Build the Back-End For Your Own Instagram-style App with Cloudinary

Github Repo

Managing media files (processing, storage and manipulation) is one of the biggest challenges we encounter as practical developers. These challenges include:

A great service called Cloudinary can help us overcome many of these challenges. Together with Cloudinary, let's work on solutions to these challenges and hopefully have a simpler mental model towards media management.

The process to building this solution is a hands on example which will get our hands dirty but a practical approach. Instagram and Flickr are known for heavy image processing so we can take inspiration from these apps and build something similar.

Build A Miniflix in 10 Minutes

Developers are constantly faced with challenges of building complex products every single day. And there are constraints on the time needed to build out the features of these products.

Engineering and Product managers want to beat deadlines for projects daily. CEOs want to roll out new products as fast as possible. Entrepreneurs need their MVPs like yesterday. With this in mind, what should developers do?

Your Web Image is Unnecessarily Bloated

By Christian Nwamba
Your Web Image is Unnecessarily Bloated

As a developer, it seems inefficient to serve a 2000kb JPEG image when we could compress images to optimize the performance without degrading the visual quality.

We are not new to this kind of responsibility. But our productivity will end up being questioned if we do not deliver fast. In order to do so, the community has devised several patterns to help improve productivity. Let's review few of these patterns based on their categories:

Viral Images: Securing Images and Video uploads to your systems

When was the last time you got paid $40,000 for a few days of work? That is what happened last year to Russian independent security researcher Andrey Leonov, who discovered that if you upload a specially constructed image file to Facebook, you can make Facebook's internal servers, nested deep within their firewalls, run arbitrary commands to expose sensitive internal files in a way that could easily lead to a data breach.

ChatBot for Image Manipulation

By Prosper Otemuyiwa
ChatBot for Image Manipulation

Bots - which have been around for a long time and perform different functions - are gradually replacing traditional applications. Consider Internet bots, also known as web robots, as software applications that run automated tasks over the internet, such as crawling websites and indexing search engines. Slack, the popular business messaging service, also popularized the use of bots for almost anything, from tracking stand-ups and sending reminders, to activating continuous integration and different types of activities.

Find images & videos with a robust new search engine

Great content is hard to come by. You can invest a lot of time and effort in building a great media library, but if content managers and editors can't quickly find what they need at the right time, it's almost useless (and frustrating). Good search capabilities allow you to provide them with a better experience: present relevant content or a well-organized catalog by a variety of criteria such as tags, folders, size, resolution, aspect ratio, faces, colors and many more.

Should You Transform Images On Upload or On Demand?

By Christian Nwamba
Should You Transform Images On Upload or On Demand?

As a developer, you hope and anticipate that your website or mobile application will be accessed by different users on various devices. To improve the user-experience, irrespective of the viewing device, you need to make sure that each image adapts to different graphic layouts, device resolutions and other viewing requirements. For example, for an E-Commerce site, one image will be displayed on different pages — home page, product page, shopping cart and more — and will be viewed on a desktop, cellphone or a tablet. This means that you need to create numerous versions of every image and for a website with hundreds of images, manual manipulation is not scalable.

Don’t let your digital assets become a liability!

Everyone is a content producer today - from the largest publishing house and entertainment studio, down to the smallest ecommerce store, corporate website or personal blog.

Let users upload images from Facebook, Dropbox and more

As developers of web apps, you often need to let users upload files to your app - mainly images and videos. You want the upload interface you provide to offer an intuitive user experience, including the ability to drag & drop multiple media files, preview thumbnails of selected images and videos, view upload progress indication and more. Since we now all live in the cloud era, chances are that many of your users also store media files in the cloud rather than only locally on hard drives and mobile devices, so the option to pick files from social networks like Facebook, cloud storage services such as Dropbox, photo services like Google Photos and more is a big advantage.

Auto padding images with content-aware color padding

How you present the content of your website can be just as important as the content itself. The images you display need to conform to the graphic design of your site, and every image needs to fit within a predefined size. Although that may be simple enough to achieve when you are dealing with your own images, the task can be more challenging when displaying images uploaded by your users.

Getting a Better React-ion with Progressive Web Apps

This is part 2 of a 3 part series

React has become more popular, as well as more mature, over the last four years since its release by Facebook. It has become one of the go-to technologies for people looking to componentize the front-end of any web application. It also helps that an entire mobile stack is built around React in the form of ReactNative. The components are wonderful, however there can be a burdensome learning curve. But, in the end, there’s the payoff of highly reusable code and a better user experience.

Build an Image Library with React & Cloudinary

This article was originally posted on Scotch.io

React is a good tool when it comes to building flexible and reusable UI components. However, it's "one of those libraries" that cannot handle all the tasks involved in building a full fleshed UI project. Other supporting tools - such as a recently announced React SDK from Cloudinary - are available to provide solutions that the React core cannot.

Getting Started with Vue JS: The Progressive JavaScript Framework

The most challenging aspect of building a product with a front-end framework is focusing on the complexity of the tool rather than the complexity of the actual problem being solved. It’s perhaps more frustrating when the tool is complex but the problem is a simple one (e.g. complex webpack config for a todo app). The term progressive, is used by Vue.js to describe how this challenge can be mitigated. Building a basic demo or small app? Vue.js is simple enough to handle that. How about a complex enterprise app? Vue.js is capable of produce cutting-edge solutions, as well.

Easy upload and display images in your app with iOS SDK

Embedding and managing images and other media content in a mobile application is always challenging. The processes of downloading a media file from the web, storing it on the device, and then displaying it to the user are surprisingly and often frustratingly complex from a coding perspective. In addition, you probably want to add code that enables reusing images rather than downloading it every time, but you have to be smart about it to avoid clogging the precious storage space on your customer's device. Furthermore, your design probably requires that images be displayed in different sizes and DPRs in different devices, but creating and maintaining multiple versions of every image manually is virtually impossible.
