fervid_transform

Part of the fervid project, an all-in-one Vue compiler. This crate is responsible for the transformations in the template, such as optimizing the AST or transforming the JS/TS expressions in the AST nodes.

In the future this crate may accommodate the <style> transformations as well, which are currently in its own crate.
