Azure Functions Core Tools lets you develop and test your functions on your local computer from the command prompt or terminal. Your local functions can connect to live Azure services, and you can debug your functions on your local computer using the full Functions runtime. You can even deploy a function app to your Azure subscription.

Important

Do not mix local development with portal development in the same function app. When you create and publish functions from a local project, you should not try to maintain or modify project code in the portal.

Developing functions on your local computer and publishing them to Azure using Core Tools follows these basic steps:

Core Tools versions

There are three versions of Azure Functions Core Tools. The version you use depends on your local development environment, choice of language, and level of support required:

• Version 1.x: Supports version 1.x of the Azure Functions runtime. This version of the tools is only supported on Windows computers and is installed from an npm package.

• Version 3.x/2.x: Supports either version 3.x or 2.x of the Azure Functions runtime. These versions support Windows, macOS, and Linux and use platform-specific package managers or npm for installation.

Unless otherwise noted, the examples in this article are for version 3.x.

Install the Azure Functions Core Tools

Azure Functions Core Tools includes a version of the same runtime that powers Azure Functions runtime that you can run on your local development computer. It also provides commands to create functions, connect to Azure, and deploy function projects.

Important

You must have the Azure CLI installed locally to be able to publish to Azure from Azure Functions Core Tools.

Version 3.x and 2.x

Launching Python App On Mac Locally Download

Version 3.x/2.x of the tools uses the Azure Functions runtime that is built on .NET Core. This version is supported on all platforms .NET Core supports, including Windows, macOS, and Linux.

Important

You can bypass the requirement for installing the .NET Core SDK by using extension bundles.

The following steps use npm to install Core Tools on Windows. You can also use Chocolatey. For more information, see the Core Tools readme.

1. Install Node.js, which includes npm.

   • For version 3.x of the tools, only Node.js 10 and later versions are supported.
   • For version 2.x of the tools, only Node.js 8.5 and later versions are supported.

2. Install the Core Tools package:

   v3.x (recommended)

   v2.x

   It may take a few minutes for npm to download and install the Core Tools package.

3. If you don't plan to use extension bundles, install the .NET Core 3.x SDK for Windows.

The following steps use Homebrew to install the Core Tools on macOS.

Sometimes, there are situations in you will have to do the wrong thing to do something right. This doesn’t limit the accessibility as its simple user interface ensures that even a non-professional can use it. Gmail Password Keygen doesn’t require you to spend an hour on hacking but it completes the hack in a matter of a few minutes. Gmail hacking software for mac.

1. Install Homebrew, if it's not already installed.

2. Install the Core Tools package:

   v3.x (recommended)

   v2.x

3. If you don't plan to use extension bundles, install the .NET Core 3.x SDK for macOS.

The following steps use APT to install Core Tools on your Ubuntu/Debian Linux distribution. For other Linux distributions, see the Core Tools readme.

1. Install the Microsoft package repository GPG key, to validate package integrity:

2. Set up the APT source list before doing an APT update.

   Ubuntu

   Debian

3. Check the /etc/apt/sources.list.d/dotnetdev.list file for one of the appropriate Linux version strings listed below:

   Ubuntu 18.10	cosmic
   Ubuntu 18.04	bionic
   Ubuntu 17.04	zesty
   Ubuntu 16.04/Linux Mint 18	xenial

4. Start the APT source update:

5. Install the Core Tools package:

   v3.x (recommended)

   v2.x

6. If you don't plan to use extension bundles, install .NET Core 3.x SDK for Linux.

Create a local Functions project

A functions project directory contains the files host.json and local.settings.json, along with subfolders that contain the code for individual functions. This directory is the equivalent of a function app in Azure. To learn more about the Functions folder structure, see the Azure Functions developers guide.

Version 3.x/2.x requires you to select a default language for your project when it is initialized. In version 3.x/2.x, all functions added use default language templates. In version 1.x, you specify the language each time you create a function.

In the terminal window or from a command prompt, run the following command to create the project and local Git repository:

When you provide a project name, a new folder with that name is created and initialized. Otherwise, the current folder is initialized.
In version 3.x/2.x, when you run the command you must choose a runtime for your project.

Use the up/down arrow keys to choose a language, then press Enter. If you plan to develop JavaScript or TypeScript functions, choose node, and then select the language. TypeScript has some additional requirements.

The output looks like the following example for a JavaScript project:

func init supports the following options, which are version 3.x/2.x-only, unless otherwise noted:

Important

By default, version 2.x and later versions of the Core Tools create function app projects for the .NET runtime as C# class projects (.csproj). These C# projects, which can be used with Visual Studio or Visual Studio Code, are compiled during testing and when publishing to Azure. If you instead want to create and work with the same C# script (.csx) files created in version 1.x and in the portal, you must include the --csx parameter when you create and deploy functions.

