List formatting

When working with lists of items, you might want to format them as conjunctions or disjunctions.

Formatting aspects, like the used separators, differ per locale:

  • "HTML, CSS, and JavaScript" in en-US
  • "HTML, CSS und JavaScript" in de-DE

List formatting can be applied with the useFormatter hook:

import {useFormatter} from 'next-intl';
function Component() {
  const format = useFormatter();
  const items = ['HTML', 'CSS', 'JavaScript'];
  // Renders "HTML, CSS, and JavaScript"
  format.list(items, {type: 'conjunction'});
  // Renders "HTML, CSS, or JavaScript"
  format.list(items, {type: 'disjunction'});

See the MDN docs about ListFormat (opens in a new tab) to learn more about the options that you can provide to the list function or try the interactive explorer for Intl.ListFormat (opens in a new tab)).

Note that lists can can currently only be formatted via useFormatter, there's no equivalent inline syntax for messages at this point.

To reuse list formats for multiple components, you can configure global formats.

How can I render an array of messages?

Formatting of React elements

Apart from string values, you can also pass arrays of React elements to the formatting function:

import {useFormatter} from 'next-intl';
function Component() {
  const format = useFormatter();
  const users = [
    {id: 1, name: 'Alice'},
    {id: 2, name: 'Bob'},
    {id: 3, name: 'Charlie'}
  const items = => (
    <a key={} href={`/user/${}`}>
  return <p>{format.list(items)}</p>;


  <a href="/user/1">Alice</a>, <a href="/user/2">Bob</a>, and
  <a href="/user/3">Charlie</a>

Note that format.list will return an Iterable<ReactElement> in this case.
