Develop Azure Functions by using Visual Studio Code

The Azure Functions extension for Visual Studio Code lets you locally develop functions and deploy them to Azure. If this experience is your first with Azure Functions, you can learn more at An introduction to Azure Functions.

The Azure Functions extension provides these benefits:

  • Edit, build, and run functions on your local development computer.
  • Publish your Azure Functions project directly to Azure.
  • Write your functions in various languages while taking advantage of the benefits of Visual Studio Code.

Important

Don't mix local development and portal development for a single function app. When you publish from a local project to a function app, the deployment process overwrites any functions that you developed in the portal.

Prerequisites

You also need these prerequisites to run and debug your functions locally. They aren't required to just create or publish projects to Azure Functions.

::: zone-end

Create an Azure Functions project

The Functions extension lets you create the required function app project at the same time you create your first function. Use these steps to create an HTTP-triggered function in a new project. An HTTP trigger is the simplest function trigger template to demonstrate.

  1. In the Activity bar, select the Azure icon. In the Workspace (Local) area, open the + list, and select Create Function.

    :::image type="content" source="./media/functions-create-first-function-vs-code/create-new-project.png" alt-text="Screenshot of create a new project window.":::

  2. When prompted, select Create new project. Select the directory location for your project workspace, and then choose Select.

    You can either create a new folder or choose an empty folder for the project workspace, but don't choose a project folder that's already part of a workspace.

  3. When prompted, Select a language for your project. If necessary, choose a specific language version.

  4. Select the HTTP trigger function template, or you can select Skip for now to create a project without a function. You can always add a function to your project later.

    :::image type="content" source="./media/functions-develop-vs-code/select-http-trigger.png" alt-text="Screenshot for selecting HTTP trigger.":::

    [!TIP] You can view additional templates by selecting the Change template filter option and setting the value to Core or All.

  5. For the function name, enter HttpExample, select Enter, and then select Function authorization.

    This authorization level requires that you provide a function key when you call the function endpoint.

    :::image type="content" source="./media/functions-develop-vs-code/create-function-auth.png" alt-text="Screenshot for creating function authorization.":::

  6. From the dropdown list, select Add to workspace.

    :::image type="content" source="./media/functions-develop-vs-code/add-to-workplace.png" alt-text=" Screenshot for selectIng Add to workplace.":::

  7. In the Do you trust the authors of the files in this folder? window, select Yes.

    :::image type="content" source="./media/functions-develop-vs-code/select-author-file.png" alt-text="Screenshot to confirm trust in authors of the files.":::

Visual Studio Code creates a function in your chosen language and in the template for an HTTP-triggered function.

Generated project files

The project template creates a project in your chosen language and installs the required dependencies. For any language, the new project has these files:

  • host.json: Lets you configure the Functions host. These settings apply when you're running functions locally and when you're running them in Azure. For more information, see host.json reference.

  • local.settings.json: Maintains settings used when you're locally running functions. These settings are used only when you're running functions locally. For more information, see Local settings file.

    [!IMPORTANT] Because the local.settings.json file can contain secrets, make sure to exclude the file from your project source control.

Depending on your language, these other files are created:

::: zone pivot="programming-language-csharp"
An HttpExample.cs class library file, the contents of which vary depending on whether your project runs in an isolated worker process or in-process with the Functions host. ::: zone-end
::: zone pivot="programming-language-java"

  • A pom.xml file in the root folder that defines the project and deployment parameters, including project dependencies and the Java version. The pom.xml also contains information about the Azure resources that are created during a deployment.

  • A Functions.java file in your src path that implements the function. ::: zone-end
    ::: zone pivot="programming-language-javascript,programming-language-typescript" Files generated depend on the chosen Node.js programming model for Functions:

v4

  • A package.json file in the root folder.

  • A named .js file in the src\functions folder, which contains both the function definition and your function code.

v3

::: zone-end
::: zone pivot="programming-language-powershell"
An HttpExample folder that contains:

::: zone-end
::: zone pivot="programming-language-python"
Files generated depend on the chosen Python programming model for Functions:

v2

  • A project-level requirements.txt file that lists packages required by Functions.