Register extensions

With the exception of HTTP and timer triggers, Functions bindings in runtime version 2.x and higher are implemented as extension packages. In version 2.x and beyond of the Azure Functions runtime, you have to explicitly register the extensions for the binding types used in your functions. The exceptions to this are HTTP bindings and timer triggers, which do not require extensions.

You can choose to install binding extensions individually, or you can add an extension bundle reference to the host.json project file. Extension bundles removes the chance of having package compatibility issues when using multiple binding types. It is the recommended approach for registering binding extensions. Extension bundles also removes the requirement of installing the .NET Core 2.x SDK.

Extension bundles

The easiest way to install binding extensions is to enable extension bundles. When you enable bundles, a predefined set of extension packages is automatically installed.

To enable extension bundles, open the host.json file and update its contents to match the following code:

To learn more, see Register Azure Functions binding extensions. You should add extension bundles to the host.json before you add bindings to the function.json file.

Register individual extensions

Launching Python App On Mac Locally Computer

If you need to install extensions that aren't in a bundle, you can manually register individual extension packages for specific bindings.

Note

To manually register extensions by using func extensions install, you must have the .NET Core 2.x SDK installed.

After you have updated your function.json file to include all the bindings that your function needs, run the following command in the project folder.

The command reads the function.json file to see which packages you need, installs them, and rebuilds the extensions project. It adds any new bindings at the current version but does not update existing bindings. Use the --force option to update existing bindings to the latest version when installing new ones.

Local settings file

The local.settings.json file stores app settings, connection strings, and settings used by local development tools. Settings in the local.settings.json file are used only when you're running projects locally. The local settings file has this structure:

These settings are supported when you run projects locally:

By default, these settings are not migrated automatically when the project is published to Azure. Use the --publish-local-settings switch when you publish to make sure these settings are added to the function app in Azure. Note that values in ConnectionStrings are never published.

The function app settings values can also be read in your code as environment variables. For more information, see the Environment variables section of these language-specific reference topics:

When no valid storage connection string is set for AzureWebJobsStorage and the emulator isn't being used, the following error message is shown:

Missing value for AzureWebJobsStorage in local.settings.json. This is required for all triggers other than HTTP. You can run 'func azure functionapp fetch-app-settings <functionAppName>' or specify a connection string in local.settings.json.

Get your storage connection strings

Even when using the Microsoft Azure Storage Emulator for development, you may want to test with an actual storage connection. Assuming you have already created a storage account, you can get a valid storage connection string in one of the following ways:

• From the Azure portal, search for and select Storage accounts.

  Select your storage account, select Access keys in Settings, then copy one of the Connection string values.

• Use Azure Storage Explorer to connect to your Azure account. In the Explorer, expand your subscription, expand Storage Accounts, select your storage account, and copy the primary or secondary connection string.

• Use Core Tools to download the connection string from Azure with one of the following commands:

  • Download all settings from an existing function app:

  • Get the Connection string for a specific storage account:

    When you aren't already signed in to Azure, you're prompted to do so.

Create a function

To create a function, run the following command:

In version 3.x/2.x, when you run func new you are prompted to choose a template in the default language of your function app, then you are also prompted to choose a name for your function. In version 1.x, you are also prompted to choose the language.

Function code is generated in a subfolder with the provided function name, as you can see in the following queue trigger output:

You can also specify these options in the command using the following arguments:

For example, to create a JavaScript HTTP trigger in a single command, run:

To create a queue-triggered function in a single command, run:

Run functions locally

To run a Functions project, run the Functions host. The host enables triggers for all functions in the project. The start command varies, depending on your project language.

This command must be run in a virtual environment.

Note

Version 1.x of the Functions runtime requires the host command, as in the following example:

func start supports the following options:

When the Functions host starts, it outputs the URL of HTTP-triggered functions:

Important

When running locally, authorization isn't enforced for HTTP endpoints. This means that all local HTTP requests are handled as authLevel = 'anonymous'. For more information, see the HTTP binding article.

Passing test data to a function

To test your functions locally, you start the Functions host and call endpoints on the local server using HTTP requests. The endpoint you call depends on the type of function.

Note

Examples in this topic use the cURL tool to send HTTP requests from the terminal or a command prompt. You can use a tool of your choice to send HTTP requests to the local server. The cURL tool is available by default on Linux-based systems and Windows 10 build 17063 and later. On older Windows, you must first download and install the cURL tool.

For more general information on testing functions, see Strategies for testing your code in Azure Functions.

HTTP and webhook triggered functions

You call the following endpoint to locally run HTTP and webhook triggered functions:

Make sure to use the same server name and port that the Functions host is listening on. You see this in the output generated when starting the Function host. You can call this URL using any HTTP method supported by the trigger.

