Package jsonry exists to make is easier to marshal and unmarshal nested JSON into Go structures. For example: Can be marshaled and unmarshaled using the Go struct: There is no need to create intermediate structures as would be required with the standard Go JSON parser. JSONry uses the standard Go parser under the covers. JSONry is a trade-off that delivers usability in exchange for performance. JSONry uses struct tags to specify locations in the JSON document. When there is neither a "jsonry" or "json" struct tag, the JSON object key name will be the same as the struct field name. For example: When there is a "json" struct tag, it will be interpreted in the same way as the standard Go JSON parser would interpret it. For example: When there is a "jsonry" struct tag, in addition to working like the "json" tag, it may also contain "." (period) to denote a nesting hierarchy. For example:
