json-derulo

A library to maintain JSON files that follow a strict structure

function sortJsonFile(jsonFile, sortField, sortDirection)

This will sort a JSON file based on what key you want sorted. The key to be sorted one MUST be of String or Number value, otherwise. An error will be thrown. This will return a promise with a stringified JSON object with your sorted JSON as well as your JSON file being sorted.

You can now sort either ascending or descending. pass in 'ASC' for ascending or 'DESC' for descending. If nothing is passed in, it will default to descending.

function findAllDupes(jsonFile, key)

This will find every duplicate in your JSON file based on the key value. That is passed in. This will return an array of the dupes.

function removeDupe(jsonFile, dupeField, dupeValueToRemove)

This will remove a dupe from a JSON value based on the key field, as well as the value relating to that key that is a dupe. An error will be returned if the value cannot be found or if there is no duplicates. This will rewrite the file with the dupe removed and return a promise with a stringifed JSON object with the dupe removed.

function removeAllDupesForKey(jsonFile, key)

This will find every single possible duplicate for a key and remove them all. This returns a promise with a stringified JSON object with all the dupes missing as well as your JSON file overwritten with no dupes. Will return an error if no dupes are found.

Plans for the future

• Add function to Remove All Dupes
• Allow for more sorting options rather than string & int
• Add ability to select what dupe to remove for user
• Potentially create a CLI tool for this
