Frequently Asked Questions
1Is my code saved anywhere?
Your projects are saved in your browser's local IndexedDB storage once you save or run them. Existing saved projects autosave after edits, and TSBin does not upload your code to an account.
2Do you have plugins?
Emmet support is available today for HTML and CSS editing. More editor helpers are planned.
3Do you have Markdown support?
Markdown support is coming soon. Today, TSBin supports HTML, CSS, JavaScript, TypeScript, and JSON project files.
4Can I keep working offline?
Yes. TSBin is designed around local-first browser storage, so saved projects can reopen without account setup or a server round trip.
5What file formats can I save or export?
TSBin supports HTML, CSS, JavaScript, TypeScript, and JSON project files. Export keeps those document formats in a zip file.
6Can I download my code?
Yes. Use File > Export Project to download the current workspace as a zip file.
7How can I clear the console?
Type clear() in the console and press Enter. The shorter clear command also clears the console.
8Does TSBin support dark mode and light mode?
Yes. Use the theme button or Settings to switch themes, or press ModShiftS to toggle between light and dark mode.
9Does TSBin support keyboard shortcuts?
Yes. Open the keyboard shortcuts dialog from the header or press Mod/ to see the available shortcuts.
10Do I have to create an account?
No. There is no account setup, and TSBin does not create an account for you automatically.
11How do I request features or report bugs?
Open the File menu and choose Send Feedback. The form supports bug reports, feature requests, and privacy requests.
12Does TSBin support Emmet for HTML and CSS?
Yes. Emmet support is available for HTML and CSS editing, which helps with common structures and selectors.
13Can I use this as an online HTML CSS editor?
Yes. TSBin gives HTML and CSS files a live browser preview, plus JavaScript and TypeScript when a page needs behavior.
