Static vs Normal Queries

TODO Difference between normal and Static Queries

Static Queries don’t need to get run for each page. Just once

staticQueryComponents

Started here because they’re referenced in page-query-runner:findIdsWithDataDependencies.

The redux staticQueryComponents is a map from component jsonName to StaticQueryObject. E.g

{
  `blog-2018-07-17-announcing-gatsby-preview-995` : {
    name: `/path/to/component/file`,
    componentPath: `/path/to/component/file`,
    id: `blog-2018-07-17-announcing-gatsby-preview-995`,
    jsonName: `blog-2018-07-17-announcing-gatsby-preview-995`,
    query: `raw GraphQL Query text including fragments`,
    hash: `hash of graphql text`
  }
}

The staticQueryComponents redux namespace is owned by the static-query-components.js reducer with reacts to REPLACE_STATIC_QUERY actions.

It is created in query-watcher. TODO: Check other usages

TODO: in query-watcher.js/handleQuery, we remove jsonName from dataDependencies. How did it get there? Why is jsonName used here, but for other dependencies, it’s a path?

Usages

• websocket-manager. TODO

• query-watcher.

  • getQueriesSnapshot returns map with snapshot of state.staticQueryComponents
  • handleComponentsWithRemovedQueries. For each staticQueryComponent, if passed in queries doesn’t include staticQueryComponent.componentPath. TODO: Where is StaticQueryComponent created? TODO: Where is queries passed into handleComponentsWithRemovedQueries?
