Scrape Julia package metadata from the official Julia General Registry. Search for packages by name or fetch specific packages β€” get UUID, latest version, repository URL, dependencies, and more.

Features

  • Search packages by name query (prefix and substring matching)
  • Fetch specific packages by exact name
  • Extracts: package name, UUID, latest version, repository URL, dependencies, source URL
  • No authentication required β€” uses publicly available GitHub raw content
  • Handles the full Julia General Registry (10,000+ packages)

Mode: searchPackages

Search the Julia General Registry for packages whose name matches the query string. Prefix matches are ranked first, followed by substring matches.

Example input:

{
"mode":"searchPackages",
"searchQuery":"DataFrames",
"maxItems":10
}

Mode: getByName

Fetch specific packages by their exact registered name (case-insensitive).

Example input:

"mode":"getByName",
"packageNames":["DataFrames","Plots","Flux"],

Data Source

Data is sourced directly from the Julia General Registry on GitHub β€” the official central registry for Julia packages. No authentication is required.

FAQs

Q: How many Julia packages are in the registry? A: The Julia General Registry contains over 10,000 registered packages.

Q: Does the actor require a GitHub API token? A: No. The actor fetches raw TOML files directly from raw.githubusercontent.com, which does not require authentication.

Q: What if a package has no description? A: The description field is omitted. Julia's Package.toml format does not always include a description field.

Q: How is the latest version determined? A: The actor reads Versions.toml from the registry and takes the last listed version entry.

Q: Why is there a registryUrl and a sourceUrl? A: registryUrl points to the package's folder in the Julia General Registry on GitHub. sourceUrl points to the JuliaHub page, which provides a richer browsing experience.

Q: Can I fetch a specific version? A: The actor always retrieves the latest registered version. Fetching specific versions is not supported.
