ink-router

An implementation of react-router for ink.

Installation

Using yarn:

$ yarn add ink-router

Usage

As much as possible, this project aims to match the behaviour of react-router.

It exposes the following components (and higher-order component):

import {
  Router,
  CommandLineRouter,
  Route,
  Switch,
  withRouter
} from 'ink-router'

<Router />

Wraps your command-line application with a router context:

import { h, render } from 'ink'
import { Router } from 'ink-router'

render(
  <Router>
    <App />
  </Router>
)

Accepts the following props:

PropDescriptionDefault
initialEntriesAn array of URLs to populate the router history with['/']
initialIndexThe initial index in initialEntries at which navigation should begin0
keyLengthThe length of key to generate to uniquely identify each route6
childrenA single child element to renderrequired
getUserConfirmationA function to use to confirm navigation.NOTE: There is no <Prompt /> component yet, and as such no need for getUserConfirmation.none

<CommandLineRouter />

Provides an instance of Router, with its initial route set based on the arguments passed to the current process. In other words, it translates command-line arguments to a path that your application can use for routing, and other decisions.

Command-line arguments are parsed using yargs-parser.

It accepts the same props as Router, with the following changes:

PropDescriptionDefault
argsAn array of arguments to parse and use as the initial routeprocess.argv.slice(2)
optionsAn optional object of options to pass to yargs-parsernone
initialEntriesAn array of history entries to prepend to the initially derived route[]
initialIndexAs per RouterinitialEntries.length

<Route />

Just like in react-router, this allows you to control the rendering of a component, based on whether the specified path matches the current router location.

import { h, render } from 'ink'
import { Router } from 'ink-router'
import { HomeView, SettingsView } from './views'

render(
  <Router>
    <div>
      <Route exact path="/" component={HomeView} />
      <Route path="/settings" component={SettingsView} />
    </div>
  </Router>
)

Accepts the following props:

PropDescriptionDefault
pathThe path on which to match. Supports named parameters, as per path-to-regexp'/'
exactIf true, the component will only render if the path matches exactly.false
componentThe component to render if the path matchesrequired

NOTE: While react-router's Route component accepts 3 different ways to render an element, ink-router only supports one: the component prop.

The rendered component will be passed the following properties:

// Assuming the following route matched
<Route path="/settings/:settingsView" component={SettingsView} />

// SettingsView will receive these props
{
  match: {
    path: '/settings/accounts', // The exact path matched
    params: {
      settingsView: 'accounts'
    }
  },
  location: { ... }, // An object containing the current location from history
  history: { ... }, // The history object from the router
}

<Switch />

When given a set of <Route /> as children, this component will only render the first that matches the current location.

import { h, render } from 'ink'
import { CommandLineRouter, Switch, Route } from 'ink-router'
import { HomeView, SettingsView } from './views'

render(
  <CommandLineRouter>
    <Switch>
      <Route exact path="/" component={HomeView} />
      <Route path="/settings" component={SettingsView} />
    </Switch>
  </CommandLineRouter>
)

Providing a fallback route

In the above example, when the user supplies arguments of not a route to the command, the default fallback message is shown, providing information about the route supplied.

Demo of Switch component

You can override this message by providing a catch-all route as the last child of your <Switch />:

import { h, render } from 'ink'
import { CommandLineRouter, Switch, Route } from 'ink-router'
import { HomeView, SettingsView, NotFoundView } from './views'

render(
  <CommandLineRouter>
    <Switch>
      <Route exact path="/" component={HomeView} />
      <Route path="/settings" component={SettingsView} />
      <Route path="/" component={NotFoundView} />
    </Switch>
  </CommandLineRouter>
)

Alternatively, you can pass the component to render as the notFound prop of your <Switch />, although support for this may be removed in future:

import { h, render } from 'ink'
import { CommandLineRouter, Switch, Route } from 'ink-router'
import { HomeView, SettingsView, NotFoundView } from './views'

render(
  <CommandLineRouter>
    <Switch notFound={NotFoundView}>
      <Route exact path="/" component={HomeView} />
      <Route path="/settings" component={SettingsView} />
    </Switch>
  </CommandLineRouter>
)

withRouter(WrappedComponent)

A higher-order component that empowers a child component with router powers.

Here's an example of a component that redirects after a few seconds:

import { h, Component, Text } from 'ink'
import { withRouter } from 'ink-router'
import PropTypes from 'prop-types'

class RedirectAfterTime extends Component {
  static propTypes = {
    delay: PropTypes.number
    to: PropTypes.string.isRequired,
    history: PropTypes.shape({
      replace: PropTypes.func
    })
  }
  static defaultProps = {
    delay: 3000
  }
  componentDidMount() {
    this.timeout = setTimeout(this.redirect, this.props.delay)
  }
  componentWillUnmount() {
    clearTimeout(this.timeout)
  }
  redirect = () => {
    this.props.history.replace(this.props.to)
  }
  render() {
    return <Text italic>Redirecting shortly...</Text>
  }
}

export default withRouter(RedirectAfterTime)
