 ### Store queries in Redux
 
-Gatsby is now in the [handleQuery](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/query/query-watcher.js#L54) function.
+Gatsby is now in the [handleQuery](https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/query/query-watcher.ts#L80) function.
 
 If the query is a `StaticQuery`, Gatsby will call the `replaceStaticQuery` action to save it to the `staticQueryComponents` namespace which is a mapping from a component's path to an object that contains the raw GraphQL Query amongst other things. More details can be found in the doc on [Static Queries](/docs/static-vs-normal-queries/). Gatsby also removes a component's `jsonName` from the `components` Redux namespace. See [Page -> Node Dependencies](/docs/page-node-dependencies/).
