## Transcript

in this video, I'll show you I built out a NexJS uh Tik Tok uh post downloader application in the browser which actually allow you to actually download actually allow you to actually download images, videos, any sort of profile,
post. So this is actually the interface of the application. It directly runs in number of time. We are communicating with the official Tik Tok API in the background. Let me show you the demo here. So if you take any example here,
if you copy link address of any Tik Tok post, paste it inside this search bar and once you click this button right here. So what this application will do in the background, it will make the request to the Tik Tok API and then it
will fetch the download link and also display the video of the Tik Tok as you can see. So side by side, you will also be able to play the video as well.
can download this video inside your machine or you can even extract the audio as well. So for doing this once you click the download button you click the download button automatically you will see now this
you can actually save this as MP4 file. So it is prompting me. So you can simply save this. So now it is successfully saved inside saved inside the computer. So you will see that. So
So this is actually the thing video downloaded. So you can even right click downloaded. So you can even right click as click the download here as well. So in this easy way you can basically paste any link. Let's suppose I copy this link
address. So you can do this unlimited number of times. It's built entirely in nextJS. Again you click the download button again. It will fetch the post and actually display the video side by side. So if you are interested in purchasing
this full source code, I have given the link in the description. actually a full nextjs project. So you can see again it fetch the actual
video and display the you can play the video as well. full directory structure of the demo right here. Once you actually purchase
code automatically from Google drive. And this is actually I've divided this. This is we are making the API calls in these files here in Typescript files. So
we are actually making official calls to Tik Tok API. If I show you package.json file, this is overall. We are using Cheerio library in order to make the request to the API XOS as well. We are also using ffmpg in the background as
well. And we are using latest version of next react. As you can see it's a full project. If you are interested, I've given the link in the description. You can directly purchase it, the source code. And once you get the source code,
you will get an idea on how I developed this application from scratch. And you will also be able to add additional features on top of this source code as well. So you can just see the directory structure right here.
And it's very easy to run this. We are running it locally as well. So you can running it locally as well. So you can see we are actually making the API call right here in the so we are running this locally this project you can even run it
locally deploy this application as well once you get the source code it's very once you get the source code it's very simple so it's a simple NexJS project so here you simply paste uh whatever URL that you want to it can be a image it
can be a video it can be anything you simply need the link and You basically plug the link here and just click download and instantly the API will
work. [snorts] We inside this is actually a single page nextJS application. So if you are interested in this the link is given in the description. You can actually
purchase the full source code and it actually allows you to actually fetch the video links, [snorts] image link, profile links, any link. You basically profile links, any link. You basically paste the URL of the Tik Tok post and
paste the URL of the Tik Tok post and then click this button and instantly it will you can see the video is fetched. So now you can play the video here and or you can extract audio or click the download button. All the things you
can do. So we are running it. I'm just showing you a short little demo of this application. So if you are interested you can even run this inside your own machine or you can even build out application as well. So it's really
application as well. So it's really simple. So you can just see here. is divided into its appropriate TypeScript file here. So you can just
see it's a fullyfledged project. I developed this from scratch. Each and every line of code I written it from scratch. So if you face any sort of problem I will be happy for to help you if you face any sort of issues in
running this code. So I have given the link in the description of the video. So you can directly purchase it and it's actually using the official Tik Tok API for fetching the download links. So you
can do this unlimited number of times. So there is no restriction. So no need to replace any sort of API key. So this is we are executing it without any API
So I'm just in the background we are communicating with the Tik Tok API to fetch these download links to actually
embed the video side by side. So this is the overall project. If you are interested I've given the link in the description.
