# `@fluentui-react-native/framework-base`

This package provides core implementations and types to support both the legacy and current frameworks.

The functionality in these packages is now exposed as part of this package.

## Component Patterns

The shared patterns for rendering components, as well as the JSX handlers have been centralized in this package. More information can be found [here](./src/component-patterns/README.md).

## Type Helpers

This package provides several TypeScript utility types:

- `PropsOf<TComponent>` - Extract props from a React component type
- `FunctionComponent<TProps>` - A function component type without the children handling complications of React.FC
- `DirectComponent<TProps>` - A function component marked for direct rendering
- `PhasedComponent<TProps>` - A component with two-phase rendering support
- `SlotFn<TProps>` - Slot function type used in the composition framework
- `FinalRender<TProps>` - The final rendering signature for phased components

## JSX Runtime

This package exports a custom JSX runtime at `@fluentui-react-native/framework-base/jsx-runtime`. Use it in your component files with:

```tsx
/** @jsxImportSource @fluentui-react-native/framework-base */
```

The custom runtime enables automatic element flattening for direct and phased components.

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.

GitHub Actions: GitHub context variable exported as environment variable

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
