Node Oauth2 Server
node-oauth2-server is an OAuth2 server implementation for Node.js that functions as an authorization provider. It enables the creation of a centralized server to manage client registration and issue access tokens for third-party applications using the OAuth2 protocol.
The project operates as Node.js middleware, integrating authorization logic directly into web application request pipelines. It provides a bearer token validator to verify identity and permissions by checking security tokens within incoming HTTP request headers.
The system covers API access control, token management, and user authorization workflows. It handles the generation, storage, and validation of access and refresh tokens, including scope-based access control to restrict resource access based on defined user permissions.
Features
- OAuth2 Access Token Issuance - Generates short-lived access tokens using various OAuth2 grant types to control resource access.
- API Access Scopes - Enforces granular API access by comparing requested scopes against granted token permissions.
- Request Token Validators - Verifies that incoming authorization tokens are active and authorized before granting access.
- Access and Refresh Token Issuances - Manages the generation, storage, and expiration of both access and refresh tokens.
- API Access Control - Secures web endpoints by validating bearer tokens to restrict access to authorized clients.
- Bearer Token Authentication - Validates bearer tokens in request headers to authenticate API requests.
- Third-Party Account Authorizations - Facilitates the workflow where users grant third-party applications limited access to their accounts.
- OAuth2 Implementations - Implements a centralized OAuth2 server to issue and manage access tokens for third-party applications.
- OAuth2 Providers - Functions as an OAuth2 provider managing client registration, token persistence, and scope control.
- Bearer Token Validators - Provides a mechanism to verify identity and permissions via bearer tokens in HTTP headers.
- Request Interception Middlewares - Provides middleware that intercepts HTTP requests to verify bearer tokens before routing.
- Model Persistence Layers - Delegates data persistence to user-defined model objects to remain database-agnostic.
- Authorization Data Writings - Stores client, token, and user authorization data within a persistent database system.
- Token Lifecycle Management - Manages the lifecycle of authorization grants, including creation and expiration timestamps.
- Multi-Grant Type Flows - Implements multiple OAuth2 grant type flows to handle various token issuance requirements.
- Interface-Driven Component Models - Uses strict interface contracts for data models to ensure compatibility with the authorization server.
- Authorization Middlewares - Integrates authorization logic directly into Node.js web application request pipelines as middleware.
