React Email Autocomplete is an unstyled, zero-dependency component inspired by some european flight booking websites. As soon as users start typing their email address, it will suggest the most common email providers.
- Completely unstyled and white labeled (ships with zero CSS)
- Fully accessible with superlative keyboard controls
- Forward any event and attribute to the
<input />
element or control it with React Hook Form
Demo and examples — Stackblitz — NextJS
:floppy_disk: Installation
pnpm add @smastrom/react-email-autocomplete
# npm i @smastrom/react-email-autocomplete
# yarn add @smastrom/react-email-autocomplete
:art: Usage / Styling
The component renders a single div
with a very simple structure:
Wrapper — div
├── Email Input Field — input
└── Dropdown — ul
└── Suggestions - li[]
└──[username - span:first-of-type] [@domain.com - span:last-of-type]
Specify classNames
for each element you'd like to style:
import { Email } from '@smastrom/react-email-autocomplete'
const classNames = {
wrapper: 'my-wrapper',
input: 'my-input',
dropdown: 'my-dropdown',
suggestion: 'my-suggestion',
username: 'my-username',
domain: 'my-domain',
}
const baseList = ['gmail.com', 'yahoo.com', 'hotmail.com', 'aol.com', 'msn.com']
function App() {
const [email, setEmail] = useState('')
return (
<Email
classNames={classNames}
baseList={baseList}
onChange={setEmail} // or (newValue) => customSetter(newValue)
value={email}
/>
)
}
components/Email.tsx
'use client'
import { useState } from 'react'
import { Email as EmailAutocomplete } from '@smastrom/react-email-autocomplete'
const classNames = {
wrapper: 'my-wrapper',
input: 'my-input',
dropdown: 'my-dropdown',
suggestion: 'my-suggestion',
username: 'my-username',
domain: 'my-domain',
}
const baseList = ['gmail.com', 'yahoo.com', 'hotmail.com', 'aol.com', 'msn.com']
export function Email() {
const [email, setEmail] = useState('')
return (
<EmailAutocomplete
classNames={classNames}
baseList={baseList}
onChange={setEmail} // or (newValue) => customSetter(newValue)
value={email}
/>
)
}
app/page.tsx
import { Email } from '@/components/Email'
export default function Home() {
return (
<main>
{/* ... */}
<Email />
{/* ... */}
</main>
)
}
import type { ClassNames } from '@smastrom/react-email-autocomplete'
const myClassNames: ClassNames = {
wrapper: 'my-wrapper',
input: 'my-input',
}
You can add a this property in VSCode's settings.json
in order to enable autcomplete for any object property or variable ending with ClassNames
.
"tailwindCSS.experimental.classRegex": [
["ClassNames \\=([^;]*);", "'([^']*)'"],
["ClassNames \\=([^;]*);", "\"([^\"]*)\""],
["ClassNames \\=([^;]*);", "\\`([^\\`]*)\\`"]
],
This package ships with zero css. Initial styles enough to see the component in action may match the following properties:
.my-wrapper,
.my-input {
position: relative;
}
.my-input,
.my-dropdown,
.my-suggestion {
font-size: inherit;
box-sizing: border-box;
width: 100%;
}
.my-dropdown {
position: absolute;
margin: 0.45rem 0 0 0;
padding: 0;
list-style-type: none;
z-index: 999;
}
.my-suggestion {
cursor: pointer;
user-select: none;
overflow: hidden;
}
Focus/Hover styles
Although you can target the pseudo classes :hover
and :focus
, it is recommended instead to target the attribute data-active-email
in order to avoid :hover
styles to be applied to a suggestion as soon as the dropdown is opened (in case the cursor is hovering it).
.my-suggestion[data-active-email='true'] {
background-color: aliceblue;
}
.my-suggestion:hover,
.my-suggestion:focus,
.my-suggestion:focus-visible {
outline: none;
}
The attribute name can also be customized via activeDataAttr
prop:
<Email
activeDataAttr="data-custom-attr"
classNames={{
...classNames,
suggestion: 'my-suggestion',
}}
baseList={baseList}
value={email}
/>
.my-suggestion[data-custom-attr='true'] {
background-color: aliceblue;
}
:dna: Modes
1. Basic Mode
Once users start typing, it displays a list of base suggestions and hides it once they type @
. It already gives a nice UX and should be enough for the vast majority of websites:
| Before typing @
| After typing @
|
| ------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------- |
| | |
import { Email } from '@smastrom/react-email-autocomplete'
const baseList = [
'gmail.com',
'yahoo.com',
'hotmail.com',
'aol.com',
'msn.com',
'proton.me',
]
function App() {
const [email, setEmail] = useState('')
return (
<Email
baseList={baseList}
onChange={setEmail} // or (newValue) => customSetter(newValue)
value={email}
/>
)
}
2. Refine Mode (optional)
Acts like Basic Mode until users type @
. Then as they start typing the domain, it starts refining suggestions according to an extended list of domains.
