tslint-to-eslint-config

library2.16.0jsnpmunverified

Automated tool to convert TSLint configuration to the closest reasonable ESLint equivalent, facilitating migration from the deprecated TSLint to ESLint. Current stable version is 2.16.0, released with minor fixes and dependency updates. It reads existing linter, TypeScript, and package configs, generates an .eslintrc.js, and supports CLI flags for customization. Key differentiators: community-maintained under typescript-eslint, handles rule mapping with fallback to eslint-plugin-tslint for unmatched rules, and includes inline comment conversion.

Code

Verified usage

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

convertConfig

✓ import { convertConfig } from 'tslint-to-eslint-config'

✗ const convertConfig = require('tslint-to-eslint-config')

Package is ESM-only from v2.13+; CommonJS require does not work.

TSLintToESLintResult

✓ import type { TSLintToESLintResult } from 'tslint-to-eslint-config'

✗ import { TSLintToESLintResult } from 'tslint-to-eslint-config'

Type import needed for TypeScript; named import will not exist at runtime.

convertComments

✓ import { convertComments } from 'tslint-to-eslint-config/converters'

✗ import { convertComments } from 'tslint-to-eslint-config'

Utility function is in a subpath export; not exported from main entry.

Reads TSLint config and generates ESLint config object. Requires Node >=14.0.0.

import { convertConfig } from 'tslint-to-eslint-config'; async function main() { const result = await convertConfig({ tslint: './tslint.json', typescript: './tsconfig.json', eslint: './.eslintrc.js', package: './package.json', prettier: true, comments: true, }); console.log(JSON.stringify(result.config, null, 2)); } main().catch(console.error);

Debug

Known issues

breakingv2.13.0 switched to ECMAScript modules (ESM). CJS require() no longer works.

fix

Use import syntax and ensure your project is ESM or use dynamic import.

affects: >=2.13.0

gotchaThe package expects Node >=14.0.0. Older versions will fail with syntax errors.

fix

Upgrade Node to 14 or later.

affects: <2.13.0

deprecatedTSLint is deprecated. This tool is for migration only; not intended for ongoing use.

fix

Use ESLint directly after migration.

affects: *

gotchaSome TSLint rules have no ESLint equivalent and are wrapped with eslint-plugin-tslint, which may degrade performance.

fix

Manually replace wrapped rules with native ESLint rules when possible.

affects: *

breakingv2.12.0 removed integration with deprecated Prettier ESLint configs. Config output may differ.

fix

Check generated config for Prettier settings and adjust manually if needed.

affects: >=2.12.0

Errors

Common errors & fixes

Cannot find module 'tslint-to-eslint-config'

Package not installed or not using ESM import.

fix

Install package (npm install --save-dev tslint-to-eslint-config) and use import syntax.

SyntaxError: Unexpected token 'export'

Node version <14 or CommonJS environment trying to load ESM.

fix

Upgrade Node to >=14 and use import syntax or run with --experimental-modules.

Error: TSLint configuration file not found: ./tslint.json

Missing or incorrect path to TSLint config.

fix

Specify correct path with --tslint flag or ensure tslint.json exists in working directory.
