Detailed changelog with releases description is located in the changelog file

Development

Requirements

Minimum version of Node.js is v18.x.

Minimum version of pnpm is v8.x.

Install dependencies

To install all dependencies:

pnpm install

Husky hooks will be installed automatically after installing project dependencies:

"prepare": "husky install"

P.S. don't update pre-commit file to npm githook:pre-commit

Start in production mode

The production run configuration is the same as production build except that the application won't be installed in the operating system and source code hot-reload will be used.

Production configuration uses:

  1. chains.json file for chains configuration
  2. debug tools are disabled by default
  3. errors are handled in a smooth way in order not to interrupt the user

Use the following instructions in order to start application in the production environment with hot-reload:

Electron (desktop) environment - recommended:

pnpm start

Web (browser) environment - not recommended:

pnpm start:renderer

Start in development mode

The dev run configuration shouldn't be used for production. This configuration is only for developing new features and debugging errors.

Development configuration uses:

  1. chains_dev.json file that contains testnets in order to debug and test new features
  2. debug tools are enabled by default
  3. error handling is turned off in order to pay developer's attention to errors

Use the following instructions in order to start application in the dev environment with hot-reload:

Electron (desktop) environment - recommended:

pnpm start:dev

Web (browser) environment - not recommended:

pnpm start:renderer:dev

Project localisation

All the localisation files are stored in the /src/shared/locale folder.

ESlint checks if localisation files are well-formed and valid including:

  1. Valid json formatting
  2. Json files contain the same set of keys
  3. Each key contains the same amount of placeholders for all locales
  4. All tsx files are translated

How to run localisation check

  1. pnpm lint:i18n-locale checks if localization files are well-formed and valid
  2. pnpm lint:i18n-fix fixes the keys sorting order
  3. pnpm lint:i18n-tsx checks if tsx files are translated

How to ignore localisation errors

In some cases there is no need to translate the text, so ESlint ignore rules should be used.

<span className="font-bold">
  {/* eslint-disable-next-line i18next/no-literal-string */}
  {data?.asset.symbol} ({data?.asset.name})
</span>

or

//eslint-disable-next-line i18next/no-literal-string
const qrCodePayload = `substrate:${address}:${wallet.accountId}`;

Production build

To package application for the local platform:

pnpm build
pnpm postbuild
pnpm dist
