Description
Overview
This project metrics aggregation workflow automates the collection and updating of software project statistics, functioning as a real-time orchestration pipeline. Designed for developers and project managers, it consolidates data from multiple sources including Product Hunt, npm, Docker Hub, and GitHub, using a cron-triggered automation workflow that runs every minute.
By integrating varied platform APIs, it deterministically fetches and formats key metrics before pushing them to a centralized dashboard via authenticated HTTP POST requests, ensuring synchronized updates and consistent data presentation.
Key Benefits
- Runs automatically every minute via a cron-triggered automation workflow for continuous updates.
- Aggregates project metrics from Product Hunt, npm, Docker Hub, and GitHub in one orchestration pipeline.
- Formats and normalizes raw data with function nodes for consistent, human-readable dashboard display.
- Uses authenticated HTTP POST requests to securely update multiple dashboard widgets in real time.
Product Overview
This automation workflow initiates with a cron node set to trigger every minute, executing a sequence of data retrieval and processing operations. It first establishes static configuration parameters including dashboard endpoint, authentication token, and identifiers for Product Hunt, npm, Docker, and GitHub resources using a set node. The workflow then concurrently fetches data from four external APIs: Product Hunt via GraphQL POST request, npms.io for npm package metrics, Docker Hub REST API for image stats, and GitHub API for repository details.
Each data source’s raw response is passed through dedicated function nodes that parse, format, and add thousands separators to numeric fields such as star counts, pull counts, and review metrics. Following data normalization, the workflow sends multiple HTTP POST requests to update corresponding widgets on a custom dashboard, using the configured authentication token for secure API access. Error handling is managed by n8n’s platform defaults without explicit retries or backoff logic defined. The entire process operates synchronously within each cron cycle, producing a stable and up-to-date metrics feed for dashboard visualization without data persistence outside runtime memory.
Features and Outcomes
Core Automation
This automation workflow accepts a scheduled cron trigger every minute to orchestrate multi-source data retrieval and processing. It employs function nodes for deterministic data formatting and branches requests to update dashboard widgets.
- Single-pass evaluation of all external data sources per cycle.
- Consistent data normalization with custom function transformations.
- Synchronous execution ensures completeness before next trigger.
Integrations and Intake
The orchestration pipeline integrates four external APIs: Product Hunt GraphQL API, npms.io REST API, Docker Hub REST API, and GitHub REST API. Authentication is handled via bearer tokens or API tokens as required by each platform.
- Product Hunt API fetches post metrics with required post ID and bearer token.
- npm metrics retrieved from npms.io with User-Agent header for package data.
- Docker Hub and GitHub data accessed via HTTP requests and GitHub node respectively.
Outputs and Consumption
The processed metrics are output as JSON payloads via authenticated HTTP POST requests to specific dashboard widget endpoints. The workflow updates multiple widgets synchronously with formatted values for direct dashboard consumption.
- Widget updates include metrics like stars, pulls, reviews, votes, and issue counts.
- Payloads contain human-readable strings with thousands separators for clarity.
- Each widget update is an individual HTTP POST ensuring modular data delivery.
Workflow — End-to-End Execution
Step 1: Trigger
The workflow initiates via a cron node configured to trigger every minute, ensuring continuous and timely execution. No additional headers or fields are required at the trigger stage.
Step 2: Processing
After trigger, a set node configures static project and authentication parameters used throughout the flow. Incoming data from external APIs undergoes parsing and formatting via function nodes which apply numeric rounding and insertion of thousands separators. Basic presence checks are performed, and data is passed through unchanged when no transformation is needed.
Step 3: Analysis
This workflow does not implement conditional logic or thresholds. Instead, it deterministically formats and normalizes raw metrics from multiple sources in preparation for dispatch. No decision branches or error corrections are configured beyond standard n8n error handling.
Step 4: Delivery
Processed metrics are sent via multiple HTTP POST requests to corresponding dashboard widget endpoints. Each request includes an authentication token and the current metric value. Delivery is synchronous within the workflow execution, ensuring all widget data is updated before the next trigger cycle.
Use Cases
Scenario 1
A project manager needs up-to-date community engagement metrics aggregated from diverse platforms. This automation workflow collects, formats, and centralizes these metrics every minute, providing a reliable, centralized view without manual data entry.
Scenario 2
Developers monitoring package health want real-time npm quality, popularity, and maintenance scores. The workflow retrieves these scores from npms.io, formats the results, and updates a dashboard, enabling continuous insight into package status.
Scenario 3
An open-source maintainer requires synchronized GitHub and Docker statistics shown on a custom dashboard. This orchestration pipeline automates data retrieval and posting, eliminating manual synchronization and ensuring accuracy in reported repository activity.
How to use
To deploy this automation workflow, import it into your n8n instance and configure the dashboard hostname, authentication token, and relevant project identifiers within the set node. Insert your Product Hunt API bearer token in the designated HTTP request node. Ensure GitHub credentials are provided if authenticated access is required. Once configured, activate the workflow to run every minute, automatically fetching and updating metrics on your dashboard. Expect formatted numeric outputs such as star counts and votes to be updated in near real-time, facilitating continuous project monitoring.
