This will re-write the files `path/to/file.js` and `another/file.js` by transforming them with the babel plugin `transform-module-name`. Multiple plugins may be specified, and multiple files or directories may be re-written at once.
This will re-write the files `path/to/file.js`, `another/file.js`, and any supported files found in `a/directory` by transforming them with the babel plugin `transform-module-name`. Multiple plugins may be specified, and multiple files or directories may be re-written at once.
Note that TypeScript support is provided by babel and therefore may not completely support all valid TypeScript code. If you encounter an issue, consider looking for it in the [babel issues labeled `area: typescript`](https://github.com/babel/babel/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen+label%3A%22area%3A+typescript%22+) before filing an issue with babel-codemod.
Plugins may also be loaded from remote URLs, including saved [AST Explorer](https://astexplorer.net/) URLs, using `--remote-plugin`. This feature should only be used as a convenience to load code that you or someone you trust wrote. It will run with your full user privileges, so please exercise caution!
