sourcemap-updater
A tool help to modify css and update sourcemap automatically.
Assume that you have a css (maybe generated via sass/postcss
) and a corresponding sourcemap. If you want to modify the css (such as delete one declaration, change a prop value), you could modify directly, but the sourcemap would be inaccurate.
This lib will help you modify css (more convenient/powerful), and update sourcemap automatically. This means you no longer need to care about sourcemap when you modify css.
