# Front end Utils

Repository containing javascript utility methods for string, date and regex based manipulation

## Getting Started

1.  Clone this repository and install its dependencies

```bash
$ git clone https://github.com/copartit/front-end-utils
$ cd front-end-utils
$ yarn install && yarn typed
```

`yarn typed` searches the libdef repo and download all the libdefs that are relevant for project and install them.

2.  Watch files and recompile whenever they change

```bash
$ yarn start
```

`yarn start` builds the library, then keeps rebuilding it whenever the source files change.

3.  Compile and bundle code

```bash
$ yarn build
```

`yarn build` builds the library to `dist`, generating three major files:

- `dist/frontendutils.cjs.js` a CommonJS bundle, suitable for use in Node.js, that requires the external dependency. This corresponds to the `"main"` field in package.json
- `dist/frontendutils.esm.js` an ES module bundle, suitable for use in other people's libraries and applications, that imports the external dependency. This corresponds to the `"module"` field in package.json
- `dist/frontendutils.umd.js` a UMD build, suitable for use in any environment (including the browser, as a <script> tag), that includes the external dependency. This corresponds to the `"browser"` field in package.json

4.  Check the code quality

```bash
$ yarn lint
```

`yarn lint` checks the code, whether it meets [Airbnb's JavaScript style guide](https://github.com/airbnb/javascript), and type checking using [Flow](https://github.com/facebook/flow).

5.  Run the unit tests

```bash
$ yarn test
```

`yarn test` runs the unit tests using [Jest](https://github.com/facebook/jest) to check if the function is executable.

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.
