Overview

Pure TypeScript JSON syntax validator using Node's built-in JSON.parse. Detects parse errors and duplicate keys in JSON files. No external binary required.

| Property | Value | |----------|-------| | Tool ID | jackson | | Codacy UUID | 4f94ee55-6b76-4765-8f38-9ebb3920762b | | Strategy | Native | | Languages | JSON | | Binary | None — pure TypeScript |

Patterns

| Pattern ID | Description | |------------|-------------| | jackson_parse-error | JSON syntax error | | jackson_duplicate-keys | Duplicate keys in JSON object |

Updating patterns

# Re-fetch pattern metadata from the Codacy API
pnpm prefetch

# Verify the output
cat src/patterns.json

The prefetch script calls packages/tools/scripts/fetch-patterns.mjs with the tool UUID to download pattern metadata (IDs, categories, severity levels) from the Codacy API.

After fetching, commit the updated src/patterns.json.

Development

pnpm build    # Build with tsup
pnpm test     # Run tests

Since this is a Native adapter, no external binary is needed. All analysis is done in TypeScript.
