@coderaiser You'll probably be able to spot the issue instantly, but I keep running into this:

[coderaiser]

const output = putout(file.source, {
    plugins: [
        ['remove-unused-variables', removeUnusedVariables]
    ]
});

Let's use full name remove-unused-variables :).

That worked thanks!!

Do you know of a way to preserve formatting via recast?

[coderaiser]

This is how recast works when it has a little code to work with 🤷. I usually fix this with eslint-plugin-putout which solves all formatting issues.

Anyways I’m working on @putout/printer which just makes good formatting each time, not trying to preserve anything. It is much easier in maintenance and faster then recast.

You can try it using:

const output = putout(file.source, {
    printer: 'putout',
    plugins: [
        'remove-unused-variables',
    ]
});
