all api calls happen only on the server so that api urls never appear in the browser s network tab under fetch or xhr when i use usefetch or useasyncdata with server true the request runs on the server during the initial load which is fine however when i navigate to another route and then return the data is fetched again from the client side and i can see the request url in the network tab i ve tried server true server apis and forcing ssr mode but none of them fully prevent client side re fetching how can i ensure usefetch or useasyncdata always execute only on the server even after route navigation while keeping all nuxt features like reactivity and loading states and without creating extra server api endpoints author blancer posted on 2025 10 13 categories javascript post

to avoid slow post redirect get prg flow when updating data i have two pages in my next js app entry detail user edits a single entry and clicks save entry list shows a list of all entries when the user saves from entry detail i want to do both of these atomically in one http request update the entry object in the database navigate to entry list and display the updated list of entries in a plain react express app i would do this put api entry server updates db server returns the full updated list of entries put that list into a client side entry store context redux zustand router push entry list entry list renders entries from the store no extra http request this achieves the behavior i want in a single http request one round trip avoiding a second request from entry list and improving ttfb ux question what is the idiomatic way to accomplish the same with next js is there a recommended pattern api route app router server action etc to update the entry return the updated list in the same response and navigate to entry list and render from the returned list without making a second http request author blancer posted on 2025 10 13 categories javascript should i start a requestanimationframe loop with an initial call to requestanimationframe callback here s my requestanimationframe callback function callback render requestanimationframe callback when starting an animation loop with this callback should i start the loop like this requestanimationframe callback or by simply calling the callback callback i get the feeling that if i start it by just calling callback then the callback will actually run twice in that initial frame resulting in a wasted call to render because it was called outside the requestanimationframe api is my assumption correct in other words if i just call callback by itself then there s a chance it would execute at the beginning of a frame and since callback internally schedules itself to run again before the next frame using requestanimationframe callback then the callback would just run again in the same frame author blancer posted on 2025 10 13 categories javascript no data or errors from server sent events i m new to
