API

React-Static is packed with awesome components, hooks, and functions to help you be productive. Exports located in the react-static package are meant to be used in the browser context, in your application code and in browser.api.js. Exports located in the react-static/node package are meant to be used in the node context like static.config.js and node.api.js)

react-static
react-static/node

`react-static`

The following functions are available via the react-static import. They are primarily for use in the browser environment, but are also available for use in browser.api.js plugin files, too.

`Routes`

React Static handles all of your routing for you using react-router under the hood. All you need to do is import Routes and specify where you want to render them:

// App.js
import { Root, Routes } from 'react-static'

export default () => (
  <Root>
    <Routes />
  </Root>
)

The routes that will be rendered are the routes returned by the getRoutes function of this config.

Custom `Routes` Rendering

Occasionally, you may need to render the automatic <Routes> component in a custom way. The most common use-case is for rendering animated routes, described further in the animated-routes guide. To do this, utilize a render prop:

import React from 'react'
import { Root, Routes } from 'react-static'

export default () => (
  <Root>
    <Routes
      render={({ routePath, getComponentForPath }) => {
        // The routePath is used to retrieve the component for that path
        const element = getComponentForPath(routePath)
        return element
      }}
    />
  </Root>
)

Render Props - These special props are sent to your render function:

getComponentForPath(pathname) => ReactElement - Takes a pathname and returns an element (if a route exists) to render that path. Returns false if no route is found.
routePath: String - The path of the current route. You can pass it to getComponentForPath.

`useRouteData`

Via suspense, the useRouteData hook asynchronously provides the results of a routes's getData function as defined in your static.config.js. If you are unable to use a hook in your component, you may also use the RouteData component or withRouteData HOC to access routeData, though we suggest refactoring to hooks for future releases.

static.config.js

module.exports = {
  getRoutes: () => [
    {
      path: '/top-100-songs',
      getData: async () => ({
        songs: await SpotifyAPI.getTopSongs(100),
      }),
    },
  ],
}

TopSongs.js

import { useRouteData } from 'react-static'

export default () => {
  const { songs } = useRouteData()
  return (
    <div>
      <h1>Top 100 Spotify Songs</h1>
      <ul>
        {songs.map(song => (
          <li key={song.id}>{song.title}</li>
        ))}
      </ul>
    </div>
  )
}

`useSiteData`

Via suspense, the useSiteData hook asynchronously provides the results of the getSiteData function as defined in your static.config.js.

If you are unable to use a hook in your component, you may also use the SiteData component or withSiteData HOC to access siteData, though we suggest refactoring to hooks for future releases.

static.config.js

module.exports = {
  getSiteData: () => ({
    siteTitle: 'React Static',
    metaDescription: 'A progressive static-site framework for React',
  }),
}

Home.js

import { useSiteData } from 'react-static'

export default () => {
  const { siteTitle, metaDescription } = useSiteData()

  return (
    <div>
      Welcome to {siteTitle}! {metaDescription}
    </div>
  )
}

Note: Make sure to wrap components using useSiteData() with React's <Suspense fallback="..."></Suspense>. More information on the subject is available here.

`Head`

Head is a react component for managing tags in the document's head. Use it to update meta tags, title tags, etc.

It can be used anywhere in your app.
It can be used in multiple places at the same time.
For more information, see the React-Helmet library that React Static uses to accomplish this.

Example

import { Head } from 'react-static'

export () => (
  <div>
    <Head>
      <meta charSet="UTF-8" />
      <title>This is my page title!</title>
    </Head>
    <div>
      My page content...
    </div>
  </div>
)

`usePrefetch`

The usePrefetch hook binds the prefetching of a specific path's assets to the visibility of an element. When the ref's element becomes visible in the viewport, the template and data required to render the route for the path will be prefetched.

This increases the chance that if the user then navigates to that route, they will not have to wait for the required data to load.

import { useRef } from 'react'
import { usePrefetch } from 'react-static'

export default () => {
  // Use it to create a ref
  const myRef = usePrefetch('/blog')

  // or pass your own ref
  const myRef = useRef()
  usePrefetch('./blog', myRef)

  return (
    <Link to="/blog" ref={myRef}>
      Go to blog
    </Link>
  )
}

Note: It's critical that the ref.current value passed to usePrefetch resolves to an actual dom element. Otherwise an error will be thrown.

`prefetch`

prefetch is an imperative version of the usePrefetch hook that you can use anywhere in your code.

Example:

import { prefetch } from 'react-static'

const myFunc = async () => {
  const data = await prefetch('/blog')
  console.log('The preloaded data:', data)
}

`addPrefetchExcludes`

addPrefetchExcludes allows you to register dynamic route exclusions at runtime, so as to not produce 404 errors when attempting to preload static data / templates that link to these routes.

