npm allows you to install and manage packages for use in your Node.js applications. Visual Studio makes it easy to interact with npm and issue npm commands through the UI or directly. If you're unfamiliar with npm and want to learn more, go to the npm documentation.

Intellisense in Visual Studio Code. First, you save the JSON above as address.schema.json. Here is the folder structure. Project/ ├── address/ │ ├── data.json │ └── data.yaml └── address.schema.json. If you save the schemas files as.schema.json instead of.json, Visual Studio Code has Intellisense for JSON Schema.

A very simple extension that will let you convert selected text to a Go struct if it's valid JSON. Can be run through the command pallete or the editor context menu inside supported files with the JSON to Go command. This is the initial release and I welcome any suggestions. Visual Studio Code creates a directory and a file.vscodelaunch.json in the root of your workspace folder to store the debug configuration. If your files are in a Git repository, you typically want to commit the launch.json file. The contents of the launch.json file are. For workspace settings JSON, the JSON file is located in a folder of the root directory called.vscode, you can create it yourself if it is not there. By default, VS Code shows the Settings editor, but you can still edit the underlying settings.json file by using the Open Settings (JSON) command from your command palette or by changing your.

Visual Studio integration with npm is different depending on your project type.

Important

npm expects the node_modules folder and package.json in the project root. If your app's folder structure is different, you should modify your folder structure if you want to manage npm packages using Visual Studio.

Node.js projects

For Node.js projects, you can perform the following tasks:

These features work together and synchronize with the project system and the package.json file in the project.

Prerequisites

You need the Node.js development workload and the Node.js runtime installed to add npm support to your project. For detailed steps, see Create a Node.js project.

Note

For existing Node.js projects, use the From existing Node.js code solution template or the Open folder (Node.js) project type to enable npm in your project.

Install packages from Solution Explorer (Node.js)

For Node.js projects, the easiest way to install npm packages is through the npm package installation window. To access this window, right-click the npm node in the project and select Install New npm Packages.

In this window you can search for a package, specify options, and install.

• Dependency type - Chose between Standard, Development, and Optional packages. Standard specifies that the package is a runtime dependency, whereas Development specifies that the package is only required during development.
• Add to package.json - Recommended. This configurable option is deprecated.
• Selected version - Select the version of the package you want to install.
• Other npm arguments - Specify other standard npm arguments. For example, you can enter a version value such as @~0.8 to install a specific version that is not available in the versions list.

You can see the progress of the installation in the npm output in the Output window. This may take some time.

Tip

You can search for scoped packages by prepending the search query with the scope you're interested in, for example, type @types/mocha to look for TypeScript definition files for mocha. Also, when installing type definitions for TypeScript, you can specify the TypeScript version you're targeting by adding @ts2.6 in the npm argument field.

Manage installed packages in Solution Explorer (Node.js)

npm packages are shown in Solution Explorer. The entries under the npm node mimic the dependencies in the package.json file.

Package status

• - Installed and listed in package.json
• - Installed, but not explicitlylisted in package.json
• - Not installed, but listed in package.json

Right-click the npm node to take one of the following actions:

• Install New npm Packages Opens the UI to install new packages.
• Install npm Packages Runs the npm install command to install all packages listed in package.json. (Runs npm install.)
• Update npm Packages Updates packages to the latest versions, according to the semantic versioning (SemVer) range specified in package.json. (Runs npm update --save.). SemVer ranges are typically specified using '~' or '^'. For more information, package.json configuration.

Right-click a package node to take one of the following actions:

• Install npm Package(s) Runs the npm install command to install the package version listed in package.json. (Runs npm install.)
• Update npm Package(s) Updates the package to the latest version, according to the SemVer range specified in package.json. (Run npm update --save.) SemVer ranges are typically specified using '~' or '^'.
• Uninstall npm Package(s) Uninstalls the package and removes it from package.json (Runs npm uninstall --save.)

