CONFLICT srcs/requirements/nestjs/api_back/src/friendship/friendship.service.ts


### Pour lancer le docker :

- Il faut un fichier .env qu'on ne doit pas push, donc je ne le push pas.
- Pour l'instant, on doit donc le faire à la main (je verrai par la suite comment faire mieux).
- Dans le .env il y a juste à mettre (sans les guillemets) "NODE_ENV=development" ou "NODE_ENV=production".
- Il faut le placer au même endroit que docker-compose.yml
- Dans le makefile il y a un sedf pour changer l'un ou l'autre.

- also add an alias for transcendance in /etc/hosts



### TODO List : Utilisateur édition.

- [x] Utilisateur : faire la base pour un utilisateur
- [x] Utilisateur : faire le système de requêtes amis
- [x] Utilisateur : mettre en place le système de session (voire de statut ?)
- [x] Utilisateur : mettre en place le système d'avatar
- [x] Utilisateur : mettre en place la double authentification
- [x] Utilisateur : mettre en place le système d'Oauth
- [x] Utilisateur : mettre en place la hashage de mot de passe (avec Oauth)
- [x] Utilisateur : mettre en place le système de statut
- [x] Utilisateur : mettre en place le système de stats
- [x] Utilisateur : mettre en place l'historique des matches

### TODO List : Docker édition.

- [ ] Docker : trouver un moyen simple de générer un .env. Peut-être renouveller les clé à chaque lancement.
