Absinthe Sorting Codec

Convert the JSON output of an introspection query into a deterministic ordering of types (sorted by name). This results in saner diffs when committing schemas to version control.

Standalone

Can convert the output of introspection queries in JSON format to a sorted, deterministic ordering of types. See the test fixtures.

Example

AbsintheSortingCodec.encode!(Jason.decode!("swapi.json"))

Absinthe

Can be used to convert an Absinthe schema to a deterministic format by using AbsintheSortingCodec as the JSON encoder.

Example

mix absinthe.schema.json --schema MySchema --json-codec AbsintheSortingCodec --pretty

NOTE: If the mix command gives the following error --

(Argument Error) you atttempted to apply :module on "AbsintheSortingCodec". If you are using apply/3, make sure the module is an atom. If you are using the dot syntax, such as map.field or module.function, make sure the left side of the dot is an atom or a map

-- you need to upgrade to Absinthe 1.4.14 or 1.5 or later.