Right-click a package node or the npm node to take one of the following actions:

• Install missing packages that are listed in package.json
• Update npm packages to the latest version
• Uninstall a package and remove from package.json

Note

For help resolving issues with npm packages, see Troubleshooting.

Use the .npm command in the Node.js Interactive Window (Node.js)

You can also use the .npm command in the Node.js Interactive Window to executenpm commands. To open the window, right-click the project in Solution Explorer and choose Open Node.js Interactive Window.

In the window, you can use commands such as the following to install a package:

.npm install azure@4.2.3

Tip

By default, npm will execute in your project's home directory. If you have multiple projectsin your solution specify the name or the path of the project in brackets..npm [MyProjectNameOrPath] install azure@4.2.3

Tip

If your project doesn't contain a package.json file, use .npm init -y to create a new package.json filewith default entries.

ASP.NET Core projects

For projects such as ASP.NET Core projects, you can integrate npm support in your project and use npm to install packages.

Note

For ASP.NET Core projects, you can also use Library Manager or yarn instead of npm to install client-side JavaScript and CSS files.

Add npm support to a project (ASP.NET Core)

If your project does not already include a package.json file, you can add one to enable npm support by adding a package.json file to the project.

1. If you don't have Node.js installed, we recommend you install the LTS version from the Node.js website for best compatibility with outside frameworks and libraries.

   npm requires Node.js.

2. To add the package.json file, right-click the project in Solution Explorer and choose Add > New Item. Choose the npm Configuration File, use the default name, and click Add.

   If you don't see the npm Configuration File listed, Node.js development tools are not installed. You can use the Visual Studio Installer to add the Node.js development workload. Then repeat the previous step.

3. Include one or more npm packages in the dependencies or devDependencies section of package.json. For example, you might add the following to the file:

When you save the file, Visual Studio adds the package under the Dependencies / npm node in Solution Explorer. If you don't see the node, right-click package.json and choose Restore Packages.

Note

In some scenarios, Solution Explorer may not show the correct status for installed npm packages. For more information, see Troubleshooting.

Install packages using package.json (ASP.NET Core)

For projects with npm included, you can configure npm packages using package.json. Right-click the npm node in Solution Explorer and choose Open package.json.

IntelliSense in package.json helps you select a particular version of an npm package.

When you save the file, Visual Studio adds the package under the Dependencies / npm node in Solution Explorer. If you don't see the node, right-click package.json and choose Restore Packages.

It may take several minutes to install a package. Check progress on package installation by switching to npm output in the Output window.

Troubleshooting npm packages

• npm requires Node.js If you don't have Node.js installed, we recommend you install the LTS version from the Node.js website for best compatibility with outside frameworks and libraries.

• For Node.js projects, you must have the Node.js development workload installed for npm support.

• In some scenarios, Solution Explorer may not show the correct status for installed npm packages due to a known issue described here. For example, the package may appear as not installed when it is installed. In most cases, you can update Solution Explorer by deleting package.json, restarting Visual Studio, and re-adding the package.json file as described earlier in this article. Or, when installing packages, you can use the npm Output window to verify installation status.

• In some ASP.NET Core scenarios, the npm node in Solution Explorer may not be visible after your build the project. To make the node visible again, right-click the project node and choose Unload Project. Then right-click the project node and choose Reload Project.

• If you see any errors when building your app or transpiling TypeScript code, check for npm package incompatibilities as a potential source of errors. To help identify errors, check the npm Output window when installing the packages, as described previously in this article. For example, if one or more npm package versions has been deprecated and results in an error, you may need to install a more recent version to fix errors. For information on using package.json to control npm package versions, see package.json configuration.

Visual Studio Code is a cross-platform script editor by Microsoft. Together with thePowerShell extension, it provides a rich and interactive script editing experience, makingit easier to write reliable PowerShell scripts. Visual Studio Code with the PowerShell extension isthe recommended editor for writing PowerShell scripts.

