Hey everyone! I recently worked on a web project where each time a user applied a filter, a new request was made to the backend to pull data from the database. This got me thinking—wouldn't it be more efficient to load the data once and then apply filters client-side using JavaScript instead of repeatedly hitting the database?
I'm curious about the pros and cons of using data structures and algorithms on the front end versus relying on backend processing (using C# in my case). What are the best practices for deciding where to implement this logic? In which scenarios is front-end filtering actually beneficial, and when should we just put that load on the server? I'd really appreciate any examples or insights you all might have!

If loading everything at once is needed, it might not be the best route. Imagine trying to store too much in memory and crashing the browser! If you think you’re going to be dealing with a lot of data, better to keep the logic server-side rather than give users a sluggish experience on the frontend.
You also need to be cautious about multiple tabs. If every tab tries to fetch and hold onto too much data, it just complicates things for the user.
Remember, the goal is to enhance user experience while managing resources efficiently. Assess the size of your data, how often it changes, and what devices your users might be on. Sometimes a smart caching solution can make all the difference, giving users a quick experience without overloading either the server or the client.
The main thing to think about here is the trade-off between querying speed and bandwidth. Pulling too much data can slow things to a crawl on the user’s end. Push for optimized database queries instead—using proper indexing can make a significant difference in reducing server load time while keeping your frontend snappy.
You really have to weigh the cost of database access against the cost of loading large datasets. Reusing client-side data can reduce backend load but can also lead to stale data if it's been open for a long time. Ideally, you'd want a caching layer on the backend to balance freshness with performance.
Applying filters client-side can be great for small datasets, but if you're working with something massive—like a million records—you'd end up eating up browser memory and processing time since you’d have to loop through everything every time. This could really slow down performance, especially on older devices. If you've just got a few hundred records, go ahead and filter them client-side, but keep in mind that some users might be on older phones with limited resources.
To put it simply: consider how much data you need to handle. If you're rendering tons of data, your browser might struggle and crash. Better to load data as needed!
I’d also point out that frequently changing data means you might want to keep querying. If user data changes often, loading all data once can lead to outdated info. Filtering client-side is quick for smaller datasets, but could backfire if the data is stale.
Exactly! There's a limit to how much data your users can handle at once. Do a bit of data analysis and make sure the user experience doesn’t suffer.
