SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill enables users to decode complex rolldown REPL share URLs to reveal the embedded source files, code, and version information for reproducing bugs or understanding shared code states.

Core Features & Use Cases

  • Decode REPL URLs: Convert base64-encoded and zlib-compressed URL hashes into readable JSON with source files and metadata.
  • File Extraction: Optionally save decoded files onto disk for local reproductions.
  • Use Case: When provided a URL like https://repl.rolldown.rs/#..., decode its contents to analyze the source code and replicate issues locally.

Quick Start

Run the decode script with the URL to view the decoded JSON summary, or include a path to save the files for debugging.

Frequently Asked Questions about rolldown-repl-decode

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I decode a rolldown REPL share URL to view the source code?

To decode a rolldown REPL share URL, the Skill processes the URL hash using base64 decoding and zlib decompression, converting it into readable JSON with source files and version data for analysis.

How do I extract source files from a rolldown REPL URL for local bug reproduction?

You can extract source files by providing the REPL URL and an optional output path to the decode script, which saves the decoded files onto your disk for local reproductions and debugging.

What encoding format does the rolldown REPL use in its shareable URL hashes?

Rolldown REPL shareable URL hashes use base64 encoding and zlib compression to embed source files and version metadata within the URL fragment.

Can I use Node.js to decompress and interpret rolldown REPL URL payloads?

Yes, this Skill utilizes built-in Node.js zlib decompression and base64 decoding to process and interpret the compressed URL payloads from rolldown REPL links.

Does decoding rolldown REPL URLs require any external dependencies?

No, decoding rolldown REPL URLs requires no external dependencies as the Skill relies solely on built-in Node.js modules for base64 decoding and zlib decompression.

What is the best way to troubleshoot a shared rolldown REPL code state?

The best way to troubleshoot a shared code state is to decode the rolldown REPL URL into structured JSON, revealing the embedded source files and version information needed to replicate issues locally.