It supports the following PowerShell versions:

• PowerShell 7 and up (Windows, macOS, and Linux)
• PowerShell Core 6 (Windows, macOS, and Linux)
• Windows PowerShell 5.1 (Windows-only)

Note

Visual Studio Code is not the same as Visual Studio.

Getting started

Before you begin, make sure PowerShell exists on your system. For modern workloads on Windows,macOS, and Linux, see the following links:

For traditional Windows PowerShell workloads, see Installing Windows PowerShell.

Important

The Windows PowerShell ISE is still available for Windows. However, it is no longer inactive feature development. The ISE does not work with PowerShell 6 and higher. As a component ofWindows, it continues to be officially supported for security and high-priority servicing fixes.We have no plans to remove the ISE from Windows.

Editing with Visual Studio Code

1. Install Visual Studio Code. For more information, see the overviewSetting up Visual Studio Code.

   There are installation instructions for each platform:

   • Windows: follow the installation instructions on theRunning Visual Studio Code on Windows page.
   • macOS: follow the installation instructions on theRunning Visual Studio Code on macOS page.
   • Linux: follow the installation instructions on theRunning Visual Studio Code on Linux page.

2. Install the PowerShell Extension.

   1. Launch the Visual Studio Code app by typing code in a console or code-insidersif you installed Visual Studio Code Insiders.

   2. Launch Quick Open on Windows or Linux by pressing Ctrl+P. On macOS,press Cmd+P.

   3. In Quick Open, type ext install powershell and press Enter.

   4. The Extensions view opens on the Side Bar. Select the PowerShell extension from Microsoft.You should see a Visual Studio Code screen similar to the following image:

   5. Click the Install button on the PowerShell extension from Microsoft.

   6. After the install, if you see the Install button turn into Reload, Click on Reload.

   7. After Visual Studio Code has reloaded, you're ready for editing.

For example, to create a new file, click File > New. To save it, click File > Save and thenprovide a file name, such as HelloWorld.ps1. To close the file, click the X next to the filename. To exit Visual Studio Code, File > Exit.

Installing the PowerShell Extension on Restricted Systems

Some systems are set up to require validation of all code signatures. You may receive the followingerror:

This problem can occur when PowerShell's execution policy is set by Windows Group Policy. Tomanually approve PowerShell Editor Services and the PowerShell extension for Visual Studio Code,open a PowerShell prompt and run the following command:

You're prompted with Do you want to run software from this untrusted publisher? Type A to runthe file. Then, open Visual Studio Code and check that the PowerShell extension is functioningproperly. If you still have problems getting started, let us know on GitHub issues.

Note

The PowerShell extension for Visual Studio Code does not support running in constrained languagemode. For more information, see GitHub issue #606.

Choosing a version of PowerShell to use with the extension

With PowerShell Core installing side-by-side with Windows PowerShell, it's now possible to use aspecific version of PowerShell with the PowerShell extension. This feature looks at a few well-knownpaths on different operating systems to discover installations of PowerShell.

Use the following steps to choose the version:

1. Open the Command Palette on Windows or Linux withCtrl+Shift+P. On macOS, useCmd+Shift+P.
2. Search for Session.
3. Click on PowerShell: Show Session Menu.
4. Choose the version of PowerShell you want to use from the list, for example: PowerShell Core.

If you installed PowerShell to a non-typical location, it might not show up initially in the SessionMenu. You can extend the session menu by adding your own custom pathsas described below.

Note

The PowerShell session menu can also be accessed from the green version number in the bottom rightcorner of status bar. Clicking this version number opens the session menu.

Configuration settings for Visual Studio Code

First, if you're not familiar with how to change settings in Visual Studio Code, we recommendreading Visual Studio Code's settings documentation.

After reading the documentation, you can add configuration settings in settings.json.

If you don't want these settings to affect all files types, Visual Studio Code also allowsper-language configurations. Create a language-specific setting by putting settings in a[<language-name>] field. For example:

Tip

For more information about file encoding in Visual Studio Code, see Understanding file encoding.

