tslint-to-eslint-config

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: 🤔

• ESLint itself
• typescript-eslint, which allows TypeScript files to be linted by ESLint

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+
