scaffold

Invoke the scaffold skill and provide the app type (HTTP or CDN), language, and project name. The skill reads blueprint reference files, creates the directory structure, writes working code, and prints build, test, and deploy commands.

HTTP apps support TypeScript, JavaScript, and Rust. CDN apps, which run as Proxy-WASM filters inside the CDN proxy layer, support AssemblyScript and Rust. The skill always asks for the language rather than assuming a default.

HTTP apps are standalone serverless functions that receive a request and return a response, like a normal endpoint. CDN apps run as filters inside the Gcore CDN proxy layer, intercepting and modifying traffic in flight before it reaches the origin or client.

Available blueprints include KV store, A/B testing, outbound fetch, headers and environment variables, and geo-redirect for HTTP apps, plus JWT auth and geo-blocking for CDN Rust apps. If no blueprint matches, the base skeleton is generated and custom logic is added afterward.

FastEdge captures stdout only, so eprintln!, eprint!, and stderr-based loggers are silently dropped. The scaffold skill greps generated Rust code for these patterns and rewrites stderr macros to println! before finishing.

Yes, CDN apps support AssemblyScript with TypeScript-like syntax. The skill first loads the AssemblyScript constraints reference covering limitations like no try/catch and no closures over mutable state, then generates the project with npm build scripts.
