React Regex Router

react-regex-router is a very simple router component for React applications which uses regex to determine the component to be rendered

Getting Started

First install the component via npm or yarn:

npm install --save react-regex-router

yarn add react-regex-router

Then import into to your project and set it up like so:

import React, {useState} from 'react';
import Router from 'react-regex-router';
 
// Components you want to render at router
import FirstComponent from './FirstComponent';
import SecondComponent from './SecondComponent';
import ThirdComponent from './ThirdComponent';
 
const App = () => {
  let [currRoute, setRoute] = useState("first");
  // Call setRoute to "first", "second" or "third" anywhere in
  // your application to change the current rendered route
  // You can also use redux or mobX variables instead
 
  return <div className="app">
    <Router
      currRoute={currRoute}
      routes={[
        {
          name: /^First$/i, // The regex to test for
          component: FirstComponent // Component to render
        },
        {
          name: /^Second$/i,
          component: SecondComponent,
          props: { // Pass any props to the rendered component
            id: 2
          }
        },
        {
          name: /^Third/i,
          component: FirstComponent
        }
      ]}
    />
  </div>;
}
 
export default App;

The above code can be used to setup a quick Router instance with your own specified routes

Working

The react-regex-router works by simply taking each "name" in each route of "routes" and testing it against the "currRoute", returning the first matching result.

So for somthing like :-

{
  currRoute: "hello",
  routes: [{
    name: /^hello$/, // /^hello$/i.test("hello") = true
    component: SomeComponent, // this gets rendered
  },{
    name: /^hello/,
    component: SomeOtherComponent
  }]
}

And in the same occurance, if currRoute was changed from "hello" to "hello world", the second component (i.e SomeOtherComponent) would get rendered.

You can also pass props to a component by adding the "props" property to a route :-

{
  currRoute: "hello",
  routes: [{
    name: /^hello$/, // /^hello$/i.test("hello") = true
    component: SomeComponent, // this gets rendered
    props: { // id is passed to SomeComponent
      id: 2
    }
  },{
    name: /^hello/,
    component: SomeOtherComponent
  }]
}

The passed properties are available via a "router" property in the rendered component's props. (By default, the currRoute is also passed)

import React from 'react';
 
const SomeComponent = props => {
  console.log(props.router);
  /*
    prints {
      currRoute: "hello",
      id: 2
    }
  */
 
  return <div></div>;
}
 
export default SomeComponent;

Generally speaking it is recommended to store currRoute in some central state management library like Redux or MobX so it is accessible across your App to change. But it is possible to use the passed properties "setRoute" to change the route if you want to

Router Component

Property	Type	Default	Required	Info
currRoute	string	""	Yes	Used to test against for determining the component to be rendered
routes	array	[]	Yes	Used to pass a list of components and the regexps that will be used to determine which of them to render.

Please Note

As you can probably already tell, this component was meant to be a simple and quick solution for routing components, as such it doesn't much advanced features like changing the browser url (for SEO) etc. For that we recommend using react-router
