AppCode 2023.1 Help

Next.js

AppCode integrates with the Next.js React framework.

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 Next.js Support plugin on the Preferences | Plugins page, tab Marketplace, as described in Installing plugins from JetBrains repository.

Create a new Next.js application

The recommended way to start building a new Next.js application is the create-next-app package, which AppCode downloads and runs for you using npx. As a result, your development environment is preconfigured to use Next.js.

Of course, you can still download create-next-app yourself or create an empty AppCode project and install Next.js in it.

Generate a Next.js application with create-next-app

  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 Next.js.

  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 create-next-app list, select npx create-next-app.

      Alternatively, for npm version 5.1 and earlier, install the create-next-app package yourself by running npm install --save-dev next react react-dom in the Terminal Alt+F12. When creating an application, select the folder where the create-next-app package is stored.

    4. 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 Next.js-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 Next.js in an empty AppCode project

In this case, you will have to configure the build pipeline yourself. Learn more about adding Next.js to a project from the Next.js 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 Next.js in an empty project

  1. Open the empty project where you will use Next.js.

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

    npm install --save-dev next react react-dom

Start with an existing Next.js application

To continue developing an existing Next.js 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. 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.

  2. 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.
