As time goes on, extra updates to the use-baseline rule will land—and as they do, they are going to be coated right here and in different weblog posts as crucial.
browserslist-config-baseline launches
Fashionable toolchains use a number of instruments which are influenced by a Browserslist configuration (or assumed default). These configurations are utilized by instruments akin to PostCSS or Babel, and their output could be influenced by the content material of them.
We have lengthy wished to see tooling take a Baseline goal as enter—akin to Broadly or Newly obtainable, and even Baseline 2024, for instance—and output a sound Browserslist question. Now that the browserslist-config-baseline bundle has been launched, it is attainable so that you can just do that.
