Code:

// I'll be missing after tsc 😭

/**
 * I'll be here after tsc 😎
 */

export const api = () => { /* some code ... */ } 

Expected behavior:

Keeping both block and inline comments in declaration files in both transpiled files and declaration files

Actual behavior:

Inline comments are removed in declaration files

And correctly kept within transpiled files

Commencez par reproduire le problème avec la tsconfig fournie et l’exemple TypeScript, en utilisant TypeScript 3.1.3 ou typescript@next. Comparez les fichiers de déclaration générés avec les fichiers transpilés ; le travail est terminé lorsque les commentaires inline sont conservés dans la sortie des déclarations aux côtés des commentaires de bloc.
