next-route-map v0.3.1

next-route-map 🚏

next-route-map allows you to define a route map. It automatically generates page modules that forward original modules in build time. Focus on domain, not foldering.

Background

Next.js provides a consistent way to structure and organize pages. It is very intuitive and easy to use. However, when it comes to a larger application with many business domains, the file system based routing can cause several problems.

First, since it is strongly coupled to the file system, a file name can only represent a piece of url path rather than what it actually does. The larger application becomes the file names should be easier to understand. For example, DashboardPage.tsx is much easier to understand than pages/index.tsx. UserSearchPage.tsx is better than pages/users.tsx.

Second, pages/ directory can only contain page modules so you have to place related modules such as components and hooks in other directory. It means that your project will have two directory trees: one starting from pages/ and the other starting from src/. Same domain files are better to be in the same folder. For example, the second one is more organized that the first one.

pages/
  products/
    [id].tsx
products/
  components/
    Thumbnail.tsx

products/
  ProductDetailPage.tsx
  components/
    Thumbnail.tsx

At a glance

With next-route-map you can separate the page modules from routing. It automatically generates page modules from routing file.

Before 🤔

pages/
  index.tsx
  products/
    index.tsx
    [id].tsx
  orders/
    index.tsx
    [id].tsx
products/
  components/
    Thumbnail.tsx
orders/
  hooks/
    usePlaceOrder.ts

After 😊

home/
  HomePage.tsx
products/
  ProductListPage.tsx
  ProductDetailPage.tsx
  components/
    Thumbnail.tsx
orders/
  OrderListPage.tsx
  OrderDetailPage.tsx
  hooks/
    usePlaceOrder.tsx

(auto generated)
pages/
  index.tsx --> home/HomePage.tsx
  products/
    index.tsx --> products/ProductListPage.tsx
    [id].tsx --> products/ProductDetailPage.tsx
  orders/
    index.tsx --> orders/OrderListPage.tsx
    [id].tsx --> orders/OrderDetailPage.tsx

How it works

next-route-map finds all page modules from the project and creates corresponding forwarding modules in the page directory. The forwarding modules look like:

export { default } from '../src/products/ProductDetailPage'

When the page module contains magic functions like getStaticProps or getServerSideProps it will automatically export them as well.

export { default, getServerSideProps } from '../src/products/ProductDetailPage'

Getting started

1. Add routes.config.js file to your project. See the Options for detail API usage.

   module.exports = {
     pagesDir: './pages',
     routes: {
       '/': './src/home/HomePage.tsx',
       '/products': './src/products/ProductListPage.tsx',
       '/products/[id]': './src/products/ProductDetailPage.tsx',
       '/orders': './src/orders/OrderListPage.tsx',
       '/orders/[id]': './src/orders/OrderDetailPage.tsx',
       '/404': './src/errors/404.tsx',
     },
     preservePaths: [
       '_app.tsx',
       '_document.tsx',
     ],
     logger: console,
   }

2. Add next-route-map command to your package.json.

     "scripts": {
   -   "dev": "next dev",
   -   "build": "next build",
   +   "dev": "next-route-map && next dev",
   +   "build": "next-route-map && next build",
       "start": "next start",
       "lint": "next lint"
     },

3. Then the plugin will generate the proper page modules on $ yarn build or $ yarn dev.

   • ./pages/index.ts
   • ./pages/products/index.ts
   • ./pages/products/[id].ts
   • ./pages/orders/index.ts
   • ./pages/orders/[id].ts
   • ./pages/404.ts

   It is safe to add the pages directory to .gitignore.

   /pages/*
   !/pages/_app.tsx
   !/pages/_document.tsx

Options

baseDir

A Next.js project directory. Use this option if your Next.js application is located in somewhere else. Defaults to cwd.

pagesDir

A directory to generate pages. This value may be ./pages or ./src/pages.

routes

A route map for url paths and page file paths.

For example:

{
  '/': './src/home/HomePage.tsx',
  '/products': './src/products/ProductListPage.tsx',
  '/products/[id]': './src/products/ProductDetailPage.tsx',
  '/orders': './src/orders/OrderListPage.tsx',
  '/orders/[id]': './src/orders/OrderDetailPage.tsx',
  '/404': './src/errors/404.tsx',
}

preservePaths

Paths to preserve on clean. Use this option if there is a non-forwarding module in the pages directory. The paths are relative to pages directory.

For example:

['_app.tsx', '_document.tsx']

Note that this option does not guarantee that the path is not ignored from .gitignore. If you makde the pages directory be ignored, you need to explicitly add a rule.

  # next.js
  /pages/*
+ !/pages/_app.tsx
+ !/pages/_document.tsx

logger

If you want log build output, use console.
