# JSR JavaScript Packages Scraper (`parseforge/jsr-packages-scraper`) Actor Browse JavaScript and TypeScript packages on the JSR registry. Each package returns the name, description, latest version, quality score, dependent count, GitHub repository, and update time. Useful for dependency research, tracking releases, and mapping the modern JS ecosystem. - **URL**: https://apify.com/parseforge/jsr-packages-scraper.md - **Developed by:** [ParseForge](https://apify.com/parseforge) (community) - **Categories:** Developer tools, Other - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, 0 bookmarks - **User rating**: No ratings yet ## Pricing from $19.00 / 1,000 results This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events. Since this Actor supports Apify Store discounts, the price gets lower 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/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.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/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 ![ParseForge Banner](https://github.com/ParseForge/apify-assets/blob/ad35ccc13ddd068b9d6cba33f323962e39aed5b2/banner.jpg?raw=true) ## 📦 JSR Packages Scraper > 🚀 **Export packages from the JSR registry in seconds.** Search by keyword or list a whole scope and get description, latest version, quality score, dependency and dependent counts, GitHub repo, and runtime compatibility on every record. JSR is the modern JavaScript and TypeScript registry for Deno, Node, Bun, and the browser. This Actor reads the public JSR API and returns a clean, ready to use feed of packages with GitHub links resolved and runtime support flattened per record. | 🎯 Target Audience | 💡 Primary Use Cases | |---|---| | JS/TS developers | Discover and compare packages | | Dev tool builders | Track the JSR ecosystem | | Package maintainers | Monitor scores and dependents | | Data analysts | Study registry growth and quality | ### 📋 What it does - Searches JSR by keyword or lists every package under a single scope. - Returns latest version, quality score, and dependency / dependent counts. - Resolves the GitHub repository into an owner/name and URL. - Flattens runtime compatibility into Node, Deno, Browser, Bun, and workerd flags. ### 📊 Data fields Each record includes: `createdAt`, `dependencyCount`, `dependentCount`, `description`, `githubRepo`, `githubUrl`, `isArchived`, `jsrUrl`, `latestVersion`, `name`, `package`, `runtimeBrowser`, `runtimeBun`, `runtimeDeno`, `runtimeNode`, `runtimeWorkerd`, `scope`, `score`, `scrapedAt`, `updatedAt`, `versionCount`. All 21 field names come from a real production run, so what you see here is what lands in your dataset. ### 🚀 How to use 1. Create a free Apify account with [this sign up link](https://console.apify.com/sign-up?fpr=vmoqkp). 2. Open the JSR Packages Scraper in the Apify Console. 3. Enter a search query or a scope, set how many records you want, and run. 4. Collect the results from the output table or the API. ### 🆘 Need Help?

Leave empty to list all packages. Ignored when a Scope is set. ## `scope` (type: `string`): Optional. List only packages under a single scope, for example std or luca (with or without the leading @). Overrides the search query. ## `maxItems` (type: `integer`): How many packages to collect per run. ## Actor input object example ```json { "maxItems": 10 } ```` # Actor output Schema ## `results` (type: `string`): No description # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "query": "", "scope": "", "maxItems": 10 }; // Run the Actor and wait for it to finish const run = await client.actor("parseforge/jsr-packages-scraper").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
