===Avoir la liste des versions d'un paquet===

  npm view paquet versions --json

===Mettre à jour les paquets dans package-lock.json===

Il parait que la commande ci-dessous fonctionne. Mais pas chez moi.

<code bash>
npm outdated
npm update -dd
npm install
</code>

===Mettre à jour les paquets dans package.json===

Installer le paquet ''npm-check-updates'' et exécuter la mise à jour.

Attention, cela force la dernière mise à jour sans vérifier la compatibilité entre les paquets.

<code bash>
npm i --location=global npm-check-updates
npm-check-updates -u
npm install
</code>

=====Erreurs=====

  * ''npm WARN read-shrinkwrap This version of npm is compatible with lockfileVersion@1, but package-lock.json was generated for lockfileVersion@2. I'll try to do my best with it!''

Lancer un ''npm install -g npm''
