i want to serve this image as http://localhost/images/logo.png

How can i do this using nestjs and typescript

to serve a static image file with a specific url using nest.js and typescript, you'll need to configure a custom route in your project. follow these steps:

1. first, ensure you've installed the required packages:

```
npm i @nestjs/serve-static
```

2. next, open your `app.module.ts` file, and make the following changes:

```typescript
import { module } from '@nestjs/common';
import { servestaticmodule } from '@nestjs/serve-static';
import { join } from 'path';

// import other modules, controllers, and providers as needed

@module({
  imports: [
    servestaticmodule.forroot([
      {
        rootpath: join(__dirname, '..', 'secureimages'),
        serveroot: '/images',
      },
    ]),
    // other module imports
  ],
  controllers: [/* controllers */],
  providers: [/* providers */],
})
export class appmodule {}
```

in this code, we've imported the `servestaticmodule`, then configured it in the `imports` array. this configuration tells nest.js to serve the contents of the `secureimages` folder at the `/images` path in your url. 

3. create a middleware to modify the requested file name to the desired image file. create a file `logo-middleware.ts`:

```typescript
import { injectable, nestmiddleware } from '@nestjs/common';
import { request, response, nextfunction } from 'express';

@injectable()
export class logomiddleware implements nestmiddleware {
  use(req: request, res: response, next: nextfunction) {
    if (req.path === '/images/logo.png') {
      req.url = '/images/abc.png';
    }
    next();
  }
}
```

4. in `app.module.ts`, import and apply the newly created middleware:

```typescript
import { module, middlewareconsumer } from '@nestjs/common';
import { servestaticmodule } from '@nestjs/serve-static';
import { join } from 'path';

import { logomiddleware } from './logo-middleware';

// import other modules, controllers, and providers as needed

@module({
  imports: [
    servestaticmodule.forroot([
      {
        rootpath: join(__dirname, '..', 'secureimages'),
        serveroot: '/images',
      },
    ]),
    // other module imports
  ],
  controllers: [/* controllers */],
  providers: [/* providers */],
})
export class appmodule {
  configure(consumer: middlewareconsumer) {
    consumer.apply(logomiddleware).forroutes('*');
  }
}
```

now, when you access `http://localhost/images/logo.png`, it will serve the `abc.png` image from the `secureimages` folder.

        serveRoot: '/images',
      },
    ]),
    // Other module imports

export class LogoMiddleware implements NestMiddleware {
  use(req: Request, res: Response, next: NextFunction) {
    if (req.path === '/images/logo.png') {
      req.url = '/images/abc.png';
    }
    next();
  }
}
```

4. In `app.module.ts`, import and apply the newly created middleware:

```typescript
import { Module, MiddlewareConsumer } from '@nestjs/common';
import { ServeStaticModule } from '@nestjs/serve-static';
import { join } from 'path';

import { LogoMiddleware } from './logo-middleware';

// Import other modules, controllers, and providers as needed

@Module({
  imports: [
    ServeStaticModule.forRoot([
      {
        rootPath: join(__dirname, '..', 'secureimages'),
        serveRoot: '/images',
      },
    ]),
    // Other module imports
  ],
  controllers: [/* controllers */],
  providers: [/* providers */],
})
export class AppModule {
  configure(consumer: MiddlewareConsumer) {
    consumer.apply(LogoMiddleware).forRoutes('*');
  }
}
```

Now, when you access `http://localhost/images/logo.png`, it will serve the `abc.png` image from the `secureimages` folder.
