Free online TypeScript compiler and editor
JDoodle is an online IDE that has served the programming community since 2013. You write, compile, and run code in the browser for TypeScript and many other languages, without installing a toolchain.
What you see on this page is JDoodle’s free TypeScript compiler. Write TypeScript in the editor, press Execute, and JDoodle runs it on its servers. You do not install TypeScript, and you do not need a JDoodle account to run code.
Online TypeScript editor
JDoodle’s TypeScript editor on this page highlights syntax, completes as you type, matches brackets, and folds blocks. It is an online TypeScript editor and a compiler together: you write here, then Execute runs your program on JDoodle’s servers.

Frequently asked questions
Is JDoodle’s online TypeScript compiler free?
Yes. JDoodle lets you write and run TypeScript without paying. A JDoodle account is only needed to save projects, use more AI credits, or unlock faster workspaces.
Do I need to install TypeScript to use JDoodle?
No. JDoodle runs TypeScript on its servers. Open this page in a browser and execute.
Which TypeScript version should I pick on JDoodle?
Choose the version that matches the course or codebase you are working against from the version menu. The builds JDoodle has installed are 5.2.2, and 5.9.3.
Can I add NPM libraries on JDoodle?
Yes, if the package is public. Private or local packages are not supported on this JDoodle page.
Can I run a multi-file TypeScript project online?
Not on this page, which runs a single TypeScript file. For several files in one project, open the JDoodle TypeScript IDE. Everything else works the same on both.
Is this an online TypeScript editor or a compiler?
Both. The page is an online TypeScript editor and it compiles and runs what you write.
Input, interactive runs, files, and the rest of the editor work the same on every language. See the JDoodle IDE documentation.
