Bare: Holepunch's minimalist JavaScript runtime for serverless P2P applications

Bare: Holepunch's minimalist JavaScript runtime for serverless P2P applications

Original: Kill the Server: Why Holepunch Threw Away Node.js and Built 'Bare'

Short summary

Holepunch built Bare, a minimalist JavaScript runtime that strips away Node.js's server-centric standard library to enable true peer-to-peer applications. Bare abstracts the JS engine behind libjs, allowing swaps between V8, QuickJS, and JerryScript for different deployment targets. It ships with only module systems, native addons, and lightweight threads, leaving networking to userland modules like HyperDHT.

  • •Bare is a minimalist JS runtime that removes Node's server-centric APIs for P2P use
  • •libjs abstraction allows swapping V8 for QuickJS or JerryScript on constrained devices
  • •Only three core primitives: modules, native addons, lightweight threads—everything else is userland
