shevyjs | Configurable Vertical Rhythm & Typography in CSS-in-JS | Frontend Utils library

Shevy is available as a module from npm:.
There are a few differences between v1 to v2, so here's how to make those changes. In v1, shevy was an instance of the Shevy class. Because of this, certain values were made properties of the class that really didn't need to be. An example would be this.baseFontScale. There isn't a good reason for this to need to be on the Shevy class. With the conversion to a simple factory function, it was easy to keep certain values and functions private. This tidies up the exposed API to just the properties for styles, and the methods listed above. This also improves the types for the project, which will likely improve your editor experience with faster Intellisense for shevy objects.
The default import is no longer a Shevy class constructor. It is the createShevy factory function.
Replace instances of new Shevy(options) with createShevy(options)
Some options properties were renamed: baseFontScale is now just fontScale addMarginBottom is now includeMarginBottom
Some options properties were modified precision and usePrecision are now just precision. precision is a nullable property now, replacing the need for two options. proximity and proximityFactor are now just proximity. proximity is a nullable property now, replacing the need for two options.
Several properties are no longer accessible on the shevy object
