JSON Spec (Core)

JSON Spec is a tool for validation and generation of JSON data.

Describe specifications

Simple spec

If you give the test function to the spec function, the simple spec is created.

s.spec(x => x === 'spec');

And you can also give the regexp or an Array.

s.spec(/^\d+/);
s.spec(['a', 'b', 'c']);

Compose specifications

You can compose multiple specs.

and

s.and(x => !isNaN(Number(x)), x => x > 1000)

or

s.or(x => !isNaN(Number(x)), x => typeof(x) === 'string')

Validation

Using conform function can check wheather the given value conform the specification.

s.conform(x => );

Explain

An explain function outputs detail of specification violations.

s.explain(spec(x => typeof(x) === 'string'), 123);
