- 2. Angular is a great JavaScript framework of modern-day for building interactive components as well as elements. It is widely used for building SPAs and dynamic programming structure. The front-end framework is based on TypeScript with additional features like interfaces, classes, and static typing that encourages component-based development and make sure that components are decoupled as well as conveniently reusable. Images play a significant role in page-load times, and that’s the reason if you want to improve the performance of your web application, lazy-load images come handy.
- 3. So, let’s start with what is Lazy Loading?
- 4. Lazy loading, also known as on-demand loading, is an optimization technique that delays the loading or elements or components until they are brought into the viewport. When you log in to/admin, you will come across a JavaScript code ‘chunk’ specially designed for the Admin dashboard. Likewise, when you load /shop, you will get a similar “chunk,” specially written for the Shop! The code is lazy loaded and injected into the browser for the specific use of the Shop module. main.chunk.js // loaded everywhere shop.chunk.js // lazy module admin.chunk.js // lazy module In a layman’s term, while scrolling any eCommerce website, the bottom images of a page will only be displayed when the user scrolls there.
- 5. Lazy loading in Angular, why it needs your special attention and importance?
- 6. It is one of the proven ways to improve the performance of your website. Reduce Page Load Time: Load only requested elements and helps to reduce the amount of data to be loaded. Conserving Bandwidth: Helps to save bandwidth from the viewers as well as a web browser. Deliver only required content and refrain from sending unnecessary content. Save System Resources: Render code only needed. Save memory resources.
- 7. How to Implement Lazy Loading in Angular? ngx-loadable is a lightweight package for implementing Angular based lazy loading components. It contains a simple API to support loading indicators.
- 9. Stap 1. Install ngx-loadable in npm/yarn and add LoadableModule in your AppModule. Stap 2. To add a module with a bootstrapped, follow the listed below command using Angular CLI. Make sure that module, as well as component names are same.Adding components in the bootstrap is significant as well. Step 3.
- 10. Step 4. Hovering on the mouse button, you will find that LoginModal Module is pre-loaded. When clicking shows it is still downloading, then LoginModalComponent loads in the ngx- loadable element. Configure ngx-loadable using custom paths. Bypassing configuration to the LoadableModule.
- 11. Lazy-loading non-routable modules—ngx- loadable is a convenient approach to managing lazy loading. To boost the performance of your application, I strongly recommend it to optimize it step-by- step, instead of doing it all together in one big step. Once you follow the above steps and if you see a chunk, then you have configured it in the right way.
