In this article, you will learn about how to create and save a schema array of strings in Mongoose.
Mongoose is an ODM(Object Data Modeling) library for MongoDB and it lets you create a schema model and save documents in MongoDB. In the Mongoose schema model, you can create an array of strings. To create it is as simple as defining a single type in the mongoose schema. Let’s see the below code example where we have created a student schema and also use array of strings.
const mongoose = require('mongoose')
const studentSchema = new mongoose.Schema({
name : {
type : String
},
age : {
type : String
},
courses : [{
type: String
}]
})
const Student = mongoose.model('Student',studentSchema)
module.exports = StudentYou can see that we have created a schema array of strings in the course’s portion. Because a student may have multiple courses and this is how you can create a schema array of strings in Mongoose.
Let’s move on to the next part where you can save a schema document that has an array of strings. To do so follow the below code. Let me assume that, you have already known how to create a basic server and connection of MongoDB atlas and other basic stuff.
router.post('/student', async (req,res,next) =>{
let {name,age,courses} = req.body
try{
let student = new Student({
name,
age,
courses
})
let newStudent = await student.save()
res.status(200).json({
status: 'Success',
data : student
})
}catch(err){
console.log(err)
next(err)
}
})Here, we are just showing you how you can save a document that contains an array of strings, and you can see that it is not different from creating a document that does not contain an array of strings. Let’s create a student and see what happens. To create data we are using postman.
In postman, we have sent a post request in a specific route with the credentials along with the courses array. We have also set a 200 status code and let’s check the output in the postman:
You can see that it shows success status with the information that we have provided and also generated a unique ID for us. Now let’s check it into the MongoDB database in the below:
Here, the data has been saved successfully in the MongoDB database and the type of courses has shown as an Array. This is how you can create and save a schema array of strings in Mongoose.
