9.0.0 (2020-07-03)

Features

intl-messageformat: make FormatXMLElementFn non-variadic (f2963bf)

BREAKING CHANGES

intl-messageformat: This effectively change the signature for formatter function from (...chunks) => any to (chunks) => any. This solves a couple of issues:

We received user feedback that variadic function is not as ergonomic

Right now there's not way to distinguish between 2 chunks that have the same tag, e.g on and on. The function would receive 2 chunks that are identical. By consoliding to the 1st param we can reserve additional params to provide mode metadata in the future

One column per quarter.

8.0.0 (2020-03-04)

Features

intl-messageformat: combine formatHTMLMessage into format (d59fbf1)

BREAKING CHANGES

intl-messageformat: We've modified the way we parse and format embedded XML/HTML as follow:

formatHTMLMessage has been combined with format
All tags specified must have corresponding values and will throw error if it's missing, e.g: new IntlMessageFormat("a strong").format({ b: (...chunks) => chunks })
Self-closing tags are treated as string literal by default. We don't allow formatting self-closing tags because we already use ICU {placeholder} syntax for that.
XML/HTML tags are escaped using apostrophe just like other ICU constructs.
Remove dependency on DOMParser and restrictions on void element like <link>. This effectively means you don't need to polyfill DOMParser in Node anymore

fix(intl-messageformat-parser): fix escaping for XML tag
