CURRENT READ
Minimalist core, delegated everything — auth, parsing, logging live elsewhere, while tight inline checks betray a framework that trusts middleware more than itself.
HOW THIS UNDERSTANDING FORMED
FIRST IMPRESSION
A minimalist framework that ships zero features — every capability is delegated, so the app says what it is by what it imports.
TENSION OPENED
Bodies and queries delegated to parsers, yet request objects prototype-augmented — the route layer decides, the object smuggles the rest.
TENSION OPENED
Both embrace options, but eager at set-time versus lazy at use — the compiler's in the file, not the call.
TENSION OPENED
Express prefixes cookies at runtime; Nebula weaves metadata at compile time — both encode semantics, but one decides at the edge, the other at the build.
TENSION RESOLVED
Normalization is a reflex here, but domain-specific — dates converge to canonical instances, configs compile into executable functions.
TENSION RESOLVED
Options handled two ways — date-fns demands context, express compiles at set-time — yet both ignore the other's contract.
TENSION RESOLVED
Cookie signing splits into two systems — library prefixes here, HMAC JWTs with jti there — same trust, no shared doctrine.
TENSION RESOLVED
Errors are typed at the core but untyped at the edge — the model diverges where the discipline stops.
TENSION RESOLVED
Pipeline stages own the parsing; Express leaves it to plugins—this repo chooses contract before convention.
TENSION RESOLVED
Shared libraries for cookie signing, yet validation throws bare built-in errors — inconsistencies in failure signaling persist despite cross-cutting care.
TENSION RESOLVED
Lazy engine loading at render-time, eager settings compile at set-time — the framework splits its own brain on when to pay for behavior.
TENSION RESOLVED
Silent at the boundary, loud at validation — one boundary fix, two philosophies.
TENSION RESOLVED
HMAC JWTs for sessions, cookie-signature for cookies — two secure mechanisms, but the repo's stakes in identity don't align even within its own trust boundary.
