This project is a GUI for the Block Explorer. You can use it to go through blocks, transactions, accounts, witnesses.

To run the application you have to install Node JS (18.20.0 or higher is preferable). Then after getting the repo use:

npm install

After some time you can start the application with:

npm run dev

Open http://localhost:5000 with your browser to see the result.

Right now the application is using:

• Next JS as basic framework for managing GUI, routes, env variables and so on.
• React for components and UI project.
• Tailwind for styles.
• Shadcn UI for generic presentational components.
• React Query for managing data from API.
• Typescript.
• Wax as a helping library to handle blockchain issues in applications, like formatting, assets and communication with servers

• For your issue, task or changes you want to make, create a branch. The custom branch name is USER_NAME/BRANCH_NAME
• After finishing work open PR for develop branch. If you made a lot of changes, squash the commits.
• If you're local branch is outdated, use rebase to get the newest develop.
• The maintener of Block Explorer will later merge develop into master.
• master branch is our production, develop is development staging branch.

The Block Explorer has two instances of deployment.

• https://testexplore.openhive.network – staging made from develop branch.
• https://explore.openhive.network – production made from master branch.

The deployment is done manually in pipelines.

To build a Docker image of the app run the following command:

scripts/build_instance.sh "$(pwd)"

All the options available can be displayed by running scripts/build_instance.sh --help.

To run a Docker container, use the following command:

scripts/run_instance.sh \
    --image="registry.gitlab.syncad.com/hive/block_explorer_ui:latest" \
    --api-endpoint="https://hafbe.openhive.network" \
    --hive-blog-api-endpoint="https://api.hive.blog" \
    --port="5000" \
    --name="block_explorer_ui" \
    --detach

It will start the Block Explorer UI on port 5000. The container will delete itself once stopped.

All the options available can be displayed by running scripts/run_instance.sh --help.

Alternatively, you can use the Composefile - ports will be the same as above:

pushd docker
docker compose up --detach

If you wish to change parameters (like API endpoints or port) when using the Composefile, edit the accompanying .env file

To stop and delete the container use command docker compose down.

The automatic tests are built on Playwright. To run tests use one of the following commands:

npm run pw:test:local
npm run pw:test:local:chromium
npm run pw:test:local:firefox
npm run pw:test:local:webkit

Running the tests only works locally at this moment.

There are two big part of Block Explorer that are handled by Wax library:

1. The communication with servers. See services/FetchingService.ts and types/Rest.ts. In the Rest.ts file the structure of REST API is definied both properties and responses. Every call to backend, both Hive Node and Explorer API (HAF and HAFBE) is done through Wax.
2. Formatters. Assets are changed from NAI form into formatted string. Every operation displayed in UI is formatted by our custom formatters using Wax.

1. In the root directory of the project, edit the file named .env. This file will store the environment variables needed by the application.

2. Add Required Environment Variables For Theme Colors, the application supports both light and dark theme colors. Define colors for each theme using these variables. Each color variable can be specified as an RGB value (e.g., rgb(255, 255, 255)), hex code (e.g., #FFFFFF), or named color (e.g., blue).

3. For the Light Theme Variables, set:

   REACT_APP_COLOR_BACKGROUND_START_RGB_LIGHT - Start gradient color for the background REACT_APP_COLOR_BACKGROUND_END_RGB_LIGHT - End gradient color for the background REACT_APP_COLOR_TEXT_LIGHT - Text color REACT_APP_COLOR_BACKGROUND_LIGHT - General background color REACT_APP_COLOR_ROW_EVEN_LIGHT - Color for even rows REACT_APP_COLOR_ROW_ODD_LIGHT - Color for odd rows REACT_APP_COLOR_ROW_HOVER_LIGHT - Row hover color REACT_APP_COLOR_BUTTON_LIGHT - Button color REACT_APP_COLOR_BUTTON_TEXT_LIGHT - Button text color REACT_APP_COLOR_BUTTON_HOVER_LIGHT - Button hover color REACT_APP_COLOR_SWITCH_BUTTON_LIGHT - Switch button color REACT_APP_COLOR_SWITCH_OFF_LIGHT - Switch color when off REACT_APP_COLOR_SWITCH_ON_LIGHT - Switch color when on

4. For the Dark Theme Variables, set:

   REACT_APP_COLOR_BACKGROUND_START_RGB_DARK - Start gradient color for the background in dark mode REACT_APP_COLOR_BACKGROUND_END_RGB_DARK - End gradient color for the background in dark mode REACT_APP_COLOR_TEXT_DARK - Text color in dark mode REACT_APP_COLOR_BACKGROUND_DARK - General background color in dark mode REACT_APP_COLOR_ROW_EVEN_DARK - Color for even rows in dark mode REACT_APP_COLOR_ROW_ODD_DARK - Color for odd rows in dark mode REACT_APP_COLOR_ROW_HOVER_DARK - Row hover color in dark mode REACT_APP_COLOR_BUTTON_DARK - Button color in dark mode REACT_APP_COLOR_BUTTON_TEXT_DARK - Button text color in dark mode REACT_APP_COLOR_BUTTON_HOVER_DARK - Button hover color in dark mode REACT_APP_COLOR_SWITCH_BUTTON_DARK - Switch button color in dark mode REACT_APP_COLOR_SWITCH_OFF_DARK - Switch color when off in dark mode REACT_APP_COLOR_SWITCH_ON_DARK - Switch color when on in dark mode

5. Restart the Application After adding or updating values in the .env file, restart the application to apply the changes.

Notes Do not commit your .env file to version control to avoid exposing sensitive information. You can customize the color values to suit your design needs, but be sure to follow the naming pattern provided for easy reference.
