Samvaad provides you with the latest news from all over the world in 7 different categories from different sources. You can get trending news from here. This was my first React Native project which I made from scratch. Learnt about how to pass props from parent to child components and how to call parent functions from child. The backend is made using Flask and python requests module calls NewsApi and then sends the data to the frontend. Since NewsApi has a limit of 100 requests per day, try catch mechanism can serve around 1500 requests per day.

Things to do:

• Caching mechanism to cache the news this will help the backend to serve even more requests.

Technologies used

• Frontend: React Native (Javascript)
• Backend: Flask

UV stands for universal downloader. We all love to listen to music, some play it using Spotify some use Youtube, but almost all the music streaming platforms are filled with annoying ads and most of the songs are not available for offline download. People want to share some videos and media with our friends and family but they prefer sharing the original video instead of a link, but this is not possible for most of the platforms.

UV Downloader solves this problem by enabling users to download HD videos and High quality audios at high speeds, users can download media from websites like Facebook, Instagram, Youtube, Reddit and many more. UV Downloader also provides a file system for users to navigate through their files and downloads. Users can also browse the web within the app and find the media they want to download.

• The first version of this app was made using Javascript and Context API.
• The second version of this app was made using Javascript and Redux Core.
• The latest version of this app has Typescript enabled and uses Redux Toolkit.

First Version The most difficult part of this project was finding the proper library with compatible version, initially while building this (I was using Javascript back then ) I faced a lot of bugs & errors, almost to a point where I almost gave up. React Native Fetch Blob may help you to download files via url but many times it fails and sometimes even download does not even start, so it was not an reliable option. Then I switched to React Native FS, and while installing this library I again got a lot of build fails, but eventually when this was ready to use, I found out that it’s the most reliable library for downloading files from the internet, it also has many options which enables the developer to build feature rich applications moreover its free and open source. Now the problem was how do I show that the download has started and its progress (react-native-fs gives you the download progress asynchronously), now the problem is I have to store and update this data from somewhere. So as at that time I was familiar with context api (which I will regret later). Now due to the frequent updation of the download status, the downloading file component was flickering, and when more downloads are added it started to flicker even more. So now I knew that using context api is not a good idea. This was the first version which was made using Javascript and Context API.< Second Version Then I built a new branch and switched to redux, the code became more simpler and there was no flickering even though 10 files were getting downloaded at the same time. This was the second version of the application where I was using Javascript and Redux Core.< Latest Version I could have stopped here but I wanted to solve one more problem, what youtube does is, it has audio and video (only the high quality ones) as separate files, till now I was showing only the lower quality video files (480p to 720p max) that have audio embedded in them, but now I had to change this, I decided to introduce another very important library to our application FFMPEG. What FFMPEG does is, it merges the video and audio into a single output file whose extension can chosen by the developer (I kept it to mp4 since it’s the most widely used video file format). Now the challenge was how to install FFMPEG because the documentation is not properly written, and I spent around 2 days just to install FFMPEG min version. Meanwhile I recently worked on Treklers passenger app which I made from scratch in Typescript, so I knew how beneficial Typescript is for this project. Then I rewrote the entire project in Typescript and installed Redux Toolkit and after all of this was done. I started working on Downloading the audio and video, merging them together and then deleting the source files. Typescript really helped here I faced no bugs while making this feature and thus the third and the latest version of the app is ready, which is written in Typescript and has Redux Toolkit for state management.

Things to do:

• Better UI/UX
• Add support to enable download from different websites
