v0.1.0

msw-inspector v0.1.0

Initial release of msw-inspector, a CLI and GitHub Action for finding gaps in MSW mock coverage.

Highlights

• Scan MSW handlers from http.* and legacy rest.* APIs.
• Scan real API calls from fetch, window.fetch, globalThis.fetch, and common axios call shapes.
• Compare handlers against actual API usage and report:
  • mocked API calls
  • unmocked API calls
  • stale handlers
  • unsupported dynamic patterns
• Emit both text output and stable JSON output with schemaVersion: 1.
• Ship a thin GitHub Action that publishes job summaries and optional sticky PR comments from the CLI JSON report.

Install

npm install -D msw-inspector

Example

npx msw-inspector --report-file msw-inspector.json --format json

First-release scope

This release is intentionally narrow and static-analysis-first. It favors explicit unsupported diagnostics over guessing at dynamic patterns.

Included in v0.1.0:

• direct MSW http.* and rest.* handler extraction
• static string, template, regex, and URL-based matcher resolution
• same-file axios.create(...) instance support
• coverage matching by HTTP method and normalized path

Not included yet:

• custom API wrapper inference
• cross-file constant resolution
• GraphQL, WebSocket, or SSE analysis
• baseline coverage deltas in the GitHub Action

Validation

Verified locally with:

• npm run check
• npm run build
