Provides a Node.js wrapper that abstracts Azure OpenAI service authentication and endpoint configuration, handling credential injection through environment variables or explicit parameters. The library manages the underlying HTTP client setup for communicating with Azure's OpenAI endpoints, eliminating boilerplate for developers who would otherwise need to manually construct Azure SDK clients or raw HTTP requests.
Unique: Provides a lightweight Node.js-specific wrapper around Azure OpenAI endpoints, abstracting Azure SDK complexity while maintaining compatibility with Azure's credential patterns (API keys, Managed Identity). Unlike the official @azure/openai SDK, this library prioritizes simplicity for common use cases.
vs alternatives: Simpler API surface than @azure/openai for basic chat/completion workflows, but less feature-complete for advanced Azure-specific scenarios like managed identity or VNet integration
Executes chat completion requests against Azure OpenAI deployments, supporting both blocking (await response) and streaming (event-based token delivery) modes. The library marshals message arrays into Azure's expected format, handles response parsing, and optionally streams tokens back to the caller via Node.js readable streams or callback patterns, enabling real-time UI updates or token-by-token processing.
Unique: Abstracts Azure OpenAI's HTTP streaming protocol into Node.js-native readable streams, allowing developers to pipe responses directly to HTTP response objects or process tokens with standard Node.js stream utilities. Handles Azure's specific response envelope format without exposing raw HTTP details.
vs alternatives: More lightweight than @azure/openai for streaming use cases, with simpler callback-based APIs, but lacks built-in error recovery and token counting that enterprise libraries provide
Executes text completion requests (non-chat) against Azure OpenAI deployments, supporting legacy GPT-3 models and fine-tuned completions. The library formats prompt strings into Azure's completion API format, handles response parsing, and returns completion choices with finish reasons, enabling use cases that don't fit the chat paradigm (code generation from raw prompts, text continuation, few-shot learning).
Unique: Provides a direct wrapper around Azure's completion endpoint, preserving the raw prompt-to-text paradigm without forcing chat message structure. Useful for teams with existing prompt-based workflows that haven't migrated to chat models.
vs alternatives: Simpler than OpenAI's official SDK for completion-only workflows, but less maintained as the industry shifts to chat completions
Generates vector embeddings for text inputs using Azure OpenAI's embedding models (text-embedding-ada-002 or similar). The library batches text inputs, calls the Azure embedding endpoint, and returns normalized vectors suitable for vector database storage or similarity computations. Embeddings enable semantic search, clustering, and recommendation workflows without requiring separate embedding infrastructure.
Unique: Wraps Azure OpenAI's embedding endpoint with simple array-based input/output, abstracting HTTP request formatting. Handles Azure's specific embedding response envelope without exposing raw API details.
vs alternatives: Simpler API than @azure/openai for embedding workflows, but no built-in batching optimization or caching that specialized embedding libraries provide
Allows developers to specify which Azure OpenAI deployment and model version to use for requests, abstracting the mapping between deployment names and underlying models. The library routes requests to the correct Azure endpoint based on deployment configuration, enabling multi-model setups (e.g., different deployments for chat vs embeddings) and A/B testing across model versions without code changes.
Unique: Abstracts Azure's deployment-based routing model, allowing developers to treat deployments as interchangeable endpoints. Unlike OpenAI's single-model-per-API-key approach, Azure requires explicit deployment selection, and this library simplifies that pattern.
vs alternatives: Cleaner than manually constructing Azure endpoints, but less sophisticated than frameworks that provide automatic failover or load balancing across deployments
Catches Azure OpenAI API errors (rate limits, authentication failures, model unavailability) and maps them to meaningful exception types or error objects, preserving Azure error codes and messages. The library distinguishes between transient errors (429, 500) and permanent failures (401, 404), enabling developers to implement appropriate retry logic or user-facing error messages without parsing raw HTTP status codes.
