Expose a method to get the cache? about sswr HOT 20 CLOSED

I would like a method like: getKeyStartsWith(key: string) to find for example keys like: /players?page=1.

And then I can search values for the playerId I need in detail page.

What do you think?

You've got:

https://github.com/ConsoleTVs/sswr/blob/master/src/index.ts#L105

and

https://github.com/ConsoleTVs/sswr/blob/master/src/index.ts#L115

from sswr.

It works. But.

As I said I'm using it for a "classic" list/detail and here what happens:

1. I'm on the /players list page
2. I have fetched data with /players key
3. I move on the /players/1 detail page
4. On detail page I use get("/players") to populate my initialData to speed up UX
5. BUT during this navigation from /players to /players/1 the key /players is refetched in background hence the get("/players") does not return data, only a Promise, useless in this case

But if I need a Promise I can use getOrWait() instead.

So I think we should not "change" the cache during refetching because we need to get() something even if is stale.

What do you think?

I think we need a method like getStartingWith(key: string).

Why not just use the mutate to populate other keys or just use useSWR with revalidation set to false? There is a bunch of options you can pass to it!

Why not just use the mutate to populate other keys

I cannot, because I'm checking for data already in cache during new fetch...

or just use useSWR with revalidation set to false

The players list is refetching because I'm using a variable, and it can depends on other usecases.

Cannot be this the solution.

What you are trying to achieve is probably not possible.

1. You are fetching the endpoint for /players and retrieve one(!) object (most likely parsed from a json-string)
2. You are navigating to /players/1 and want the cache to know which part of the data in the cache belongs to player with id 1. Problem is that this information isn't retrieved by the cache.

To achieve such behaviour you could either:
a) parse your one object on the first fetch and populate the cache with individual objects
b) use graphql which has such features because of fragments and strong typing on both ends (f.e. with urql's graphcache).

But there is no way to get this for free. You have to type and/or parse your data at some point.

from sswr.

It's possible.

I'm getting the players object which is like this:

{ players: [{id: "1", name: "Name"}, ...and others] }

and with a .find() I can find my player/1.

from sswr.

It's doable right now with svelte-query.

from sswr.

{ players: [{id: "1", name: "Name"}, ...and others] }

Just find the player with id = 1 and put it in the cache:

mutate('player/1', {id: "1", name: "Name"})

from sswr.

Just find the player with id = 1

This is what I'm asking you!

If I use get() and the query is re-fetching I cannot find players (already fetched before) because I get a promise!

from sswr.

mutate or initialData is not a problem!

from sswr.

You have to change step 4 from your list.

• I'm on the /players list page
• I have fetched data with /players key
• I populate the cache /players/${id} for each fetched player using mutate()
• I move on the /players/1 detail page
• UX will first show the stale / cached data while it re-validates it in the background.

from sswr.

I populate the cache /players/${id} for each fetched player using mutate()

But I don't know if a use will need this.

I'm opening a new page and in background the previous list is refetching (for many reasons).

This is not a valid solution.

from sswr.

How would this be done in https://swr.vercel.app otherwise?

from sswr.

I don't know, But it's doable in this project, the problem is we need to swap the data for that key only when the promise is resolved, not before.

IMO.

IMHO:
a) your sentences make no sense, are incomplete, plain false or simply not understandable.
b) no github-repo is your personal support-forum
c) "This is what I'm asking you!"? Are you nuts or simply rude? @ConsoleTVs provides a lib, developed in his freetime, free of charge, he even provides support and you dare to demand anything? Be grateful and nothing else. Period.
d) I'm out. I'll no longer answer questions or similar by you.

@benbender I love you. 😄

from sswr.

My verdict has fallen: you are plainly arrogant. For no obvious reason. #kthxbye #block

from sswr.

I really don't understand your behavior, @benbender.

Did you block me simply because I told you I love you? To avoid replying and wasting your time reading a reply to a useless message you wrote.

A message that doesn't make sense: I wasn't "demanding" anything from @ConsoleTVs; and among other things, as you well know and as @ConsoleTVs can tell, I am helping and collaborating with various PR on this splendid project.

You did not understand my question and you get angry, it seems like childish behavior to me.

Grow, live and let live.

Lots of little kisses.
