eslint-formatter-rdjson

library1.0.6jsnpmunverified

An ESLint formatter that outputs results in the Reviewdog Diagnostic Format (RDFormat), enabling seamless integration with Reviewdog for automated code review in CI pipelines. Version 1.0.6 is the latest stable release. It is maintained as part of the action-eslint project by Reviewdog. Key differentiators: produces machine-parseable RDJSON output optimized for Reviewdog's diagnostic reporting, supports GitHub Actions, and works with any CI that can parse JSON.

Verified usage

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

formatter

✓ import formatter from 'eslint-formatter-rdjson'

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

ESM-only package; CommonJS require fails.

default

✓ import rdjson from 'eslint-formatter-rdjson'

✗ import { rdjson } from 'eslint-formatter-rdjson'

The package provides a default export, not named exports.

use in ESLint config

✓ format: 'rdjson'

✗ formatter: 'eslint-formatter-rdjson'

In .eslintrc or eslint.config.js, set format to 'rdjson' directly.

Shows how to use the rdjson formatter programmatically and via CLI to output Reviewdog-compatible JSON.

// Run ESLint with the rdjson formatter import { ESLint } from 'eslint'; const eslint = new ESLint({ overrideConfig: { format: 'rdjson' } }); const results = await eslint.lintFiles(['src/**/*.js']); const formatter = await eslint.loadFormatter('eslint-formatter-rdjson'); const resultText = await formatter.format(results); console.log(resultText); // Or via CLI: // npx eslint --format rdjson src/

Debug

Known issues

breakingESLint 9+ breaking changes: eslint-formatter-rdjson 1.0.6 may not work with flat config without explicit formatter support.

fix

Ensure compatibility by testing with ESLint 9 and use eslint.config.js with format: 'rdjson'.

affects: >=1.0.0

gotchaFormatter output is RDJSON, not standard ESLint JSON; cannot be piped directly to other tools that expect JSON.

fix

Pipe output to Reviewdog or parse RDJSON format accordingly.

affects: *

deprecatedThe package is bundled with reviewdog/action-eslint; standalone usage is discouraged if you are using the action.

fix

Use the official GitHub Action reviewdog/action-eslint instead of manual formatter setup.

Errors

Common errors & fixes

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

Missing or incorrect installation / CommonJS require instead of ESM import.

fix

Run npm install eslint-formatter-rdjson --save-dev and use import syntax.

TypeError: formatter is not a function

Incorrect import style; default export used as named export.

fix

Change to import formatter from 'eslint-formatter-rdjson'.

ESLint configuration error: Invalid formatter 'rdjson'

Formatter not found because the package is not installed or misconfigured.

fix

Ensure eslint-formatter-rdjson is in devDependencies and run npx eslint --format rdjson.
