How many web apps can you name that don’t rely on any external gems? Packaging that mess is a pain in every scripting language.

  Anything that runs on JRuby can be packaged as a single file.

    And even with MRI, it's not as painful as people make out. Set `$GEM_HOME`, `bundle install`, tar up your app and the gems, stick them on the server.

  How far do you make it writing a web app in rust or go without pulling in external packages, then? Or a front-end using only javascript and html?
  • steveklabnik 8y ago
    In Rust, it’s pretty quick. You could write a server yourself, but it would take a lot of work. It’s trivial with a package though.

      Steve, what is Rust's equivalent to Go's cross-compilation-- plain old cargo build?

          Thank you
          • steveklabnik 8y ago
            Note that you also may want to use xargo or cargo-xbuild to build other custom targets, and rustup to fetch the stdlib for the targets listed above.
            • crzwdjk 8y ago
              Aren't there also linker issues with cross-building for some targets like i686-pc-windows-msvc? At least, I don't think I ever got it to work properly but I don't recall what the exact problem was.
              • steveklabnik 8y ago
                Some platforms are harder than others, it’s true. And if you link to any C code, you have to deal with that as well. As an example, I just saw this: http://zork.net/~st/jottings/rust-windows-and-debian.html http://zork.net/~st/jottings/rust-windows-and-debian.html We’ll get there!

    I never use server-side external packages when writing web apps (well, except the bcrypt crypto package, which is an official package but not technically part of the stdlib yet). Dependencies are evil.
