eslint-plugin-flowtype-errors

library4.5.0jsnpmunverified

An ESLint plugin that wraps Flow errors and displays them as ESLint errors. Version 4.5.0 is the latest stable release. It allows any editor with ESLint support to also show Flow type errors, reducing configuration complexity by eliminating the need for a separate Flow linter integration. Maintained actively with frequent dependency updates. Supports Flow >=0.93.0 and ESLint >=5.16.0. Only works on 64-bit operating systems; Windows 32-bit is not supported.

Shows how to install and configure the plugin with ESLint, enabling Flow errors as ESLint errors.

// Install the plugin and required peer dependencies // npm install --save-dev eslint eslint-plugin-flowtype-errors flow-bin // .eslintrc.js module.exports = { plugins: ['flowtype-errors'], extends: ['plugin:flowtype-errors/recommended'], // Optional: specify Flow path or options settings: { flowtype: { onlyFilesWithFlowAnnotation: true, }, }, }; // Now ESLint will show Flow type errors in your editor // Example file with Flow: // @flow function foo(x: number): string { return x; } // ESLint reports Flow error: string expected number
