tape-eslint

1.2.1 verified Fri May 01 auth: no javascript

Integrate ESLint linting into tape test suites. Version 1.2.1 (stable, infrequent releases) allows running ESLint as part of tape tests in the same Node process, reducing overhead versus a separate lint step. Supports customization of file patterns, ignores, and ESLint CLIEngine options. Designed for Node.js, it gracefully disables itself in browserified test environments. Requires ESLint as a peer dependency.

Common errors

error Error: Cannot find module 'eslint' ↓

cause tape-eslint requires eslint as a peer dependency; it is not installed.

fix

npm install --save-dev eslint

error Error: Cannot find module 'tape-eslint' ↓

cause tape-eslint is not installed.

fix

npm install --save-dev tape-eslint

error TypeError: lint is not a function ↓

cause Using ESM import (import lint from 'tape-eslint') which is not supported.

fix

Use const lint = require('tape-eslint') instead.

Warnings

deprecated Package is unmaintained; last release 2016-08-03. ESLint versions after 1.x may break compatibility. ↓

fix Use tape-eslint 1.2.1 with ESLint 1.x or consider alternatives like eslint-tape.

gotcha Browserify usage: require('tape-eslint')() returns a noop function in browser environments, potentially confusing users expecting linting to run. ↓

fix No action needed; it's by design but should be documented clearly.

gotcha ESLint peer dependency is not automatically installed; must be installed separately. ↓

fix Run npm install --save-dev tape-eslint eslint.

deprecated Uses deprecated eslint.CLIEngine API; may break with ESLint >=2.0. ↓

fix Use a newer package or pin ESLint to 1.x.

Install

npm install tape-eslint

yarn add tape-eslint

pnpm add tape-eslint

Imports

ESM import not supported; must use require.

tape test usage
```
const test = require('tape'); test('lint', require('tape-eslint')())
```
Default behavior lints all .js and .jsx files; customize via options object.

Quickstart

Set up tape-eslint in a tape test with custom file patterns and ESLint config.

const test = require('tape');
const lint = require('tape-eslint');

test('eslint', lint({
  files: ['index.js', 'test/*.js'],
  ignore: ['dist/**'],
  eslint: { configFile: '.eslintrc' }
}));
