TypeScript Playground
TypeScript Playground is a free browser environment for writing, running, and sharing TypeScript and JavaScript code.
What TypeScript Playground is
TypeScript Playground is a free browser environment for writing, running, and sharing TypeScript and JavaScript code. It accepts .ts, .tsx, .js, .jsx, and .d.ts files. The Run button converts code to JavaScript, executes it in the current browser session, and displays console output in the Logs tab; that session can also be used to experiment with browser DOM APIs. The editor is designed around one text document, making it useful for teaching and trying code without setup. Users can select supported TypeScript builds, including beta, nightly, pull request, and older builds. The TS Config panel offers a focused selection of compiler options, while twoslash annotations can set options outside that selection. URLs can retain code, compiler flags, and settings for sharing. The Export menu can produce Markdown, open code in tools such as TypeScript AST Viewer, or export a project to CodeSandbox or StackBlitz. Plugins are supported, with examples including Presentation Mode, Clippy, TSQuery, Collaborate, and Transformer. The mobile layout uses a single-pane editor, so it cannot show transpiled JavaScript alongside source there.
Good
- Runs code in the browser and displays console output.
- Shareable URLs can retain code and settings.
- Supports several TypeScript build versions.
- Exports Markdown and projects to CodeSandbox or StackBlitz.
Watch out
- Focused on a single text document.
- Mobile layout does not show transpiled JavaScript beside source.
- General-purpose Node projects require another environment.
Who it suits
It suits learners, teachers, and developers who want to experiment with TypeScript or JavaScript in a browser without setting up a project. Its single-document focus is useful for examples and small experiments rather than general-purpose Node projects.
Verdict
TypeScript Playground offers a no-setup way to teach, run, and share code in one document. For a broader Node project environment, its documentation points users to CodeSandbox or StackBlitz.
