As highlighted by the development team at RNF Technologies, here are inevitable mistakes that many make that cause applications to run slowly:
- Too many scripts and libraries from third parties
As our application gets more significant, there is a good chance it will have too many Node dependencies, plugins, or even scripts, which will harm how quickly it runs. Eliminating pointless dependencies will be beneficial.
- Lack of CDN
Using an Information Delivery Network is an excellent approach to improve your app’s performance if it contains a lot of web content (CDN). It distributes your static material from a nearby server with a quick download rate.
- Excessive HTTP requests
HTML is complicated and essential for DOM object querying and modification. The DOM speed of the app might increase twofold when the HTML is decreased in half. Although it can be difficult, it is feasible to remove tags like “div” and “span.”
- Utilize HTTP/2
- Utilize pointer references
You can also minimize DOM traversal trips by keeping pointer references for in-browser objects during instantiation. Maintaining a reference to the DOM or jQuery objects required to build your website can speed things up if you don’t anticipate your DOM changing. Alternately, you can create a local variable regarding the object if you need to iterate inside a function but haven’t stored a reference.
- Minimizing and simplifying the coding
- What justifies using this framework?
- Does the overhead make sense?
- Is there a more straightforward method to complete this?
- Batch your DOM modifications
Batch up your DOM updates each time to avoid rendering the screen repeatedly. Try to update your styles at once rather than adjusting each style separately if you’re changing your style.
- Make DOM buffers
If your DIVs are scrollable, you can utilize a buffer to remove DOM elements that aren’t currently visible from the viewport. By using this method, you may reduce memory utilization and DOM traversal.
