Sometimes we need to write a lot of json files. They may have lots of similar parts, so I came up an idea to use json-t reduce the unnecessary repetition. Extending json language with two simple concepts.
$extend is used as a json object's key.
The value of $extend is a string that contains a path to another configuration file to inherit from.
The path may use Node.js style resolution.
Json from the base file are loaded first, then overridden by those in the inheriting config file. Overridden happen on the top-level properties. All relative paths found in the configuration file will be resolved relative to the configuration file they originated in.

pipe with jmespath
JMESPath is a query language for JSON.
It is integrated in $extend. Use | after the file path to manipulate json.

- json-t only add two new concepts
- you can use your own json editor to edit your template files
- recommend keeping .json as suffix file name (get json highlight), but appending
-tto the original filename. - learn about https://jmespath.org/
