Browse files Browse the repository at this point in the history
* page-data loader working for production-app

* get new loader.getPage stuff working with gatsby develop

* fix static-entry.js test

* remove loadPageDataSync (will be in next PR)

* use array of matchPaths

* Deprecate various loader methods

* remove console.log

* document why fetchPageData needs to check that response is JSON

* in offline, use prefetchedResources.push(...resourceUrls)

* root.js remove else block

* loader.js make* -> create*

* loader drop else block

* pass correct path/resourceUrls to onPostPrefetch

* s/err => null/() => null/

* Extract loadComponent from loadPage

* remove pageData from window object

* update jest snapshots for static-entry (to use window.pagePath)

* add loadPageOr404

* preload 404 page in background

* normalize page paths

* comment out resource-loading-resilience.js (will fix later)