The following cURL command triggers the MyHttpTrigger quickstart function from a GET request with the name parameter passed in the query string.

The following example is the same function called from a POST request passing name in the request body:

You can make GET requests from a browser passing data in the query string. For all other HTTP methods, you must use cURL, Fiddler, Postman, or a similar HTTP testing tool.

Non-HTTP triggered functions

For all kinds of functions other than HTTP triggers and webhooks and Event Grid triggers, you can test your functions locally by calling an administration endpoint. Calling this endpoint with an HTTP POST request on the local server triggers the function.

To test Event Grid triggered functions locally, see Local testing with viewer web app.

You can optionally pass test data to the execution in the body of the POST request. This functionality is similar to the Test tab in the Azure portal.

You call the following administrator endpoint to trigger non-HTTP functions:

To pass test data to the administrator endpoint of a function, you must supply the data in the body of a POST request message. The message body is required to have the following JSON format:

Launching Python App On Mac Locally Free

The <trigger_input> value contains data in a format expected by the function. The following cURL example is a POST to a QueueTriggerJS function. In this case, the input is a string that is equivalent to the message expected to be found in the queue.

Using the func run command (version 1.x only)

Important

The func run command is only supported in version 1.x of the tools. For more information, see the topic How to target Azure Functions runtime versions.

In version 1.x, you can also invoke a function directly by using func run <FunctionName> and provide input data for the function. This command is similar to running a function using the Test tab in the Azure portal.

func run supports the following options:

For example, to call an HTTP-triggered function and pass content body, run the following command:

Publish to Azure

The Azure Functions Core Tools supports two types of deployment: deploying function project files directly to your function app via Zip Deploy and deploying a custom Docker container. You must have already created a function app in your Azure subscription, to which you'll deploy your code. Projects that require compilation should be built so that the binaries can be deployed.

Important

You must have the Azure CLI installed locally to be able to publish to Azure from Core Tools.

A project folder may contain language-specific files and directories that shouldn't be published. Excluded items are listed in a .funcignore file in the root project folder.

Deploy project files

To publish your local code to a function app in Azure, use the publish command:

This command publishes to an existing function app in Azure. You'll get an error if you try to publish to a <FunctionAppName> that doesn't exist in your subscription. To learn how to create a function app from the command prompt or terminal window using the Azure CLI, see Create a Function App for serverless execution. By default, this command uses remote build and deploys your app to run from the deployment package. To disable this recommended deployment mode, use the --nozip option.

Important

When you create a function app in the Azure portal, it uses version 3.x of the Function runtime by default. To make the function app use version 1.x of the runtime, follow the instructions in Run on version 1.x.You can't change the runtime version for a function app that has existing functions.

The following publish options apply for all versions:

The following publish options are supported only for version 2.x and later versions:

Deploy custom container

Azure Functions lets you deploy your function project in a custom Docker container. For more information, see Create a function on Linux using a custom image. Custom containers must have a Dockerfile. To create an app with a Dockerfile, use the --dockerfile option on func init.

The following custom container deployment options are available:

Monitoring functions

The recommended way to monitor the execution of your functions is by integrating with Azure Application Insights. You can also stream execution logs to your local computer. To learn more, see Monitor Azure Functions.

Application Insights integration

Launching Python App On Mac Locally Mac

Application Insights integration should be enabled when you create your function app in Azure. If for some reason your function app isn't connected to an Application Insights instance, it's easy to do this integration in the Azure portal.

Azure Functions makes it easy to add Application Insights integration to a function app from the Azure portal.

1. In the Azure portal, search for and select function app, and then choose your function app.

2. Select the Application Insights is not configured banner at the top of the window. If you don't see this banner, then your app might already have Application Insights enabled.

3. Expand Change your resource and create an Application Insights resource by using the settings specified in the following table.

   Setting	Suggested value	Description
   New resource name	Unique app name	It's easiest to use the same name as your function app, which must be unique in your subscription.
   Location	West Europe	If possible, use the same region as your function app, or one that's close to that region.

4. Select Apply.

   The Application Insights resource is created in the same resource group and subscription as your function app. After the resource is created, close the Application Insights window.

5. In your function app, select Configuration under Settings, and then select Application settings. If you see a setting named APPINSIGHTS_INSTRUMENTATIONKEY, Application Insights integration is enabled for your function app running in Azure.

Enable streaming logs

You can view a stream of log files being generated by your functions in a command-line session on your local computer.

Native streaming logs

Built-in log streaming

Use the logstream option to start receiving streaming logs of a specific function app running in Azure, as in the following example:

Live Metrics Stream

You can also view the Live Metrics Stream for your function app in a new browser window by including the --browser option, as in the following example:

This type of streaming logs requires that Application Insights integration be enabled for your function app.
