PyCharm supports developing and running TypeScript
source code. PyCharm recognizes
*.ts files, and allows you to edit them providing full
range of coding assistance without any additional steps from your side. TypeScript files are marked with
Preparing for TypeScript development
- Make sure the Node.js plugin is installed and enabled. The plugin is not bundled with PyCharm, but it can be installed from the JetBrains plugin repository as described in Installing, Updating and Uninstalling Repository Plugins and Enabling and Disabling Plugins.
TypeScript support includes:
- Code completion for keywords, labels, variables, parameters, and functions.
- Error and syntax highlighting.
- Code formatting and folding.
- Numerous code inspections and quick-fixes.
This assistance can be provided either by PyCharm itself, or based on the data from the built-in TypeScript compiler, or through integration with the TypeScript Language Service. Provision of coding assistance is configured on the TypeScript page of the Settings / Preferences Dialog:
- Select the Use TypeScript Service check box to get native support from the TypeScript Language Service according to the up-to-date specifications. In this case syntax and error highlighting is performed based on the annotations retrieved from the TypeScript Language Service while code completion lists contain both suggestions from the TypeScript Language Service and suggestions calculated by PyCharm itself. To get only suggestions from PyCharm, click Configure and clear the Code completion check box in the Service Options dialog box that opens.
- Select the Enable TypeScript Compiler check box to active the built-in compiler. When the check box is selected, syntax highlighting and code completion are provided based only on the data from the built-in Typescript compiler. After you select this check box, the fields below in the area become active and you can configure the behaviour of the compiler. By default, the check box is cleared.
- Common refactoring procedures, such as extract method , inline, rename/move, etc.
- TypeScript-specific refactoring procedures, such as change signature, extract parameter, extract variable.
- Code generation
- Generating code stubs based on file templates during file creation.
- Ability to create line and block comments (Ctrl+Slash/Ctrl+Shift+Slash).
importstatements for modules, classes, and any other symbol that can be exported and called as a type, see Creating Imports, section Importing TypeScript Symbols.
You can also configure the type of quotes to be used in
importstatements by choosing Double quotes or Single quotes from the String literal type drop-down list on the Code Style. TypeScript page of the Settings dialog box.
- Configuring automatic insertion or skipping the public access modifier in generated code.
- Navigation and search through the source code:
- Navigating with Structure View.
- (Ctrl+Alt+B) from overridden method / subclassed class.