  • A function_app.py file that contains both the function definition and code.

v1

  • A project-level requirements.txt file that lists packages required by Functions.

  • An HttpExample folder that contains:

::: zone-end

At this point, you're able to run your HTTP trigger function locally.

Add a function to your project

You can add a new function to an existing project based on one of the predefined Functions trigger templates. To add a new function trigger, select F1 to open the command palette, and then find and run the command Azure Functions: Create Function. Follow the prompts to choose your trigger type and define the required attributes of the trigger. If your trigger requires an access key or connection string to connect to a service, get that item ready before you create the function trigger.

::: zone pivot="programming-language-csharp" This action adds a new C# class library (.cs) file to your project. ::: zone-end ::: zone pivot="programming-language-java" This action adds a new Java (.java) file to your project. ::: zone-end ::: zone pivot="programming-language-javascript,programming-language-typescript" This action's results depend on the Node.js model version.

v4

  • A package.json file in the root folder.

  • A named .js file in the src\functions folder, which contains both the function definition and your function code.

v3

Visual Studio Code creates a new folder in the project. The folder contains a new function.json file and the new JavaScript code file.

::: zone-end ::: zone pivot="programming-language-powershell" This action creates a new folder in the project. The folder contains a new function.json file and the new PowerShell code file. ::: zone-end ::: zone pivot="programming-language-python" This action's results depends on the Python model version.

v2

Visual Studio Code adds new function code either to the function_app.py file (default behavior) or to another Python file that you selected.

v1

Visual Studio Code creates a new folder in the project. The folder contains a new function.json file and the new Python code file.

::: zone-end

Connect to services

You can connect your function to other Azure services by adding input and output bindings. Bindings connect your function to other services without you having to write the connection code.

::: zone pivot="programming-language-csharp" For example, the way that you define an output binding that writes data to a storage queue depends on your process model:

Isolated process

  1. If necessary, add a reference to the package that supports your binding extension.

  2. Update the function method to add an attribute that defines the binding parameter, like QueueOutput for a queue output binding. You can use a MultiResponse object to return multiple messages or multiple output streams.

In-process

  1. If necessary, add a reference to the package that supports your binding extension.

  2. Update the function method to add an attribute that defines the binding parameter, such as Queue for a Queue binding. You can use an ICollector<T> type to represent a collection of messages.

::: zone-end
::: zone pivot="programming-language-java"
For example, to add an output binding that writes data to a storage queue you update the function method to add a binding parameter defined by using the QueueOutput annotation. The OutputBinding<T> object represents the messages that are written to an output binding when the function completes. ::: zone-end
::: zone pivot="programming-language-javascript" For example, the way that you define the output binding that writes data to a storage queue depends on your Node.js model version:

v4

Using the Node.js v4 model, you must manually add a return: option in the function definition using the storageQueue function on the output object, which defines the storage queue to write the return output. The output is written when the function completes.

v3

[!INCLUDE functions-add-output-binding-vs-code]

::: zone-end ::: zone pivot="programming-language-powershell" [!INCLUDE functions-add-output-binding-vs-code] ::: zone-end

::: zone pivot="programming-language-python" For example, the way you define the output binding that writes data to a storage queue depends on your Python model version:

v2

The @queue_output decorator on the function is used to define a named binding parameter for the output to the storage queue, where func.Out defines what output is written.

Create Azure resources

Before you can publish your Functions project to Azure, you must have a function app and related resources in your Azure subscription to run your code. The function app provides an execution context for your functions. When you publish from Visual Studio Code to a function app in Azure, the project is packaged and deployed to the selected function app in your Azure subscription.

When you create a function app in Azure, you can choose either a quick function app create path using defaults or an advanced path. This way, you have more control over creating the remote resources.

Quick function app create

[!INCLUDE functions-create-azure-resources-vs-code]

Publish a project to a new function app in Azure by using advanced options

The following steps publish your project to a new function app created with advanced create options:

  1. In the command palette, enter Azure Functions: Create function app in Azure...(Advanced).

  2. If you're not signed in, you're prompted to Sign in to Azure. You can also Create a free Azure account. After signing in from the browser, go back to Visual Studio Code.

