Custom Component

Custom Component can be used to do create your own React component when the needed functionality isn't available in other components.

<img style={{ border:'0', marginBottom:'15px', borderRadius:'5px', boxShadow: '0px 1px 3px rgba(0, 0, 0, 0.2)' }} className="screenshot-full" src="/img/widgets/custom-component/custom-component-v2.png" alt="ToolJet - Widget Reference - Custom Component" />

Properties

Data

The data needs to be an objects which needs to be passed as data props to the Custom Component

Example:

{{{
    title: "Hi! There",
    buttonText: "Updated Text",
    queryName: "runjs1"
}}}

Code

This field is used to add a React code for your custom component. The packages for the custom component can be imported from Skypack or esm. For example, to import React package into the custom component it can be imported as import React from 'https://cdn.skypack.dev/react'.

Tooljet provides 3 props to interact with the app: data, updateData and runQuery.

• data is a shared object between custom component and Tooljet app.
• updateData is a function which accepts a single object used to update the data passed to the custom component.
• runQuery is a function which accepts a query name as a string used to run the query from the custom component.

Example:

import React from "https://cdn.skypack.dev/react";
import ReactDOM from "https://cdn.skypack.dev/react-dom";
import { Button, Container, Link } from "https://cdn.skypack.dev/@material-ui/core";

const MyCustomComponent = ({data, updateData, runQuery}) => (
    <Container>
        <h1>{data.title}</h1>
        <Button
            color="primary"
            variant="outlined"
            onClick={() => {updateData({...data, title: 'Hello World!!'})}}>
            {data.buttonText}
        </Button>
        <Button
            color="primary"
            variant="outlined"
            onClick={() => {runQuery(data.queryName)}}
        >
            Run Query
        </Button>
    </Container>
);

const ConnectedComponent = Tooljet.connectComponent(MyCustomComponent);

ReactDOM.render(<ConnectedComponent />, document.body);

:::info Tooljet.connectComponent acts as a HOC and it is required to get access to the data passed into the custom component and run the query :::
