Let's start with mongoose !
🎯 Learning Objectives
This repository is a **hands-on tutorial** designed to teach you the fundamentals of Mongoose, the popular MongoDB object modeling library for Node.js. Through practical examples, you'll learn how to:
- 📦 Connect to MongoDB databases
- 📝 Create documents (INSERT operations)
- 🔍 Read documents with various query methods (SELECT operations)
- 🎨 Use schemas to structure your data
- 🔧 Work with ES Modules in a modern Node.js environment
many to one !
git 🛩️
This repository is designed to teach you about two different ways to implement many-to-one relationships in MongoDB using Mongoose. We'll use a classic example: Authors and Books.

Validation avec mongoose
Contrairement à mongodb qui ne permet pas de valider un schéma mongoose propose de nombreuses option de validation
lire : 🚀La validation Mongoose
import CVS
➤ Follow the Database Tools Installation Guide to install mongoimport.
😈 Run mongoimport from the system command line, not the mongo shell.
Example
🪛Lancez un terminal et ouvrir VisualStudio
>code .
🪛Créez un fichier File1.csv
name,num,email
you,20240001,you@univ-evry.fr
me,20240002,me@univ-evry.fr
🪛Dans le terminal exécutez la commande
C:\Users\DD>mongoimport --type csv --headerline --db MyFirstDatabase --collection students --file File1.csv
🚀Verification
🪛Avec mongosh
> db.students.find()
[
{
_id: ObjectId("65469262c769f35c5f4be3fe"),
name: 'you',
num: 20240001,
email: 'you@univ-evry.fr'
},
{
_id: ObjectId("65469262c769f35c5f4be3ff"),
name: 'me',
num: 20240002,
email: 'me@univ-evry.fr'
}

localhost versus 127.0.0.1
Il existe un fichier de config pour mongodb
D'après la note :
https://www.mongodb.com/docs/manual/reference/configuration-options/#mongodb-setting-net.bindIp
 |
Vous devez lancer : $ mongod --ipv6
Vous pourrez ainsi vous connecter avec l'écriture localhost
mongoose.connect('mongodb://localhost:27017/my_courses', { useUnifiedTopology: true, useNewUrlParser: true });
// mongoose.connect('mongodb://127.0.0.1:27017/my_courses', { useUnifiedTopology: true, useNewUrlParser: true });
