Diff and patch for JSON in Elixir, works really well and is really fast
First, add JsonDiffEx to your mix.exs dependencies:
def deps do
[{:json_diff_ex, "~> 0.5.0"}]
endThen, update your dependencies:
$ mix deps.getSimple example:
JsonDiffEx.diff %{"test" => 1}, %{"test" => 2}
#=> %{"test" => [1, 2]}Now with list:
JsonDiffEx.diff %{"test" => [1,2,3]}, %{"test" => [2,3]}
#=> %{"test" => %{"_0" => [1, 0, 0], "_t" => "a"}}Now with a map in the map:
JsonDiffEx.diff %{"test" => %{"1": 1}}, %{"test" => %{"1": 2}}
#=> %{"test" => %{"1": [1, 2]}}Now with a map in an list in the map:
JsonDiffEx.diff %{"test" => [%{"1": 1}]}, %{"test" => [%{"1": 2}]}
#=> %{"test" => %{"0" => %{"1": [1, 2]}, "_t" => "a"}}Simple example of a patch:
JsonDiffEx.patch %{"test" => 1}, %{"test" => [1, 2]}
#=> %{"test" => 2}Now a patch with list:
JsonDiffEx.patch %{"test" => [1,2,3]}, %{"test" => %{"_0" => [1, 0, 0], "_t" => "a"}}
#=> %{"test" => [2,3]}Now a patch with a map in the map:
JsonDiffEx.patch %{"test" => %{"1": 1}}, %{"test" => %{"1": [1, 2]}}
#=> %{"test" => %{"1": 2}}Now with a map in an list in the map:
JsonDiffEx.patch %{"test" => [%{"1": 1}]}, %{"test" => %{"0" => %{"1": [1, 2]}, "_t" => "a"}}
#=> %{"test" => [%{"1": 2}]}Should work with jsondiffpatch and the test cases currently test make sure we keep that compatibility.
