Climate Action Data Trust User Interface

This repository provides a graphical user interface (UI) for the Climate Action Data Trust (CADT) application. CADT interfaces with the Chia Blockchain software and provides and API for entering and retrieving carbon data. This UI is a javascript application that connects to the CADT API for a convenient way to access the data.

Note that this application was previously called the Climate Warehouse UI and that name may be used interchangeably in documentation and throughout this application.

Installation

The UI application can be hosted as a web application and accessed via the browser, or as a desktop application packaged with Electron. Currently the application is only packaged for x86 platforms, though building from source is expected to work on ARM.

Desktop Applications

The releases page provides desktop applications packaged for Windows, Mac, and Debian-based Linux distributions.

Ubuntu Desktop via Apt

For Ubuntu-based Linux desktops the CADT UI is available for install with apt.

  1. Start by updating apt and allowing repository download over HTTPS:
sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
  1. Add Chia's official GPG Key (if you have installed Chia or CADT with apt, you'll have this key already and will get a message about overwriting the existing key, which is safe to do):
curl -sL https://repo.chia.net/FD39E6D3.pubkey.asc | sudo gpg --dearmor -o /usr/share/keyrings/chia.gpg
  1. Use the following command to setup the repository.
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/chia.gpg] https://repo.chia.net/cadt/debian/ stable main" | sudo tee /etc/apt/sources.list.d/cadt.list > /dev/null
  1. Install CADT-UI
sudo apt-get update
sudo apt-get install cadt-ui

Web Application

The CADT UI can be hosted as a web application, either for internal use, or made available to the public. When operating as a web application, the user's browser must be able to connect to the CADT API. This means the API must be available on the public internet if the UI is public. The READ_ONLY option on the API should be set when running a public observer node.

To host the UI on the web, use the web-build.tar.gz file from the releases page. One of the simplest solutions is to uncompress these files into a public S3 bucket. These files could also be served by any webserver, such as Nginx or Apache.

To make the CADT UI web application automatically connect to a CADT host by default, copy the config.example.json file to config.json and change the apiHost to be the CADT API hostname, including http:// and the path (everything before the /v1 part of the API URL)

Sample Nginx Config

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    # Path on disk to CADT UI files
    root /var/www/cadt-ui/build;

    # Domain name where this site will be served from
    server_name cadt-ui-example-config.com;

    # SSL certificates with full path
    ssl_certificate /path/to/ssl/certificate/fullchain.pem;
    ssl_certificate_key /path/to/ssl/certificate/privkey.pem;

    # Optional, but recommended
    resolver                  1.1.1.1;

    try_files $uri /index.html;
}

From Source

It is recommended to use the pre-built application from the releases page or the apt repo and only build from source if contributing code to the application

git clone [email protected]:Chia-Network/cadt-ui.git
cd cadt-ui
nvm install
nvm use
npm install
npm install -g git-authors-cli

npm run start

Prerequisites

You'll need:

  • Git

  • nvm

    This app uses nvm to align node versions across development, CI and production. If you're working on Windows you should consider nvm-windows

Contributing

Upon your first commit, you will automatically be added to the package.json file as a contributor.

Commiting

This repo uses a commit convention. A typical commit message might read:

    fix: correct home screen layout

The first part of this is the commit "type". The most common types are "feat" for new features, and "fix" for bugfixes. Using these commit types helps us correctly manage our version numbers and changelogs. Since our release process calculates new version numbers from our commits it is very important to get this right.

  • feat is for introducing a new feature
  • fix is for bug fixes
  • docs for documentation only changes
  • style is for code formatting only
  • refactor is for changes to code which should not be detectable by users or testers
  • test is for changes which only touch test files or related tooling
  • build is for changes which only touch our develop/release tools
  • chore is for housekeeping tasks such as hydrating from another branch

After the type and scope there should be a colon.

The "subject" of the commit follows. It should be a short indication of the change. The commit convention prefers that this is written in the present-imperative tense.

Commit linting

Each time you commit the message will be checked against these standards in a pre-commit hook. Additionally all the commits in a PR branch will be linted before it can be merged to master.
