Vite

Last modified: 08 June 2023

Required plugins:

JavaScript and TypeScript, Vite -  The plugins are bundled with JetBrains Rider and enabled by default.

JetBrains Rider 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.

JetBrains Rider 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, JetBrains Rider 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.

note

JetBrains Rider integration with Vite requires that the vite package should be installed in your project or globally. Therefore, either create an application with create-vite or install the vite package manually. To work with an existing Vite app, make sure your package.json lists Vite before running npm install.

Before you start

Create a new Vite application

The recommended way to start a new Vite application is the create-vite package, which JetBrains Rider 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 JetBrains Rider project and install Vite in it.

tip

Learn more about starting with Vite from the Vite.js official website.

Generate a Vite application with create-vite

Install Vite in an empty JetBrains Rider 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 JetBrains Rider project

  1. Click Create New Project on the Welcome screen or select File | New | Project from the main menu. The New Project dialog opens.

  2. In the left-hand pane, choose Empty Project. In the right-hand pane, specify the application folder and click Create.

Install Vite in an empty project

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

  2. In the embedded Terminal (Ctrl+`) , type:

    npm install --save-dev vite

Start with an existing Vite application

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

Open the application sources that are already on your machine

  • Click Open 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 JetBrains Rider 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 JetBrains Rider and was imported into it, JetBrains Rider displays a dialog where you can decide how to handle this project with unfamiliar source code.

Select one of the following options:

  • Preview in Safe Mode: in this case, JetBrains Rider 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.

    JetBrains Rider 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, JetBrains Rider opens and loads a project. That means project is initialized, project's plugins are resolved, dependencies are added, and all JetBrains Rider features are available.

  • Don't Open: in this case, JetBrains Rider doesn't open the project.

tip

Projects created from the Welcome screen or via File | New | Project as described in are automatically considered trusted.

Configure Vite in JetBrains Rider

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.

Specify the Vite configuration files to use

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

In JetBrains Rider, you can choose between two configuration modes - automatic and manual.

With automatic configuration, JetBrains Rider 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 JetBrains Rider, see the list of recognized Vite config names below.

Choose how to detect Vite configuration

  1. Open the Settings/Preferences 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, JetBrains Rider 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).

      JetBrains Rider 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 JetBrains Rider, see the list of recognized Vite config names above.

      Select a vite configuration file manually
