The lazy loading is not so lazy in 2018
Thursday April 12th, 2018
Images are everywhere. Sometimes, images are the core focus on the content. However, it takes a lot of time and memory to load all images. Normally when a user opens a webpage, the entire contents are downloaded. While this allows the browser to cache the web page, there’s no guarantee that the user will actually view all of the downloaded content. The user might only see the first image and close the page.
In order to avoid downloading whole contents on the page, the lazy loading technology, also known as dynamic function loading, creates placeholder content which is only replaced with actual content when the user needs it.
According to various experts, the lazy loading technology might rule in 2018.
In short, it allows a developer to specify which exact components of the software should be loaded into physical storage when a program is launched.
The lazy loading sounds like it is LAZY that it won’t load content properly. But in fact, the concept itself is widely used in real life. For example, when you cook something, you have to think about what to make first. Then choose and prepare ingredients. After you finish preparing them, you cook in the order. You “Lazy load” all the items and process.
The main advantages for the users include
1.Lazy loading strikes a balance between optimizing content delivery and streamlining the end user’s experience.
2.Users connect to content faster, since only a portion of the website needs to be downloaded when a user first opens it.
3.Businesses see higher customer retention as the content is continuously fed to the user, reducing the chances the user will leave the website.
4.Businesses see lower resource costs since the content is only delivered when the user needs it, rather than all at once.
The main disadvantage of lazy loading is that the code becomes more complicated – and users might experience a slight decrease in performance.
In the post, “App modularization and module lazy loading at Instagram and beyond” by Instagram engineering, Lazy loading helped Instagram to bring a combination of benefits like improved cold start time and overall runtime, decreased disk footprint, and better developer velocity if module hot-swapping is implemented. They also show how they approach lazy loading at Instagram and show how people can implement it in an app with their new open-sourced framework. INSTANT, Jmobile app which allows people to download content from Instagram, will also get affected by lazy loading technology.
Incorporation lazy loading into your mobile apps will significantly enhance the user experience of your mobile app. Most app developer will use this tactic in 2018.
