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
To provide code completion for project dependencies, JetBrains Rider automatically creates a node_modules library. In JetBrains Rider, a library is a file or a set of files whose functions and methods are added to JetBrains Rider's internal knowledge in addition to the functions and methods that JetBrains Rider retrieves from the project code that you edit.
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.
Configure parameter hints
Open the Settings/Preferences dialog Ctrl+Alt+S and go to .
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, JetBrains Rider does not show parameter hints in any context. Click Exclude list... to view these methods and functions, possibly enable parameter hints for them, or add new items to the list.
JetBrains Rider can generate import statements for modules, classes, components, and any other symbols that are exported. If you are using ES6 in your project, JetBrains Rider 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, JetBrains Rider shows a list of suggestions:
JetBrains Rider 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.
To configure the appearance of
importstatements, open the Settings/Preferences dialog Ctrl+Alt+S, go to , and use the controls in the Imports tab, see Imports tab for details.
Configuring syntax highlighting
