IntelliJ IDEA 2022.3 Help

Vite

IntelliJ IDEA integrates with the Vite build tool that improves the frontend development experience. Vite consists of a dev server and a build command. The build server serves your source files over native ES modules. The build command bundles your code with Rollup, which is pre-configured to output highly optimized static assets for production.

IntelliJ IDEA supports tsconfig.json and jsconfig.json path mappings in Vue style tags and recognizes Vite aliases.

In projects that consist of multiple modules with different Vite configurations, IntelliJ IDEA can automatically detect the relevant configuration file for each module and use the module resolution rules from it, see Specifying the Vite configuration file to use below.

Before you start

  1. Download and install Node.js.

  2. Make sure the JavaScript and TypeScript and Vite required plugins are enabled on the Settings | Plugins page, tab Installed, see Managing plugins for details.

Create a new Vite application

The recommended way to start a new Vite application is the create-vite package, which IntelliJ IDEA downloads and runs for you using npx. As a result, your development environment is preconfigured to use Vite and a basic template for one of the popular frameworks.

Of course, you can still download create-vite yourself or create an empty IntelliJ IDEA project and install Vite in it.

Generate a Vite application with create-vite

  1. Select File | New | Project from the main menu or click the New Project button on the Welcome screen.

  2. In the New Project dialog, select Vite in the left-hand pane.

  3. In the right-hand part of the wizard, specify the project name and the folder to create it in.

  4. Make sure that Vite is selected in Project type.

    In the Node Interpreter field, specify the Node.js interpreter to use. Select a configured interpreter from the list or choose Add to configure a new one.

    From the Vite list, select npx create-vite.

    Alternatively, for npm version 5.1 and earlier, install the create-vite package yourself by running npm install --g create-vite in the Terminal Alt+F12. When creating an application, select the folder where the create-vite package is stored.

  5. From the Template list, select the community maintained Vite template that targets the framework you are going to use in your application.

  6. Optionally:

    To use TypeScript instead of JavaScript, select the Use TypeScript template checkbox. IntelliJ IDEA will generate .ts files for your application and a tsconfig.json configuration file.

  7. When you click Create, IntelliJ IDEA generates a Vite-specific project with all the required configuration files and downloads the required dependencies. IntelliJ IDEA also creates an npm start and JavaScript Debug configurations with default settings for running or debugging your application.

Install Vite in an empty IntelliJ IDEA project

In this case, you will have to configure the build pipeline yourself. Learn more about adding Vite to a project from the Vite official website.

Create an empty IntelliJ IDEA project

  1. Select File | New | Project from the main menu or click the New Project button on the Welcome screen.

  2. In the New Project dialog, select Empty Project.

  3. Name the new project and change its location if necessary, then click Create.

Install Vite in an empty project

  1. Open the empty project where you will use Vite.

  2. In the embedded Terminal (Alt+F12) , type:

    npm install --save-dev vite

Start with an existing Vite application

To continue developing an existing Vite application, open it in IntelliJ IDEA and download the required dependencies.

Open the application sources that are already on your machine

  • Click Open or Import on the Welcome screen or select File | Open from the main menu. In the dialog that opens, select the folder where your sources are stored.

Check out the application sources from your version control

  1. Click Get from VCS on the Welcome screen.

    Alternatively, select File | New | Project from Version Control or Git | Clone… from the main menu.

    Instead of Git in the main menu, you may see any other Version Control System that is associated with your project. For example, Mercurial or Perforce.

  2. In the dialog that opens, select your version control system from the list and specify the repository to check out the application sources from. See Check out a project (clone) for details.

Download the dependencies

  1. Make sure your package.json lists the vite package under dependencies or devDependencies. That is necessary because IntelliJ IDEA integration with Vite, especially autodetecting configuration files, requires that the vite package should be installed in your project or globally.

  2. Click Run 'npm install' or Run 'yarn install' in the popup:

    Opening an Angular application and downloading the dependencies from package.json

    You can use npm, Yarn 1, or Yarn 2, see npm and Yarn for details.

  3. Select Run 'npm install' or Run 'yarn install' from the context menu of package.json in the editor or in the Project tool window.

Project security

When you open a project that was created outside IntelliJ IDEA and was imported into it, IntelliJ IDEA displays a dialog where you can decide how to handle this project with unfamiliar source code.

Untrusted project warning

Select one of the following options:

  • Preview in Safe Mode: in this case IntelliJ IDEA, opens the project in a preview mode. It means that you can browse the project's sources but you cannot run tasks and script or run/debug your project.

    IntelliJ IDEA displays a notification on top of the editor area, and you can click the Trust project… link and load your project at any time.

  • Trust Project: in this case, IntelliJ IDEA opens and loads a project. That means project is initialized, project's plugins are resolved, dependencies are added, and all IntelliJ IDEA features are available.

  • Don't Open: in this case IntelliJ IDEA doesn't open the project.

Learn more from Project security.

Configure Vite in IntelliJ IDEA

Create Vite configuration files

  • Create one or several configuration files depending on your project structure: select a parent folder in the Project tool window and then select New | JavaScript file from the context menu.

    Create a Vite configuration file

    The acceptable names are vite.config.js/vite.config.ts, vite.config.mjs, or vite.config.cjs.

    Learn more from the Vite official website.

  • If necessary, use alias that will be later recognized in import statements. Make sure you specify absolute paths in definitions of aliases. Learn more from the Vite official website.

    Completing alias in import statements

Specify the Vite configuration files to use

Based on the analysis of a Vite configuration file, IntelliJ IDEA understands the Vite configuration, resolves modules, and provides coding assistance in JavaScript and TypeScript files.

In IntelliJ IDEA, you can choose between two configuration modes - automatic and manual.

With automatic configuration, IntelliJ IDEA auto-detects the relevant Vite configuration file for each JavaScript or TypeScript file.

With manual configuration, you specify the Vite configuration file to use in your project. Manual configuration is useful if the name of your Vite configuration file is not recognized by IntelliJ IDEA, see the list of recognized Vite config names below.

Choose how to detect Vite configuration

  1. Open the Settings dialog (Ctrl+Alt+S) and go to Languages & Frameworks | JavaScript | Vite.

  2. In the Detect Vite configuration files for module resolution area, select one of the following options:

    • Automatically: In this mode, for a JavaScript or TypeScript file, IntelliJ IDEA will first look for a Vite configuration file in the folder where this JavaScript or TypeScript file is located, then in its parent folder, and so on.

      As a result, if your project consists of multiple modules with different Vite configurations, each module will use the module resolution rules from its own Vite configuration file (if such config is found).

      IntelliJ IDEA recognizes JavaScript or TypeScript Vite configuration files with the following names and in the following order:

      • vite.config.js/vite.config.ts

      • vite.config.mjs

      • vite.config.cjs

    • Manually: In the Configuration file field, specify the location of the Vite config to use.

      In this mode, the resolution rules from the specified configuration file will be applied to all modules in your project.

      Select this option if the name of your Vite configuration file is not recognized by IntelliJ IDEA, see the list of recognized Vite config names above.

      Select a vite configuration file manually
