Diff Dataset Fields

Compare items of two datasets to see changes in their fields. You match the items by a key field and then compare the any number of textual fields. ## Diff You can choose one or more fields to diff between two items that are matched by a key field. The diff is computed using the fast-diff package where the output is a list of text parts that are marked with a number depending if they are inserted (1), deleted (-1) or unchanged (0). ## Output The output is a JSON object with the following properties: - type: Representing how the items were compared. Can be new, removed, unchanged or updated. - oldItem: The item from the old dataset - newItem: The item from the new dataset - diff: The diff between the two items. Only present if the type is updated. ### Example input json { "oldDatasetId": "0Azg4BxggC3RmcPpY", "newDatasetId": "i4mfnrQEP8QmQAbHu", "fieldToMapBy": "url", "fieldsToDiff": ["text", "markdown"], "outputTypes": ["new", "removed", "updated", "unchanged"], } ### Example output This is one item that was matched in both datasets, the real output will have all items from both datasets. json { "type": "updated", "oldItem": { "url": "https://www.peacocktv.com/start", "text": "PeacockAdobe AudienceManagerBack ButtonSearch IconFilter Icon\nEnter your email to get started", "markdown": "# PeacockAdobe AudienceManagerBack ButtonSearch IconFilter Icon\n\n## \n\nEnter your email to get started", }, "newItem": { "url": "https://www.peacocktv.com/start", "text": "PeacockBack ButtonSearch IconFilter Icon\nEnter your email to get started", "markdown": "# PeacockBack ButtonSearch IconFilter Icon\n\n## \n\nEnter your email to get started", } , "diff":{ "text": [ [ 0, "Peacock" ], [ -1, "Adobe AudienceManager" ], [ 0, "Back ButtonSearch IconFilter Icon\nEnter your email to get started" ] ], "markdown": [ [ 0, "# Peacock" ], [ -1, "Adobe AudienceManager" ], [ 0, "Back ButtonSearch IconFilter Icon\n\n## \n\nEnter your email to get started" ] ] } }
