[language server] Apply codefix to all files

[anka-213]

Search Terms

• File is a CommonJS module; it may be converted to an ES6 module.
• Apply codefixes to all files (vscode, visual studio code)
• Convert all files from CommonJS to ES6

Suggestion

I would like to have some way to apply a specific codefix to all files in a directory. For example, convert a bunch of files from CommonJS format to the new ES6 module format using the codefix here.

Use Cases

I have a few hundred files in CommonJS module format that I want to convert to ES6 module syntax (export/import instead of exports/require).

Currently, my text editor (vscode) shows after some delay three dots at the top of the current file which, when hovered over with the mouse shows after a few more seconds delay a "quickFix" button that, when clicked, causes the current file to be converted. To convert all of my files with this method would take hours of tedious clicking.

I want some method of automating this process.

Examples

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

There are a number of external tools that do this, like https://github.com/JoshuaKGoldberg/TypeStat, so you may be able to use one of those for now.
