# 🗑 deleteLoader

The `deleteLoader()` method allows you to delete the data loaded by a loader previously added to the app.

### Parameters

<ParamField path="uniqueLoaderId" type="string" required>
  The loader unique id that is generated when the loader is added to the app.
</ParamField>

### Usage

```ts theme={null}
import { RAGApplicationBuilder } from '@llm-tools/embedjs';
import { OpenAiEmbeddings } from '@llm-tools/embedjs-openai';
import { HNSWDb } from '@llm-tools/embedjs-hnswlib';
import { RedisStore } from '@llm-tools/embedjs-redis';
import { WebLoader } from '@llm-tools/embedjs-loader-web';
import { SitemapLoader } from '@llm-tools/embedjs-loader-sitemap';

const app = await new RAGApplicationBuilder()
.setModel(SIMPLE_MODELS.OPENAI_GPT4_O)
.setEmbeddingModel(new OpenAiEmbeddings())
.setVectorDatabase(new HNSWDb())
.setStore(
    new RedisStore({
        host: this.configService.get('REDIS_HOST'),
        port: this.configService.get('REDIS_PORT'),
        password: this.configService.get('REDIS_PASSWORD'),
    }),
)
.build();

const { uniqueId: forbesId } = await app.addLoader(new WebLoader({ urlOrContent: 'https://www.forbes.com/profile/elon-musk' }));
const { uniqueId: sitemapId } = await app.addLoader(new SitemapLoader({ url: '"https://js.langchain.com/sitemap.xml' }));

await app.deleteLoader(forbesId);
```

<Note>
  If you do not have the uniqueId, you can use `app.getLoaders()` method to get all the loaders and extract the `uniqueId` from it.
