lint-and-ts-configs

1.2.9 verified Fri May 01 auth: no javascript maintenance

A shared configuration package for ESLint, TypeScript, and semantic-release, providing base configurations for linting and TypeScript compilation. Version 1.2.9 (latest) is stable, with infrequent releases. Designed for monorepos and projects needing consistent linting and TypeScript settings without manual setup. Differentiators include a unified config approach for ESLint, TSConfig, and semantic-release, though documentation is sparse and updates are rare. Note: project seems to be in maintenance mode, last release in 2021.

Warnings

breaking v1.0.1 changed import/extensions config, requiring update to ESLint extends path if coming from v1.0.0 ↓

fix Update extends path to './node_modules/lint-and-ts-configs/lib/eslint/base.js' if using v1.0.1+

gotcha All configs must be referenced with a relative path (./node_modules/...) in extends, not a package name ↓

fix Use './node_modules/lint-and-ts-configs/lib/...' instead of 'lint-and-ts-configs/lib/...'

gotcha semantic-release config requires 'lib/' in the path: 'lint-and-ts-configs/lib/semantic/base' ↓

fix Use extends: 'lint-and-ts-configs/lib/semantic/base'

deprecated Package has not been updated since 2021; TypeScript and ESLint rules may be outdated ↓

fix Consider migrating to a more maintained config package like @typescript-eslint/eslint-plugin defaults

Imports

ESLint config

wrong

require('lint-and-ts-configs').eslint

correct

module.exports = { extends: ['./node_modules/lint-and-ts-configs/lib/eslint/base.js'] }

Use relative path to node_modules in extends, not a direct require.

semantic-release config

wrong

extends: 'lint-and-ts-configs/semantic/base'

correct

module.exports = { extends: 'lint-and-ts-configs/lib/semantic/base', repositoryUrl: '...' }

Must include 'lib/' in the path.

TypeScript config

wrong

{"extends": "lint-and-ts-configs/tsconfig/node"}

correct

{"extends": "./node_modules/lint-and-ts-configs/lib/tsconfig/node.json"}

Use absolute path relative to project root, include .json extension.
