history
Project history and usage
Synchrony is a JavaScript cleaner and deobfuscator aimed primarily at output from javascript-obfuscator and obfuscator.io. Its public history is thin, but the official repository and release list show a focused TypeScript CLI and web-demo tool that became packageable through npm-style workflows and Homebrew.
Project history
The official README describes Synchrony as a JavaScript cleaner and deobfuscator, primarily for javascript-obfuscator output. It exposes a hosted web version, an API reference, and a CLI command named `synchrony` for deobfuscating files.
The README states that there is no user configuration yet and that the string decoder works automatically, which keeps the command-line surface small.
Adoption history
The GitHub repository shows a TypeScript project with public releases, and the releases page lists v2.4.5 as the latest release in November 2023. The input package metadata lists Homebrew and Nix packaging, while the README documents global npm, yarn, and pnpm installation under the `deobfuscator` package.
How it is used
Typical usage is to install the deobfuscator globally, fetch or provide an obfuscated JavaScript file, and run `synchrony deobfuscate file.js`, producing a cleaned output file. The README asks users reporting transformer errors to provide terminal output and a reproducible obfuscated file or config.
Why package nerds care
Synchrony is package-manager interesting because it packages an AST-heavy reverse-engineering workflow as a simple CLI and web app. It also illustrates a common JavaScript-tooling pattern: the package name, executable name, GitHub repository, generated docs, and hosted demo do not all share one exact label.
Timeline
- 2023: GitHub releases list v2.4.5 as the latest public release.
- Current README: Documents hosted use at deobfuscate.relative.im, npm-family global installs, and the `synchrony deobfuscate` command.
Related projects
- The README explicitly targets javascript-obfuscator and obfuscator.io output, and suggests trying older Synchrony versions or another deobfuscator when old obfuscator artifacts do not cleanly deobfuscate.
