```

ELLER

```bash

```

### Lint

```bash
npx nx run twenty-front:lint # pass --fix to fix lint errors
```

## Oversættelser

```bash
npx nx run twenty-front:lingui:extract
npx nx run twenty-front:lingui:compile
```

### Test

```bash
npx nx run twenty-front:test # run jest tests
npx nx run twenty-front:storybook:serve:dev # run storybook
npx nx run twenty-front:storybook:test # run tests # (needs yarn storybook:serve:dev to be running)
npx nx run twenty-front:storybook:coverage # (needs yarn storybook:serve:dev to be running)

## Tek Stack

Projektet har en ren og simpel stack, med minimal boilerplate kode.

**App**

- [React](https://react.dev/)
- [Apollo](https://www.apollographql.com/docs/)
- [GraphQL Codegen](https://the-guild.dev/graphql/codegen)
- [Recoil](https://recoiljs.org/docs/introduction/core-concepts)
- [TypeScript](https://www.typescriptlang.org/)

**Testning**

- [Jest](https://jestjs.io/)
- [Storybook](https://storybook.js.org/)

**Værktøjer**

- [Yarn](https://yarnpkg.com/)
- [Craco](https://craco.js.org/docs/)
- [ESLint](https://eslint.org/)

## Arkitektur

### Routing

[React Router](https://reactrouter.com/) håndterer rutingen.

For at undgå unødvendige [re-renders](/l/da/developers/frontend-development/best-practices-front#managing-re-renders) er al rutelogik i en `useEffect` i `PageChangeEffect`.

### State Management

[Recoil](https://recoiljs.org/docs/introduction/core-concepts) håndterer tilstandsadministration.

Se [best practices](/l/da/developers/frontend-development/best-practices-front#state-management) for mere information om tilstandsadministration.

## Testning

[Jest](https://jestjs.io/) bruges som værktøj til enhedstest, mens [Storybook](https://storybook.js.org/) er til komponenttest.

Jest er primært til test af hjælpefunktioner, og ikke komponenterne selv.

Storybook er til at teste opførselen af isolerede komponenter, samt vise design systemet.
