Removal of app.postConfigure

Due to the restructuring of the Context class we remove the deprecated app.postConfigure() construct. Now you are able to even hook into the core boot process more deeply. With the help of Context.preConfigure() and Context.postConfigure() you can easily port your application to fit the new needs.

The 0.7 code base

BlogContext.prototype.configure = function(app, server, callback)
{
    // [..]

    // Setup post configure hook
    app.postConfigure = function(app, server, callback) {

        // Add 404 error handler
        // Add error handler middleware
        // Do other post configure stuff

        callback && callback();
    };

    // [..]
};

The 0.8 code base

BlogContext.prototype.configure = function(app, server, callback)
{
    // [..]
};

/**
 * Worker context post configure method.
 *
 * @param {Object} app - The application object
 * @param {Object} server - Server object
 * @param {Function} callback - Function to call on finish
 */
BlogContext.prototype.postConfigure = function(app, server, callback)
{
    // Add 404 error handler
    // Add error handler middleware
    // Do other post configure stuff

    callback && callback();
};

Wildcard loading of helpers

Greppy 0.8 supports real wildcard loading of helpers. With support for inner and end of path wildcards and globstars. The new implementation supersedes the poor implementation of 0.7 where we only support wildcarding on the end of a path which acts more like the new globstars. With the help of this new feature you will be able to skip big and complicated manual walking through results of greppy.helper.list() to filter helpers equivalently.

The 0.7 code base

var map = greppy.helper.get('renderer.meta.*');
// {
//     "author": {},
//     "description": {},
//     "expires": {},
//     "robots": {},
//     "provider.google.robots": {},
//     "provider.google.site-verification": {},
//     "provider.bing.robots": {},
//     "provider.google.site-verification": {}
// }

// Not supported in 0.7
var map = greppy.helper.get('renderer.meta.**');
var map = greppy.helper.get('renderer.meta.provider.*.robots');
var map = greppy.helper.get('renderer.**.google.*');
var map = greppy.helper.get('renderer.**.google.site-verification');

The 0.8 code base

• A wildcard (*) will match all helpers on the first level
• Globstars (**) will match all helpers on any level
• The result will be a flat or deep hash
• We strip the prefix of the paths until we reach the first asterisk

var map = greppy.helper.get('renderer.meta.*');
// {
//     "author": {},
//     "description": {},
//     "expires": {},
//     "robots": {}
// }

var map = greppy.helper.get('renderer.meta.**');
// {
//     "author": {},
//     "description": {},
//     "expires": {},
//     "robots": {},
//     "provider": {
//         "google": {
//             "robots": {},
//             "site-verification": {}
//         },
//         "bing": {
//             "robots": {},
//             "site-verification": {}
//         }
//     }
// }

var map = greppy.helper.get('renderer.meta.provider.*.robots');
// {
//     "google": {
//         "robots": {}
//     },
//     "bing": {
//         "robots": {}
//     }
// }

var map = greppy.helper.get('renderer.**.google.*');
// {
//     "meta": {
//         "provider": {
//             "google": {
//                 "robots": {},
//                 "site-verification": {}
//             }
//         }
//     }
// }

var map = greppy.helper.get('renderer.**.google.site-verification');
// {
//     "meta": {
//         "provider": {
//             "google": {
//                 "site-verification": {}
//             }
//         }
//     }
// }
