Download shesek's github spark-npm.tgz, verify signature, unpack
spark-npm.tgz, patch package.json to include qrcode-terminal in
dependencies, run node2nix with tmpdir as local source, replace tmpdir
spark-wallet source with shesek's github spark-npm.tgz in
node-packages.nix.
spark-wallet: erikarvstedt fixups
This is almost equivalent except that with symbolic reference node2nix
consults the NPM registry for package.json information instead of the
package.json in the tgz file. The registry canonicalizes the
"dependencies" attribute in that it adds all "optionalDependencies",
which the npm binary would do for local package.json files, but
node2nix does not.
For spark-wallet optionalDependencies are not listed in the tgz
distributed package.json, hence node2nix misses them. This leads to a
missing qrcode-terminal package and spark-wallet dying when called
with -Q.
The strategy of invoking node2nix inside a derivation (installPhase in
this case) does not work, as under NixOS installations there is no
network traffic allowed during a derivation build. Hence, we move
node2nix outside and rewrite the packaging into the modules.
Also switch to callPackage instead of plain imports. This could
probably be done on all other imported packages inside of
nix-bitcoin-pkgs.nix.
