9. Sidekiq - Simple, efficient background processing for Ruby

Architecture and components

Web Server

Provide web pages for users to use.

NFT trackers for blockchains

Track and get the NFT on the blockchains.
There are now trackers for Ethereum and Darwinia as examples.

NFT Workers

A NFT worker is a long-running process.
It is responsible for collecting the NFT discovered by the tracker and storing it in the database.
The data from the tracker is packaged into a sidekiq message for delivery.

NFT token_uri processor

It reads the token_uri of NFT from the database, and then obtains the metadata.
And, it will download and process the image from the metadata.

Models

A model is a Ruby class that is used to represent data. Additionally, models can have most of the application's logic.

1. {Account}
2. {Blockchain}
3. {Collection}
4. {Token}
5. {Property}
6. {TokenOwnership}
7. {Transfer}

The relationship between the models:

Controllers

Controllers handle the incoming web requests and eventually respond with a rendered view.

1. {WelcomeController}
2. {TokensController}
3. {CollectionsController}
4. {AccountsController}

Test

You can also test in docker container.

Preparation

1. Install Ruby ~> 2.7.0
   See Installing Ruby

2. Install ImageMagick & FFmpeg

3. Download code
   Download or clone the code to local, and go to the root directory.

4. Install Rubygems

   bundle install

Run all tests

rails test

Run a single test file

rails test test/models/transfer_test.rb

Docker

Run

1. Run mysql and redis.

docker-compose up -d db redis

2. Create tables and generate seed data.

docker-compose run --rm uniscan rails db:migrate
docker-compose run --rm uniscan rails db:seed

3. Run services

docker-compose up -d parse_token_uri update_creator 
docker-compose up -d eth_scan sidekiq uniscan

Test

1. Run mysql if not running

docker-compose up -d db

2. Create test database

docker-compose run --rm uniscan_test rails db:create
docker-compose run --rm uniscan_test rails db:migrate

3. Run tests

docker-compose run --rm uniscan rails test
