Type Alias Middleware

Middleware: (
context: RequestContext,
next: () => Promise<void>,
) => Promise<void>

A middleware function in the request pipeline.

Call next() to pass control to the next middleware or the endpoint handler. If next() is not called, the pipeline short-circuits.

- (context: RequestContext, next: () => Promise<void>): Promise<void>
- Parameters
  - context: RequestContext
  - next: () => Promise<void>
  Returns Promise<void>

Example

const logger: Middleware = async (ctx, next) => {
    console.log(ctx.method, ctx.url.pathname);
    await next();
};
