New Publish API

[jonwinton]

Summary

Adds two options to a site's controller around publishing:

• resolvePublishUrl: An Array of functions that will be used in a Promise Chain. One of the functions should return a url that the page should be published to.

• modifyPublishedData: An Array of functions that are reduced through after a page's url has been determined, this allows you to modify the page data before publishing is complete.

Example

module.exports.resolvePublishUrl = [
    // canonical URL
    (uri, data, locals) => publishing.getCanonicalUrl(data, locals, mainComponentRefs),
    // evergreen articles
    (uri, data, locals) => publishing.getSlugUrl(data, locals, mainComponentRefs),
    // regular dated articles
    (uri, data, locals) => publishing.getYearMonthSlugUrl(data, locals, mainComponentRefs)
];

module.exports.modifyPublishedData = [
  publishing.addLastModified
];
