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;
setAnswer: ({ status, provenanceGraph, answers }: { status: boolean, provenanceGraph?: TrrackedProvenance, 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, as well as the provenance graph. This can be useful if you don't use the default answer interface, and instead have something more unique.

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 }: StimulusParams<{name: string, age: number}>) {
// render something
