Epirus Substrate UI

Epirus Substrate UI is the user interface for Epirus squids.

To enable contract source code verification capabilities you will need a running instance of the Ink! Verifier Server.

Configuration

To configure the UI just create a .env file with the configuration variables.

Example

# =================================
# Substrate UI config.
# =================================

# Port of the development server
PORT=3300

# Epirus Squid Ink query service endpoint
REACT_APP_SQUID_ENDPOINT=http://localhost:4350/graphql
# Epirus Squid Archive query service endpoint
REACT_APP_SQUID_ARCHIVE_ENDPOINT=http://localhost:4445/graphql
# Source code verification
REACT_APP_SOURCE_CODE_ENABLED=false
REACT_APP_VERIFIER_ENDPOINT=http://127.0.0.1:3001
REACT_APP_VERIFIER_WS_ENDPOINT=ws://127.0.0.1:3001

# EOF

See .env.example for reference.

Head to Adding custom environment variables for further details.

Running locally

After installing the project dependencies, only for the first time, using

npm i

you can start a development server

npm start

Testing

To run the unit tests, use the command

npm test

To generate a test coverage report, execute

npm run test:coverage

Linting

To apply the code linter and automatically fix issues

npm run lint:fix

Analysis

To generate a source code map analysis

npm run analysis

Will generate an HTML report in .analysis/source-map.html

Quite useful to tackle down the cause of big sizes in production build artifacts.

Container Image

docker build -t epirus-substrate-ui:develop .

The build process copies the .env.example environment configuration as required by Runtime ENV CRA. Note that NODE_ENV=development does not resolve process.env variables. See Runtime ENV CRA project for details.

Others

This project was bootstrapped using CRA for convinience. We are using CRACO to enable PostCSS nesting capabilities in TailwindCSS without ejecting.
