How do you optimize web applications for mobile devices and browsers?

Optimizing web applications for mobile devices improves speed, efficiency, and user experience. Key strategies include reducing load times by minimizing HTTP requests and implementing lazy loading. Utilize modern protocols and compression techniques to streamline resources. Caching, CDNs, and service workers enhance performance and enable offline functionality. Improve rendering by optimizing CSS usage and minimizing DOM manipulations. Refine JavaScript through code splitting and efficient event handling. Focus on mobile-specific optimizations and Progressive Web App features. Continuously monitor performance metrics and balance frontend and backend optimizations. The end result: faster applications and improved user engagement.

Key indicators of web application performance include load time, responsiveness, throughput, and user satisfaction. Tools like Google PageSpeed Insights, Lighthouse, and WebPageTest can help measure and monitor these metrics. Benchmarking against competitors and industry standards provides context for performance evaluation. However, the most valuable insight comes from user feedback, as it provides a direct understanding of user satisfaction and areas for improvement. Therefore, incorporating user feedback is crucial to truly understand and optimize web application performance.

To optimize web applications for mobile devices and browsers, it is important to first define your performance goals. Key metrics such as load time, responsiveness, and user experience should be carefully assessed. Tools like Google Lighthouse can be used to measure these metrics and identify areas for improvement. In addition to using performance measurement tools, it is also important to monitor user behavior and gather feedback to understand how users are interacting with your web application. This can provide valuable insights into areas that may need optimization.

Optimizing Web Apps for Mobile: Strategies for Speed and Performance ???? Delivering a seamless experience on mobile devices is critical in today's landscape. Here's how you can ensure your web applications are optimized for mobile devices and browsers: 1. Responsive Design ??????? – Ensure your app dynamically adjusts to different screen sizes with responsive design frameworks like Bootstrap or media queries. 2. Lazy Loading & Compression ?? – Defer loading of images and non-critical assets until needed. Use compression (gzip, Brotli) to reduce data size. 3. Optimize for Touch & Speed ??? – Make buttons large enough for touchscreens, reduce animations, and minimize HTTP requests to improve load times. What's your tip? ??

Device specific performance baseline metrics are very essential to decide if the current performance of the application really needs to be improvised further.

For optimization of front-end application we can do it. - Optimization Frontend code using good approch when deal with storing data l, also deal with DOM. - Most time need backend collaboration, retrieve data as processed, not processing them in frontend. - Use memozation when you have same many requests or same processing. - Use offline first cache strategy for non recently updated endpoints. - Load js, css as batch, bundles. - Lazy loading assets .

To optimize front-end code and assets, it is important to follow best practices such as minifying code, compressing images, using Content Delivery Networks (CDNs), implementing caching, loading scripts asynchronously, optimizing CSS, and reducing the number of HTTP requests. These techniques can help improve website performance and user experience.

Must using responsive desing for web apps, but some website that have many functionality is better to be have different versions for different designs, to be more friendly with different dealing like tuch or mouse.

In order to make your web application suitable for different devices and browsers, it is important to implement responsive design techniques. This involves testing the application across various devices and browsers to ensure compatibility. Additionally, it is essential to ensure compatibility with cross-browser frameworks and to apply media queries to adjust layouts and styles based on screen size and orientation.

Ademas de la revisión de las reglas de escalamiento de los contenedores para poder garantizar que estos se despliegan en forma adecuada, tambien se debe tomar en cuenta la velocidad en lo que estos se despliegan. La cantidad de librerías y la tecnología utilizada debe ser valorada buscando rapidez en este aspecto.

Backend optimisation is too important for web applications because is effect whol user experience:- - Process data in data sources. - Use correct Data structure for storing data. - Must be database design serve performance of database using correct index, and some time renormalization db. - Using in memory cache for frequently data access. - Use memozation for avoid reprocessing same data. - Good infrastructure is important. - Using load balancing for web application. - Different servers for DB, Load Balance, Web app, Redis, worker.

In order to optimize the back-end code and architecture, it is essential to refactor the existing codebase, optimize database queries for efficiency, implement caching to reduce load times, use load balancing to evenly distribute traffic, design for scalability to accommodate future growth, monitor performance to identify bottlenecks, and utilize asynchronous processing for improved responsiveness. These steps will help improve the overall performance and reliability of the system.

DB queries need to be monitored for its elapsed time beyond a threshold. In the case of Mobile Apps, we need to monitor the volume of data that is fetched beyond a volume threshold using tools like OEM and custom scripts. If such a query is frequently fired and fetching almost same data over a specific time window, then we can think of placing features of Oracle Result Cache at DB side and if the compute is complex, the result should be pre-captured by way of MVs at DB layer with suitable change of query at the App.

To optimize your database and queries, it is important to follow best practices such as using indexing, optimizing query performance, normalizing tables, using stored procedures, performing regular maintenance, analyzing query performance, and implementing caching. These techniques can help improve the efficiency and speed of your database operations, leading to better overall performance.

In one of the performance analysis, the poor performance of the App was due to a poor design, in which an individual customer's spending was compared with average spending of people living in the zip code. The app was calculating this 'average' data every time though its result will not change atleast for 1 full day. if there was 1 million users use that feature in a day, then for no reason, that complex job of avg() at zip code would run which will consume resources for no gain. When this design was changed with pre-calculated zip level avg spending data,once in a day, there was a remarkable improvement in performance.
