Yancy Yancy is a simple content management system (CMS) for administering content in a database. Yancy accepts a configuration file that describes the data in the database and builds a website that lists all of the available data and allows a user to edit data, delete data, and add new data. Yancy uses JSON Schema to define the data in the database. The schema is added to an OpenAPI specification which creates a REST API for your data. Yancy can be run in a standalone mode (which can be placed behind a proxy), or can be embedded as a plugin into any application that uses the Mojolicious web framework. Yancy can manage data in multiple databases using different backends (Yancy::Backend modules). Backends exist for Postgres via Mojo::Pg, MySQL via Mojo::mysql, and DBIx::Class, a Perl ORM Standalone App To run Yancy as a standalone application, you must create a "yancy.conf" configuration file that defines how to connect to your database and what the data inside looks like. See "CONFIGURATION" for details. NOTE: Yancy does not have authentication or authorization built-in. If you want to control which users have access to data, you should use an HTTP proxy with these features. Once the application is started, you can navigate to "http://127.0.0.1:3000/admin" to see the Yancy administration app. Navigate to "http://127.0.0.1:3000/" to see the getting started page. Rendering Content In the standalone app, all paths besides the "/admin" application are treated as paths to templates. The templates are found in the "templates" directory. You can change the root directory that contains the "templates" directory by setting the "MOJO_HOME" environment variable. Template names must end with ".format.ep" where "format" is the content type ("html" is the default). You can render plain text ("txt"), JSON ("json"), XML ("xml"), and others. Database content can be read by using the database helpers that Yancy provides. * "yancy->list( $collection )" - Get a list of items * "yancy->get( $collection, $id )" - Get a single item * "yancy->set( $collection, $id, $data )" - Update an item * "yancy->delete( $collection, $id )" - Delete an item * "yancy->create( $collection, $data )" - Create an item Some example template code: %# Get a list of people % my @people = app->yancy->list( 'people' ); %# Show a list of people names
    % for my $person ( @people ) {
  • <%= $person->{name} %>
  • % }
%# Get a single person with ID 1 % my $person = app->yancy->get( 'people', 1 ); %# Write the person's name to the page

Hi, my name is <%= $person->{name} %>.

More information about Mojolicious helpers is available at Mojolicious::Guides::Rendering. Mojolicious Plugin For information on how to use Yancy as a Mojolicious plugin, see Mojolicious::Plugin::Yancy. REST API This application creates a REST API using the standard OpenAPI API specification. The API spec document is located at "/api" in the standalone app, and "/yancy/api" in the Mojolicious plugin. INSTALLATION This is a Perl module distribution.
