# Build your first Polymer element

This repo goes with the [Build your first Polymer element tutorial](https://www.polymer-project.org/3.0/start/first-element/intro).

## Running the tutorial code

1.  Install pre-requisites for Polymer CLI (git, npm, Node.js). 

    [Full instructions are on the Polymer website.](https://www.polymer-project.org/3.0/docs/tools/polymer-cli).

2.  Install Polymer CLI:

        npm install -g polymer-cli@next

    [Full instructions are on the Polymer website.](https://www.polymer-project.org/3.0/docs/tools/polymer-cli).

3.  Clone this repo: 

        git clone https://github.com/PolymerLabs/polymer-3-first-element.git

4.  Change directory to the top-level project folder and install project dependencies:

        cd polymer-3-first-element
        npm install
        
5.  To preview your element, run the Polymer development server from the top-level project folder:

        polymer serve --open

## Next steps

Follow the [Build your first Polymer element tutorial](https://www.polymer-project.org/3.0/start/first-element/intro) to get started with Polymer.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.