Unique: Maps Azure-specific HTTP status codes and error response envelopes into semantic error types, allowing developers to handle Azure failures without parsing raw responses. Preserves Azure error codes for correlation with Azure monitoring tools.
vs alternatives: More Azure-aware than generic HTTP client error handling, but less sophisticated than dedicated resilience libraries (Polly, node-retry) that provide automatic retry strategies
Validates input parameters (temperature, max_tokens, top_p, etc.) against Azure OpenAI API constraints before sending requests, rejecting invalid values early with descriptive error messages. The library enforces parameter bounds (e.g., temperature 0-2, max_tokens within model limits) and type checking, preventing malformed requests from reaching Azure and reducing API call failures.
Unique: Implements client-side parameter validation against Azure OpenAI's documented constraints, catching errors before network round-trips. Reduces API call failures and provides immediate feedback during development.
vs alternatives: Faster feedback than server-side validation, but less authoritative than Azure's actual API constraints which may differ from documented limits
Crawls 11+ heterogeneous platforms (Zhihu, Weibo, Bilibili, Twitter, Reddit, HackerNews, etc.) and RSS feeds using platform-specific scrapers, normalizes disparate data schemas into a unified NewsItem model, and deduplicates content across sources using fuzzy title matching and URL canonicalization. The system maintains platform-specific metadata (rank, heat value, engagement metrics) while presenting a single normalized feed, enabling cross-platform trend detection that would be invisible within individual platform silos.
Unique: Implements platform-specific crawler modules with unified NewsItem schema and fuzzy deduplication across 11+ heterogeneous sources (Chinese + international), rather than relying on single-platform APIs or generic RSS parsing. Maintains platform-specific metadata (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) for weighted hotspot scoring.
vs alternatives: Covers more platforms (especially Chinese social media) with deeper metadata extraction than generic RSS aggregators, and provides unified deduplication across sources unlike single-platform monitoring tools.
Implements a multi-stage filtering pipeline that matches news items against user-defined keywords using regex patterns, required word lists, and excluded word lists. The system applies frequency-based scoring (keyword occurrence count) combined with platform hotspot weights to rank filtered results. Configuration is stored in frequency_words.txt with support for regex patterns, AND/OR/NOT boolean operators, and per-keyword weighting. Filtering occurs at collection time (reducing storage) and again at report generation time (enabling dynamic reconfiguration without re-crawling).
Unique: Combines regex pattern matching with frequency-based scoring and platform hotspot weighting (rank × 0.6 + frequency × 0.3 + platform hot value × 0.1) in a two-stage pipeline (collection-time and report-time filtering). Supports dynamic reconfiguration without re-crawling by applying filters at report generation.
TrendRadar scores higher at 58/100 vs azure-openai at 31/100.

Search the match graph →© 2026 Unfragile. Stronger through disorder.
vs alternatives: More flexible than simple keyword matching (supports regex and boolean logic) and more efficient than semantic filtering (no LLM overhead), making it suitable for real-time filtering at scale.
Detects newly emerged topics by comparing current crawl results against historical data stored in the system. Topics are marked as 🆕 (new) if they appear for the first time in the current crawl or if their hotspot rank increased significantly compared to previous crawls. The system tracks topic emergence velocity (how quickly a topic rises in rankings) and flags topics with unusual acceleration. New topic detection is performed at report generation time, enabling dynamic detection without re-crawling. The system maintains a historical hotspot index for comparison.
Unique: Detects new topics by comparing current hotspot rankings against historical data, marking topics with significant rank increases as 🆕. Tracks emergence velocity to distinguish breaking news from sustained trends.
vs alternatives: More efficient than semantic similarity detection (no LLM overhead) and more accurate than simple first-appearance detection (accounts for re-emerging topics), but requires historical baseline data.
Provides a web-based UI for editing TrendRadar configuration files (config.yaml, frequency_words.txt, timeline.yaml) with real-time validation and preview. The editor supports: (1) syntax highlighting for YAML and regex, (2) validation of keyword patterns (regex compilation check), (3) preview of filtered results based on current keyword configuration, (4) drag-and-drop channel configuration, (5) schedule preview (shows next 10 execution times). Changes are validated before saving, preventing configuration errors. The editor is optional; users can edit config files directly.
