My Image Scraper

Introduction

The project has following components that are loosely coupled:

• Html/JavaScript based front-end making ajax calls to restful APIs
• Python based scrapper service consuming a message queue
• Spring Boot based APIs that handle CRUD with Database
• PostgreSQL and RabbitMQ services encapsulated in docker images

To Use

• Front-end

user@ubuntu:~/my-scraper$ cd web-dev/
user@ubuntu:~/my-scraper/web-dev$ chmod +x runserver.sh
user@ubuntu:~/my-scraper/web-dev$ ./runserver.sh 
Serving HTTP on 0.0.0.0 port 8088 ...

• Database and Message Queue

user@ubuntu:~/my-scraper$ cd RabbitMQ/
user@ubuntu:~/my-scraper/RabbitMQ$ docker-compose up -d

user@ubuntu:~/my-scraper$ cd PostgreSQL/
user@ubuntu:~/my-scraper/PostgreSQL$ docker build -t "my-postgres" .
user@ubuntu:~/my-scraper/PostgreSQL$ docker run --name postgres1 -p 5432:5432 -d my-postgres

• Spring Boot based RESTful APIs

user@ubuntu:~/my-scraper$ gradle run

• Python Scrapper Service

user@ubuntu:~/my-scraper$ cd python2-scrapper/src
user@ubuntu:~/python2-scrapper/src$ python2 worker.py

RESTful CRUD APIs

METHODs	URL	Payload	description
GET	http://localhost:8080/scrapes	N/A	Load an array of scrapes
DELETE	http://localhost:8080/scrapes/id	N/A	Delete a scrape
POST	http://localhost:8080/scrapes	data: {url: newUrl }	Add a scrape
PATCH	http://localhost:8080/scrapes/id	data: {url: newUrl }	Update a scrape
