Lists within messages

[ArtoszBart]

Is your feature request related to a problem? Please describe.

next-intl provides a list formatting function, such as format.list(items, {type: 'conjunction'}). However, it would be great if the t() function could accept an array as an argument, allowing you to include translated text while letting next-intl handle conjunctions or disjunctions automatically.

Describe the solution you'd like

i18next already provides a good solution, as shown here.

Describe alternatives you've considered

For example, a similar solution could look like this:

en.json

{
  "list_example": "I used {listVariable, list}"
}

.ts

const listVariable = ['Next.js', 'Typescript', 'next-intl'];
t('list_example', { listVariable, type: 'conjunction' })

the output would be:

I used Next.js, TypeScript, and next-intl.

I agree it could be useful, but next-intl currently depends on intl-messageformat which unfortunately doesn't support this (I think because it's not spec'ed by ICU).

The alternative is:

t('list', items: format.list(items));
