如何清除 inversifyJS 中的缓存？

Question

我有一个简单的应用程序，我使用express 服务器和TypeScript 作为编码语言。起初我可以成功到达终点，但是当我更改模型时，我看到了旧数据。

我也尝试过这种方法，但没有运气，How to disable webpage caching in ExpressJS + NodeJS?。

我在这里错过了什么？

1. 我的index.ts（主）文件

/**
 * Required External Modules
 */
import "reflect-metadata"
import * as dotenv from "dotenv";
import express from "express";
import cors from "cors";
import helmet from "helmet";
import routes from "./routes/routes";
import compress from 'compression';
const nocache = require('nocache');

dotenv.config();

/**
 * App Variables
 */
if (!process.env.PORT) {
    process.exit(1);
}

const PORT: number = parseInt(process.env.PORT as string, 10);

const app = express();

/**
 *  App Configuration
 */
app.use(helmet());
app.use(cors());
app.use(express.json());
app.disable('x-powered-by'); // Hide information
app.use(compress());
// app.disable('view cache');
// app.use((req, res, next) => {
//     res.set('Cache-Control', 'no-store')
//     next()
// })
app.use(nocache());
routes(app);

/**
 * Server Activation
 */
app.listen(PORT, () => {
    console.log(`Listening on port ${PORT}`);
});

1. route 声明。

import { Application } from "express";
import asyncWrap from "../utils/asyncWrap";
import HealthController from "../controllers/health.controller";
import container from "../ioc.container";

export default function (application: Application) {
    const healthController = container.get<HealthController>(HealthController);
 
    application.get('/healthStatus', asyncWrap(healthController.healthCheck.bind(healthController)));
}

1. asycWrap逻辑

    import { 
        Request as ExpressRequest, 
        Response as ExpressResponse, 
        NextFunction, 
    } from 'express';
    
    // Wraps async functions, catching all errors and sending them forward to express error handler
    export default function asyncWrap(controller: CallableFunction) {
        return async (req: ExpressRequest, res: ExpressResponse, next: NextFunction) => {
            try {
               await controller(req, res, next);
            } catch (e) {
                next(e);
            }
        };
    }

4. controller逻辑

import { inject, injectable } from "inversify";
import { HealthModel } from "../models/health.model";
import HealthService from "../services/health.service";
import { 
    Request as ExpressRequest, 
    Response as ExpressResponse, 
} from 'express';

@injectable()
export default class HealthController {

    constructor(
        @inject("HealthService") private HealthService: HealthService,
    ) { }

    public async healthCheck(req: ExpressRequest, res: ExpressResponse): Promise<HealthModel> {
        const returnThis = await this.HealthService.healthCheck();
        res.send(returnThis);
        return returnThis;
    }
}

5. service逻辑

import { injectable } from "inversify";
import { HealthModel } from "../models/health.model";

@injectable()
export default class HealthService {

    public async healthCheck(): Promise<HealthModel> {
        const healthModel: HealthModel = {
            dateTime: new Date(),
            description: "Hello WOrld",
            status: "sdfadfad"
        }
        return healthModel;
    }
}

6. 输出（这是我的旧结果）

Answer 1

花了将近一天的时间后，我发现我没有在更改后编译我的.ts 文件（这是我的愚蠢错误）。所以，很明显 compile 不会接受我新添加的更改。

我在package.json 中添加了start 脚本，它将编译我的.ts 文件+ 运行源文件。

这里是package.json 文件：

• 增强现实

    "scripts": {
        "dev": "ts-node-dev --respawn --pretty --transpile-only src/index.ts",
        "compile": "tsc -p .",
        "test": "jest --coverage --color",
      }

• ER

     "scripts": {
        "dev": "ts-node-dev --respawn --pretty --transpile-only src/index.ts",
        "compile": "tsc -p .",
        "test": "jest --coverage --color",
        "start": "npm run compile && npm run dev"
      }
