Pronunciation

"Woonerf" is a Dutch word for a small neighborhood street where vehicles must move very slowly. The kind of road you can imagine allowing kids to play in. Although it's fun to pronounce it as "woo nerf", the break is after the n (woon == living, erf == yard). A good transliteration for an American English speaker would be "Vone Airf".

Usage

Let's create a Redux application:

const mount = require('@conveyal/woonerf/mount')

const Application = require('./containers/application')
const reducers = require('./reducers')

mount({
  app: Application,
  id: 'root',
  reducers
})

This will create a redux store with the fetch, history, logger, multi, and promise middleware applied, wrap your application with a redux provider, initialize the browser history, and mount your component to #id.

API

auth0

Login Component

Create a simple login component with custom Auth0-lock options.

import Auth0 from '@conveyal/woonerf/components/auth0-lock'

export default function Login () {
  const lockOptions = {}
  return (
    <Auth0
      lockOptions={lockOptions}
      />
  )
}

Authentication helpers

refreshUser

Refresh a user. To be used within a redux connected component. Will send update actions to a redux store based on response from Auth0.

import {refreshUser} from '@conveyal/woonerf/auth0'

...

function mapDispatchToProps (dispatch) {
  return {
    refreshUserToken: () => refreshUser(dispatch)
  }
}

...

fetch

fetch({url, options, next, retry})

Create a fetch action to be dispatched by the store. Key features:

• Automatically JSON.stringify bodies that are objects and automatically JSON.parse responses that are application/json.
• next is a function that's result will be dispatched by the store. It can be an async function.
• retry is a function that receives the response and needs to resolve to a Boolean. It can be an async function.

const fetch = require('@conveyal/woonerf/fetch')

store.dispatch(fetch({
  url: 'http://conveyal.com',
  options: {
    method: 'post',
    body: {hello: 'world'}
  },
  retry: async (response) => {
    if (response.status !== 200) {
      await timeout(2000)
      return true
    } else {
      return false
    }
  },
  next: async (error, response) => {
    return actionBasedOn(response)
  }
}))

fetchMultiple

fetchMultiple({fetches, next})

Allows you to dispatch a single action that will call next with all of the responses.

const {fetchMultiple} = require('@conveyal/woonerf/fetch')

store.dispatch(fetchMultiple({
  fetches: [{
    url: 'http://conveyal.com',
    options: {
      body: {hello: 'world'}
    }
  }],
  next: async (error, responses) => {
    return actionBasedOn(response)
  }
}))

html

html({title})

mount

mount({app, id, reducers})