Unique: Provides web-based configuration editor with real-time validation, regex preview, and schedule visualization. Enables non-technical users to configure TrendRadar without editing YAML files.
vs alternatives: More user-friendly than manual YAML editing and provides validation feedback, but adds operational complexity compared to file-based configuration.
Integrates LiteLLM to provide vendor-agnostic AI analysis and summarization of filtered news items. Users configure their preferred LLM provider (OpenAI, Anthropic, Ollama, local models, etc.) once in config.yaml, and the system automatically routes analysis requests to that provider. The AI analysis capability includes: (1) automated summarization of long articles into key points, (2) sentiment analysis (positive/negative/neutral), (3) trend prediction based on historical patterns, and (4) custom analysis prompts. Analysis results are cached to avoid redundant API calls and can be pushed directly to notification channels.
Unique: Uses LiteLLM abstraction layer to support any LLM provider (OpenAI, Anthropic, Ollama, local models) with single configuration, enabling provider switching without code changes. Caches analysis results to reduce redundant API calls and costs.
vs alternatives: More flexible than hardcoded OpenAI integration (supports any LiteLLM provider) and cheaper than dedicated sentiment analysis APIs (can use local models), but slower than rule-based sentiment analysis.
Leverages LiteLLM to translate news content from source languages (primarily Chinese) to target languages (English, etc.) on-demand. The system detects source language automatically (via langdetect or similar), caches translations to avoid re-translating identical content, and batches translation requests to reduce API calls. Translations are stored alongside original content, enabling bilingual reports and multi-language notification delivery. Translation can be triggered at collection time (all news) or report time (only filtered news).
Unique: Implements provider-agnostic translation via LiteLLM with automatic language detection, content-based caching, and batch request optimization. Stores translations alongside originals for bilingual report generation.
vs alternatives: More flexible than dedicated translation APIs (supports any LiteLLM provider) and cheaper than commercial translation services when using local models, but slower than specialized translation APIs.
Implements a notification abstraction layer supporting 9+ delivery channels (WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc.). Each channel has a provider-specific formatter that converts normalized news items into channel-appropriate messages (e.g., WeChat card format, Telegram markdown, email HTML). The system batches notifications atomically—all news items for a report are sent as a single batch to each channel, ensuring consistency and reducing API calls. Message formatting respects channel constraints (character limits, attachment limits, etc.) and supports templating for customization.
Unique: Implements atomic message batching across 9+ heterogeneous channels with provider-specific formatters and constraint-aware truncation. Single configuration enables simultaneous delivery to WeChat, WeWork, Feishu, Telegram, Email, ntfy, Bark, Slack, etc. without code changes.
vs alternatives: Supports more channels (especially Chinese platforms like WeWork, Feishu) than generic notification services, and batching reduces API calls and spam compared to per-item notifications.
Exposes TrendRadar's data and analysis capabilities as an MCP server, enabling AI agents and LLM applications to query trends, perform analysis, and generate insights through natural language. The MCP server implements tools for: (1) querying filtered news by keyword/date/platform, (2) retrieving trend statistics and hotspot rankings, (3) running custom analysis on news subsets, (4) generating reports in various formats. Clients (Claude, other LLM agents) can invoke these tools via MCP protocol, enabling conversational exploration of trends without direct database access. The server maintains state across multiple requests, allowing multi-turn conversations about trends.
Unique: Implements full MCP server exposing trend data and analysis tools to LLM agents, enabling conversational queries and multi-turn analysis workflows. Maintains state across requests and supports complex tool invocations (filtering, analysis, report generation).
vs alternatives: Enables conversational access to trends (vs. API-only access) and integrates with LLM agent workflows (vs. standalone tools), but adds operational complexity compared to simple REST APIs.
