Instafeed data code#

We need to store user profile data like the follower list, uploaded photos by users. Our system would need some object storage servers to store photos and some database servers to store metadata information.Дefining the database schema is the first phase of understanding the data flow between different components of the system. We need to support two scenarios at a high-level, one is to upload photos, and another is to view/search photos. It will help to keep your focus aligning with the requirements of the system. If you are not sure where to start in a system design, always start with the data storing system. While viewing photos, latency needs to be as low as possible. As the system would have more read-heavy operations, we will focus on building a system that can retrieve photos quickly. In this system, photos search and views would be more than uploading. The system should also be highly reliable, which means any uploaded photo or video by users should never be lost. If the home page generation takes too long, users will be dissatisfied, which is not acceptable.ДЄs we choose for the systemвЂ™s high availability, we should keep in mind that may hamper consistency across the system. Home page generation latency should be at most 200 msec. In the case of any web service, itвЂ™s a mandatory requirement.

We need to have requirements that will work as restrictions on the design of a system. But itвЂ™s not possible to achieve all these targets in one system. We need to analyze these requirements for the system.ДЄs a system designer, we might want to have a design that will be highly available, very high performant, top-notch consistency in the system, highly secured system, etc. Performance, availability, consistency, scalability, reliability, etc., are important quality requirements in system design. Another essential feature is that the system should display a userвЂ™s News Feed that consists of photos of all the people the user follows.ДЄs this is a practice for the system, we are not considering tags in photos, tag-based search, like and comment features, etc. Users may perform searches for images based on photo/video titles. You may say it is the main goal of the system.ДЇirstly, for Instagram, the users should be able to upload/download/view photos. This type of requirement what the system has to deliver. The system requirements are divided into two parts: In this part, we select the features of the system. The вЂNews FeedвЂ™ consists of top photos of all the people the user follows. In this service, a user can share photos and follow other users. As this is an exercise, we will design a simpler version of the main Instagram service. Result = this._makeTemplate(, ).call(this) ДЄny help with this issue would be GREATLY appreciated.Instagram is a photo-sharing service that enables its users to upload and share their photos and videos with other users, mostly their followers. $(image).addClass('animated fadeInUp pic-'+count++)

Instafeed data code#

A sample of the current working code with only 1 image displaying can be found here. What I'm trying to accomplish is to have 9 items display, then if I hit the 'next' button, it would replace the current 9 images and load the next 9 images and, if the 'previous' button is clicked it would go back and show the previous 9 images.Д¬urrently it only renders one image thumb that scrolls through 9 images then stops. I am currently using the instafeed.js ( ) script to pull in images from instagram and display them on my site. I have been able to find many answers to my questions and hope to do the same with this one. This is my first post on StackOverflow and might I say, what a great and helpful resource this is.
