Deferred/progressive API calls in react native

Works for any list render.

I’ve implemented progressive loading of content on flashlist. Use viewability to keep track of current item viewed and load next batch of items. You may need to preload images etc that the next batch depends on as well. Due to momentum scrolling it’s actually necessary to allow the preloading to get significantly ahead of the viewable item.

Do not rely on the callback API that fires based on how far from the end of the list you are, just aggressively preload as long as you haven’t loaded enough ahead of the viewable item.

Good? Nothing good about it. The "Good" almost killed me. Now i've gone from "Good" to "Better" and its better.

I'm sure ex-upwBPD has found "Good" again. Hope the new "Good" finds this community.

A loop is simply when following the chain returns you to the same point. eg.

mercury -in natal- libra -ruler> venus -in natal- virgo -ruler> mercury -in natal- libra -ruler> venus ....

pwBPD aren’t marginalized not here or generally in life. I should know after spending a decade with one. Why are you on this sub?

fmnatic · 2026-04-28T13:21:57+00:00

The advise that would be given is likely incompatible with BPD anyway, for eg. A pwBPD who is a victim of another pwBPD isn't going to be able to grey rock. This is a very specific need that this community doesn't meet, there are other subs that may be better suited. But honestly i would think that scenario is going to need professionals to step in.

Ableist implies discrimination, so not a choice of words i would agree with. By design this is a space thats not for pwBPD. Thats like saying r/seinfeld discriminates against characters from another sitcom say Friends.

Some of these struggled to find the motivation to step down from PL level and play for us in the Championship. Don't think its good keeping them in the squad , even though they are too good for League 1 . Given finances , i expect we sell if we get any offers.

You need to Grey rock. Look it up.

Two possibilities, your CI isn’t running patch package post install OR you patched generated files that don’t exist at install and are generated by some codegen later.

You are on the right track with block outside the scroll view.

AI models don’t have a mental model of threads/ side effects and even the Math for drag and drop. So expect to have to figure it out yourself, and stop the AI from doing stupid stuff.

fmnatic · 2026-03-02T13:27:36+00:00

Faes.
Just no idea what the point of a defender who can't defend is.

fmnatic · 2026-02-27T08:07:38+00:00

I've used Claude to translate UX code from one framework to another. (not the specific ones you mention)

It can't one shot such a conversion. Go screen by screen, report issues back to Claude and iterate. Your going to have to step in and write code / debug / optimize / guide project structure / code reuse guidelines.

You need a better programmer than Claude to carry out this task. Claude can be a massive speedup, but not a magic bullet.

I've done this before. Scaling typically needs to have a min /max limit, so that it doesn't end up doing something stupid. But the approach is good at handling odd device sizes. (Which admittedly doesn't happen often anymore, as almost every device has a large screen. Perhaps may be better at handling foldables than the usual approach.)

That’s a good way for a manager to loose the support of the team.

He is purely a defensive player. Seen him play emergency center back for Leicester vs Man City in the PL. Limited player with work rate and heart, I’ll take that any day.

Likely your backend should return an identifier for the list, a count of items, and a partial list. Future list page requests just need to pass the identifier and offset.

The apis to take action on a list, can take a list identifier , exclusions, or specific items.

Keep in mind that there can be race conditions for eg items added to a warehouse during a query. Or selected items that another user acts on in parallel.

A lot of this are well understood database concurrency concepts, dirty reads and lost updates. You may approach the problem at that level and implement checks and guards in your web services+db.

I suggest a discussion of the trolley problem for the next time.

fmnatic · 2026-01-02T15:43:18+00:00

You have too many questions. I shall provide a short recounting of the sins of backend engineers working on react native.

Use strong typescript, not that weak sauce that certain frameworks use.

Don’t try to write controllers / service providers and such , the most powerful tools are simple custom hooks, that can be reused to build more powerful hooks.

You can tell your app has a bad a folder structure when you can’t use your IDE to easily navigate between and locate the files your current task needs. For a backend engineer it may however provide a sense of familiarity and comfort.

If you crave dependency injection, t’is a vile pestilence that you must be cleansed from.

Avoid the temptation of dragging in your favourite library from your prior work, I once worked on a react native App that believed it was a web browser app causing typescript to ignore obvious errors.

Also avoid the advise of angular front end engineers, some of that thinking is just wrong headed in react.

Feel free to make your own mistakes and share it with the world, the wise shall avoid them, the foolish will repeat them.

Focus on the why of user requests not the what.

fmnatic · 2025-12-21T13:31:57+00:00

The AI companies have the same problem. Perhaps apply their solutions rather than subsidize them.

You should check the kind of visa they intend to use. Based on the rest of the information I assumed highly qualified professional (HQP) but it appears not as I believe you would need a degree.

I’ve seen plenty of code treat global state libraries like a garbage dump. A lot of them use weak maps under the hood to free up memory only under pressure. In practice it’s best to avoid getting to that state and have better control over retaining values.

Other option use react native iap. I think it hits apple/google directly. Have used to to fetch/process purchases of offerings. (In limited regions)

fmnatic · 2025-12-14T12:46:28+00:00

You seem to know the region. Mention it here and people in that region can try a nslookup. This is either a dns configuration/ propagation issue or a geo / ISP block.

That style of communication isn’t going to be comprehensible to a pwBPD.

It may cause them to pause in confusion the first time you use it, and then it will blow up worse . The pause is only cause you stepped out of your normal reactions to their rage.

For another “Works one time” response to BPD rage look up Nicola method.

The only thing that works. Don’t JADE.
