    exported exported

    Getting Started

    1. Run npm install react-native-touchmap or yarn add react-native-touchmap to add this dependency to your project.
    2. Wrap your app's root component in the <Touchmap> tag.
    3. Export the output however you want!

    The <Touchmap> Component

    Below is a complete implementation.

    /** Reference variable within your component: */
    touchmap:Touchmap = null
    /** Inside render(): */
        ref={r => this.touchmap = r}
    That's it!


    Values Description
    style {}, [], # Style of the Touchmap container.
    debug true/false Display debugging features such as red border, version number, and 'View' and 'Clear' options?
    sessionOnly true/false Export touches for only the current session?
    ref Touchmap object Reference available functions raw, clear, and export from a property variable.
    children nodes Child nodes of the Touchmap. Usually the root component of the app.

    Ref Functions

    clear:()=>void Clears all touches from every session.

    raw:()=>Array<TouchSession> Returns a list of TouchSession objects, if you want to parse touches yourself.

    export()=>string Returns an encoded string of the image created. This may be used as a uri in an image component or can be handled as an image.

    Type Definitions

    /** Multiple touch events constituting a session of having the app running. */
    export interface TouchSession {
        /** Unique string identifier of the touch session. */
        id: string;
        /** Start time of this session. */
        startTime: Date;
        /** End time of this session. Optional because crashes might not register an end time. */
        endTime?: Date;
        /** An array of touches during this session. */
        touches: Array<TouchMeta>
        /** Size of the device. */
        deviceSize: DeviceSize;
    /** Single touch event object. */
    export interface TouchMeta {
        /** Coordinates of the touch. */
        coordinates: TouchCoordinates;
        /** Start time of this touch. */
        startTime: Date;
        /** End time of this session. Optional because touches may be canceled. */
        endTime?: Date;
        /** Duration of the touch, in milliseconds. */
        duration?: number;
    /** Simple coordinates interface. */
    export interface TouchCoordinates {
        /** x-coordinate of the touch. */
        x: number;
        /** y-coordinate of the touch. */
        y: number;
    /** Simple device size interface. */
    export interface DeviceSize {
        /** Width of the device, in pixels. */
        width: number;
        /** Height of the device, in pixels. */
        height: number;