Arguments
- excludes: Array[string | RegExp] - An array of strings and/or RegExp objects
  - string - Any routes starting with this string will be excluded
  - RegExp - Any routes matching this regular expression will be excluded
Returns nothing

Example:

import { addPrefetchExcludes } from 'react-static'

// Run this before your app code
addPrefetchExcludes(['dynamic', /admin/i])

// Your app code
// ...

`react-static/node`

The following functions are available as exports from the react-static/node module. They are a separate import so that they may be used primarily in your static.config.js and node.api.js plugin files.

`rebuildRoutes`

Intended for use in your static.config.js during development. When called it will rebuild all of your routes and routeData by calling config.getRoutes() again. Any new routes or data returned will be hot-reloaded into your running development application. Its main use cases are very applicable if your routes or routeData are changing constantly during development and you do not want to restart the dev server. You can use this method to reload when local files are changed, update at a set timing interval, or even subscribe to an event stream from an API or CMS.

Arguments
- paths: Array - The paths to reload (defaults to all).
Returns a Promise

Example:

// static.config.js
import { rebuildRoutes } from 'react-static/node'

// Reload Manually
rebuildRoutes()

// Reload when files change
import chokidar from 'chokidar'
// Ensure routes are built at least once before rebuilding routes
let areRoutesBuilt = false
chokidar.watch('./docs').on('all', () => isReady && rebuildRoutes())

// Reload from API or CMS event
YourFavoriteCMS.subscribe(rebuildRoutes)

// Reload your routes every 10 seconds
setInterval(rebuildRoutes, 10 * 1000)

// ETC!

export default {
  getRoutes: () => {
    areRoutesBuilt = true
    // This will run each time `rebuildRoutes` is called
  },
}

`makePageRoutes`

A utility function to aid in splitting an array of items into separate pages for use in your static.config.js

Arguments
- options{} - Required
  - items: Array - Required - The array of items to split into pages
  - pageSize: Int - Required - The number of items on each page
  - route{}: Object - Required
    - path: String - Required - The base path that all pages will share
    - template: String - The base component that all pages will share
  - decorate: Function - Required
    - Arguments:
      - items: Array - The items for the given page
      - pageIndex: Int - The page index for the given page
      - totalPages: Int - The total number of pages that were generated
    - Returns an Object that will decorate the base route. In most cases, this will probably include the getData and children keys, but can contain any route supported keys
  - pageToken: String - The string that will be used to prefix each page.
Returns an array of routes objects

Example:

// static.config.js
import { makePageRoutes } from 'react-static/node'

export default {
  getRoutes: () => {
    const posts = [...]

    return [
      ...makePageRoutes({
        items: posts, // Use the posts array as items
        pageSize: 5, // Use 5 items per page
        pageToken: 'page', // use page for the prefix, eg. blog/page/3
        route: {
          // Use this route as the base route
          path: 'blog',
          template: 'src/containers/Blog',
        },
        decorate: (items, pageIndex, totalPages) => ({
          // For each page, supply the posts, page and totalPages
          getData: () => ({
            posts: items,
            currentPage: pageIndex,
            totalPages,
          }),
          // Make the routes for each blog post
          children: items.map(post => ({
            path: `/blog/post/${post.id}`,
            template: 'src/containers/Post',
            getData: () => ({
              post,
            }),
          })),
        }),
      }),
    ]
  }
}

`createSharedData`

Each route's getData function results in a separate data file for each route being stored as JSON next to the routes HTML on export. This covers the 90% use case for data splitting, but if you want even more control and want to optimize repeated data across routes, you can use this function to create shared data fragments for use in your routes.

These shared data fragments can be placed in any route's sharedData object. At runtime, the shared data will only be requested once per session and automatically merged into the route data, which you can consume normally through the RouteData or withRouteData component/HOC pair.

Example

Consider a large and heavy menu structure that is present only on the blog portion of your site. In this case, the menu data should only be loaded on the pages that use it, and only once per session (cached), instead of on every page individually. First we would use the createSharedData function and pass the data we want to share between our routes. Then in each route, we can pass the result of our createSharedData call as a prop to the route's sharedData property. The shared data props will then be stored, served and cached only once per session and merged into the result of the routes getData result at runtime!

// static.config.js
import { createSharedData } from 'react-static/node'

export default {
  getRoutes: async () => {
    const blogMenu = createSharedData(getMyLargeAndHeavyMenu())
    return [
      {
        path: '/',
        template: 'src/containers/Home',
      },
      {
        path: '/blog',
        template: 'src/containers/Docs',
        sharedData: {
          blogMenu, // `blogMenu` will now be available to this route via
          // RouteData but will only be loaded once per session!
        },
      },
      {
        path: '/help',
        template: 'src/containers/Help',
        sharedData: {
          blogMenu, // `blogMenu` will now be available to this route via
          // RouteData but will only be loaded once per session!
        },
      },
    ]
  },
}
