# Mdbc

MongoDB Cmdlets for PowerShell Core 7.4

The PowerShell module based on the official [MongoDB C# driver](https://github.com/mongodb/mongo-csharp-driver)

## Quick start

**Step 1:** Get and install [Mdbc](https://www.powershellgallery.com/packages/Mdbc) from the PSGallery:

```powershell
Install-Module Mdbc
```

**Step 2:** Import the module:

```powershell
Import-Module Mdbc
```

**Step 3:** See help and available commands:

```powershell
help about_Mdbc
help Connect-Mdbc
Get-Command -Module Mdbc
```

**Step 4:** Make sure mongod is running and try some commands:

```powershell
# Load the module
Import-Module Mdbc

# Connect the new collection test.test
Connect-Mdbc . test test -NewCollection

# Add two documents
@{_id = 1; value = 42}, @{_id = 2; value = 3.14} | Add-MdbcData

# Get documents as PS objects
Get-MdbcData -As PS | Format-Table

# Get the document by _id
Get-MdbcData @{_id = 1}

# Update the document, set 'value' to 100
Update-MdbcData @{_id = 1} @{'$set' = @{value = 100}}

# Get the document again, 'value' is 100
$doc = Get-MdbcData @{_id = 1}

# Remove the document
$doc | Remove-MdbcData

# Count documents, 1
Get-MdbcData -Count
```

Read cmdlet help topics and take a look at examples for some basic use cases.

Use [Mdbc.ArgumentCompleters.ps1] for database and collection name completion and property completion.
You may install this script from the PSGallery as [Mdbc.ArgumentCompleters](https://www.powershellgallery.com/packages/Mdbc.ArgumentCompleters):

```powershell
Install-Script Mdbc.ArgumentCompleters
```

Use [Update-MongoFiles.ps1], either for making some test data or for tracking file changes in practice.
