There are three ways to get started with the Jovo Framework. You can either install our command line tools (recommended), save the jovo-framework npm package, or clone our sample voice app.
Technical Requirements: Node.js version 4 or later & NPM (node package manager). Here are some tutorials to install Node.js and NPM: Mac, Windows.
The Jovo Command Line Tools offer an easy way to create new voice apps from templates. Install them with:
$ npm install -g jovo-cliYou can create a Jovo project into a new directory with the following command:
$ jovo new <directory>This will clone the Jovo Sample App and install all the necessary dependencies so you can get started right away.
If you want to use the Jovo Framework as a dependency in an already existing project, you can also use npm to save it to your package.json:
$ npm install --save jovo-framework
Right now, there is one sample app available, which you can find here.
You can clone it like this:
$ git clone https://github.com/jovotech/jovo-sample-voice-app-nodejs.git
Afterwards, go to the app directory and do
$ npm install

We still consider this a beta-version of the Jovo framework: We give it our all to make it as complete as possible (and it supports most of the Alexa and Google Assistant functions), but there are certain features that are currently in development.
What we're currently working on:
- Adding more DB integrations
- Extending the User class
Jovo is a free, open source framework for voice developers. We're improving it every day and appreciate any feedback. How to support us? Just go ahead and build something cool with the framework and let us know at feedback@jovo.tech. Thanks!
