react-intl - accessing nested messages

Question

I\'m trying to use react-intl package inside an app. The app is rendered on the server so I wrote some code to determine which language to use and serve into

Answer 1

Since React Intl v2 no longer supports nested messages objects, the messages need to be flattening.

export const flattenMessages = ((nestedMessages, prefix = '') => {
  if (nestedMessages === null) {
    return {}
  }
  return Object.keys(nestedMessages).reduce((messages, key) => {
    const value       = nestedMessages[key]
    const prefixedKey = prefix ? `${prefix}.${key}` : key

    if (typeof value === 'string') {
      Object.assign(messages, { [prefixedKey]: value })
    } else {
      Object.assign(messages, flattenMessages(value, prefixedKey))
    }

    return messages
  }, {})
})

// Use flattenMessages
