ReactComponent

Defined in: parser/types.ts:1506

The ReactComponent interface is used to define the properties of a react component. This component is used to render react code with certain parameters. These parameters can be used within your react code to render different things.

Unlike other types of components, the path for a React component is relative to the src/public/ folder. Similar to our standard assets, we suggest creating a folder named src/public/{studyName}/assets to house all of the React component assets for a particular study. Your React component which you link to in the path must be default exported from its file.

React components created this way have a generic prop type passed to the component on render, <StimulusParams<T>>, which has the following types.

{
  parameters: T;
  useTrrack: (options: ConfigureTrrackOptions) => Trrack;
  setAnswer: ({ status, answers }: { status: boolean, answers: Record<string, any> }) => void
}

parameters is the same object passed in from the ReactComponent type below, allowing you to pass options in from the config to your component. setAnswer is a callback function allowing the creator of the ReactComponent to programmatically set the answer. This can be useful if you don't use the default answer interface, and instead have something more unique. Call the useTrrack function supplied in StimulusParams when the component needs provenance. It creates the Trrack instance and reports apply, undo, redo, and other traversals automatically.

So, for example, if I had the following ReactComponent in my config:

{
  "type": "react-component",
  "path": "my_study/CoolComponent.tsx",
  "parameters": {
    "name": "Zach",
    "age": 26
  }
}

My react component, CoolComponent.tsx, would exist in src/public/my_study/assets, and look something like this:

export default function CoolComponent({ parameters, setAnswer, useTrrack }: StimulusParams<{name: string, age: number}>) {
  // render something
}

Properties

Property	Type	Description	Inherited from	Defined in
allowFailedTraining?	boolean	Allow continuing with incorrect answers after attempts are exhausted. Overrides uiConfig.allowFailedTraining. Defaults to true.	BaseIndividualComponent.allowFailedTraining	parser/types.ts:1419

nextButtonAutoAdvanceWarningMessage?	string	The warning message shown before auto-advance. Include {seconds} to interpolate the remaining number and {unit} to interpolate second/seconds.	BaseIndividualComponent.nextButtonAutoAdvanceWarningMessage	parser/types.ts:1407
nextButtonAutoAdvanceWarningTime?	number	The time in milliseconds before auto-advance when the warning message is shown. Defaults to 30000.	BaseIndividualComponent.nextButtonAutoAdvanceWarningTime	parser/types.ts:1405
