Inspired on json-schema-validator for JAVA, the --fakeroot option, actually.

If you're validating some RAML (like me) then you should validate your JSON-schemas and examples also.

For this purpose I'm using ramlev which is using tv4, but you're encouraged to download any $ref manually before validating.

var tv4 = require('tv4'),
    refaker = require('refaker');

var data = { /* ... */ },
    schema = { /* ... */ };

refaker({
  schema: schema,
  fakeroot: 'http://example.com',
  directory: '/path/to/schemas'
}, function(err, refs, schemas) {
  if (err) {
    console.log(err);
  } else {
    for (var id in refs) {
      // register resolved refs
      tv4.addSchema(id, refs[id]);
    }

    // validates the first passed schema
    console.log(tv4.validateResult(data, schemas[0]));
  }
});

That's it.

• schema (object|aray)

  The JSON-schema to validate.

• schemas (object|array)

  Multiple JSON-schemas to validate at once.

  This is an alias for the schema option.

• fakeroot (string)

  If provided, any matching $ref will be resolved under the specified directory.

• directory (string)

  A local path containing the JSON-schemas.

  If missing, will use process.cwd() instead.

Any $ref found will be downloaded or faked locally.

The given callback will receive three arguments:

• err (mixed)

  Empty means success.

• refs (object)

  Hash of resolved $refs.

• schemas (array)

  Normalized schemas if success (same order as input).
