Make Nix Derivation

Making a nix derivation typically includes following steps.

1. Choose a derivation function: pkgs has some wrapper functions of mkDerivation for different frameworks. See:Languages and Frameworks

• mkDerivation is a wrapper of derivation function.

2. Find a source: where the source code come from? github repo or tarball or any other available from url.

• If the source is precompiled, should set a appropriate value for meta.sourceProvenance. See: Source provenance

3. Choose a fetcher: use a appropriate fetcher to download the source. See Fetchers
4. Generate lock file: if you'd build from source, this might require a lock file so nix can download dependencies during build.

• If the source is precompiled, this is probably not necessary.
• Lock file is typically required when using a wrapper function of mkDerivation for certain framework.
