On this page you will find a short Getting Started Guide that will walk you step by step from creating a web application to debugging and testing it.
Before you start
Creating a new application
- In the left-hand pane, choose one of the following options:
- Web Starter Kit
- React App
- React Native
In the right-hand pane, specify the path to the folder where the project-related files will be stored, and the version of the project template. Click Create.
To open the application sources that are already on your machine
To check out the application sources from your version control
Click Get from Version Control on the Welcome screen or select from the main menu.
In the invoked dialog, select your version control system from the list and specify the repository to check out the application sources from.
- ECMAScript 3
- ECMAScript 5.1
ECMAScript 6: This version adds support for the features introduced in ECMAScript 2015-2017 as well as some current proposals to the standard.
React JSX: This version adds support for the JSX syntax on top of ECMAScript 6
Flow: This version adds support for the Flow syntax.
Downloading npm dependencies
Before you start, make sure you have Node.js on your computer. If your application uses some tools, libraries, or frameworks, download the required packages.
To install a package in an empty project
If you already have a package.json file in your project
Right-click the package.json file in the editor or in the Project tool window and choose Run 'npm install' from the context menu.
npm installin the Terminal Alt+F12.
Configuring code completion for project dependencies
Viewing parameter hints
Parameter hints show the names of parameters in methods and functions to make your code easier to read. By default, parameter hints are shown only for values that are literals or function expressions but not for named objects.
To configure parameter hints
Select Parameter hints from the list, make sure the Show parameter hints checkbox is selected, and then specify the context where you want parameter hints shown.
For some methods and functions, CLion does not show parameter hints in any context. Click Black list... to view these methods and functions, possibly enable parameter hints for them, or add new items to the list.
CLion can generate import statements for modules, classes, components, and any other symbols that are exported. If you are using ES6 in your project, CLion can add missing import statements on the fly, when you complete ES6 symbols.
Alternatively, press Alt+Enter:
If there's more than one possible source of import, CLion shows a list of suggestions:
To add ES6 import statements on code completion
In the Settings/Preferences dialog Ctrl+Alt+S, go to . The Auto Import page opens.
CLion can also generate import statements for symbols defined in the project’s dependencies. Auto-import works for symbols from packages that contain TypeScript definition files (like in moment or redux) or sources written as ES modules.
Configuring syntax highlighting
Select the color scheme, accept the highlighting settings inherited from defaults or customize them as described in Configuring Colors and Fonts.
