Go has probably the most extensive stdlib of major languages outside of Python (happy to be corrected on that). You can get a sense for what is available by looking here: https://pkg.go.dev/std https://pkg.go.dev/std. There is also the "pseudo stdlib" that is maintained by the Go project but for one reason or another is not available in the stdlib currently: https://pkg.go.dev/golang.org/x https://pkg.go.dev/golang.org/x

No "outside of Python" qualifier needed.

Java seems to have just as much if not more available in its standard lib.

  Though some modern features are lacking, like a JSON parser or web server.
  - tazjin 4y ago
    It does contain several Javascript (!) interpreters, so you could probably glue those together as a JSON parser :)

    It does have a web server: https://openjdk.org/jeps/408 https://openjdk.org/jeps/408

      Does anyone actually use it? I’ve never even heard of this thing and I’m a professional Java dev
      - simiones 4y ago
        Given that it was only added in Java 18 and it is a simple static file server (no way to run custom code when serving a URL), I don't think it's in any way widely used at the moment. Edit: or will ever be. It is definitely explicitly not an equivalent of go's net/http. Indeed, there is probably never going to be an equivalent of net/http in the Java stdlib (since they prefer to rely on the user choosing one of the existing server frameworks, such as Jetty).
        philosopher1234 4y ago
        From your description it sounds like it is a completely different beast from net/http
        simiones 4y ago
        Yes, per the JEP that was linked, it is only intended as a toy server for quick example code, essentially: > Provide a command-line tool to start a minimal web server that serves static files only. No CGI or servlet-like functionality is available. This tool will be useful for prototyping, ad-hoc coding, and testing purposes, particularly in educational contexts. > It is not a goal to provide a feature-rich or commercial-grade server. Far better alternatives exist in the form of server frameworks (e.g., Jetty, Netty, and Grizzly) and production servers (e.g., Apache Tomcat, Apache httpd, and NGINX).

        The specific web server in the JEP is relatively new, but there has been an http server implementaion since 1.6: https://docs.oracle.com/javase/8/docs/jre/api/net/httpserver/spec/com/sun/net/httpserver/HttpServer.html https://docs.oracle.com/javase/8/docs/jre/api/net/httpserver...

        Cool, I had no idea about this. I see it's still available after the modularization effort, and it is: https://docs.oracle.com/en/java/javase/18/docs/api/jdk.httpserver/module-summary.html https://docs.oracle.com/en/java/javase/18/docs/api/jdk.https...

        It is tailored for the same purpose as Go's one, hello world.
        simiones 4y ago
        Go's net/http is essentially the only used Go HTTP(S) server. It is often wrapped with other libs to add things like request routing, but it is always used as the actual HTTP implementation. Not sure why you're saying its purpose is "hello world". The Java one is not usable in anything beyond hello world, and is explicitly not intended to be.
        pjmlp 4y ago
        The fact that is lacks any kind of administration console, and security integration with enterprise connectors shows it is at hello world level.
        simiones 4y ago
        As someone maintaining a pretty large networking industry proprietary app based entirely on net/http in terms of any kind of HTTP communication, I feel like I can easily tell you are wildly exaggerating. Admin consoles and enterprise connectors are entirely irrelevant to many uses of an HTTP server. Hell, even Kubernetes' API server is built using net/http.
        pjmlp 4y ago
        Yet many of those depend on having something like Apache, NGIX, HA Proxy, IIS,... taking care of the actual load.

Not as Java and .NET.
zendist 4y ago
.NET is a strong contender, I would say. The standard library is immensely useful, and many things you may wonder if you need are available as Nuget packages, coming from the same devs who build the std lib.

Go probably pales in comparison to .NET [0]. Its about 1 million APIs [0] https://apisof.net/ https://apisof.net/

Hell, I'll argue Go standard library is more extensive and better than Python's. Case in point: HTTP. The batteries included in Python definitely reflect the era of their creation.
