@noctcore/eslint-plugin-observability

Structured-logging discipline rules — context objects over interpolated messages, no sensitive fields in logs, no error-detail loss. Flat-config only, ESLint 9+.

Install

bun add -D @noctcore/eslint-plugin-observability   # or npm i -D / pnpm add -D

Use

// eslint.config.js
import observability from '@noctcore/eslint-plugin-observability';

export default [
  observability.configs.recommended,
];

Or wire rules individually:

import observability from '@noctcore/eslint-plugin-observability';

export default [
  {
    plugins: { 'noctcore-observability': observability },
    rules: {
      'noctcore-observability/structured-log-arguments': ['error', { loggers: ['log', 'audit'] }],
    },
  },
];

Rules

| Rule | Description | Recommended | | --- | --- | --- | | structured-log-arguments | Pass dynamic values in a structured context object, not interpolated into the message string. | error | | no-sensitive-fields-in-logs | Name-heuristic guard against writing credentials/secrets into log sinks. | warn | | no-error-detail-loss | A catch block that reports failure must log the error itself, not only e.message. | error |
