routing-controllers/esm2015/decorator/Param.js

Create structured, declarative and beautifully organized class-based controllers with heavy decorators usage for Express / Koa using TypeScript.

import { getMetadataArgsStorage } from '../index';
/**
 * Injects a request's route parameter value to the controller action parameter.
 * Must be applied on a controller action parameter.
 */
export function Param(name) {
    return function (object, methodName, index) {
        getMetadataArgsStorage().params.push({
            type: 'param',
            object: object,
            method: methodName,
            index: index,
            name: name,
            parse: false, // it does not make sense for Param to be parsed
            required: true, // params are always required, because if they are missing router will not match the route
            classTransform: undefined,
        });
