Usage

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