Bare modules
Catalog of `bare-*` runtime modules that supply Bare's standard-library functionality (process, fs, net, crypto, streams, …), grouped by area.
Bare modules
Pear's native runtime is Bare—a small, modular JavaScript runtime for desktop and mobile. The Bare global API is minimal and not intended as a standard library; standard runtime functionality is provided via installable modules prefixed with bare-. The modules below are grouped by area; within each group they're ordered roughly from foundational to specialized.
To run a script on Bare directly, see the bare CLI. To embed a Bare core inside a native app, see Bare Kit and One core, many platforms.
If you author native addons for Bare, the Bare native-addon prebuild actions build and collect prebuilt binaries across platforms in CI.