Also, check out How to replicate the ISE experience in Visual Studio Code for othertips on how to configure Visual Studio Code for PowerShell editing.

Adding your own PowerShell paths to the session menu

You can add other PowerShell executable paths to the session menu through theVisual Studio Code setting:powershell.powerShellAdditionalExePaths.

Add an item to the list powershell.powerShellAdditionalExePaths or create the list if it doesn'texist in your settings.json:

Each item must have:

• exePath: The path to the pwsh or powershell executable.
• versionName: The text that will show up in the session menu.

To set the default PowerShell version, set the value powershell.powerShellDefaultVersion to thetext displayed in the session menu (also known as the versionName):

Json Schema Visual Studio Code

After you've configured this setting, restart Visual Studio Code or to reload the current VisualStudio Code window from the Command Palette, type Developer: Reload Window.

If you open the session menu, you now see your additional PowerShell versions!

Note

If you build PowerShell from source, this is a great way to test out your local build ofPowerShell.

Using an older version of the PowerShell Extension for Windows PowerShell v3 and v4

The current PowerShell extension doesn't support PowerShell v3 and v4. However, you canuse the last version of the extension that supports PowerShell v3 and v4.

Caution

There will be no additional fixes to this older version of the extension. It's provided 'AS IS'but is available for you if you are still using Windows PowerShell v3 and Windows PowerShell v4.

First, open the Extension pane and search for PowerShell. Then click the gear and selectInstall another version....

Then select the 2020.1.0 version. This version of the extension was the last version tosupport v3 and v4. Be sure to add the following setting so that your extension version doesn'tupdate automatically:

Version 2020.1.0 will work for the foreseeable future. However, Visual Studio Code couldimplement a change that breaks this version of the extension. Because of this, and lack of support,we recommend:

• Upgrading to Windows PowerShell 5.1
• Install PowerShell 7, which is a side-by-side install to Windows PowerShell and works thebest with the PowerShell extension

Debugging with Visual Studio Code

No-workspace debugging

In Visual Studio Code version 1.9 (or higher), you can debug PowerShell scripts without opening thefolder that contains the PowerShell script.

Launch Json Visual Studio Code

1. Open the PowerShell script file with File > Open File...
2. Set a breakpoint - select a line then press F9
3. Press F5 to start debugging

You should see the Debug actions pane appear which allows you to break into the debugger,step, resume, and stop debugging.

Workspace debugging

Workspace debugging refers to debugging in the context of a folder that you've opened from theFile menu using Open Folder.... The folder you open is typically your PowerShell projectfolder or the root of your Git repository. Workspace debugging allows you to define multiple debugconfigurations other than just debugging the currently open file.

Follow these steps to create a debug configuration file:

1. Open the Debug view on Windows or Linux by pressingCtrl+Shift+D. On macOS, pressCmd+Shift+D.

2. Click the create a launch.json file link.

3. From the Select Environment prompt, choose PowerShell.

4. Choose the type of debugging you'd like to use:

   • Launch Current File - Launch and debug the file in the currently active editor window
   • Launch Script - Launch and debug the specified file or command
   • Interactive Session - Debug commands executed from the Integrated Console
   • Attach - Attach the debugger to a running PowerShell Host Process

Visual Studio Code creates a directory and a file .vscodelaunch.json in the root of yourworkspace folder to store the debug configuration. If your files are in a Git repository, youtypically want to commit the launch.json file. The contents of the launch.json file are:

This file represents the common debug scenarios. When you open this file in the editor, you see anAdd Configuration... button. You can click this button to add more PowerShell debugconfigurations. One useful configuration to add is PowerShell: Launch Script. With thisconfiguration, you can specify a file containing optional arguments that are used whenever youpress F5 no matter which file is active in the editor.

After the debug configuration is established, you can select which configuration you want to useduring a debug session. Select a configuration from the debug configuration drop-down in theDebug view's toolbar.
