GitHub Star History and Stats - based on JavaScript only, no server side!
Try it now: https://seladb.github.io/StarTrack-js/
Main features
- View a GitHub repo star history
- Show stargazer stats such as average number of stars per day, max stars in one day, etc.
- Supports showing multiple repos at the same time (very useful for comparison)
- Display a stargazer forecast based on the existing data
- Provide GitHub authentication (via access token) to overcome GitHub API rate limiter which limits the number of API calls without authentication. The authentication details are stored locally and not sent to any server
- By default they're stored in the browser's session storage
- The user can choose to store them in the browser's local storage for longer persistence
- Preloading repos by URL, for example: https://seladb.github.io/StarTrack-js/#/preload?r=seladb,pickledb-rs will preload
seladb/pickledb-rsupon loading the page
What's new in version 2.4?
- Added an option to display a forecast based on the existing stargazer data. The forecast is calculated using Linear Least Squares regression
- Change between username and repo name text boxes using the
/key (thanks @zaldih !)
What's new in version 2.3?
- Parallel load of stargazer data which significantly improves the overall loading time (thanks @gsaraf !)
- Display chart data in log scale (thanks @passcod !)
What's new in version 2.2?
- Added support for smaller screen sizes (mobile devices)
- Small improvements in overall layout
What's new in version 2.1?
- Added a checkbox to sync the stats with the current chart view displayed. This is useful for viewing stats on specific dates
- You can now paste a GitHub link instead of typing the username and repo name, and they will be parsed automatically
- Added a link to the GitHub repo in the badge displaying the repo details
- Preloading screen: fix decreasing transition in progress bar when loading the next repo
- All React components were replaced from class to function components and are using React Hooks
What's new in version 2.0?
- A complete rewrite using React and modern frontend technologies
- Significant UI improvements (basically everything looks much better now :-) )
- The chart component has been replaced and it's now easier to navigate, zoom in/out, etc.
- Added an option to remove repos (in version 1.0 you could only add but not remove)
- Added an option to stop loading data
- Each repo has a dedicated color throughout the page (chart series, stats, close button)
- Dedicated preloading screen
- Shows a progress bar for each repo separately
- Shows errors for repos which were not loaded successfully
- GitHub authentication improvements
- When logged in, a new tooltip shows where the access token is stored (browser's session storage or local storage)
- User + password authentication was removed as it's no longer supported by GitHub
Technical details
This project is built on React and deployed on GitHub Pages. It doesn't have a backend so all of the data is stored locally on the browser and nothing is passed to any server (other than GitHub API to fetch the stargazer data).
It uses the following npm packages:
- React Bootstrap for the UI elements
- ApexCharts for displaying charts
- Axios for fetching data from GitHub API
- React Router for having a separate view for preloading stargazer data
- Font Awesome for cool icons
- react-github-btn for displaying GitHub buttons
- React Google Analytics Module
- parse-github-url to find GitHub URLs that are being pasted to the repo details text boxes
- react-responsive for adjusting the UI according to the screen size (desktop vs. mobile)
- least-squares for calculating the forecast
Dev packages:
- ESLint, Prettier and their plugins for code linting and formatting
- husky, lint-staged and pretty-quick for pre-commit hooks
- gh-pages for GitHub Pages deployment
