# Cosmos DB Support for VS Code (Preview)
[![Build Status](https://travis-ci.org/Microsoft/vscode-cosmosdb.svg?branch=master)](https://travis-ci.org/Microsoft/vscode-cosmosdb) [![Release Status](https://img.shields.io/github/tag/Microsoft/vscode-cosmosdb.svg?label=prerelease&colorB=0E7FC0)](https://github.com/Microsoft/vscode-cosmosdb/releases)

# Prerequisites

- Some less-common commands in the Mongo [scrapbook](#mongo-scrapbooks) and use of the Mongo shell require installing [Mongo DB and Mongo shell](https://docs.mongodb.com/manual/installation/).

# Features

## Cosmos DB Explorer

- Create a Cosmos DB account by clicking the `+` button in the title
- View Azure Cosmos DB accounts and open directly in the portal
- View/Create/Delete databases, collections, graphs, and documents
- Click on a document to open in the editor
- Click on a graph to visualize data
- Query graph using [Gremlin](https://docs.microsoft.com/azure/cosmos-db/gremlin-support)
- Edit a document and persist changes to the cloud
- Attach a Mongo server by clicking the plug icon in the title

*Support for Table accounts in CosmosDB is coming soon!

## Mongo "Scrapbooks" (Run Mongo Commands with Rich Intellisense)

- View your MongoDB database account by [signing in to Azure](#managing-azure-subscriptions) or attaching with a connection string
- Optionally configure the user setting `mongo.shell.path` to your mongo shell executable path (many of the common commands have built-in support and do not require the Mongo shell to be installed - see [Prerequisites](#prerequisites))
- Right-click on a database and select "Connect"
- Click on "New Mongo Scrapbook" in the tree title bar
- Enter your commands and/or comments, eg: `db.<collectionName>.find()`
- IntelliSense (auto-completions) will be provided
- Place the cursor inside the command to execute and press `CMD+"` (Mac) or `CTRL+"` (Windows and Linux) to see the results
- Save and re-use later

## Use [Gremlin](https://docs.microsoft.com/azure/cosmos-db/gremlin-support) to query graphs

![Query Graphs](resources/Graph.gif)

- <a name="graphSettings"></a>Configure the user setting `cosmosDB.graph.viewSettings` to customize which properties to display and which colors to use based on vertex label.
```javascript
    "cosmosDB.graph.viewSettings": [
        {
            "vertexSettings": [
                {
                    // Default settings for all vertices
                    "displayProperty": [
                        // Display name property if exists, otherwise firstName if it exists, otherwise ID
                        "name",
                        "firstName"
                    ],
                    // Auto-choose color by label
                    "color": "auto",
                    // Show label after display property
                    "showLabel": true
                },
                {
                    // These setting apply to vertices with the label 'person'
                    "appliesToLabel": "person",
                    "color": "blue"
                }
            ]
        }
    ]
```

## Create a Cosmos DB Account

## Attach to the Cosmos DB Emulator

* Install and run the [Cosmos DB Emulator](https://docs.microsoft.com/azure/cosmos-db/local-emulator) on your local machine
* Right click 'Attached Database Accounts' and select 'Attach Emulator'

## Managing Azure Subscriptions

If you are not signed in to Azure, you will see a "Sign in to Azure..." link. Alternatively, you can select "View->Command Palette" in the VS Code menu, and search for "Azure: Sign In".

![Sign in to Azure](resources/SignIn.gif)

If you don't have an Azure Account, you can sign up for one today for free and receive $200 in credits by selecting "Create a Free Azure Account..." or selecting "View->Command Palette" and searching for "Azure: Create an Account".

You may sign out of Azure by selecting "View->Command Palette" and searching for "Azure: Sign Out".

To select which subscriptions show up in the extension's explorer, click on the "Select Subscriptions..." button on any subscription node (indicated by a "filter" icon when you hover over it), or select "View->Command Palette" and search for "Azure: Select Subscriptions". Note that this selection affects all VS Code extensions that support the [Azure Account and Sign-In](https://github.com/Microsoft/vscode-azure-account) extension.

## Known Issues

- Azure no longer supports gremlin queries on pre-GA graph accounts. If you see the error "Could not find a valid gremlin endpoint for *graph*", then choose "Open Portal" on the graph node and check the "Gremlin Endpoint" in the Overview tab. If it does not take the form of '...[graph-name].***gremlin***.cosmosdb.azure.com...', then you will need to create a new graph account using the Azure portal or the current version of the extension.
- Graphs are not currently supported with the emulator