  3. Following the prompts, provide this information:

    Prompt Selection
    Enter a globally unique name for the new function app. Type a globally unique name that identifies your new function app and then select Enter. Valid characters for a function app name are a-z, 0-9, and -.
    Select a runtime stack. Choose the language version that you're locally running.
    Select an OS. Choose either Linux or Windows. Python apps must run on Linux.
    Select a resource group for new resources. Choose Create new resource group, and enter a resource group name such as myResourceGroup. You can also select an existing resource group.
    Select a location for new resources. Select a location in a region near you or near other services that your functions access.
    Select a hosting plan. Choose Consumption for serverless Consumption plan hosting, where you're charged only when your functions run.
    Select a storage account. Choose Create new storage account, and at the prompt, enter a globally unique name for the new storage account used by your function app. Storage account names must be between 3 and 24 characters long and can contain only numbers and lowercase letters. You can also select an existing account.
    Select an Application Insights resource for your app. Choose Create new Application Insights resource, and at the prompt, enter a name for the instance used to store runtime data from your functions.

    A notification appears after your function app is created, and the deployment package is applied. To view the creation and deployment results, including the Azure resources that you created, select View Output in this notification.

Get the URL of an HTTP triggered function in Azure

To call an HTTP-triggered function from a client, you need the function's URL, which is available after deployment to your function app. This URL includes any required function keys. You can use the extension to get these URLs for your deployed functions. If you just want to run the remote function in Azure, use the Execute function now functionality of the extension.

  1. Select F1 to open the command palette, and then find and run the command Azure Functions: Copy Function URL.

  2. Follow the prompts to select your function app in Azure and then the specific HTTP trigger that you want to invoke.

The function URL is copied to the clipboard, along with any required keys passed by the code query parameter. Use an HTTP tool to submit POST requests, or a browser to submit GET requests to the remote function.

When the extension gets the URL of a function in Azure, the extension uses your Azure account to automatically retrieve the keys needed to start the function. Learn more about function access keys. Starting non-HTTP triggered functions requires using the admin key.

Deploy project files

We recommend setting up continuous deployment so that your function app in Azure is updated when you update source files in the connected source location. You can also deploy your project files from Visual Studio Code. When you publish from Visual Studio Code, you can take advantage of the Zip deploy technology.

[!INCLUDE functions-deploy-project-vs-code]

Run functions

The Azure Functions extension lets you run individual functions. You can run functions either in your project on your local development computer or in your Azure subscription.

For HTTP trigger functions, the extension calls the HTTP endpoint. For other kinds of triggers, the extension calls administrator APIs to start the function. The message body of the request sent to the function depends on the trigger type. When a trigger requires test data, you're prompted to enter data in a specific JSON format.

Run functions in Azure

To execute a function in Azure from Visual Studio Code, follow these steps:

  1. In the command palette, enter Azure Functions: Execute function now, and select your Azure subscription.

  2. From the list, choose your function app in Azure. If you don't see your function app, make sure you're signed in to the correct subscription.

  3. From the list, choose the function that you want to run. In Enter request body, type the message body of the request, and press Enter to send this request message to your function.

    The default text in Enter request body indicates the body's format. If your function app has no functions, a notification error is shown with this error.

    When the function executes in Azure and returns a response, Visual Studio Code shows a notification.

You can also run your function from the Azure: Functions area by opening the shortcut menu for the function that you want to run from your function app in your Azure subscription, and then selecting Execute Function Now....

When you run your functions in Azure from Visual Studio Code, the extension uses your Azure account to automatically retrieve the keys needed to start the function. Learn more about function access keys. Starting non-HTTP triggered functions requires using the admin key.

Run functions locally

The local runtime is the same runtime that hosts your function app in Azure. Local settings are read from the local.settings.json file. To run your Functions project locally, you must meet more requirements.

