NugetScraper

NugetScraper is an HTML parser that reads an HTML page retrieved from NuGet.org and provides a list containing NuGet packages released by a specified organization.

Example

A typical usage example would be as follows:

...
public final class Demo {

    public static void run(String organizationName)
            throws IOException, InterruptedException {
        var urlBase = "https://www.nuget.org";
        var id = URLEncoder.encode(organizationName, StandardCharsets.UTF_8);
        var request = HttpRequest.newBuilder()
                .uri(URI.create(urlBase + "/profiles/" + id + "/"))
                .build();
        var client = HttpClient.newHttpClient();
        var response = client.send(request, HttpResponse.BodyHandlers.ofString());
        var profile = NugetScraper.toProfile(response.body());

        for (var i : profile.packageList()) {
            System.out.println(i.title() + ":" + i.totalDownloads());
        }
        var maybePath = profile.nextPageUrl();
        if (maybePath.isPresent()) {
            var path = maybePath.get();
            if (!path.startsWith("/")) {
                throw new IllegalStateException("unexpected URL: " + path);
            }
            var nextPageUrl = URI.create(urlBase + path);
            System.out.println("The next page URL: " + nextPageUrl);
        }
    }

    public static void main(String[] args) {
        if (args.length == 0) {
            System.out.println("usage: java com.example.Demo ID");
            return;
        }
        var organizationName = args[0];
        try {
            run(organizationName);
        } catch (IOException | InterruptedException e) {
            System.out.println("failed (ignored)");
        }
    }
}

In this example, the result of "java com.example.Demo Microsoft" (that represents the one of parsing https://nuget.org/profiles/Microsoft/) will be as follows:

The next page URL: https://www.nuget.org/profiles/Microsoft?page=2

Note that each number represents the total downloads at that time.

🚧 The structure of the HTML that nuget.org generates is subject to change. This parser will follow such changes in future releases.
