Whether you're pulling data from databases, third-party APIs, or other sources, Retool ensures your custom components have the data they need to function correctly. This integration capability is essential for keeping your visualizations up-to-date with the latest information.
Now that your components are integrated, it's crucial to understand how to pass data to them effectively.
Passing Data to Custom Components
Passing data to custom components can be done in several ways. One common method is using iframes to embed components or using a custom component to define the model, IFrame code and interactions. Each method has its advantages, depending on the complexity and needs of your application. Choosing the right method is crucial for ensuring smooth and efficient data flow.
Methods for Data Passing
1. Using iframes for Data Passing
Features:
Versatility and Isolation: Using iframes is a versatile approach, especially when dealing with external content or isolated environments. An iframe provides a sandboxed environment, meaning the embedded content runs independently of the parent Retool application.
Embedding External Content: By embedding an iframe in your Retool application, you can load external web content or applications within a defined area of your interface. This method is useful for displaying content from third-party services or integrating web applications developed independently from your main app.
Example Script:html<iframe srcdoc="<html>
<body>
<script src='https://cdn.plot.ly/plotly-latest.min.js'></script>
<div id='chart'></div>
<script>
var data = [{ x: [1, 2, 3, 4], y: [10, 15, 13, 17], type: 'scatter' }];
Plotly.newPlot('chart', data);
</script>
</body>
</html>"></iframe>
In this example, the iframe's srcdoc attribute is used to embed an HTML document directly within the iframe, which includes a script to load Plot.ly and create a scatter plot.
2. Using Custom Components to Define the Model, IFrame Code and Interactions.
Features:
React or HTML/JavaScript Support: Build components using React or plain HTML and JavaScript. It also supports custom styling options.
Data Passing: Ability to pass data to and from the Retool app.
Configurable Permission and Settings: Can be granted permissions for popups, link redirection, camera, downloads, form submissions, fullscreen, geolocation, microphone, modals, and more..
Event Handling: Supports custom event handlers to trigger actions or queries.
Example Script:import React, { useEffect, useRef } from 'react';
const SimplePlotlyScatter = () => {
const chartRef = useRef(null);
const [data, setData] = Retool.useStateObject({
name: "data",
initialValue: { x: [1, 2, 3, 4], y: [10, 15, 13, 17] },
label: "Chart Data",
});
useEffect(() => {
if (window.Plotly) {
updateChart();
} else {
loadPlotly();
}
}, [data]);
const loadPlotly = () => {
const script = document.createElement('script');
script.src = "https://cdn.plot.ly/plotly-latest.min.js";
script.onload = updateChart;
document.head.appendChild(script);
};
const updateChart = () => {
window.Plotly.newPlot(chartRef.current, [{
x: data.x,
y: data.y,
type: 'scatter',
mode: 'lines+markers',
}]);
};
return <div ref={chartRef} style={{ width: '100%', height: '300px' }} />;
};
export default SimplePlotlyScatter;
Data Flow in Custom Components
By leveraging the following methods, you can create dynamic, interactive Custom Components that integrate seamlessly with your Retool applications, allowing for bi-directional data flow between your custom UI and the rest of your app's logic and components
Accessing Model Inputs
Custom Components in Retool use special hooks to define inputs that can be configured in the Retool Inspector. These hooks are part of the Retool object and come in different types for various data:
Retool.useStateString(): For text inputs
Retool.useStateNumber(): For numeric inputs
Retool.useStateBoolean(): For boolean (checkbox) inputs
Retool.useStateObject(): For complex object inputs
Retool.useStateArray(): For array inputs
Example Script
const [threshold, setThreshold] = Retool.useStateNumber({
name: "threshold",
initialValue: 10,
label: "Count Threshold",
description: "Set the threshold for the count alert",
});
This creates a "threshold" input that can be set in the Retool Inspector.
The values returned by these hooks can be used directly in your component<p>Current Threshold: {threshold}</p>
Sending Data from Custom Component to App
To make data from your custom component available to the rest of your Retool app, use the Retool.updateModel() method
useEffect(() => {
Retool.updateModel({ currentCount: count });
}, [count]);
This updates the currentCount value in the model whenever the count state changes
In your Retool app, you can access these values using the syntax: For example, {{InteractiveCounter.model.currentCount}} would give you the current count.
Creating and Triggering Events
Defining Event Callbacks
Use Retool.useEventCallback to create events that can trigger actions in your Retool app
const incrementEvent = Retool.useEventCallback({ name: "increment" });
Triggering Events
You can then call this event in your component:
incrementEvent();
Handline Events in Retool
In your Retool app, you can add an event handler for this "increment" event to perform actions when it's triggered
Triggering queries from your custom components can significantly enhance their functionality. This allows your components to fetch fresh data, update visualizations, or perform actions based on user interactions. Efficient query triggering is essential for creating responsive and dynamic applications.
For more sophisticated visualizations, integrating popular charting libraries can elevate your custom components.