Configure the project to run locally

The Functions runtime uses an Azure Storage account internally for all trigger types other than HTTP and webhooks. So you need to set the Values.AzureWebJobsStorage key to a valid Azure Storage account connection string.

This section uses the Azure Storage extension for Visual Studio Code with Azure Storage Explorer to connect to and retrieve the storage connection string.

To set the storage account connection string:

  1. In Visual Studio, open Cloud Explorer, expand Storage Account > Your Storage Account, and then select Properties and copy the Primary Connection String value.

  2. In your project, open the local.settings.json file and set the value of the AzureWebJobsStorage key to the connection string you copied.

  3. Repeat the previous step to add unique keys to the Values array for any other connections required by your functions.

For more information, see Local settings file.

Debug functions locally

To debug your functions, select F5. If Core Tools isn't available, you're prompted to install it. When Core Tools is installed and running, output is shown in the Terminal. This step is the same as running the func start Core Tools command from the Terminal, but with extra build tasks and an attached debugger.

When the project is running, you can use the Execute Function Now... feature of the extension to trigger your functions as you would when the project is deployed to Azure. With the project running in debug mode, breakpoints are hit in Visual Studio Code as you would expect.

  1. In the command palette, enter Azure Functions: Execute function now and choose Local project.

  2. Choose the function you want to run in your project and type the message body of the request in Enter request body. Press Enter to send this request message to your function. The default text in Enter request body should indicate the format of the body. If your function app has no functions, a notification error is shown with this error.

  3. When the function runs locally and after the response is received, a notification is raised in Visual Studio Code. Information about the function execution is shown in Terminal panel.

Keys aren't required when running locally, which applies to both function keys and admin-level keys.

[!INCLUDE functions-local-settings-file]

By default, these settings aren't migrated automatically when the project is published to Azure. After publishing finishes, you're given the option of publishing settings from local.settings.json to your function app in Azure. To learn more, see Publish application settings.

Values in ConnectionStrings are never published.

::: zone pivot="programming-language-csharp"

Isolated process

The function application settings values can also be read in your code as environment variables. For more information, see Environment variables.

In-process

The function application settings values can also be read in your code as environment variables as with any ASP.NET Core app.

::: zone-end ::: zone pivot="programming-language-java"

  • The function app settings values can also be read in your code as environment variables. For more information, see Environment variables. ::: zone-end ::: zone pivot="programming-language-javascript,programming-language-typescript"
  • The function app settings values can also be read in your code as environment variables. For more information, see Environment variables. ::: zone-end ::: zone pivot="programming-language-powershell"
  • The function app settings values can also be read in your code as environment variables. For more information, see Environment variables. ::: zone-end ::: zone pivot="programming-language-python"
  • The function app settings values can also be read in your code as environment variables. For more information, see Environment variables. ::: zone-end

Application settings in Azure

The settings in the local.settings.json file in your project should be the same as the application settings in the function app in Azure. Any settings you add to local.settings.json you must also add to the function app in Azure. These settings aren't uploaded automatically when you publish the project. Likewise, any settings that you create in your function app in the portal must be downloaded to your local project.

Publish application settings

The easiest way to publish the required settings to your function app in Azure is to use the Upload settings link that appears after you publish your project:

:::image type="content" source="./media/functions-develop-vs-code/upload-app-settings.png" alt-text="Screenshot to upload application settings.":::

You can also publish settings by using the Azure Functions: Upload Local Setting command in the command palette. You can add individual settings to application settings in Azure by using the Azure Functions: Add New Setting command.

Tip

Be sure to save your local.settings.json file before you publish it.

If the local file is encrypted, it's decrypted, published, and encrypted again. If there are settings that have conflicting values in the two locations, you're prompted to choose how to proceed.

View existing app settings in the Azure: Functions area by expanding your subscription, your function app, and Application Settings.

:::image type="content" source="./media/functions-develop-vs-code/view-app-settings.png" alt-text=" Screenshot for viewing function app settings in Visual Studio Code.":::

Download settings from Azure

If you've created application settings in Azure, you can download them into your local.settings.json file by using the Azure Functions: Download Remote Settings command.