| Before typing @
| After typing @
|
| ------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------- |
| | |
All you have to do is to provide a second array of domains to refineList
prop. This package ships with a curated list of the ~160 most popular world domains that you can directly import and use (thanks to @mailcheck):
import { Email, domains } from '@smastrom/react-email-autocomplete'
const baseList = [
'gmail.com',
'yahoo.com',
'hotmail.com',
'aol.com',
'msn.com',
'proton.me',
]
function App() {
const [email, setEmail] = useState('')
return (
<Email
baseList={baseList}
refineList={domains}
onChange={setEmail} // or (newValue) => customSetter(newValue)
value={email}
/>
)
}
Alternatively, you can use your own array of domains or search for the one that best suits your audience.
:globe_with_meridians: Localization
This package ships with an optional hook that simplifies managing different lists of domains according to the browser's locale.
1 - Create an object and define lists for each browser locale:
export const emailProviders = {
default: [
'gmail.com',
'yahoo.com',
'hotmail.com',
'aol.com',
// ...
],
it: [
'gmail.com',
'yahoo.com',
'yahoo.it',
'tiscali.it',
// ...
],
'it-CH': [
'gmail.com',
'outlook.com',
'bluewin.ch',
'gmx.de',
// ...
],
}
import type { LocalizedList } from '@smastrom/react-email-autocomplete'
export const emailProviders: LocalizedList = {
default: [
'gmail.com',
'yahoo.com',
'hotmail.com',
'aol.com',
// ...
],
// ...
}
You may define lang codes with or without country codes.
For languages without country code (such as it
), by default it will match all browser locales beginning with it such as it
, it-CH
, it-IT
and so on.
For languages with country code (it-CH
) it will match it-CH
but not it
or it-IT
.
If you define both it-CH
and it
, it-CH
will match only it-CH
and it
will match it
, it-IT
and so on.
2 - Use the hook:
import { Email, useLocalizedList } from '@smastrom/react-email-autocomplete'
import { emailProviders } from '@/src/static/locales'
function App() {
const baseList = useLocalizedList(emailProviders)
const [email, setEmail] = useState('')
return (
<Email
baseList={baseList}
onChange={setEmail} // or (newValue) => customSetter(newValue)
value={email}
/>
)
}
Usage with internationalization frameworks or SSR
To manually set the locale, pass its code as second argument:
import { useRouter } from 'next/router'
import { emailProviders } from '@/src/static/locales'
import { Email, useLocalizedList } from '@smastrom/react-email-autocomplete'
function App() {
const { locale } = useRouter()
const baseList = useLocalizedList(emailProviders, locale)
const [email, setEmail] = useState('')
return (
<Email
baseList={baseList}
onChange={setEmail} // or (newValue) => customSetter(newValue)
value={email}
/>
)
}
Or with NextJS App router:
components/Email.tsx
'use client'
import {
Email as EmailAutocomplete,
useLocalizedList,
} from '@smastrom/react-email-autocomplete'
import { emailProviders } from '@/static/locales'
export function Email({ lang }: { lang: string }) {
const baseList = useLocalizedList(emailProviders, lang)
const [email, setEmail] = useState('')
return (
<EmailAutocomplete
classNames={classNames}
baseList={baseList}
onChange={setEmail}
value={email}
/>
)
}
app/page.tsx
import { Email } from '@/components/Email'
import { headers } from 'next/headers'
export default function Home() {
const headersList = headers()
const lang = headersList.get('accept-language')?.split(',')[0]
return (
<main>
<Email lang={lang} />
</main>
)
}
:8ball: onSelect callback
To invoke a callback everytime a suggestion is selected (either with mouse or keyboard), pass a callback to onSelect
prop:
import { Email } from '@smastrom/react-email-autocomplete'
function handleSelect(data) {
console.log(data) // { value: '[email protected]', keyboard: true, position: 0 }
}
function App() {
const [email, setEmail] = useState('')
return (
<Email
baseList={baseList}
onChange={setEmail} // or (newValue) => customSetter(newValue)
onSelect={handleSelect}
value={email}
/>
)
}
type OnSelectData = {
value: string
keyboard: boolean
position: number
}
type OnSelect = (object: OnSelectData) => void | Promise<void>
