You can use $reduce (https://docs.jsonata.org/higher-order-functions#reduce) to find the first occurrence of an item. $reduce iterates over an array and passes an accumulator (the first index) as well as the current index and value. We can initialize the accumulator to -1 and if it is still -1 and the value matches the search, we return the index as the new accumulator value.

Once we have the index, we can use $filter (https://docs.jsonata.org/higher-order-functions#filter) to remove that index from the array:

Splitting the keys array should be achievable by accessing each element there by its index (given that the keyword and the URL are guaranteed to appear on the same index).

It looks like jsonata() expects a string expression as a parameter, which isn't explicitly stated in the docs, but is shown in the In Nodejs section.

You're using fs.statSync which is a synchronous function, meaning that every time you call it, all code execution stops until that function finishes. Look into using fs.stat (the asynchronous version), mapping over your array of filepaths, and using Promise.all.

Using the fs.stat (the asynchronous version) function, you can start the calls of many files at a time so that it overall happens faster (because multiple files can be loaded at once without having to wait for super slow ones)

Here's an example of what I mean, that you can run in the browser:

ANSWER

Answered 2021-Jan-25 at 17:23

The first part of your expression, payload{name:$average(price)} produces an object, not an array, so there is nothing to order. Remember that in JSON, an object is an unordered set of name/value pairs. If you want to create an ordered array of objects, similar to your input data, but aggregated as you've done, then you can use the following:
