aeson-schema is an implementation of the JSON Schema specification. It can be used in two ways:
- To validate JSON value against a schema.
- To generate a parser for a schema. The generated code includes Haskell data structure definitions and FromJSON instances. This allows you to use the validated data in a type-safe and convenient way.
You can install this library using cabal:
cabal update && cabal install aeson-schema
Running the tests
aeson-schema utilizes the cabal sandbox. To get up and running with the tests you'll need to use these commands:
cd aeson-schema git submodule init git submodule update cabal sandbox init cabal install cabal install --enable-tests cabal test
aeson-schema implements Draft 3 of the spec. It supports all core schema definitions except the following 'format' values:
I would be happy to accept pull requests that implement validation of one of these formats, fix bugs or add other features.