As with uploading, if the local file is encrypted, it's decrypted, updated, and encrypted again. If there are settings that have conflicting values in the two locations, you're prompted to choose how to proceed.

Install binding extensions

Except for HTTP and timer triggers, bindings are implemented in extension packages.

::: zone pivot="programming-language-csharp"
You must explicitly install the extension packages for the triggers and bindings that need them. The specific package you install depends on your project's process model.

Isolated process

Run the dotnet add package command in the Terminal window to install the extension packages that you need in your project. This template demonstrates how you add a binding for an isolated-process class library:

dotnet add package Microsoft.Azure.Functions.Worker.Extensions.<BINDING_TYPE_NAME> --version <TARGET_VERSION>

In-process

Run the dotnet add package command in the Terminal window to install the extension packages that you need in your project. This template demonstrates how you add a binding for an in-process class library:

dotnet add package Microsoft.Azure.WebJobs.Extensions.<BINDING_TYPE_NAME> --version <TARGET_VERSION>

Replace <BINDING_TYPE_NAME> with the name of the package that contains the binding you need. You can find the desired binding reference article in the list of supported bindings.

Replace <TARGET_VERSION> in the example with a specific version of the package, such as 3.0.0-beta5. Valid versions are listed on the individual package pages at NuGet.org. The major versions that correspond to the current Functions runtime are specified in the reference article for the binding.

C# script uses extension bundles.

::: zone-end
::: zone pivot="programming-language-java,programming-language-javascript,programming-language-powershell,programming-language-python,programming-language-typescript" [!INCLUDE functions-extension-bundles]

If for some reason you can't use an extension bundle to install binding extensions for your project, see Explicitly install extensions. ::: zone-end

Monitoring functions

When you run functions locally, log data is streamed to the Terminal console. You can also get log data when your Functions project is running in a function app in Azure. You can connect to streaming logs in Azure to see near-real-time log data. You should enable Application Insights for a more complete understanding of how your function app is behaving.

::: zone pivot="programming-language-java,programming-language-javascript,programming-language-powershell,programming-language-csharp,programming-language-typescript"

Streaming logs

When you're developing an application, it's often useful to see logging information in near-real time. You can view a stream of log files being generated by your functions. Turn on logs from the command pallet with the Azure Functions: Start streaming logs command. This output is an example of streaming logs for a request to an HTTP-triggered function:

:::image type="content" source="media/functions-develop-vs-code/streaming-logs-vscode-console.png" alt-text="Screenshot for streaming logs output for H T T P trigger.":::

To learn more, see Streaming logs. ::: zone-end

Application Insights

You should monitor the execution of your functions by integrating your function app with Application Insights. When you create a function app in the Azure portal, this integration occurs by default. When you create your function app during Visual Studio publishing, you need to integrate Application Insights yourself. To learn how, see Enable Application Insights integration.

To learn more about monitoring using Application Insights, see Monitor Azure Functions.

::: zone pivot="programming-language-csharp"

C# script projects

By default, all C# projects are created as C# compiled class library projects. If you prefer to work with C# script projects instead, you must select C# script as the default language in the Azure Functions extension settings:

  1. Select File > Preferences > Settings.

  2. Go to User Settings > Extensions > Azure Functions.

  3. Select C#Script from Azure Function: Project Language.

After you complete these steps, calls made to the underlying Core Tools include the --csx option, which generates and publishes C# script (.csx) project files. When you have this default language specified, all projects that you create default to C# script projects. You're not prompted to choose a project language when a default is set. To create projects in other languages, you must change this setting or remove it from the user settings.json file. After you remove this setting, you're again prompted to choose your language when you create a project. ::: zone-end

Command palette reference

The Azure Functions extension provides a useful graphical interface in the area for interacting with your function apps in Azure. The same functionality is also available as commands in the command palette (F1). These Azure Functions commands are available:

