Website:https://typescript-play.js.org.

Differences fromhttps://www.typescriptlang.org/play:

• All strict options turned on by default
• More available compiler options
• Ability to switch TypeScript version
• More space for code
• More examples
• Quicker sharing, URL updates as you type
• Shorter sharing URLs

npm installnpm run setupnpm start

Playground relies onUNPKG to fetchmonaco-editor (containstypescript throughmonaco-typescript package).

In case ifmonaco-editor is not updated to the latest TypeScript, the latest version can be built withnpm run get-typescript latest and served locally.If you run into errors, the latest monaco version may be incompatible with the latest typescript version,in which case you'll need to update monaco-typescript upstream, or apply a patch locally (see the# Patches section inget-typescript.sh.

In case you want to serve some specific version of TypeScript locally you should runnpm run get-typescript <version>. For example, to serve TypeScript version 2.8.3 you should runnpm run get-typescript 2.8.3; npm start
