Function composeAround

composeAround(...hooks: AroundHook[]): AroundHook

Compose multiple around hooks into one using the "onion" model.

Each hook wraps the next, forming a chain where:

The highest priority hook wraps closest to next (innermost)
The lowest priority hook wraps closest to the caller (outermost)

Execution order (example with 3 hooks):

hook0 (outermost)
  → hook1
    → hook2 (innermost)
      → next()
      ← hook2 returns
    ← hook1 returns
  ← hook0 returns

Parameters

...hooks: AroundHook[]
AroundHooks to compose (applied in priority order)

Returns AroundHook

Single composed AroundHook

Example

const timing = (ctx, next) => {
  const start = Date.now();
  return next().finally(() => {
    console.log(`Duration: ${Date.now() - start}ms`);
  });
};

const auth = (ctx, next) => {
  ctx.request.headers.Authorization = `Bearer ${getToken()}`;
  return next();
};

const composed = composeAround(timing, auth);
