Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

JSxTSxScanner

Scans similar block of code in your JS, JSX, TS & TSX files. Requires Node.js 6.0+. It supports ES6 & JSX

Build Status

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.

Installation

It can be installed via npm using:

npm install -g jsxtsxscanner

Usage

jsxtsxscanner <paths ...>

Scans similar block of code in your JS, JSX, TS & TSX files Example use: jsxtsxscanner ./path/to/src
