Run a subprocess with administrative privileges, prompting the user with a graphical OS dialog if necessary. Useful for background subprocesse which run native Electron apps that need sudo.
Windows, uses elevate utility with nativeUser Account Control (UAC)prompt (noPowerShellrequired)OS X, uses bundled applet (inspired by Joran Dirk Greef)Linux, uses systempkexecor gksudo (system or bundled).
If you don't trust binaries bundled in npm package you can manually build tools and use them instead.
- Supports
spawnandexecsubprocess behavior - Supports applications packaged as
asararchive - Separate password prompt for each call (use
shorbatscript for single prompt) - No external dependencies, does not depend on OS versions
