── index.tsx

Please don't have the following index.tsx on the same level as the folder, this is not part of the agreed upon rules

Error example

views
├── list
│   ├── index.tsx
│   ├── detail
│   │   └── index.tsx

Generated routes

{
  name: 'list',
  path: '/list',
  component: 'layout.base',
  meta: {
    title: 'list'
  },
  children: [
    {
      name: 'list_home',
      path: 'home',
      component: 'view.list_home',
      meta: {
        title: 'list_home'
      }
    },
    {
      name: 'list_detail',
      path: 'detail',
      component: 'view.list_detail',
      meta: {
        title: 'list_detail'
      }
    },
  ]
}

There are two layers of route data for secondary routes, the first layer of route is the layout component and the second layer of route is the page component

Transformed react routes

{
  name: 'list',
  path: '/list',
  component: BaseLayout,
  ErrorBoundary: ErrorBoundary,
  loader: ()=>redirect('/list/home'),
  handle: {
    title: 'list'
  },
  children: [
   {
      name: 'list_home',
      path: 'home',
      lazy: () => import('@/views/list/home/index.tsx'),
      handle: {
        title: 'list_home'
      }
    },
    {
      name: 'list_detail',
      path: 'detail',
      lazy: () => import('@/views/list/detail/index.tsx'),
      handle: {
        title: 'list_detail'
      }
    }
  ]
},

the first layer of route data contains the redirection configuration, which by default redirects to the first sub-route

Multi-level route (level 3 route and above)

Folder structure

• The folder hierarchy is deep

views
├── multi-menu
│   ├── first
│   │   ├── child
│   │   │   └── index.tsx
│   ├── second
│   │   ├── child
│   │   │   ├── home
│   │   │   │   └── index.tsx

• Two-tier folder hierarchy (recommended)

views
├── multi-menu
│   ├── first_child
│   │   └── index.tsx
│   ├── second_child_home
│   │   └── index.tsx

The route hierarchy is split by the underscore symbol "_", which prevents the folder hierarchy from being too deep.

Generated routes

{
  name: 'multi-menu',
  path: '/multi-menu',
  component: 'layout.base',
  meta: {
    title: 'multi-menu'
  },
  children: [
    {
      name: 'multi-menu_first',
      path: 'first',
      meta: {
        title: 'multi-menu_first'
      },
      children: [
        {
          name: 'multi-menu_first_child',
          path: 'child',
          component: 'view.multi-menu_first_child',
          meta: {
            title: 'multi-menu_first_child'
          }
        }
      ]
    },
    {
      name: 'multi-menu_second',
      path: 'second',
      meta: {
        title: 'multi-menu_second'
      },
      children: [
        {
          name: 'multi-menu_second_child',
          path: 'child',
          meta: {
            title: 'multi-menu_second_child'
          },
          children: [
            {
              name: 'multi-menu_second_child_home',
              path: 'home',
              component: 'view.multi-menu_second_child_home',
              meta: {
                title: 'multi-menu_second_child_home'
              }
            }
          ]
        }
      ]
    }
  ]
}

if the route level is greater than 2, the generated route data is a recursive structure

Transformed react routes

{
  name: 'multi-menu',
  path: '/multi-menu',
  component: BaseLayout,
  redirect: {
    name: 'multi-menu_first'
  },
  meta: {
    title: 'multi-menu'
  },
  children: [
    {
      name: 'multi-menu_first',
      path: 'first',
      loader:()=>redirect('child')},
      handle: {
        title: 'multi-menu_first'
      },
      children: [
     {
      name: 'multi-menu_first_child',
      path: 'child',
      lazy: () => import('@/views/multi-menu/first_child/index.tsx'),
      handle: {
        title: 'multi-menu_first_child'
      }
    },
      ]
    },
    {
      name: 'multi-menu_second',
      path: 'second',
      loader:()=>redirect('child'),
      handle: {
        title: 'multi-menu_second'
      },
      children:[
        {
      name: 'multi-menu_second_child',
      path: 'child',
      loader:()=>redirect('home'),
      handle: {
        title: 'multi-menu_second_child'
      },
      children:[
      {
      name: 'multi-menu_second_child_home',
      path: 'home', 
      lazy: () => import('@/views/multi-menu/second_child_home/index.tsx'),
      handle: {
        title: 'multi-menu_second_child_home'
      }
      }
      ]
    },
      ]
    },
    
    
  ]
},

Accessmeta

import { useMatches } from "react-router-dom";

const matches = useMatches();
const meta= matches[matches.length - 1].handle;

the transformed react routes only has two levels, the first level is the layout component, and the second level is the redirect routes or the page routes

Ignore folder aggregation routes

Folder names that begin with an underscore "_" will be ignored

Folder structure

views
├── _error
│   ├── 403
│   │   └── index.tsx
│   ├── 404
│   │   └── index.tsx
│   ├── 500
│   │   └── index.tsx

Generated routes

{
  name: '403',
  path: '/403',
  component: 'layout.base$view.403',
  meta: {
    title: '403'
  }
},
{
  name: '404',
  path: '/404',
  component: 'layout.base$view.404',
  meta: {
    title: '404'
  }
},
{
  name: '500',
  path: '/500',
  component: 'layout.base$view.500',
  meta: {
    title: '500'
  }
},

Parameter Route

Folder structure

views
├── user
│   └── [id].tsx

Generated routes

{
  name: 'user',
  path: '/user/:id',
  component: 'layout.base$view.user',
  props: true,
  meta: {
    title: 'user'
  }
}

Advanced parameter route

import type { RouteKey } from "@elegant-router/types";

ElegantreactRouter({
  routePathTransformer(routeName, routePath) {
    const routeKey = routeName as RouteKey;

    if (routeKey === "user") {
      return "/user/:id(\\d+)";
    }

    return routePath;
  },
});

Custom Route

the custom route is only used to generate the route declaration, and the route file is not generated, you should create the route file manually.

Config custom routes

ElegantreactRouter({
  customRoutes: {
    map: {
      root: "/",
      notFound: "*",
    },
    names: ["two-level_route"],
  },
});

Generated CustomRouteKey

type RouteMap = {
  root: "/";
  notFound: "*";
  "two-level": "/two-level";
  "two-level_route": "route";
};

type CustomRouteKey = "root" | "notFound" | "two-level" | "two-level_route";

Custom routes's component

it can use existing page components as the route component

import type { CustomRoute } from "@elegant-router/types";

const customRoutes: CustomRoute[] = [
  {
    name: "root",
    path: "/",
    redirectTo: {
      name: "403",
    },
  },
  {
    name: "not-found",
    path: "*",
    component: "layout.base$view.404",
  },
  {
    name: "two-level",
    path: "/two-level",
    component: "layout.base",
    children: [
      {
        name: "two-level_route",
        path: "/two-level/route",
        component: "view.about",
      },
    ],
  },
];

Plugin Option

ElegantRouterOption:

ElegantreactRouterOption:

extends ElegantRouterOption

Caveat

• Folder naming: can only contain letters, numbers, dash, underscore, and no other special characters

  The underscore is a cut identifier for the routing hierarchy, and the short horizontal line is used to connect multiple words in a one-level route
