# Go Modules Scraper - Package Versions, Metadata & Dependencies (`klondikeking/go-modules-scraper`) Actor Extract Go module metadata from proxy.golang.org: versions, latest release, go.mod Go version, and dependencies. Ideal for dependency auditing and Go ecosystem research. - **URL**: https://apify.com/klondikeking/go-modules-scraper.md - **Developed by:** [Pierrick McD0nald](https://apify.com/klondikeking) (community) - **Categories:** Developer tools - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, 0 bookmarks - **User rating**: No ratings yet ## Pricing Pay per usage This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Go Modules Scraper - Package Versions, Metadata & Dependencies Extract comprehensive metadata from the Go Module Mirror (proxy.golang.org) for any list of Go modules. This Actor returns all published versions, the latest version with its timestamp, the Go version declared in the latest go.mod, and a complete list of direct dependencies. It is ideal for Go ecosystem research, dependency auditing, license tracking, vulnerability analysis, and keeping an internal software catalog up to date. The Go Module Mirror is a public, read-only API maintained by Google. It serves version lists, version metadata, and go.mod files without authentication, making this Actor fast, reliable, and cost-effective. No browser rendering or anti-bot workarounds are required. ### Use Cases - **Dependency auditing** — Pull the latest Go version and direct dependencies for a set of modules to detect outdated or risky transitive dependencies. - **Software cataloging** — Build an internal inventory of Go libraries used across your organization with version history and dependency counts. - **Ecosystem research** — Measure version velocity, minimum Go version requirements, and dependency graph density across popular open-source modules. - **Vulnerability analysis** — Cross-reference module versions and dependencies with security advisory databases. ### Input | Field | Type | Required | Description | |-------|------|----------|-------------| | `modulePaths` | Array | Yes | List of Go module paths, e.g., `github.com/spf13/cobra`. | | `maxVersions` | Number | No | Maximum versions recorded per module (default: 100, 0 = unlimited). | | `includeGoMod` | Boolean | No | Fetch latest go.mod to extract Go version and dependencies (default: true). | | `proxyConfiguration` | Object | No | Proxy configuration. Apify proxy is included by default. | ### Output The Actor outputs a dataset with one row per module: ```json { "modulePath": "github.com/spf13/cobra", "moduleName": "cobra", "versionsCount": 24, "versions": "v1.9.0, v1.8.0, v1.7.0, ...", "latestVersion": "v1.9.0", "latestTime": "2025-02-12T14:30:00Z", "goVersion": "1.15", "dependenciesCount": 3, "dependencies": "github.com/cpuguy83/go-md2man/v2, github.com/inconshreveable/mousetrap, github.com/spf13/pflag", "sourceUrl": "https://proxy.golang.org/github.com/spf13/cobra", "error": "" } ```` ### Pricing Pay per event: $0.001 per module extracted. ### Limitations - Only public modules available on proxy.golang.org can be fetched. Private modules or modules excluded from the mirror are not supported. - The Go Module Mirror caches data, so very recent releases may take a few minutes to appear. - Indirect dependencies are not separated from direct dependencies in the current version. ### FAQ **Q: Can I scrape all Go modules?** A: No. The Actor processes the module paths you provide. Use it to audit specific libraries rather than crawl the entire ecosystem. **Q: Do I need a proxy?** A: Apify proxy is enabled by default and recommended for production runs. Direct requests may work for small tests. ### Changelog - **v1.0.0** — Initial release # Actor input Schema ## `modulePaths` (type: `array`): List of Go module paths to scrape (e.g., github.com/spf13/cobra, golang.org/x/net). Leave empty to scrape a curated set of popular modules. ## `maxVersions` (type: `integer`): Maximum number of versions to record per module. Use 0 for unlimited. ## `includeGoMod` (type: `boolean`): If enabled, fetches the latest go.mod to extract Go version and direct dependencies. ## `proxyConfiguration` (type: `object`): Configure proxy for scraping. Apify proxy is included by default. ## Actor input object example ```json { "modulePaths": [ "github.com/spf13/cobra", "github.com/gin-gonic/gin", "golang.org/x/net" ], "maxVersions": 10, "includeGoMod": true, "proxyConfiguration": { "useApifyProxy": true } } ``` # Actor output Schema ## `results` (type: `string`): No description ## `stats` (type: `string`): No description # API You can run this Actor programmatically using our API.
