Question 1

How to migrate from TSLint to ESLint?

Accepted Answer

Use the typescript-eslint project's migration tools and follow their roadmap. It involves installing ESLint with TypeScript plugins, converting TSLint rules to ESLint equivalents, and updating configuration files, which can be time-consuming for large codebases.

Question 2

TSLint vs ESLint for TypeScript?

Accepted Answer

ESLint is the recommended choice for TypeScript now, as it's actively maintained and supports both JavaScript and TypeScript in a unified way. TSLint is deprecated, so new projects should avoid it despite its historical strengths in TypeScript-specific linting.

Question 3

How to set up TSLint in VS Code?

Accepted Answer

Install the TSLint extension for VS Code, create a tslint.json configuration file with your rules, and enable it in workspace settings. However, note that support may be limited due to deprecation.

Question 4

Is TSLint still being updated?

Accepted Answer

No, TSLint is no longer updated. The last stable release is final, and users are directed to migrate to ESLint for ongoing support and improvements.

Question 5

Can TSLint fix code automatically?

Accepted Answer

Yes, TSLint can automatically fix certain rule violations, such as formatting issues, when run via CLI or editor integrations, but this feature is now superseded by ESLint's autofix capabilities.

Question 6

What are TSLint alternatives?

Accepted Answer

ESLint with the typescript-eslint plugin is the primary alternative, offering similar functionality with better community support and integration for modern web development toolchains.
