JetBrains Rider supports developing, running, and debugging TypeScript source code. JetBrains Rider recognizes .ts and .tsx files and provides full range of coding assistance for editing them without any additional steps from your side. TypeScript files are marked with the TypeScript file icon.

TypeScript-aware coding assistance includes completion for keywords, labels, variables, parameters, and functions, error and syntax highlighting, formatting, numerous code inspections and quick-fixes, as well as common and TypeScript-specific refactoring. JetBrains Rider also verifies TypeScript code on the fly and shows errors in a dedicated Problems tool window.

Compilation errors are reported in the TypeScript tool window. Learn more from Compiling TypeScript into JavaScript.
