# app-config

A tool for generating configuration files for static apps.

### Install

```
yarn add @staticdeploy/app-config
```

### Quickstart

- add the following `<script>` to your `public/index.html`:

  ```html
  <script id="app-config" src="http://localhost:3456/app-config.js"></script>
  ```

- access the config variable in your code:
  ```js
  console.log(window.APP_CONFIG.MY_VAR);
  ```

Then:

#### In development

- define configuration in the `.env` file:

  ```sh
  APP_CONFIG_MY_VAR=my_val
  ```

- start the development server with `$(npm bin)/dev-config-server`

#### In production

- build your app and get the path of the app's `index.html` (for example, for
  apps built with
  [create-react-app](https://github.com/facebookincubator/create-react-app) the
  path is `build/index.html`)

- defining configuration via environment variables:

  ```sh
  export APP_CONFIG_MY_VAR=my_val
  ```

- inject the configuration into the index file by running:
  ```sh
  $(npm bin)/inject-config --file path/to/index.html
  ```

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.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.
