About TypeScript files
TypeScript is JavaScript with type annotations, compiled to JavaScript before it runs.
Open Online highlights .ts, .mts and .cts files. TSX files with JSX work too.
What you can do here
- Line numbers and syntax highlighting
- Search and replace
- Toggle word wrap
- Edit the text and save a copy
- See encoding, line endings, line and word counts
Limitations
- Very large files (over 50 MB) open read-only to keep the browser responsive.

Common questions
Does it type-check the code?
