Custom decorators

Вы можете добавить любой декоратор и поместить его в систему DI.

Пример с hooks:

import {  BusinessType,  container,  Content,  Context,  getMetadataArgsStorage,  HookTarget,} from "https://deno.land/x/alosaur/mod.ts";
type AuthorizeRoleType = string | undefined;
/** * Authorize decorator with role */export function CustomAuthorize(    scheme: AuthenticationScheme,    payload?: AuthPayload,): Function {    return function (object: any, context: { kind: "method" | "class"; name: string }) {        const controllerId = getOrSetControllerId(context as ClassMethodDecoratorContext);
        // add hook to global metadata        getMetadataArgsStorage().hooks.push({            type: context.kind === "method" ? BusinessType.Action : BusinessType.Controller,            object,            target: object.constructor,            method: context.name,            instance: SLContainer.create(AutorizeHook),            payload: { scheme, payload },            controllerId,        });    };}
export class AutorizeHook implements HookTarget<unknown, AuthorizeRoleType> {  onPreAction(context: Context<unknown>, role: AuthorizeRoleType) {    const queryParams = getQueryParams(context.request.url);
    if (queryParams == undefined || queryParams.get("role") !== role) {      context.response.result = Content({ error: { token: false } }, 403);      context.response.setImmediately();    }  }}
export class AutorizeHook implements HookTarget<unknown, AuthorizeRoleType> {  onPreAction(context: Context<unknown>, role: AuthorizeRoleType) {    const queryParams = getQueryParams(context.request.url);
    if (queryParams == undefined || queryParams.get("role") !== role) {      context.response.result = Content({ error: { token: false } }, 403);      context.response.setImmediately();    }  }}

Затем вы можете добавить где угодно. Например метод контроллера:

// ..controller
  // action  @CustomAuthorize("admin")  @Get("/protected")  getAdminPage() {    return "Hi! this protected info";  }
