If you are diving into the world of EOS development, you’ve come to the right place. This guide will take you through advanced EOS contract examples that showcase a plethora of concepts that often slip through the cracks in most educational resources.

What You’ll Find Here

This collection has been updated to align perfectly with the latest release of EOSIO.CDT version 1.6. Here’s a quick list of the advanced concepts you can explore:

• Cryptographic Hashes
• Singletons
• Secondary Indexes
• Table Index Uniqueness
• One-to-many Table Relationships
• Contract-to-contract Communication
• Remote Table Access
• Deferred Transactions
• The Dispatcher Extension
• Token Transfers

Getting Started: Usage Instructions

Before you can run these examples, you’ll need to set up your environment properly. Here’s how:

1. Clone the repository:

git clone https://github.com/MitchPierias/Advanced-EOS-Examples

2. Navigate into the cloned directory:

cd Advanced-EOS-Examples

3. Install all necessary dependencies:

npm install

4. Run the tests to validate the examples:

npm run test

It may take a while to set everything up initially, as this forms Lamington’s development environment. Feel free to take a coffee break while you wait!

Understanding the Code: An Analogy

Imagine you are a chef preparing a specialty dish (your EOS contract). Each ingredient you select plays a crucial role; the spices are like the cryptographic hashes, giving your dish its unique flavor. The recipe serves as your contract’s structure, guiding you through precise steps (the coding logic).

For instance, singleton patterns act like reserved seats at a restaurant—there’s only room for one of each type at a table. Similarly, database indexing resembles a library catalog, helping you find the right book quickly amid all the titles. Just as blending different cooking techniques leads to a culinary masterpiece, combining EOS concepts leads to robust, efficient contracts.

Troubleshooting Tips

Encountering issues during setup or testing is part of the learning journey. Here are some common troubleshooting strategies:

• If Docker fails to start, ensure you have the latest version installed and running properly.
• Run tests again, sometimes a simple restart can clear up any temporary glitches.
• For mysterious errors, check the provided logs; they often contain clues for fixing the problem.
• Ensure your Node.js version is compatible with the package requirements.
