TypeScript Paste

TypeScript is the language where the interesting part is usually the types, and the types are exactly what chat apps destroy. Drop a conditional type, a mapped type, or a discriminated union into Slack and the angle brackets collapse, the indentation flattens, and the person you're asking for help now sees a wall of monospace soup. files.link gives you a paste link that renders TypeScript through highlight.js with the structure intact — generic parameters, as const assertions, decorators, enum bodies, and template literal types all keep their shape and color.

This is the angle that separates a TypeScript paste from a plain JS one: you're frequently sharing the type-level machinery, not the runtime logic. A type DeepPartial<T> that recurses, a builder whose return type narrows step by step, an inferred return that VS Code shows you but you can't easily copy into a message — those read clearly on a paste page and badly everywhere else.

For TSX, choose the TypeScript language and highlight.js handles the JSX embedded in your components correctly; if a gnarly generic-heavy line confuses it, fall back to plain text and you still get faithful, copy-safe formatting.

No account is needed to create or read a paste, so a teammate or a Stack Overflow answerer opens the link with zero friction. Anonymous pastes hold 100KB and expire automatically after 24 hours — long enough to debug a type error, short enough that throwaway snippets don't pile up. Sign in and you get 1MB pastes and your choice of expiry, from one hour up to permanent, which matters when you want a stable URL for a code-review comment or a documented example that should still resolve months later.

Unlike a GitHub Gist, there's no signup wall to publish and no account history accumulating snippets you'll never revisit. Unlike a Slack code block, the link works for anyone outside your workspace and survives the scrollback. Paste, pick TypeScript, copy the URL — the receiver sees exactly the types you meant to send.
