Code Generation in TypeScript

warning

Starting from ReSharper 2022.2, active development of productivity features for JavaScript, TypeScript, JSON, CSS, and Protobuf is suspended, and these features are disabled by default. To enable them, select the corresponding checkboxes on the Environment | Products & Features page of ReSharper options Alt+R, O: JavaScript and TypeScript, CSS Language, and Protobuf.

ReSharper provides a variety of ways to generate boilerplate code. For example, you can use undeclared code symbols and automatically generate these symbols based on usages, generate type members, and more.

tip

Depending on your settings, stubs for new members can be generated in different ways. For example, they can throw new NotImplementedException(), return default value, or include code that will not compile. You can configure these and other preferences on the Code Editing | Members Generation page of ReSharper options Alt+R, O.

Generate code from usage

ReSharper lets you use code symbols (classes, methods, variables, and so on) before you declare them. When ReSharper detects an undeclared symbol, it suggests one or more quick-fixes for generating a declaration based on the usage, and then smartly adjust the declaration according to the usage context:

Generate Type Members

With ReSharper, you can quickly generate different type members. To view the list of available code generation options for the current type, press or choose ReSharper | Edit | Generate Code… in the main menu.

Generate constructors

The constructor generation wizard creates a non-default constructor that takes parameters for selected fields .

All generated constructors follow the same pattern where:

• Each field included in the constructor is initialized with a parameter.

• The name of the parameter is derived from the name of the corresponding field .

Implementing/overriding members

For inherited types, ReSharper provides two related code generation features:

• Implement missing members implements any interface members or abstract members missing from the current class.

• Override members does the same as Implement missing members, but it also overrides virtual members if applicable.

Generate properties

ReSharper will help you generate properties for all fields that you want to expose.
