Problem
Businesses lose competitive edge and sales by reacting too slowly to competitor price adjustments due to manual, time-consuming tracking processes.
Solution
Our service periodically scrapes specified competitor product pages, detects price changes, and dispatches instant notifications to users via webhooks, email, or internal dashboards.
Value
Ensures businesses are always aware of market dynamics, enabling rapid pricing adjustments, maximizing profitability, and maintaining a strong competitive position.
Technologies
Queues / Cron
In this idea
Competitor scraping tasks are queued and executed on a strict schedule (e.g., hourly or several times a day) to always have fresh data.
Definition
Queues and Cron are tools for running tasks on a schedule or in the background. Queues help process tasks asynchronously, keeping the main application responsive, while Cron is a classic scheduler that runs commands or scripts at specific times. Both help automate routine or resource-intensive operations like sending emails, processing data, or backups, without needing user intervention.
NestJS
In this idea
The core that coordinates all actions: launching scrapers, comparing prices, managing queues, and sending notifications.
Definition
NestJS is a framework for building efficient and scalable server-side applications using Node.js. It uses TypeScript and combines elements of object-oriented, functional, and reactive programming to make development more structured and predictable. NestJS helps organize code, simplifies integration with other libraries and tools, and is great for building both simple APIs and complex microservices.
PostgreSQL
In this idea
All important information is stored here: user settings, list of tracked products, price history, and all sent notifications.
Definition
PostgreSQL is a powerful, reliable, and object-relational database management system (RDBMS). It's known for its stability, flexibility, and adherence to SQL standards. PostgreSQL supports complex queries, transactions, foreign keys, and various data types, making it an excellent choice for applications that require data integrity and high performance, from small websites to large enterprise systems.
Webhooks
In this idea
As soon as the price of a tracked product changes, we instantly send a notification to your system (CRM, Slack, or another) without delay.
Definition
Webhooks are a way for one application to notify another application about an event that happened in real-time. Instead of constantly checking if something new has occurred, the receiving application simply waits to be notified (via webhook) over the internet. It's like getting an SMS alert when a new message arrives, rather than constantly checking your phone.
Redis
In this idea
Used for rapid temporary data storage, such as page caches to avoid constant re-scraping, and for managing task queues.
Definition
Redis is like a super-fast scratchpad for your application. Instead of writing data to a hard drive, it keeps it in the computer's main memory (RAM), making it incredibly quick to retrieve. This is perfect for things where speed is key, like caching frequently accessed information, managing user login sessions, or acting as a quick message broker to send tasks between different parts of your system.
Scrapers
In this idea
Automatically navigate competitor web pages, collecting real-time price and stock data, mimicking normal user behavior.
Definition
Scrapers are programs that automatically collect information from websites. Imagine you need to gather product prices from dozens of online stores. Instead of copying them manually, you use a scraper that visits the sites and extracts the needed data, saving it for later analysis or use.
