jsinspect
Detects copy-pasted and structurally similar JavaScript code using AST analysis for ES6, JSX, and Flow.
What is jsinspect?
jsinspect is a Node.js CLI tool that detects copy-pasted and structurally similar JavaScript code by analyzing abstract syntax trees. It helps developers identify code duplication, common boilerplate, and repeated logic that can lead to maintenance issues and technical debt. The tool supports modern JavaScript syntax including ES6, JSX, and Flow, providing configurable detection thresholds and integration options for CI/CD pipelines.
JavaScript developers and teams working on codebases where maintaining code quality and reducing duplication is a priority, especially those using modern JS syntax like ES6, JSX, or Flow.
Developers choose jsinspect for its AST-based approach that goes beyond token matching to detect structural similarities, its support for modern JavaScript ecosystems, and its flexibility in configuration and integration, making it more accurate and adaptable than many existing duplication detection tools.
