Shipping a Small Deno Service Without a Build Step or a Security Blanket
Deno runs TypeScript without a build step and sandboxes every process behind explicit permission flags. Here's how that combination works for a real small service — and where it pushes back.
Choosing Deno Permission Flags for Secure Script Execution
A decision guide for granting Deno runtime permissions with granular allow‑lists, comparing them to --allow-all, and validating the chosen setup.
Deno Permissions: How Explicit Flags Secure Module Loading and Runtime I/O
Deno’s permission model forces explicit grants for I/O, tightening runtime security. Learn how to use flags like <code>--allow-read</code> to safely load modules and run scripts, with a concrete example and trade‑off analysis.
denojsGrant Deno Scripts Only the Access They Need — Then Lock It In
Deno scripts start with no filesystem, network, or environment access. How to scope permission flags precisely, encode them in deno.json, and where the sandbox leaks.
Managing Third-Party Risk with Deno's Explicit Permission Model
Stop trusting third-party packages blindly. Learn how Deno's explicit permission model uses granular flags to create a least-privilege sandbox for your JavaScript code.
Fine‑Grained Permissions in Deno: Grant, Revoke, and Secure Your Runtime
Learn how Deno’s permission system lets you grant only the access your script needs, revoke privileges at runtime, and avoid common pitfalls. A step‑by‑step example shows how to tighten security after startup.
