    Converts your TSLint configuration to the closest reasonable ESLint equivalent.

    👉 Did you know TSLint is deprecated? Hooray! Use tslint-to-eslint-config to expedite migrating your project onto ESLint.

    Consider taking a peek at the relevant documentation: 🤔

    Usage

    npx tslint-to-eslint-config

    (wow, so simple!)

    The tslint-to-eslint-config command reads in any existing linter, TypeScript, and package configuration files, then creates an .eslintrc.js result based on them.

    For any TSLint rules with corresponding ESLint equivalents, those equivalents will be used in the new configuration. TSLint rules without ESLint equivalents will be wrapped with eslint-plugin-tslint.

    Requires Node 10+ (LTS) and TSLint 5.18+

    FAQs

    We strongly advise reading docs/FAQs.md before planning your conversion from TSLint to ESLint.

    CLI Flags

    Each of these flags is optional:

    • comments: TypeScript configuration or file glob path(s) to convert TSLint rule flags to ESLint within.
    • config: Path to print the generated ESLint configuration file to.
    • editor: Path to an editor configuration file to convert linter settings within.
    • eslint: Path to an ESLint configuration file to read settings from.
    • package: Path to a package.json file to read dependencies from.
    • prettier: Add eslint-config-prettier to the plugins list.
    • tslint: Path to a TSLint configuration file to read settings from.
    • typescript: Path to a TypeScript configuration file to read TypeScript compiler options from.

    comments

    npx tslint-to-eslint-config --comments

    Default: none

    Indicates to convert from TSLint rule flags to ESLint inline comments. Comments such as // tslint:disable: tslint-rule-name will be converted to equivalents like // eslint-disable eslint-rule-name.

    If passed without arguments, respects the excludes, files, and includes in your TypeScript configuration.

    If passed a single file path ending with .json, that is treated as a TypeScript configuration file describing with files to convert.

    npx tslint-to-eslint-config --comments tsconfig.json

    If passed any other arguments, those are treated as glob paths for file paths to convert:

    npx tslint-to-eslint-config --comments 'src/**/*.ts'

    config

    npx tslint-to-eslint-config --config .eslintrc.json

    Default: .eslintrc.js

    Path to print the generated ESLint configuration file to.

    The file extension of this path will be used to determine the format of the created file:

    • .js file paths will be written module.exports = ... JavaScript
    • Other file paths will default to JSON

    editor

    npx tslint-to-eslint-config --editor ./path/to/.vscode/settings.json

    Default: .vscode/settings.json

    Path to an editor configuration file to convert settings settings within. Any VS Code style editor settings for TSLint will be converted to their ESLint equivalents.

    eslint

    npx tslint-to-eslint-config --eslint ./path/to/eslintrc.js

    Default: --config's value

    Path to an ESLint configuration file to read settings from. The generated ESLint configuration file will include any settings imported from this file.

    package

    npx tslint-to-eslint-config --package ./path/to/package.json

    Default: package.json

    Path to a package.json file to read dependencies from. This will help inform the generated ESLint configuration file's env settings.

    prettier

    npx tslint-to-eslint-config --prettier

    Default: false

    Add eslint-config-prettier to the list of ESLint plugins. We highly recommend you use Prettier for code formatting.

    When --prettier isn't enabled:

    • If the output configuration already doesn't enable any formatting rules, it'll extend from eslint-config-prettier.
    • Otherwise, a CLI message will suggest running with --prettier.

    tslint

    npx tslint-to-eslint-config --tslint ./path/to/tslint.json

    Default: tslint.json

    Path to a TSLint configuration file to read settings from. This file is piped into TSLint's --print-config to generate the list of rules to enable in the generated ESLint configuration file.

    typescript

    npx tslint-to-eslint-config --typescript ./path/to/tsconfig.json

    Default: tsconfig.json

    Path to a TypeScript configuration file to read TypeScript compiler options from. This will help inform the generated ESLint configuration file's env settings.
