API

jsonkvs(path, config)

Load a JSON file at a given path.

.get(key)

Get the value of a given key. If no key is passed will return the whole object.

.set(key, value | patch, replace=false)

Set the value of a given key. Can be called two ways:

• By passing the key as first argument and value as second.
• By passing an patch object. In this case the patch will be merged. If replace is set then the original file will be overridden by the patch

.del(key)

Unset a given keys

.save()

Commit changes to disk

ToDo

• [ ] When a file is open it's contents is loaded into memory and it's not locked.
• [ ] If the file changes on the FS it's contents should be reread and memory copy updated.
• [ ] Any pending changes in memory will superseed new changes from disk.
• [ ] The above bollocks should all be configurable (you can lock a file, get/set directly from the file (via inmemory cache), conflict resolution)
• [ ] Can save to an alternative location
