Comment utiliser node pour générer des documents Word ? L'article suivant vous expliquera comment utiliser Node pour générer des documents Word, partager une bibliothèque pratique et expliquer comment utiliser la bibliothèque. J'espère que cela sera utile à tout le monde !
Récemment, il existe un projet qui nécessite de générer des documents Word. Habituellement, ils sont générés via des modèles et les variables à l'intérieur sont remplacées par des espaces réservés. L'avantage est que c'est rapide, pratique, simple et qu'il existe. pas besoin d'ajuster le style des mots via le code. OK De nombreuses bibliothèques ne prennent pas en charge le dessin d'images (beaucoup d'entre elles sont des fonctions payantes). Après avoir cherché, j'ai trouvé une bibliothèque très intéressante qui répond juste à nos besoins. you
// https://docx.js.org/#/ npm i docx // https://www.npmjs.com/package/download npm i download
Explication, car le dessin docx ne prend en charge que le streaming de fichiers, vous devez donc télécharger les fichiers réseau localement et les convertir en tampons
Pas grand chose à dire, parlons du code
