import-x/no-import-module-exports

🔧 This rule is automatically fixable by the --fix CLI option.

Reports the use of import declarations with CommonJS exports in any module except for the main module.

If you have multiple entry points or are using js:next this rule includes an exceptions option which you can use to exclude those files from the rule.

Options

exceptions

• An array of globs. The rule will be omitted from any file that matches a glob in the options array. For example, the following setting will omit the rule in the some-file.js file.

"import-x/no-import-module-exports": ["error", {
    "exceptions": ["**/*/some-file.js"]
}]
