mvts is a a tool for moving TypeScript files and updating their relative imports. This is WIP but works on my machine :).
cargo build
mvts takes two arguments: sourcefilepath and targetfilepath.
mvts source_file.ts some_folder/another_folder/moved_source_file.ts
mvts moves source file to targetfilepath and edits it's imports so that they are correct in the new location. mvts finds all files that import moved file and update them accordingly.
