The Value List Filter operator is a WireCloud operator that provides a simple mechanim of converting list of objects, produced by an output endpoint, into a list of values. This is done by filtering the JSON data contained in the array using the path configured through a preference using a dot-sepparated sytanx.

Be sure to have installed Node.js in your system. For example, you can install it on Ubuntu and Debian running the following commands:

sudo apt update; sudo apt install curl gnupg
curl -sL https://deb.nodesource.com/setup_8.x | sudo bash -
sudo apt install nodejs npm

You also have to install the Grunt's command line interface (CLI):

sudo npm install -g grunt-cli

The remaining dependencies are installed using npm (you have to run this command inside the folder where you downloaded this repository):

npm install

Once installed all the build dependencies you can build this operator by using grunt:

grunt

If everything goes well, you will find a wgt file in the dist folder.

Documentation about how to use this operator is available on the User Guide. Anyway, you can find general information about how to use operators on the WireCloud's User Guide available on Read the Docs.
