9. Interim Conclusion

The twenty examples have introduced the concepts we need to write the [RdvMedecins] client:

Concept	Where it will be used in the case study
components, props, [v-model], slots	the navigation bar, form fields, windows
[ref], [reactive], [computed], [watch]	all pages; the calendar that follows its URL
composables	the confirmation window, formatting, and form errors
the router and its guards	the pages, the permissions for each role, the session to be restored after F5
Pinia	the logged-in user, success and error messages
[vue-i18n]	French and English, and the translation of server errors
fetch, httpOnly cookie, proxy	the connection and all communication with the server
the API access layer	a [rdvmedecins.api.ts] file, one function per route

The client will be the exact equivalent of the HTML application from the [NestJS] course, page by page. The difference lies elsewhere: the server no longer generates any pages; it responds in JSON, and everything related to display (pages, language, date formatting, messages) has been moved to the browser.
