Usage

You can start the template in development mode to connect to a locally running node

yarn start

You can also build the app in production mode,

yarn build

and open build/index.html in your favorite browser.

Configuration

The template's configuration is stored in the src/config directory, with common.json being loaded first, then the environment-specific json file, and finally environment variables, with precedence.

• development.json affects the development environment
• test.json affects the test environment, triggered in yarn test command.
• production.json affects the production environment, triggered in yarn build command.

Some environment variables are read and integrated in the template config object, including:

• REACT_APP_PROVIDER_SOCKET overriding config[PROVIDER_SOCKET]
• REACT_APP_DEVELOPMENT_KEYRING overriding config[DEVELOPMENT_KEYRING]

More on React environment variables.

When writing and deploying your own front end, you should configure:

• Custom types as JSON in src/config/types.json. See Extending types.
• PROVIDER_SOCKET in src/config/production.json pointing to your own deployed node.
• DEVELOPMENT_KEYRING in src/config/common.json be set to false. See Keyring.

Specifying Connecting Node

There are two ways to specify it:

• With PROVIDER_SOCKET in {common, development, production}.json.
• With rpc=<ws or wss connection> query paramter after the URL. This overrides the above setting.
