Requirements

This package has the following peer dependencies:

• React v16.8.0+ (for hooks ⚓️)

• React Router DOM v5.0.0+

Installation

With npm:

$ npm install react-router-guards

With yarn:

$ yarn add react-router-guards

Then with a module bundler like webpack, use as you would anything else:

// using ES6 modules
import { GuardProvider, GuardedRoute } from 'react-router-guards';

// using CommonJS modules
const GuardProvider = require('react-router-guards').GuardProvider;
const GuardedRoute = require('react-router-guards').GuardedRoute;

Basic usage

Here is a very basic example of how to use React Router Guards.

import React from 'react';
import { BrowserRouter } from 'react-router-dom';
import { GuardProvider, GuardedRoute } from 'react-router-guards';
import { About, Home, Loading, Login, NotFound } from 'pages';
import { getIsLoggedIn } from 'utils';

const requireLogin = (to, from, next) => {
  if (to.meta.auth) {
    if (getIsLoggedIn()) {
      next();
    }
    next.redirect('/login');
  } else {
    next();
  }
};

const App = () => (
  <BrowserRouter>
    <GuardProvider guards={[requireLogin]} loading={Loading} error={NotFound}>
      <Switch>
        <GuardedRoute path="/login" exact component={Login} />
        <GuardedRoute path="/" exact component={Home} meta={{ auth: true }} />
        <GuardedRoute path="/about" exact component={About} meta={{ auth: true }} />
        <GuardedRoute path="*" component={NotFound} />
      </Switch>
    </GuardProvider>
  </BrowserRouter>
);

Concepts

Navigation lifecycle

With the addition of guard middleware, the navigation lifecycle has changed.

Guard functions

Guard functions are the middleware between navigation and rendering.

Page components

Page components are used for setting loading and error pages.

Guard Provider

The GuardProvider component is a high-level wrapper for your entire routing solution.

Guarded Route

The GuardedRoute component acts as a replacement for the default Route component provided by React Router, allowing for routes to use guard middleware.

Demos

We've included some demos below to help provide more context on how to use this package!

Basic
