I am working on designing a timesheet Lightning Web Component for my company. Internally, we use a sObject that tracks individual sessions, which then gets rolled up one way to generate payroll, and another way to create invoices. To that end, we don't have a timesheet sObject in our schema (we do have a paystub sObject, but we run payroll every two weeks and collect timesheets every week).
The general flow of what needs to happen is run a SOQL query, transform the data into rows (clients) and columns (dates), and then display the data for viewing and editing. The SOQL clearly happens in an Apex class, and the display is clearly happening in an LWC, but I am unclear about the transformation stage. Would it make sense to have an Apex class gather all the data, transform it, and then @wire the data to the LWC row by row? Or should I just use the Apex class to generate all of the data, @wire a list to the LWC, and use Javascript objects to sort everything into rows and columns?

If I had to design this, I would have created a wrapper class to collect all data within the Apex and then return theList<MyWrapperClass>to the LWC. This way I would keep all the logic of fetching/transforming/saving data consolidated at one place.

Unless the transformation significantly reduces the amount of data you have to send from the server to the client, it most likely makes sense to do as much as possible in the client (JavaScript). JavaScript is far more efficient in CPU time than Apex, so you'll reduce the overall time the user has to wait for the results to appear. Also, if you decide you later want to provide different options (filtering, sorting, etc), you can avoid network activity entirely by using JavaScript as much as possible, allowing near-instant updates to the page.

Adding color to this discussion: ES6.map(),.filter()and.reduce()significantly improve UX at the expense of server-side reusability. You can still offload any helpers to a LWC utils file and find client-side reusability there.
