Different programs manage default application associations in unique ways. Command-line applications often use environment variables, whereas graphical applications typically utilize XDG MIME applications via APIs like GIO or Qt, or by calling <code>xdg-open</code>.

== Configuration ==
Using [[Home Manager]], this configuration example configures the handling of HTML-files and URLs by opening them with the browser LibreWolf. Replace <code>myuser</code> with the name of your low-level user.<syntaxhighlight lang="nix">
home-manager.users.myuser = {
xdg.mimeApps = {
enable = true;
defaultApplications = {
"text/html" = "librewolf.desktop";
"x-scheme-handler/http" = "librewolf.desktop";
"x-scheme-handler/https" = "librewolf.desktop";
"x-scheme-handler/about" = "librewolf.desktop";
"x-scheme-handler/unknown" = "librewolf.desktop";
};
};
};
</syntaxhighlight>In case a program is missing a .desktop-file, the following example adds a <code>librewolf.desktop</code> file to the MIME database with the specific binary path.<syntaxhighlight lang="nix">
home-manager.users.myuser = {
xdg.desktopEntries.librewolf = {
name = "LibreWolf";
exec = "${pkgs.librewolf}/bin/librewolf";
};
};
</syntaxhighlight>

== Usage ==
Try opening a web page with <code>xdg-open</code> which is part of the package <code>xdg-utils</code><syntaxhighlight lang="shell">
xdg-open "https://nixos.org"
</syntaxhighlight>
