OpenSearch Client connecting to Lucenia

This TypeScript project demonstrates how to interact with Lucenia using the official OpenSearch Node.js client. It shows basic CRUD operations for both indices and documents.

Prerequisites

• Node.js
• Lucenia instance running on localhost:9200
• Basic understanding of Lucenia concepts

Setup

1. Install dependencies:

npm install

2. Configure Lucenia connection in index.ts:

const client = new opensearch.Client({
  node: 'https://localhost:9200',
  auth: {
    username: 'admin',
    password: 'myStrongPassword@123',
  },
  ssl: {
    rejectUnauthorized: false,
  },
});

Features Demonstrated

The sample code demonstrates:

• Creating an Lucenia index with custom settings
• Checking if an index exists
• Adding documents to an index
• Searching documents using match query
• Deleting documents
• Deleting indices
• Proper client cleanup

Running the Example

npx ts-node src/index.ts

Index Configuration

The example creates an index named 'books' with the following settings:

• 4 shards
• 3 replicas

Security Note

The example includes SSL verification disabled (rejectUnauthorized: false). In production environments, proper SSL configuration should be implemented.

Dependencies

• @opensearch-project/opensearch: ^3.3.0
• TypeScript: ^5.7.3
