+ Pinning Inputs with Mirrors

+ Mirrors are a very good idea for project to have. +

+
+ Increases project resiliance as all servers go down so ideally something should be online to fallback to +
+
+
+ Helps accessibility as some regions block users based on sanctions & others might not agree to the terms of service or privacy laws in the jurisdiction of some options +
+
+
+ If self-hosted, then you/your project owns the codeâââwhich can help with potential censorship +
+

+ At the time of writing, Nix flakes does not & cannot support mirrors in input pinning requiring an input pinner like Nixtamal to automate it. +

+ How to pin a repository with mirrors in Nix + Nixtamal +

+ Mirrors are not supported on all kinds (fetcher limitations) however these can be supported: +

+
+ File +
+
+
+ Archive +
+
+
+ Darcs +
+
+
+ Pijul +
+
+
+ Git (only in eval time fetching using builtins.fetchGit) +
+

+ Letâs show the way using the Soupault repository, but if itâs one of the supported kinds, any will work. +
