Questions
About typechecker
Is typechecker safe to use?
Vulert has no vulnerabilities on record for typechecker in npm at this point. That is a good signal rather than a guarantee: new vulnerabilities are published for packages all the time, so the versions you actually run are still worth monitoring.
What is typechecker's Vulert package health score?
Vulert scores typechecker 55/100, which reads as usable, but worth attention. The score weighs the vulnerability record (40), maintenance and release cadence (25), adoption from dependents and stars (20) and community signals such as the OpenSSF scorecard and forks (15).
Is the latest version of typechecker affected?
No. 9.3.0, the version you would install today, has no vulnerabilities on record against it. Earlier releases do — the version table above lists each release with what affects it.
Which version of typechecker should I use?
9.3.0 is the version Vulert recommends for the affected releases. The version table above lists every release with the vulnerabilities recorded against it, so you can confirm the range you actually run.
How many vulnerabilities does typechecker have?
0 vulnerabilities are recorded for typechecker in the npm ecosystem: 0 critical, 0 high, 0 medium and 0 low. The ledger on this page lists the same counts next to the date of the most recent disclosure.
How often are new typechecker vulnerabilities disclosed?
0 vulnerabilities were recorded for typechecker in the last 12 months. Recency matters more than a lifetime total: it shows how actively new issues are being disclosed for the package you are considering.
Which versions of typechecker are affected?
Each vulnerability on this page lists the affected version range and the fixed version to move to. Open the vulnerability for the version you actually run — fixes are specific to a release line, not to the package as a whole.
How do I monitor typechecker for upcoming vulnerabilities?
Upload the manifest or SBOM for your application at vulert.com/scanner and Vulert keeps checking the typechecker version you actually run against new disclosures, then alerts you when one affects it. There is no installation and no source-code access required.
