• history@3 uses query-string@4.2.2 to provide the default querey string parsing. see:

  • https://github.com/ReactTraining/history/blob/314ce46f31f91e45a68e2f6d29cb974afc606842/modules/useQueries.js#L24

  • https://github.com/ReactTraining/history/blob/v3/docs/QuerySupport.md

  • https://github.com/ReactTraining/history/blob/314ce46f31f91e45a68e2f6d29cb974afc606842/package.json#L26

• In terms of the types I'm using: https://github.com/sindresorhus/query-string/blob/master/index.d.ts#L92-L94

• The API in query-string@4.2.2 matches the types: https://github.com/sindresorhus/query-string/tree/v4.2.2#api

For context, I'm helping migrate sentry to typescript (https://github.com/getsentry/sentry), and I'm updating the types upstream on history@3, which will hopefully propagate to react-router@3.
