eslint-formatter-codeclimate

library2.0.1jsnpmunverified

An ESLint formatter that outputs lint results in the Code Climate report format, suitable for integration with Code Climate's platform. Version 2.0.1 supports ESLint >=9 and requires Node.js 20+. The v2.0.0 release switched fingerprint hashing from SHA1 to SHA256, a breaking change. It offers both a CLI formatter (--format codeclimate) and a programmatic API (toCodeClimate). Unlike generic JSON formatters, this produces a Code Climate-specific JSON structure with categories, fingerprints, and relative paths.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

formatter

✓ import formatter from 'eslint-formatter-codeclimate'

✗ const formatter = require('eslint-formatter-codeclimate')

Default export is the ESLint formatter function; package is ESM-only, so require() fails with ERR_REQUIRE_ESM.

toCodeClimate

✓ import { toCodeClimate } from 'eslint-formatter-codeclimate'

✗ const { toCodeClimate } = require('eslint-formatter-codeclimate')

Named export for programmatic conversion; also ESM-only.

Programmatically converts ESLint results to Code Climate format using toCodeClimate.

import { ESLint } from 'eslint'; import { toCodeClimate } from 'eslint-formatter-codeclimate'; const cwd = process.cwd(); const eslint = new ESLint({ cwd }); const results = await eslint.lintFiles([]); const rulesMeta = eslint.getRulesMetaForResults(results); const issues = toCodeClimate(results, rulesMeta, cwd); console.log(JSON.stringify(issues, null, 2));

Debug

Known issues

breakingFingerprint hash algorithm changed from SHA1 to SHA256 in v2.0.0, altering issue fingerprints.

fix

Update any systems that rely on fingerprint consistency (e.g., deduplication) to use the new hash.

affects: >=2.0.0

breakingPeer dependency requirement changed to eslint >=9 in v2.0.0.

fix

Ensure eslint version is 9 or above.

affects: >=2.0.0

gotchaPackage is ESM-only. Using require() throws ERR_REQUIRE_ESM.

fix

Use import syntax or dynamic import().

affects: >=1.0.0

gotchaNode.js version must be 20 or greater.

fix

Upgrade Node.js to 20+.

affects: >=1.0.0

Errors

Common errors & fixes

Error [ERR_REQUIRE_ESM]: require() of ES Module /path/to/node_modules/eslint-formatter-codeclimate/index.js from /path/to/script.js not supported.

Using CommonJS require() on an ESM-only package.

fix

Use import syntax or dynamic import(), or set package type to module.

Error: Cannot find module 'eslint-formatter-codeclimate'

Package not installed or not in node_modules.

fix

Run 'npm install eslint-formatter-codeclimate'.

TypeError: toCodeClimate is not a function

Incorrect import of default export instead of named export.

fix

Use import { toCodeClimate } from 'eslint-formatter-codeclimate'.

Error: ESLint configuration error: The formatter 'codeclimate' is not found.

ESLint cannot find the formatter when used via CLI.

fix

Ensure the package is installed in the project and the formatter name matches the package name (--format codeclimate).
