If you open a file that has errors or warnings, they will be rendered inline with the text and in the overview ruler.

You can click on the summary or press ⇧⌘M (Windows, Linux Ctrl+Shift+M) to display the PROBLEMS panel with a list of all current errors.

In the Status bar, there is a summary of all errors and warnings counts.

The TypeScript language service will analyze your program for coding problems and report errors and warnings: If you'd like to see snippets, you can specify the order relative to suggestions at the top ( "top"), at the bottom ( "bottom"), or inlined ordered alphabetically ( "inline"). Tip: You can disable snippets by setting editor.snippetSuggestions to "none" in your settings file. See User Defined Snippets for more information.

You can install extensions to get additional snippets or define your own snippets for TypeScript.

In addition to smart code completions, VS Code also includes basic TypeScript snippets that are suggested as you type. Use ⇧⌘Space (Windows, Linux Ctrl+Shift+Space) to manually trigger signature help. Signature help is shown automatically when you type a ( or, within a function call. Signature helpĪs you write a TypeScript function call, VS Code shows information about the function signature and highlights the parameter that you are currently completing: You can also show the hover information at the current cursor position with the ⌘K ⌘I (Windows, Linux Ctrl+K Ctrl+I) keyboard shortcut. Hover over a TypeScript symbol to quickly see its type information and relevant documentation: VS Code provides IntelliSense for individual TypeScript files as well as TypeScript tsconfig.json projects. IntelliSense shows you intelligent code completion, hover information, and signature help so that you can write code more quickly and correctly.

The type information has been removed and let is now var. If you open helloworld.js, you'll see that it doesn't look very different from helloworld.ts. If you have Node.js installed, you can run node helloworld.js. This will compile and create a new helloworld.js JavaScript file. To compile your TypeScript code, you can open the Integrated Terminal ( ⌃` (Windows, Linux Ctrl+`)) and type tsc helloworld.ts. let message : string = 'Hello World' console. You'll notice the TypeScript keyword let and the string type declaration. įrom the File Explorer, create a new file called helloworld.ts. Create a new folder HelloWorld and launch VS Code. Let's start with a simple Hello World Node.js example. tsc -versionĪnother option is to install the TypeScript compiler locally in your project ( npm install -save-dev typescript) and has the benefit of avoiding possible interactions with other TypeScript projects you may have. You can test your install by checking the version. If you have npm installed, you can install TypeScript globally ( -g) on your computer by: npm install -g typescript

The easiest way to install TypeScript is through npm, the Node.js Package Manager. You will need to install the TypeScript compiler either globally or in your workspace to transpile TypeScript source code to JavaScript ( tsc HelloWorld.ts). Visual Studio Code includes TypeScript language support but does not include the TypeScript compiler, tsc. It offers classes, modules, and interfaces to help you build robust components. TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.

Configure IntelliSense for cross-compiling.
