Stage 10: Basic Routing

1. Add basic routing to render navigate between a new component and the existing wallet component

Video Tutorial

• Change into the wallet-template directory

  cd ~/Desktop/blg/wallet-template

• Add the react-router-dom package to the project

  npm install --save react-router-dom@4.3.1

• Example output:

  wallet-template$ npm install --save react-router-dom@4.3.1
  [..]
  + react-router-dom@4.3.1
  updated 1 package and audited 13712 packages in 9.686s
  found 40 vulnerabilities (31 low, 6 moderate, 3 high)
  run `npm audit fix` to fix them, or `npm audit` for details
  wallet-template$

• Import the router components into the app, within App.js at line 2

  import { BrowserRouter, Route, Link } from 'react-router-dom';

• Wrap the existing {component} in App.js at line 150 with the router, ~line 150 & line 152

  <BrowserRouter>
    <div> 
      {component}
    </div> 
  </BrowserRouter>

Important

The two routes below must go within the <div> with the <BrowserRouter>.

i.e.

<BrowserRouter>
  <div>
    <Route exact={true} path="/" render={() => component}/>
    <Route exact={true} path="/newPage" render={() => <h1>New Page!</h1>} />
  </div>
</BrowserRouter>

• Add a route for the default page, replace the existing {component} line 151 with the route below on line 151

  <Route exact={true} path="/" render={() => component}/>

• Add a secondary route for the new page you are going to create, line 152

  <Route exact={true} path="/newPage" render={() => <h1>New Page!</h1>} />

Note

Give the new route a try! Directly in the browser in the search bar add the path newPage to the url resulting in: http://localhost:3000/newPage

• Add a button to navigate to the new page from the wallet, add this link at the top of your component, ~line 110-112

  <Link to={'newPage'}>
    <RaisedButton label=">>> New Page" secondary={true} fullWidth={true}/>
  </Link>

  • It should result in the following:

    component = <div>
      <Link to={'newPage'}>
        <RaisedButton label=">>> New Page" secondary={true} fullWidth={true}/>
      </Link>
      <h3>Active Account</h3>
      [...]

• Confirm selection of the new button will change the route in the url to /newPage

2. Create your new page!

• Add a basic component with a link back to the wallet to begin with, add this component beneath the existing component just before the return state, line 147-151

  const newPage = <div>
    <Link to={'/'}>
      <RaisedButton label="Wallet <<<" primary={true} fullWidth={true}/>
    </Link>
  </div>

• Update your newPage route to now render this component, line 162

  <Route exact={true} path="/newPage" render={() => newPage} />
