TypeScript Playground
TypeScript Playground · Redmond, Washington, USA · founded 2012
What it is
TypeScript Playground is a free web environment for writing, running, and sharing TypeScript and JavaScript code. It accepts .ts, .tsx, .js, .jsx, and .d.ts files. Running code converts it to JavaScript, executes it in the browser session, and displays console output in Logs. The single-document editor is intended for teaching and experimenting without setup. Users can select supported TypeScript builds, including beta, nightly, pull request, and older versions. The TS Config panel exposes a focused set of compiler options, while twoslash annotations can configure options beyond that selection. Shareable URLs can retain code, compiler flags, and settings. Examples and tutorials cover TypeScript, JavaScript, and release changes. The Export menu can create Markdown, open code in TypeScript AST Viewer, or export a project to CodeSandbox or StackBlitz. Plugins are supported, including examples such as Presentation Mode, Clippy, TSQuery, Collaborate, and Transformer. The editor focuses on one text file; its mobile layout uses a single pane and does not show transpiled JavaScript beside source code. The maker was founded in 2012 and is headquartered in Redmond, Washington, USA.
For and against
For
- Free browser-based environment
- Runs code and shows console output
- URLs can preserve code and compiler settings
- Supports plugins and multiple TypeScript builds
Against
- Focused on a single text file
- Mobile layout does not show transpiled JavaScript alongside source
The verdict
TypeScript Playground offers a focused place to write, run, and share code, with compiler controls, examples, and exports. For a broader Node project environment, its documentation points users to CodeSandbox or StackBlitz.
Who it suits
It suits learners and developers who want to try or share TypeScript and JavaScript code without setting up a project. Its single-file scope is suited to experiments rather than general-purpose Node project work.
