Overview

While Working on a project, we might have done copy pasting the code or may be unknowingly repeating the same structural code in our project. Here

It might be a block of code or may be single lines of codes being repeated cross the files.

This package is inspired by true post-production bug. It leads us to the unique, well structured code with nonrepetitive LOC or blocks.

Here we have used ASTs. AST stands for Abstract Syntax Tree. Each compiler or parser generates your source code into ASTs before , e.g. BlockStatement, VariableDeclaration, ObjectExpression, etc. By default, it searches nodes with matching identifiers and literals for copy-paste code of block.

The tool accepts a list of paths to parse and prints any found matches. Any directories among the paths are walked recursively, and only .js, .jsx, .ts , .tsx files are analyzed. Any node_modules folders are also ignored.

npm install -g jsxtsxscanner
