AppCode 2023.1 Help


AppCode 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.

AppCode 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, AppCode 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 plugin is enabled in the settings. Press Ctrl+Alt+S to open the IDE settings and select Plugins. Click the Installed tab. In the search field, type JavaScript and TypeScript. For more details about plugins, see Managing plugins.

  3. Install and enable the Vite plugin on the Preferences | Plugins page, tab Marketplace, as described in Installing plugins from JetBrains repository.

Create a new Vite application

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

Generate a Vite application with create-vite

  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 Vite.

  3. In the right-hand pane:

    1. Specify the path to the folder where the project-related files will be stored.

    2. 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.

    3. 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.

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

    5. Optionally:

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

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

Install Vite in an empty AppCode 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 AppCode 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 (Alt+F12) , type:

    npm install --save-dev vite

Start with an existing Vite application

To continue developing an existing Vite application, open it in AppCode 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 AppCode 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 AppCode and was imported into it, AppCode 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 AppCode, 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.

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

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

Learn more from Project security.

Configure Vite in AppCode

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, AppCode understands the Vite configuration, resolves modules, and provides coding assistance in JavaScript and TypeScript files.

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

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

Choose how to detect Vite configuration

  1. Open the 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, AppCode 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).

      AppCode 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 AppCode, see the list of recognized Vite config names above.

      Select a vite configuration file manually
