Stop Reformatting Your Posts by Hand
Pasting your articles directly into Medium often strips your code indentation and ruins your formatting. Poneglyph guarantees that what you wrote is exactly what your readers see.
// TypeScript Function
export function loadData<T, R>(key: string) {
// Indentation flattened to 1 space!
const item = cache.get(key);
return item;
}
Code brackets <T, R> disappear or break
Multi-space indentation flattened
Original canonical backlink forgotten// Cleanly injected into your draft
export function loadData<T, R>(key: string): Promise<R> {
const item = await cache.get(key);
return item as R;
}
Code brackets <T, R> stay 100% intact
