Uppy 1.25: right-to-left scripts, Ukrainian translation, Companion improvements

· 2 min read

Uppy 1.25 adds support for right-to-left scripts, Ukrainian translation and various improvements for Companion.

Just see how cool this looks, and read further for a video demo and some behind the scenes implementation sorcery:

Uppy Dashboard UI flipped for right-to-left Arabic language

Right-to-left scripts

Renée have improved support for right-to-left scripts (such as Arabic, Farsi, Hebrew). This means that Uppy UI can now be mirrored, like how you might see on sites like Wikipedia.

HTML dir attribute can be used to set the direction — any parent element of the Dashboard may have it. It’s good practice for sites to add a dir attribute on <html> element, but for backwards compatibility the Dashboard will default to left-to-right rendering.

The text direction can also be set in code using the new direction option for the Dashboard plugin. This is useful for the modal dashboard, which would typically be mounted in the <body> element, so there is no other parent element that you could set the dir attribute on (aside from <body> and <html>, which sites should do, but may not).

Head over to the #2705 PR description and code, if you are interested in how this is implemented, using new CSS properties like inline-start and inline-end with postcss-logical and postcss-dir-pseudo-class for the fallback.


@DenysNosov contributed a Ukrainian translation and fixes for Russian grammar!
