react-autocomplete-email

A configurable & lightweight React wrapper component that enables "out of the box" email autocomplete/suggestions on input elements.

✅ A wrapper component so you can use alongside other form enabled libraries (such as Buefy).
✅ Customizable.
✅ Allow users to easily navigate the suggestions list by simply using the "up/down" keys.
✅ Users can also auto-fill the input with the desired value by hitting the "enter" key upon selection.

Check out the Vue.js version here.

    "domain3.com",
    "domain4.com",

  ]

  return (

    <EmailAutoComplete ref={emailAutoCompleteRef} onCompletion={val => setInputVal(val)} domains={customDomains}>
      <input type="text" name="email" placeholder="Email..." value={inputVal} onChange={(e) => {setInputVal(e.target.value); emailAutoCompleteRef.current.change(e)}} onKeyDown={(e) => emailAutoCompleteRef.current.check(e)} />
    </EmailAutoComplete>
    
  );

}

export default App;

Configuration Example (On Submit Callbacks)

function App() {

  /* Set state and ref */

  const [inputVal, setInputVal] = useState('')
  const emailAutoCompleteRef = useRef();
  
  const validateForm = () => {
    
    /* Called when a user hits enter when focused on the wrapped input element */
    
  };

  return (
      
    <EmailAutoComplete ref={emailAutoCompleteRef} onCompletion={val => setInputVal(val)} onSubmit={() => validateForm()}>
      <input type="text" value={inputVal} onChange={(e) => {setInputVal(e.target.value); emailAutoCompleteRef.current.change(e)}} onKeyDown={(e) => emailAutoCompleteRef.current.check(e)} />
    </EmailAutoComplete>
    
  );

}

export default App;

Configuration Example (Custom Inline Styles)


/* A "css" prop is added to the component and references a computed property below */


/* Import useState and useRef from React and import package */

import React, { useState, useRef } from 'react';
import EmailAutoComplete from 'react-autocomplete-email';

function App() {

  /* Set state and ref */

  const [inputVal, setInputVal] = useState('')
  const emailAutoCompleteRef = useRef();
  
  const styleOverrides = {
  
    /* Edit style for the suggestions "outer" container */

    container: {
      position: 'fixed',
      top: '40px',
      left: '40px'
    },

    overlay: {
      backgroundColor: #FFF
    },

    /* Edit style for the suggestions text */

    text: {

      /* Main text */

      },

      /* Highlighted/matched text */

      highlight: {
        color: blue
      }
  };

  return (
      
    <EmailAutoComplete ref={emailAutoCompleteRef} onCompletion={val => setInputVal(val)} css={styleOverrides}>
      <input type="text" value={inputVal} onChange={(e) => {setInputVal(e.target.value); emailAutoCompleteRef.current.change(e)}} onKeyDown={(e) => emailAutoCompleteRef.current.check(e)} />
    </EmailAutoComplete>
    
  );

Props

Prop	Type	Optional	Default	Description
domains	Array	No	A selection of the most statistically popular email domain extensions.	A customized list of email domain extensions.
onCompletion	Function	Yes	N/A	A function that you'd like the component to invoke after the user has selected a suggested completion (e.g. update the value/model of the input element).
onSubmit	Function	No	N/A	A function that you'd like the component to invoke once the user hits the "enter" key when the nested input is in focus (e.g. carry out validations or submit the form).
css	Object	No	N/A	CSS style overrides for specific elements of the suggestions component (See above examples).

:racing_car: Roadmap

Add extra CSS override mappings.
Add ability to override CSS with a stylesheet (enables usage with media queries).
Autocomplete default suggestions list to be based on browser language detection, which will make the suggestions more regionally relevant.
