Welcome to the world of Subscan Essentials, a powerful blockchain explorer scaffold project aimed at supporting substrate-based blockchain networks. This article will walk you through the essential steps to set it up, troubleshoot common issues, and help you get started with developing your own unique applications.

Features of Subscan Essentials

• Support for Substrate network custom type registration
• Indexing capabilities for Block, Extrinsic, Event, and Logs
• Custom plugins for extended indexing
• Automatic plugin template generation with the Gen tool
• Built-in default HTTP API documentation

Quick Start

Let’s dive right into the setup process! Below are the prerequisites, installation instructions, and basic configurations necessary to get you started.

Requirements

• Linux or Mac OSX
• Git
• Golang 1.12.4+
• Redis 3.0.4+
• MySQL 5.6+
• Node 8.9.0+

Installation Steps

• Run the build script:

bash build.sh

• Build the UI and navigate to it:

cd ui && yarn && yarn dev

User Interface (UI)

The UI of Subscan Essentials is built with nuxt.js and amis. To customize it, update your nuxt.config.js file to change the proxy target to your server:

proxy: {
    api: {
        target: 'https://your_server_name.com',
        secure: false,
        changeOrigin: true,
        pathRewrite: {'^api': 'api'}
    }
}

Configuration

After the installation, initiate the config file with:

bash cp configs/config.yaml.example configs/config.yaml

Then, configure Redis, MySQL, and HTTP server details based on your requirements.

Usage Instructions

Make sure to start your Redis and MySQL services before proceeding. To run the Subscan service, use the following commands:

bash
cd cmd/subscan
bash subscan start substrate

Using Docker for Quick Setup

If Docker is your preferred method, use docker-compose to quickly start projects:

docker network create app_net
docker-compose -f docker-compose.db.yml up -d
docker-compose build
docker-compose up -d

Troubleshooting Common Issues

While following the steps above, you may encounter some common issues. Here are troubleshooting tips to help you:

• Redis or MySQL not starting? Ensure that they are installed and correctly configured.
• UI won’t load? Check that the development server is running and verify your nuxt.config.js settings.
• Database connection errors? Double-check your MySQL credentials and the database name specified in the configuration.
