Online TypeScript Editor
Write and share TypeScript in the browser and collaborate on it in real time.
ShareCode is a browser-based TypeScript editor with syntax highlighting, an instant shareable link, and live multi-user editing. It's the fastest way to put a typed example in front of someone — a generic, a discriminated union, a piece of tricky inference — without spinning up a project and waiting for the language server to warm up.
Write or paste your TypeScript, share the URL, and edit together in real time. When you're trying to explain why a type does or doesn't compile the way someone expects, doing it on shared code beats describing it in words.
ShareCode focuses on collaborative editing and sharing; it doesn't type-check or transpile your code. So it's at its best where the value is in reading and writing the types together — explaining, reviewing, interviewing — rather than compiling them, which you'd still do in your editor or CI.
Why use an online TypeScript editor?
TypeScript's tooling is excellent but not lightweight to share. Getting someone else to see exactly what you see usually means they clone a repo, install dependencies, and let the type-checker index. For a single example that's far too much ceremony. A browser editor lets you hand over a link that opens the precise code in seconds.
Because the space is collaborative, it's a teaching surface as much as a sharing one. You can adjust a generic constraint, narrow a union, or annotate a parameter while the other person watches the change land — the kind of "try it and see" that makes type concepts click far better than a paragraph of explanation.
Real-time collaboration
Work through a typed example together with live cursors and instant synchronization.
TypeScript highlighting
Type annotations, generics, and interfaces stay readable while you write or review.
Instant shareable link
Share the code space URL and collaborators join immediately — no account needed.
How to use the TypeScript editor
Open a code space
Spin up a fresh space at its own URL in one click — no project, no install, no account.
Write or paste TypeScript
Add your types or code and choose TypeScript from the language menu for matching highlighting.
Share the link
Send the URL to whoever needs to see the example; they open the same code immediately.
Refine the types together
Edit live — tweak a generic, narrow a union, annotate a parameter — and watch the change on both screens.
A TypeScript starting point
function greet(name: string): string {
return `Hello, ${name}!`;
}
console.log(greet("world"));What it's great for
Explaining a type to a teammate
Share the exact generic or union you're discussing and edit it live. Showing why the inference behaves a certain way is far clearer than describing it in a thread.
Interviews with typed code
Have a candidate write TypeScript and reason about its types while you watch. A shared link with zero setup keeps the focus on their thinking.
Reviewing an interface or generic
Paste the type under review and suggest changes in place. The other person sees and can adjust it immediately.
Sharing a typed snippet quickly
Skip the repo and the install — drop the code in a space and send the link so the recipient can read and edit it.
Frequently asked questions
Does it type-check my code?
No — ShareCode is a collaborative editor that highlights and shares TypeScript, but does not compile or type-check it. In-browser execution is available for JavaScript only.
Can I paste in a large file?
Yes. Paste your TypeScript, share the link, and collaborators can read and edit it with you in real time.
Do collaborators need an account?
No. Anyone with the link opens the space and edits immediately — there's no sign-up to join.
Is it free?
Yes, creating and sharing code spaces is free, with no per-collaborator charge.
