RubyMine 2019.2 Help


RubyMine integrates with the Vue.js framework intended for developing user interfaces and advanced single-page applications.

Before you start

  1. Make sure you have Node.js on your computer.

  2. Install and activate the Vue.js repository plugin on the Plugins page as described in Managing plugins.

Creating a new Vue.js application

The recommended way to create a new Vue.js app is Vue CLI, which RubyMine downloads and runs for you using npx.

Of course, you can still download Vue CLI yourself or create an empty RubyMine project and install Vue.js in it.

To create an application

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

  2. In the left-hand pane, choose Vue.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 Vue CLI list, select npx --package @vue/cli vue.

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

    4. To bootstrap your application with babel and ESLint, select the Use the default project setup checkbox.

  4. When you click Create, RubyMine generates a Vue.js-specific project with all the required configuration files and downloads the necessary dependencies. You can view the progress in the Run tool window.

To create an empty RubyMine project

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

  2. In the left-hand pane, choose Empty Project.

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

  4. When you click Create, RubyMine creates and opens an empty project.

To install Vue.js in an empty project

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

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

    npm install vue

Starting with an existing Vue.js application

To continue developing an existing Vue.js application, open it in RubyMine and download the required dependencies.

To 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.

To check out the application sources from your version control

  1. Click Check out from Version Control on the Welcome screen or select VCS | Check out from Version Control from the main menu.

  2. Select your version control system from the list.

  3. In the VCS-specific dialog that opens, type your credentials and the repository to check out the application sources from.

To download the dependencies

Click Run 'npm install' in the popup:

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

Creating Vue.js components

RubyMine recognizes the .vue file type and provides a dedicated .vue file template for Vue.js components.

To create a Vue.js component

In the Project tool window, select the parent folder for the new component and choose Vue Component from the list.


You can also extract a new Vue.js component from an existing one without any copying and pasting but using a dedicated intention action or refactoring. All the data and methods used in the newly extracted template stay in the parent component. RubyMine passes them to the new component with props and copies the related styles.

To extract a component

  1. Select the template fragment to extract and invoke component extraction:

    • To use the intention action, press Alt+Enter, and then choose Extract Vue Component from the list.

    • To use the refactoring, choose Refactor | Extract | Extract Vue Component from the main menu or from the context menu of the selection.

  2. Type the name of the new component. If this name is already used or invalid, RubyMine shows a warning. Otherwise a new single-file component is created and imported into the parent component.

Coding assistance

In .vue files, RubyMine recognizes script, style, and template blocks. You can use JavaScript and TypeScript inside script tags, Style Sheet languages inside style tags, and HTML and Pug inside template tags.

When you use TypeScript inside a script tag, RubyMine invokes the TypeScript Language Service for type checking and shows detected errors in the Errors and Compile errors tabs of the TypeScript tool window.

Complete your code

  • By default, RubyMine provides code completion for ECMAScript 6 inside script blocks and for CSS inside style blocks.

    Vue.js: completion for ES6 inside <script> tag
  • Inside the template tag, code completion Ctrl+Space and navigation to the definition Ctrl+B for Vue.js components and attributes is available.

  • RubyMine also suggests completion for Vue.js properties, properties in the data object, computed properties, and methods.

Linting TypeScript in Vue.js components using TSLint

You can lint TypeScript code in your Vue.js single file components using typescript-tslint-plugin.

Because typescript-tslint-plugin works only with TypeScript that is installed in the current project, make sure the typescript package from your project node_modules folder is selected in the TypeScript field on the TypeScript page of the Settings/Preferences dialog (Ctrl+Alt+S).

Install and configure typescript-tslint-plugin

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

    npm install --save-dev typescript-tslint-plugin

  2. In the plugins property of your tsconfig.json file, type:

    { "compilerOptions": { "plugins": [{"name": "typescript-tslint-plugin"}] } }

  3. When you are using typescript-tslint-plugin, TSLint is running via the TypeScript Language Service so you can disable the TSLint integration with RubyMine to avoid duplicate error reporting.

    To do that, open the Settings/Preferences dialog (Ctrl+Alt+S), go to Languages and Frameworks | TyprScript | TSLint, and select Disable TSLint.

Generating code with Vue.js Live templates

With RubyMine, you can use a collection of Live templates for Vue.js adapted from the collection created by Sarah Drasner.

To use a Vue.js Live template

  1. Type the template's abbreviation or press Ctrl+J and select it from the list of available templates.

  2. To expand the template, press Tab.

  3. To move from one variable to another inside the template, press Tab again.

Reformatting Vue.js code with Prettier

Prettier is a tool to format .js, .ts, .css, .less, .scss, .vue, and .json code. With RubyMine, you can format selected code fragments as well as entire files or directories using the Reformat with Prettier action. RubyMine adds this action as soon as you install Prettier as a dependency in your project or globally on your computer. Learn more from Prettier.

To reformat code with Prettier

  • Select the code fragment to reformat in the editor or select a file or a folder in the Project tool window and press N/A or select Reformat with Prettier from the context menu.

  • Alternatively, press Ctrl+Shift+A and select Reformat with Prettier from the Find Action list.


RubyMine can apply the key code style rules from the Prettier's configuration to the RubyMine Code Style settings so that generated code (for example, after refactoring or quick-fix) and the code that is already processed with Prettier are formatted consistently.

To apply Prettier code style rules

  • In the project where Prettier is enabled, open package.json and click Yes in the pane at the top of the tab.

    Pane above package.json: apply Prettier code style

  • To re-apply the Prettier code style (after you've clicked No in the pane or modified the code style), press Ctrl+Shift+A and select Apply Prettier Code Style Rules from the Find Action list.
