…ion (aka Ludicrous Mode) (#4555) * Create placeholder JSON store * Rename * Websocket placeholder * Push query results JSON over websockets * More descriptive variable name * Fix queries being overwritten * Remove eslint-disable flag * Remove junk * test require error fix for windows * dont require json data in sync-require * dont add layout data to json array multiple times * initial async loading * revert saving json directly to public for now * updated production-app to sync with prop name change in ComponentRenderer * we load json data via json-loader component in develop and not handling it with webpack import/require * hashes for json files * fix preloading, use xhr instead of fetch - for some reason can't force fetch to not create additional request, with any `cache` or `mode` configuration * dont use full paths in dataPath - remove static/d/ path and .json ext - results in smaller app bundle especially with large ammount of pages * Enable cached query results to be loaded * Don't dump all query results out to the client Instead only push results out if the data is for a path that's currently being viewed in a client. * fix preload link to json data * remove not used function * remove more not used code * Update to latest webpack/mini-css-extract-plugin * don't write new (a)sync-requires.js if components didn't change (#4759) * create just one websocket client (#4763) * Filter out duplicate query jobs and create secondary queue for jobs if path already has query in flight * [json-loader] Don't emit new file node until previous is finished processing (#4785) * Don't emit new file node until previous is finished processing This is an experiment to use [xstate](http://davidkpiano.github.io/xstate/docs/#/) to setup state machines to better handle complex state changes as we sometimes have. Ideally this happens in core and then gatsby-source-filesystem just has a simple queue and emits a new file node every time the system returns to idle. In a future refactor we'll do that plus refactor other parts of core that should be handled in a state machine e.g. pages-query-runner.js This PR also reinforced the need for us to implement [tracing](https://github.com/jaegertracing/jaeger) in core / plugins as that'd make it far far easier to understand what's happening and when. * Document state machine and remove extraneous Chokidar states * Remove console.log * [json-loader] Only log file events if we're past bootstrap (#4826) * Don't emit new file node until previous is finished processing This is an experiment to use [xstate](http://davidkpiano.github.io/xstate/docs/#/) to setup state machines to better handle complex state changes as we sometimes have.

This sort of thing will be much easier to debug with tracing support. * Add initial forward slash * Actually this is how we add back the initial forward slash
