NodeJS and NodeJS frameworks

Node developers can jump into creating Fonoster apps quickly by the help of the docs, using the CLI tool and the NodeSDK.

Fonoster NodeSDK works well with many JavaScript frameworks as React, Vue, React Native, Angular and Blaze.

If you want to use it for a browser-based app you can either install it from NPM or using the WebSDK for Browserify or Webpack. However, for a simple HTML app, you can direcly use the WebSDK via CDN.