Azure Functions command Description
Add New Settings Creates a new application setting in Azure. To learn more, see Publish application settings. You might also need to download this setting to your local settings.
Configure Deployment Source Connects your function app in Azure to a local Git repository. To learn more, see Continuous deployment for Azure Functions.
Connect to GitHub Repository Connects your function app to a GitHub repository.
Copy Function URL Gets the remote URL of an HTTP-triggered function that's running in Azure. To learn more, see Get the URL of the deployed function.
Create function app in Azure Creates a new function app in your subscription in Azure. To learn more, see the section on how to publish to a new function app in Azure.
Decrypt Settings Decrypts local settings that have been encrypted by Azure Functions: Encrypt Settings.
Delete Function App Removes a function app from your subscription in Azure. When there are no other apps in the App Service plan, you're given the option to delete that too. Other resources, like storage accounts and resource groups, aren't deleted. To remove all resources, you should instead delete the resource group. Your local project isn't affected.
Delete Function Removes an existing function from a function app in Azure. Because this deletion doesn't affect your local project, instead consider removing the function locally and then republishing your project.
Delete Proxy Removes an Azure Functions proxy from your function app in Azure. To learn more about proxies, see Work with Azure Functions Proxies.
Delete Setting Deletes a function app setting in Azure. This deletion doesn't affect settings in your local.settings.json file.
Disconnect from Repo Removes the continuous deployment connection between a function app in Azure and a source control repository.
Download Remote Settings Downloads settings from the chosen function app in Azure into your local.settings.json file. If the local file is encrypted, it's decrypted, updated, and encrypted again. If there are settings that have conflicting values in the two locations, you're prompted to choose how to proceed. Be sure to save changes to your local.settings.json file before you run this command.
Edit settings Changes the value of an existing function app setting in Azure. This command doesn't affect settings in your local.settings.json file.
Encrypt settings Encrypts individual items in the Values array in the local settings. In this file, IsEncrypted is also set to true, which specifies that the local runtime decrypt settings before using them. Encrypt local settings to reduce the risk of leaking valuable information. In Azure, application settings are always stored encrypted.
Execute Function Now Manually starts a function using admin APIs. This command is used for testing, both locally during debugging and against functions running in Azure. When a function in Azure starts, the extension first automatically obtains an admin key, which it uses to call the remote admin APIs that start functions in Azure. The body of the message sent to the API depends on the type of trigger. Timer triggers don't require you to pass any data.
Initialize Project for Use with VS Code Adds the required Visual Studio Code project files to an existing Functions project. Use this command to work with a project that you created by using Core Tools.
Install or Update Azure Functions Core Tools Installs or updates Azure Functions Core Tools, which is used to run functions locally.
Redeploy Lets you redeploy project files from a connected Git repository to a specific deployment in Azure. To republish local updates from Visual Studio Code, republish your project.
Rename Settings Changes the key name of an existing function app setting in Azure. This command doesn't affect settings in your local.settings.json file. After you rename settings in Azure, you should download those changes to the local project.
Restart Restarts the function app in Azure. Deploying updates also restarts the function app.
Set AzureWebJobsStorage Sets the value of the AzureWebJobsStorage application setting. This setting is required by Azure Functions. It's set when a function app is created in Azure.
Start Starts a stopped function app in Azure.
Start Streaming Logs Starts the streaming logs for the function app in Azure. Use streaming logs during remote troubleshooting in Azure if you need to see logging information in near-real time. To learn more, see Streaming logs.
Stop Stops a function app that's running in Azure.
Stop Streaming Logs Stops the streaming logs for the function app in Azure.
Toggle as Slot Setting When enabled, ensures that an application setting persists for a given deployment slot.
Uninstall Azure Functions Core Tools Removes Azure Functions Core Tools, which is required by the extension.
Upload Local Settings Uploads settings from your local.settings.json file to the chosen function app in Azure. If the local file is encrypted, it's decrypted, uploaded, and encrypted again. If there are settings that have conflicting values in the two locations, you're prompted to choose how to proceed. Be sure to save changes to your local.settings.json file before you run this command.
View Commit in GitHub Shows you the latest commit in a specific deployment when your function app is connected to a repository.
View Deployment Logs Shows you the logs for a specific deployment to the function app in Azure.
