JavaScript Sandboxing Research Compares Node.js Options
|
6.1
On 22 March 2026, a research note analyzes current JavaScript sandboxing options for running untrusted code, comparing Node.js core approaches (worker_threads, node:vm, Permission Model), npm packages (isolated-vm, vm2) and alternative engines (quickjs-emscripten, QuickJS-NG, ShadowRealm, Deno Workers). Claude Code expanded on Aaron Harper's worker_threads discussion, highlighting security and performance trade-offs for practitioners.
Scoring Rationale
Practical, timely comparative analysis across Node.js sandboxing options, but limited novelty and single-source depth restricts broader impact.
