What command did you run?

oxlint

What does your .oxlintrc.json (or oxlint.config.ts) config file look like?

import { defineConfig, type OxlintConfig } from "oxlint";

export default defineConfig<OxlintConfig>({
    jsPlugins: [{
        name     : "react-js",
        specifier: "eslint-plugin-react",
    }],
    rules: {
        "react-js/jsx-equals-spacing"          : [ "error", "never" ],
    },
});

What happened?

I am wanting to use the rule react/jsx-equals-spacing via a jsPlugin, however it is producing false reports in code such as below.

const myElement = (subject = "Hello World") => {
    return (
        <span className="email-compose-field-label main">
                      ^^^
            Subject: {subject}
        </span>
    );
};

The rule reports that a space is found after the className=.

The rule makes use of isSpaceBetweenTokens to find a space between the "=" Punctuator and "email-compose-field-label main" Literal.

Within isSpaceBetweenTokens the getTokenOrComment returns a JSXText for this string literal ""email-compose-field-label main"" and the regex considers this to contain a whitespace.

getTokenOrComment at an index within a string literal shouldn't be returning a JSXText. Both the ESTree AST and Rust AST consider it as a string literal.

If it helps with testing, I found that replacing isSpaceBetweenTokens in this rule with isSpaceBetween allows it to behave as expected.
