mocha-eslint

library7.0.0jsnpmunverified

Run ESLint as Mocha tests without a task runner like Grunt or Gulp. Version 7.0.0 supports ESLint ^7.0.0 and requires Node ^10.12.0 or >=12.0.0. It creates separate Mocha tests for each linted path or glob pattern, with options for formatter, timeout, slow, strict mode, and context name. Unlike alternatives that require plugin registration, this package directly exposes a function to run linting in any Mocha test file.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ const lint = require('mocha-eslint');

✗ import lint from 'mocha-eslint';

Package uses CommonJS; ESM import may fail in older Node or without transpiler.

Value

✓ const lint = require('mocha-eslint');

The exported value is a function; no named exports.

Type

✓ const lint = require('mocha-eslint');

✗ import { lint } from 'mocha-eslint';

There is no named export; must import default.

Configure mocha-eslint with paths, formatter style, timeout, and strict mode, then run linting as Mocha tests.

const lint = require('mocha-eslint'); const paths = ['src', 'test/**/*.js', '!test/exclude.js']; const options = { formatter: 'stylish', alwaysWarn: true, timeout: 5000, slow: 1000, strict: false, contextName: 'eslint' }; lint(paths, options);
