A MongoDB survival pill

When you think about Web development, there are tons of technologies, tools, & blah blah things to keep in mind. The chances of getting overwhelmed becomes 🔝.

Same goes with Databases. Today, we are talking about the non relational database.

MongoDB 😅

A quick guide for handling MongoDB database from our local machine through command prompt 💻

---

Let's get started

• Show All Databases 🔎

show dbs

• Show Current Database 👨‍💻

db

• Create Or Switch Database ⏭

use <database_name>

• Drop Database 🔥

db.dropDatabase()

• Create Collection 👨‍🔧 > "collection" is similar to "table" in the SQL .

We call "tables" as "collections" in MongoDB .

Here, 'posts' is the name of our collection.

db.createCollection('posts')

• Show Collections 🔎

show collections

Now, we have created a 'collection' called "posts" & then we will populate our collection with some data. To do that paste below schema into command prompt 👇

Insert Row

db.posts.insert({
  title: 'Post 1',
  body: 'Hello, this is post one',
  category: 'Sports',
  tags: ['young', 'stadium'],
  user: {
    name: 'Jayesh Tembhekar',
    status: 'author'
  },
  date: Date()
})

To speed up the insertion, we can insert multiple rows at a time like this...

• Insert Multiple Rows 🥇

db.posts.insertMany([
  {
    title: 'Post 2',
    body: 'Hello, this is post two',
    category: 'Technology',
    date: Date()
  },
  {
    title: 'Post 3',
    body: 'Hello, this is post three',
    category: 'Politics',
    date: Date()
  },
  {
    title: 'Post 4',
    body: 'Hello, this is post four',
    category: 'Entertainment',
    date: Date()
  }
])

to be continued...

Have a great day !
