Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/43340 Adds convenience methods `jsonResult`, `jsonError` and `jsonNotification` for more ergonomic construction of CDP JSON responses. Note that CDP is *loosely* based on [JSON-RPC 2.0](https://www.jsonrpc.org/specification), but differs for example in the omission of `"jsonrpc": "2.0"`. Before: ``` frontendChannel_(folly::toJson(folly::dynamic::object("id", req.id)( "error", folly::dynamic::object("code", -32602)( "message", "executionContextName is mutually exclusive with executionContextId")))); ``` After: ``` frontendChannel_(cdp::jsonError( req.id, cdp::ErrorCode::InvalidParams, "executionContextName is mutually exclusive with executionContextId")); ``` Changelog: [Internal] Reviewed By: motiz88 Differential Revision: D54202854 fbshipit-source-id: 76a407ae39ff9c2ec79bcaddb6cd4d494afb7693
