The following information will provide all the details necessary to set up an instance of ARKScan for a development environment. Developers should ideally possess the requisite knowledge regarding the configuration and handling of databases as well as experience working in both PHP and Laravel environments. Further to this, a working knowledge of PHP 8, Composer, and Valet should make the setup process significantly easier.
ARKScan requires two separate databases, namely a Core database that serves data to ARKScan, and another for local storage of additional data (such as forging statistics, for instance).
In order to successfully carry out a development installation of ARKScan, you will need to download and install the following before proceeding further:
The following instructions will guide you through the setup and configuration process using Valet . Other methods of installation will follow a similar approach, but some steps may not necessarily coincide with the instructions detailed here.
Clone the Repository - To begin, enter the following command to clone the ARKScan repository and wait for it to copy all the necessary files onto your system.
1git clone ssh://github.com/ArkEcosystem/explorer.git
Install Dependencies -
cd into your ARKScan folder and run the relevant commands to install the necessary Composer and Yarn dependencies. Bear in mind that this process may take several minutes to complete depending on your location and/or internet connection.
1cd explorer2composer install --ignore-platform-reqs3yarn
Prepare the Application
Generate the Environment - Run the following command to create a copy of the default environment variables for ARKScan. This will generate a
.env file containing some of the necessary data you will require for your development instance. Naturally you will need to configure some parameters in accordance with your unique setup, but we will cover this in Adjust Environment Variables.
1cp .env.example .env
Create a Database - As mentioned earlier, ARKScan requires two databases, one of which is a local database for forging statistics. By default, the
.env file is configured to use SQlite via the
DB_CONNECTION=sqlite setting. As such, the default database name it will look for is
database.sqlite, so create the necessary file by running
While SQLite will work, it is also possible to use PostgreSQL. To learn more about how to set up a PostgreSQL database, click here.
Adjust Environment Variables
Configure the Environment - You will then need to edit the parameters in your
.env so that it uses both of your databases. With regards to your local database, if you created a
database.sqlite file, there is no need to make any further adjustments since the default value is
DB_CONNECTION=sqlite. However, if you set up a database using PostgreSQL, you will need to alter the parameters accordingly:
The next step involves setting the parameters for your core database. You will need to fill in the necessary details for either a local connection or a PostgreSQL database. Regardless of which applies to your installation, you will use the exact same environment variables but enter in any values that apply to your particular database.
1ARKSCAN_NETWORK=development2ARKSCAN_DB_HOST=127.0.0.1 for local, or an ip address for remote3ARKSCAN_DB_PORT=54324ARKSCAN_DB_DATABASE=<your-database-name>5ARKSCAN_DB_USERNAME=<your-username>6ARKSCAN_DB_PASSWORD=<your-password>
In addition to the above, ensure that the
CACHE_DRIVER= is set to
redis (the current default is
Generate Placeholder Data (Only for Local Testing)
This section is only relevant if you wish to access local testing data. In other words, if your
.env configuration points to a core node, ignore this section and complete your setup accordingly.
Use the following two commands in order to generate placeholder data if you do not have access to a Core Node Database. Note that the
ARKSCAN_DB_DATABASE= variable must match the exact name of your database or your instance of ARKScan will fail to run. Also note that you will need to set up a PostgreSQL database and adjust your
.env to point to it.
Generate Placeholder Data - (Remember to only execute these commands if required).
1php artisan migrate --path=tests/migrations --database=explorer2composer play
Further Information Regarding Environment Variables
ARKScan makes use of telescope, debugbar and response cache, each of which possesses its own
.env variables to adjust during development. As such, you can enable or disable these according to your needs by modifying the following parameters:
In addition to the above, several custom variables apply to ARKScan. Naturally you may configure these according to your unique requirements. The following list outlines some of the more important aspects in greater detail.
- The default value for Dark Mode is set to
truesince ARKScan comes with a custom Dark Mode UI. However, if you wish to disable it, you can do so here.
- When making use of the QR code that generates on Wallet Detail pages, a URI will prefix it. As such, you may define which URI to use in order to make it compatible with other applications. The default value here is set to
arkas this works with the ARK-branded wallet.
- The default for ARKScan is set to a development network. You may change this to a production environment by replacing
productionfor instance. You might want to use custom environment variables, but only
productionexist by default. Should you require a custom network, you can inspect the available network variables in the configuration file. You may then set these in your
.envfile, or you can adjust or extend the options therein.
- ARKScan makes use of coingecko to obtain its data. Should you wish to use a different market data provider, you may implement your own class and configure your
.envfile to use that instead. Bear in mind that that you will need to add your market data provider implementation in the code. You can view examples in the
app/Services/MarketDataProvidersfolder along with the corresponding interface it must implement.
Complete the Setup
Generate an Application Key - Run the following command to set the
APP_KEY value in your
1php artisan key:generate
If no database exists, running the
php artisan key:generate command will result in an error.
Set up Your Local Database - Run the following command to set up your local database to store delegate forging statistics.
1php artisan migrate:fresh
Start Horizon and Cache All Required Data - Having set up your databases, run the first of the following commands to start Horizon. Then run the second command to cache all the required data for ARKScan.
1php artisan horizon2php artisan explorer:cache-development-data
Create Symlink and Enable Hot Reloading - Run the first of the following commands to create a symlink to your
public folder. When this completes, execute the second command so that any changes you make to the UI will reflect during the development process.
1php artisan storage:link2yarn watch
Create Symbolic Link - Finally, run this command to link Valet so that your instance of ARKScan will appear in your browser.
1valet link explorer
Having finalized this step, navigate to
arkscan.test in your browser. If everything went as intended, you should see all the relevant data clearly displayed on the UI.
An additional database stores missed blocks in order to derive performance metrics for delegates. These values represent the average performance levels based on data from the past 30 days. To generate them for the first time you run ARKScan, execute the command
php artisan explorer:forging-stats:build --days=30.
The initial calculation may take a while to run, but scheduled jobs append new values once storage of the initial 30 days has taken place.
You can create a vote report text file by executing the
explorer:generate-vote-report command. By default, this process runs every 5 minutes.
