elastic/elasticsearch-js
Elasticsearch Js
This project is a Node.js client and database driver for Elasticsearch. It acts as a REST API wrapper that translates JavaScript method calls into HTTP requests to index, search, and manage documents within a distributed search and analytics engine.
The library provides a programmatic interface for cluster management and data integration. It includes tools for discovering cluster nodes and managing indices to maintain connection stability and organize data storage.
The client covers a broad range of operations, including document lifecycle management for CRUD actions, search query execution, and index configuration. It also handles API request authentication and permission-based access control to ensure authorized service interaction.
Features
- Elasticsearch Client Integrations - Acts as a programmatic library for connecting Node.js applications to Elasticsearch clusters for indexing and retrieval.
- Document Lifecycle Management - Implements functionality to index, retrieve, update, and delete individual documents to maintain current records.
- Elasticsearch Document CRUD - Provides a programmatic interface for performing CRUD operations on individual documents within Elasticsearch indices.
- Document Search Engines - Provides a programmatic client to retrieve specific documents from an Elasticsearch data store based on filters and search criteria.
- Search Engine APIs - Provides a programming interface to interact with, configure, and manage search engine clusters and indices.
- Elasticsearch REST APIs - Provides RESTful endpoints for configuring and querying Elasticsearch-compatible search clusters.
- Cluster Management Tools - Provides tools for discovering cluster nodes and managing indices and documents via remote connection.
- REST API Clients - Implements a client-side wrapper that interacts with Elasticsearch services using HTTP methods and JSON.
- Cluster Node Management - Programmatically manages the lifecycle and membership of cluster nodes and indices to organize data storage.
- Database Connectivity Drivers - Provides a standardized driver interface enabling applications to securely connect to and interact with the search engine.
- RESTful HTTP Interfaces - Translates programmatic JavaScript method calls into RESTful HTTP requests for database operations.
- Search Indexing - Provides capabilities to configure and organize data indices to optimize information storage and retrieval.
- Automated Node Discovery - Automatically detects and updates the list of available cluster nodes to maintain stable network connections.
- Dynamic Node Discovery - Implements automated polling of the server to maintain an updated list of active cluster nodes for connection stability.
- Middleware-Based Request Pipelines - Processes outgoing requests through modular chains of pluggable components for authentication, logging, and header manipulation.
- JSON Serialization - Provides utilities to convert JavaScript objects into JSON for network transmission and parse responses back into typed objects.
- Node.js HTTP Clients - Utilizes native Node.js http and https modules to manage network connections and data streaming to the cluster.
- API Request Authentication - Implements credential and security token verification to ensure authorized communication between the Node.js client and the remote cluster.
- Permission-Based Access Control - Validates request headers against specific permissions to authorize actions such as searching or modifying documents in the cluster.
- Stateless Architectures - Handles requests independently without maintaining server-side session state, enabling horizontal scaling across cluster nodes.
- Search Engines - Official Elasticsearch client.
