TypeScript security scanning for local and CI review.

What TypeScript means here.

Code Radar reviews TypeScript repositories where they live, combining supported source checks, secret detection, dependency evidence, code-health signals, and portable reports in one local workflow.

Evidence to inspect

Verify the input scope, finding detail, workflow handoff, and product boundary before you install or buy.

CriterionEvidence to inspectBoundary
Input scopeSelected files, configuration, scan mode, and enabled rules.Only included paths and configured checks are evaluated.
Finding detailFile, line, rule ID, severity, explanation, and repair direction.Illustrative output is not a result from your repository.
Workflow handoffLocal result, report format, agent context, and optional CI signal.Enable exports or CI only when the workflow needs them.
Decision fitUse the same criteria on a real repository before choosing a plan or tool.No universal winner or guaranteed outcome is claimed.

The problem this page helps clarify

The useful question is where TypeScript changes the review loop: what enters the scan, who acts on a finding, and which evidence moves forward. TypeScript source files (.ts, .tsx, package.json, package-lock.json) plus npm and lockfile advisories evidence in one local review path.

  • Audience: Developers maintaining TypeScript repositories and their dependency manifests.
  • Focus: TypeScript source files (.ts, .tsx, package.json, package-lock.json) plus npm and lockfile advisories evidence in one local review path.
  • Review question: What does TypeScript cover in practice?

Coverage and concrete signals

For TypeScript, inspect the concrete scope below instead of relying on a category label. File-level source findings, secret checks, dependency advisories, and SARIF-ready output for TypeScript.

  • Focus: TypeScript source files (.ts, .tsx, package.json, package-lock.json) plus npm and lockfile advisories evidence in one local review path.
  • Workflow: Files: .ts, .tsx, package.json, package-lock.json
  • Coverage and concrete signals: .ts, .tsx, package.json, package-lock.json, npm and lockfile advisories, SARIF

From local signal to shared gate.

TypeScript: Use the smallest workflow that proves value. Each later step should reuse evidence the team already understands. TypeScript source files (.ts, .tsx, package.json, package-lock.json) plus npm and lockfile advisories evidence in one local review path.

Evidence to inspect before you trust the result.

TypeScript: A useful result must be explainable to a developer and portable to the next review surface. Inspect the concrete evidence below before changing team policy. File-level source findings, secret checks, dependency advisories, and SARIF-ready output for TypeScript.

  • Files: .ts, .tsx, package.json, package-lock.json
  • Exact file location, rule context, severity, confidence, and remediation guidance.
  • Terminal output, SARIF, JSON, or HTML artifacts generated from the same finding set.
  • Source stays in the workspace or CI runner where the scan executes.

Good fit and limits

Use TypeScript when Developers maintaining TypeScript repositories and their dependency manifests. Keep the boundary explicit: Coverage depends on parsers, manifests, lockfiles, and rules; runtime behavior still needs complementary testing.

Run the local proof before adopting a shared gate.

  • Good fit: Developers maintaining TypeScript repositories and their dependency manifests.
  • Not a fit / do not overreach: Coverage depends on parsers, manifests, lockfiles, and rules; runtime behavior still needs complementary testing.

Questions to verify before rollout

These questions keep the decision tied to observable evidence rather than a broad product promise.

What does TypeScript cover in practice?

TypeScript: The practical scope is TypeScript source files (.ts, .tsx, package.json, package-lock.json) plus npm and lockfile advisories evidence in one local review path.. Start with the listed entities or files and confirm the result on representative code.

Which evidence should I inspect for TypeScript?

TypeScript: Inspect File-level source findings, secret checks, dependency advisories, and SARIF-ready output for TypeScript. Keep the source location, rule or comparison context, and exported artifact together.

What should I not infer from TypeScript?

TypeScript: Do not infer universal coverage. Coverage depends on parsers, manifests, lockfiles, and rules; runtime behavior still needs complementary testing. Use the relevant comparison or workflow page to test the boundary before changing policy.

What should I try first for TypeScript?

TypeScript: Start with a local run, review one real finding, then choose the linked report, agent, CI, or trust workflow that matches the next decision.

Local SASTLocal SAST for Developers and CI

Developer-first static application security testing that scans source locally, emits SARIF for GitHub code scanning, and gives coding agents deterministic fix context.

RulesSupported security rules

Inspect rule scope, evidence, and safer code paths.

ProofSee sample report

Inspect the fields and formats in a sample finding.

Validate the workflow on your own code.

Start with one local scan, inspect the evidence, and expand to reports, agents, or CI only when the signal is useful.
