# How to Connect and Use Mongosh in VS Code via MongoDB Extension

## **MongoDB for VS Code**

You can use **MongoDB for VS Code** to connect to MongoDB and interact with it using **mongosh**. Here’s a step-by-step guide:

***

### **1. Install MongoDB Extension for VS Code**

1. **Open VS Code**.
2. Click on the **Extensions** tab (or press `Ctrl+Shift+X`).

* If you have a **local MongoDB server that provide daemon service**,  click localhost:27017  with  right mouse and select connect> 
* Get MongoDB Server service on (start service) and then  run mongod at command terminal. 

  ```arduino
  mongodb://localhost:27017

  2. Select your database and **click "Connect"**.
  3. Choose **"Connect using MongoDB Compass"** and copy the connection string.
  4. Paste the connection string in VS Code’s **MongoDB extension**.
  5. Replace `<password>` with your database password.

   ```sh
   mongosh
   ```

   This will connect to your **default MongoDB instance**. Select  Launch MongoDB Shell to open mongosh shell at the vscode terminal.
