Custom ESLint Rules Plugin

A custom ESLint plugin providing rules to enforce best practices for error handling, logging, and consistent code structure in JavaScript/Node.js projects.

• catch-rule: Ensures all Promises have a proper .catch block to handle errors.
• custom-fields-rule: Enforces the inclusion of custom fields (timestamp, application, system, severity, reason, category) in logs.
• json-log-rule: Validates that logs are in a consistent JSON format for easier parsing by log management tools.
• return-rule: Ensures functions explicitly return a value.
• then-rule: Enforces consistent structure for .then chains in Promises, preventing deeply nested chains and ensuring correct returns.

npm install eslint-logging-rules --save-dev

import eslintPluginCustomRules from "eslint-logging-rules"; // Import your custom rules plugin

2. Enable the rules you want to enforce in the rules section:

 {
    plugins: {
      customRules: eslintPluginCustomRules,
    },
    rules: {
      "customRules/return-rule": "warn",
      "customRules/json-log-rule": "warn",
      "customRules/custom-fields-rule": "warn",
      "customRules/catch-rule": "warn",
      "customRules/then-rule": "warn",
    },
  },
