no-restricted-syntax

eslint-plugin-query extends ESLint by allowing developers to create custom rules using arbitrary selectors to identify and report on specific JavaScript syntax patterns. It provides a flexible way to search, analyze, and enforce code patterns beyond standard linting rules.

Key Features

• Selector-Based Queries — Use ESLint's selector syntax to target specific AST nodes like functions, statements, or expressions.
• Customizable Reporting — Define custom messages, templates, and range limits for matched syntax.
• CLI Tool — Includes a command-line interface (esq) for one-off code searches without permanent rule configuration.
• Missing Syntax Detection — Rule to enforce minimum occurrences of specific syntax patterns in codebases.
• Badge Integration — Compatible with tools like eslint-formatter-badger to generate visual badges from query results.

Philosophy

The plugin emphasizes flexibility and exploration, enabling developers to query codebases dynamically for patterns, metrics, or anomalies without rigid predefined rules.
