Electoral Council election results management system - Frontend

Development

Prerequisites

Building

Install JavaScript dependencies:

npm install

Install Playwright dependencies:

npx playwright install --with-deps --no-shell

Running

This runs the client with a (client-side) mock API:

npm run dev

To run with the backend API server, first start the API server and use:

npm run dev:server

Linting

npm run lint

Testing

Unit tests

npm run test

Browser tests using Playwright:

# tests for ui components using ladle:
npm run e2e:lib-ui

# tests for frontend with msw:
npm run e2e:app

# tests for frontend with backend and database
# tests use database at backend/target/debug/playwright.sqlite
# build frontend, build backend, setup fresh seeded database:
npm run e2e:d2d
# run tests, expect builds and database to be available:
npm run e2e:d2d-dev

UI Component development

Develop and test UI components in isolation:

npm run ladle

And open Ladle at http://localhost:61000/.

  • msw: Mock Service Worker for mocking the server, client side
  • vite: frontend build tool
  • ladle: simple development and test environment for UI components
  • postcss and autoprefixer: CSS post processors
  • lefthook: git hook automation
  • cross-env: for building on Windows

Testing / linting dependencies

  • vitest: Jest compatible unit test framework
  • jsdom: a pure-JavaScript implementation of many web standards for use with Node.js
  • testing-library: (React) component and dom test utilities
  • playwright: e2e testing framework

Scripts

gen_openapi_types

Generate Typescript types from /backend/openapi.json:

npm run gen:openapi

This results in /frontend/lib/api/gen/openapi.ts.

gen_icons

Generate React components from icons located in /frontend/lib/ui/svg:

npm run gen:icons

This results in /frontend/lib/icon/gen.tsx.

gen_po

Use this script to create .po files (one for every defined locale) that can de used in translation software. This script generates .po translation files from the current json translations in /frontend/lib/i18n/loclales/<locale>/*.json:

npm run gen:po

This results in /frontend/translations/<locale>.po. These can be imported into translation software.

gen_translation-json

Use this script to convert modified .po files back to our application json translation files. This script generates json translation files from .po translation files in /frontend/translations/<locale>.po:

npm run gen:translation-json

This results in /frontend/lib/i18n/loclales/<locale>/*.json. These contain the texts used by the application.
