Password Autofill on a React Native Expo app

Developing an app to accompany our website, worried that we would lose people in the transition if they couldn't remember their password, we were looking to make our app do Password AutoFill, a feature in iOS.

A talk from WWDC introducing the feature: https://developer.apple.com/videos/play/wwdc2017/206/

It works well, but there were a few bumps in the road making it work for React Native on Expo, so here are some notes to help out.

Apple's docs are here: https://developer.apple.com/documentation/security/password_autofill and they say something like this:

import React from 'react';
import { TaskManager } from 'expo';
import { EventEmitter } from 'fbemitter';

const taskName = 'task-name-of-your-choice';
const taskEventName = 'task-update';
const eventEmitter = new EventEmitter();

TaskManager.defineTask(taskName, ({ data, error }) => {
  if (!error) {

import React, { Component } from 'react'
import { Animated, StyleProp, ViewStyle } from 'react-native'

export type FadeDirection = 'up' | 'down'

interface FadeProps {
  visible?: boolean
  style?: StyleProp<ViewStyle>
  children: React.ReactNode
  direction?: FadeDirection

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)
