Space Radar Electron

SpaceRadar allows interactive visualization of disk space and memory. It currently supports Sunburst, Treemap, and Flamegraph charts.

Downloads

Download Mac and Windows at the releases page

Features

space visualizations using sunburst and treemap charts
previews visualization as disk is being scanned
fast (completes disk scanner faster than du)
cross platform (at least on Mac OS X and Windows)
allow drilldown of directories
breadcrumbs and navigation
opens files and directories
analyze disk contents from a remote server (see section Reading from a file)

Screenshots

Reading from a file

To create a file to be read from use du -ak, for example:

du -ak /var/log /usr | gzip -c > /tmp/sizes.txt.gz
du -ak /opt /home /tmp > /tmp/sizes.txt

Compressed files can be read directly. To detect them, the file name has to end with .gz.

Future Enhancements

more target for scanning
color by file types
filter hidden files
moar!!
let me know what you think

Futher Explorations

More efficient memory usage
More efficient scanning process
3D visualization

History

This project started as quick prototype for me to test drive electron (& some es6 syntax), d3.js and for me to explore the question of "what's taking up my disk space". Turns out writing a disk visualization app isn't that simple as I dwell into figuring out how to make disk scanning not block the ui thread, ipc calls go faster, smoother rendering, lesser memory usage, more sensible interactions...

Whats New

Import from DU file
Upgrade electron
Flamegraphs (BETA)
Directory Listview
Update libs - Electron, D3

Treemap view
Memory monitoring
Mac App look using Photon
Context Menus for locating + opening + deleting files / directories
Navigation controls (back/fwd/up)
Switched disk scanning jobs to invisible renderer process

Version 3

App icon finally! Thanks Jill for the help with this :)
Many Bug fixes
Disk scanning is moved to a webview process
Investigated various RPC methods. Now uses LocalStorage + FileSystem IPC message passing
Reduce memory usage (and Electron crashes) by not caching key paths
Tested on > 100GB & 2M files
Improvements to user interactivity esp on hover states
To prevent renderer process from hitting heap mem limit (1.5GB), all previous data is null, with dom elements removed to reduce memory pressure
Allow target selection for disk usage scanning
Locate path in Finder
Env Debug Flags

Version 2

Major speed up scanning directories. About 10x from version 1, and almost as fast or faster than du.
Runs disk scanning as a separate headless renderer process
Json is passed back via IPC
Remove Async npm dependency

Issues

Please raise on github issue tracker or contact @blurspline on twitter

Development

Run

npm run debug

npm run app

Check that dependencies are installed, otherwise run (this may take awhile for electron binaries)

npm run install

Thanks

Jill for designing the app logo
Jianwei for his comments on the app
Chee Aun for helping alpha test the app
WM for his talk on Electron that got me started
