schemacrat

Validate 1 or more json documents against one of many schemas based on the describedBy field in the document

returns exit code of 1 if any of the passed json files fail and prints errors to stderr

Schema index

We need an index of schemas to validate against. By default we will try to read this from cwd/schema. The expected format is

{
    default: {"A valid": "json schema"},
    someIdentifier: {"Another valid": "json schema"}
}

Only the default schema is required.

An alternate location for the schema can be specified using the environment var SCHEMA_SOURCE. We suggest passing this as an absolute path.

A document with a top level describedBy is validated against the matching schema from the index or the default schema if it is not found.
