What should I use instead of tslint?
The ecosystem moved to typescript-eslint, a separate project that took over the same job. typescript-eslint is not a drop-in replacement, so expect to change call sites.
How to migrate from tslint to typescript-eslint
typescript-eslint documents the TSLint story and a rule-by-rule comparison; tslint-to-eslint-config can convert an existing tslint.json into an ESLint config as a starting point.
Why tslint is on this list
Palantir announced in February 2019 that TSLint would be deprecated in favour of ESLint with first-class TypeScript support, and the final release, 6.1.3, shipped in July 2020. The repository was archived in March 2021 and the npm package carries a deprecation notice pointing at that announcement. typescript-eslint is the project the TypeScript and ESLint communities backed as the successor.
The succession is settled: primary sources agree and the ecosystem has already moved.
tslint alternatives
Beyond the primary recommendation, these are credible for tslint's use case:
@typescript-eslint/eslint-plugin— view on npmeslint— view on npmoxlint— view on npm
Check your own project for tslint
npx dead-deps --all --min-state unmaintainedRun that in the directory holding your lockfile. If tslint is anywhere in your tree — a direct dependency or buried under something else — it appears in the report with this verdict, this successor and the same evidence links, alongside anything else that has stopped moving. Nothing is uploaded; the scan reads your lockfile locally and queries public registry metadata.
Exit code 1 means something was flagged, which makes npx dead-deps --min-state deprecated usable as a CI gate. See how verdicts are produced.
