NAME

Dancer::Plugin::JSON::Schema - JSON::Schema interface for Dancer applications

VERSION

version 0.001

SYNOPSIS

use Dancer;
use Dancer::Plugin::JSON::Schema qw(json_schema);

post '/search' => sub {
  my $structure = param('q');
  my $result = json_schema('default')->validate($structure);

  # If you are accessing the 'default' schema, then you can just do:
  my $result = json_schema->validate($structure);

  ...
};

dance;

DESCRIPTION

This plugin makes it very easy to create Dancer applications that interface with JSON Schema.

It automatically exports the keyword json_schema which returns an JSON::Schema object.

You just need to configure where to get the schema from.

For performance, JSON::Schema objects are cached in memory and are lazy loaded the first time they are accessed.

CONFIGURATION

Configuration can be done in your Dancer config file.

Simple example

Here is a simple example. It defines one schema named default:

plugins:
  'JSON::Schema':
    default:
      schema: schemas/item.json

Multiple schemas

In this example, there are 2 schemas configured named default and accessories:

plugins:
  'JSON::Schema':
    default:
      schema: schemas/item.json
    user:
      schema: schemas/user.json

Each schema configured must at least have a schema option set.

If you only have one schema configured, or one of them is named default, you can call json_schema without an argument to get the only or default schema, respectively.

schema_info

Alternatively, you may also declare your schema information inside a hash named schema_info:

plugins:
  'JSON::Schema':
    default:
      schema_info:
        schema: schemas/item.json

alias

Aliases allow you to reference the same underlying schema with multiple names.

For example:

plugins:
  'JSON::Schema':
    default:
      schemas/item.json
    products:
      alias: default

Now you can access the default schema with json_schema(), json_schema('default'), or json_schema('products').

FUNCTIONS

json_schema

my $result = json_schema->validate( $structure );

The json_schema keyword returns a JSON::Schema object ready for you to use.

If you have configured only one schema, then you can simply call json_schema with no arguments.

If you have configured multiple schemas, you can still call json_schema with no arguments if there is a schema named default in the configuration.

With no argument, the default schema is returned.

Otherwise, you must provide json_schema() with the name of the schema:

my $user = json_schema('accessories')->select( ... );
