Case 2: Share rendering only, yet business login behind is different
// ./app/components/Profile/_ProfileLayout.js
const Presenter = ({name, age, clazz, children}) => (
<div>
<span class="name">{name}</span>
<span class="age">{age}</span>
<span class="clazz">{clazz}</span>
{...children}
</div>
)
const Translated = translate('AcccountViewer')(Presenter);
export default Translated;
// ./app/components/Profile/StudentProfile.js
import ProfileLayout from './_ProfileLayout';
import { goToClub } from '../actions';
import { getStudentByProfileId } from '../selectors';
const Presenter = ({clubs_joined, t, goToClub}) => (
<ProfileLayout>
{clubs_joined && clubs_joined.map((club) =>
<Link onClick={() => goToClub(club)}>
<span>{t('JOIN_A_CLUB', club)}</span>
</Link>
)}
</ProfileLayout>
)
// const Translated = translate('AcccountViewer')(Presenter);
const mapDispatchToProps = (dispatch, props) => {
goToClub: bind(goToClub, dispatch)
}
const Provided = connect(mapDispatchToProps)(Presenter);
// Pure rendering-oriented component prepared for further enhancement
export const ProvidedStudentProfile = Provided;
const mapStateToProps = (state, props) => {
let student = getStudentByProfileId(state, props)
return { ...student }
}
const Connected = connect(mapStateToProps)(Provided);
export default Connected;
// ./app/components/Profile/TeacherProfile.js
import ProfileLayout from './_ProfileLayout';
import { getTeacherByProfileId } from '../selectors';
const Presenter = ({subjects_taught, t}) => (
<ProfileLayout>
{subjects_taught && subjects_taught.map((subject) =>
<span>{t('TEACH_A_SUBJECT', subject)}</span>
)}
</ProfileLayout>
)
// const Translated = translate('AcccountViewer')(Presenter);
// Pure rendering-oriented component prepared for further enhancement
export const ProvidedTeacherProfile = Presenter;
const mapStateToProps = (state, props) => {
let teacher = getTeacherByProfileId(state, props)
return { ...teacher }
}
const Connected = connect(mapStateToProps)(Presenter);
export default Connected;
// ./app/components/Profile/AutodetectedProfile.js
import { ProvidedTeacherProfile } from './TeacherProfile';
import { ProvidedStudentProfile } from './StudentProfile';
import { getMyProfile } from './selectors';
const Presenter = ({job_title, ...props}) => {
switch (job_title) {
case 'teacher';
return <ProvidedTeacherProfile {...props}/>;
case 'student':
return <ProvidedStudentProfile {...props}/>;
default:
return <div>{t('UNKNOWN_JOB_TITLE')}</div>
}
}
// const Translated = translate('AcccountViewer')(Presenter);
const mapStateToProps = (state, props) => {
let me = getMyProfile(state); // { job_title, ...student_or_teacher }
return { ...me }
}
const Connected = connect(mapStateToProps)(Presenter);
export default Connected;
// ./app/components/Profile/index.js
export TeacherProfile from './TeacherProfile';
export StudentProfile from './StudentProfile';
export MyProfile from './AutodetectedProfile';
// ./app/routes/index.js
import { StudentProfile, TeacherProfile, MyProfile } from '../components/Profile';
const RootRouter = () => (
<Router>
<Route path='/me' component={MyProfile}/>
<Route path='/teacher/:profile_id' component={TeacherProfile}/>
<Route path='/student/:profile_id' component={StudentProfile}/>
</Router>
)
Up to this point, we see some business logic behind is shared, like const Translated = translate('AcccountViewer')(Presenter);
, and no change is observed across all components
Secondly, since profile-id
_is used instead of _teacher-id
or student-id
, we probably consider same selector is to be utilised in place
