Simple Website/API for downloading instagram videos made with Next.js 13 app directory

A website that lets you download Instagram videos easily and quickly. You can paste the URL of any public Instagram post and get the video file in MP4 format. there is also an API that you can use to integrate this functionality into your own applications. The API is simple, and it returns JSON responses with the video URL and other metadata.

PS: Instagram stories aren't supported.

You can preview and try the website live in vercel here : riad-insta.vercel.app

The frontend includes the following:

• Dark/Light themes supported.
• Responsive UI on mobile.
• Easy and User friendly UI (Interactions feedback and error messages).

1.Cloning the repository

git clone https://github.com/riad-azz/instagram-video-downloader.git

2.Installing dependencies

cd instagram-video-downloader

npm install

3.Starting the server

# Development
npm run dev

# Build
npm run build

# Start
npm run start

4.Testing

I am using jest for testing which is pretty simple and easy to use. You can find all the test files in src/__tests__.

# Run all tests
npm run test

Run a single test

# Run a single test
npx jest -t "<test-name>"

# Example
npx jest -t "success-fetchPostJson"

Incorporating this feature may be considered advanced and is not recommended if you don't know what you are doing. I will not go into details on how to obtain the Session Cookie, but to put it simply you have to login to your Instagram account and open the developer tools of your browser and go to the networking tab and you should be able to find your Session Cookie in the request headers.

I do not recommend using this if you host your application on a serverless platform because your Instagram session is likely to expire due to the account being accessed from different regions.

To enable this simply follow these steps:

1. Set enableUserApi to true in src/configs/instagram.ts .
2. Create .env.local file in the root directory of the project.
3. Get your Session Cookie from Instagram (I recommend using a dummy account for this).
4. Copy the Session Cookie and paste it in the .env.local as AUTH_COOKIE file that you created.

If you are confused just check .env.example and copy whats there then replace with your Session cookie.

This is how your .env.local should look like:

AUTH_COOKIE="YOUR-IG-SESSION-COOKIE"

Note : If your cookie contains \054 which most likely it will, this is known as an octal escape sequence and you will have to escape all of them by adding backslash \\054. If you don't do this you will get an error and the app won't run.

Here is an example (this is not a real cookie it's just for demonstration) :

AUTH_COOKIE='...etc; rur="CLN\05459230432636\0541719114429:01f7f46f618c340f4457ebb";'

After adding the backslash to all the octal escape sequence it should look like this :

AUTH_COOKIE='..etc; rur="CLN\\05459230432636\\0541719114429:01f7f46f618c340f4457ebb";'

In order to reduce the load on the API and ensure optimal performance, I have implemented rate limiting using Upstash. This integration allows me to restrict the number of requests made to the API within a specified time frame, preventing excessive traffic and potential service disruptions.

To set up Upstash create .env.local file and insert your URL and Token:

USE_UPSTASH="true"
UPSTASH_URL="YOUR-UPSTASH-URL"
UPSTASH_TOKEN="YOUR-UPSTASH-TOKEN"

All ratelimit configs can be found in src/configs/upstash.ts.

If you would like to change the identifier (default is IP) you can change it in src/middleware.ts.

The API is pretty simple and straightforward.

Parameters :

• url : Instagram Post or Reel link (required).

curl -i "https://riad-insta.vercel.app/api?url=https://www.instagram.com/p/CGh4a0iASGS"
