A platform that generates a year in review video for each GitHub user. Built with Next.JS, Remotion and AWS Lambda.
Make your own
Want to make your own year in review for your users?
- Developers: Feel free to fork use this repository as a template! Note the legal disclaimers at the bottom of this README.
- Non-developers: Write to firstname.lastname@example.org for a free consultation in Fall 2023!
npm ito install dependencies.
Set up your AWS account according to the Remotion Lambda Setup guide. We use multiple accounts for load-balancing:
- You can use
AWS_SECRET_2to load-balance between two accounts, or paste the same credentials as before to use the same account.
src/set-env-for-key.ts, we rotate the environment variables.
Deploy the functions into your AWS account(s):
npx ts-node deploy.ts
Note that some AWS regions are disabled by default. If you get an error, enable them or limit yourself to only default ones.
For caching the videos and GitHub API responses, set up a MongoDB (We use a free MongoDB Atlas Cloud instance) to save the videos. Set the connection string as
For fetching data from GitHub, create a personal access token in your user settings (no need to grant any scopes, the GraphQL API needs to be authenticated to get public information) and set it as
GITHUB_TOKEN_1. Adding more tokens
GITHUB_TOKEN_2etc. will rotate the personal access tokens.
DISCORD_TOKENvalues to send monitoring logs to Discord.
You now have all environment variables.
Run the web app:
npm run dev
Edit the template in the Remotion preview:
npm run preview
To deploy, connect your repository to Vercel.
Don't forget to also set the environment variables there too.
To allow thousands of people to render their video at the same time, we applied multiple strategies for scaling:
- Caching the video whenever possible. Before each render, a MongoDB database lock is created to avoid multiple renders for the same GitHub user to be accidentally created.
- Renders are distributed across an array of AWS regions and accounts to avoid hitting the concurrency limit.
We thank GitHub for their support in realization and promotion of this project.
