Designing with data helps build a connection to the people who use your product every day. Let’s walk through how to make that possible.

Props

If you’re just getting started with React, one of the key concepts to grasp are props. A prop is short for property, and works just like the right-hand properties panel you’re used to adjusting in Framer X. In design tools, we can modify the background color with a color picker, the opacity with a slider, and the radius with an input. In React, we can “pass in” props to modify just as easily.

Visualizing props

Building React components is a lot like design components created in the canvas. After creation,Framer automatically recognizes elements you may want to change. In the design component below, the avatar, name, and message can be changed.

When working with code components, things start to look familiar…

<Message
  Avatar={"./images/Headshot.jpg"}
  Message={"Hey everyone!"}
/>

As you can see, using data in our prototypes is as simple as passing in props. You can learn more about props in this article from Koen Bok. Here are a few ways to get started working with data in Framer X.

Randomized Data

One of the easiest ways to start playing with data is to create your own. Like all designers, you probably have a list of go-to placeholders. Using randomized data is great way to give your prototype a fresh look on each reload. All it takes is a simple function that accepts an array, then randomly returns one of the values.

function random(list: Array<any>) {
    return list[Math.floor(Math.random() * list.length)]
}
 
const names = ['Johnny Appleseed', 'Sarah Brown', 'Koen Bok', ...]
 
console.log(random(names)) //Koen Bok
console.log(random(names)) //Johnny Appleseed
console.log(random(names)) //Sarah Brown

Plugging that into our React component would look something like this:

<Message
  Avatar={random(images)}
  Name={random(names)}
  Message={random(messages)}
/>

JSON

Chances are there’s JSON data lying around that you can use within your designs. This method helps reflect real use cases and demonstrate what the product actually looks like. This also works as a great way to quickly edit what’s displayed because the file is editable.

import * as data from "./Test.json"
import { Message } from "./Message"
 
export function ChatFeed() { 
  let messages = data.map((item) => (
      <Message name={item.name} text={item.text} image={item.image} />
  ))
 
  return (
    <Frame>
      {messages}
    </Frame>
  )
}

First, we’ll need to import our JSON data. Shown on line 1, we can import * as data, which is short for import “everything” as data from the file. You could choose any name, but I went with data to help keep track of what I'm handling within the component.

Next, we’re going to make use of the map function, which is a lot like a forEach loop—only better. The map function is a declarative way to loop over each item in an array, and in this case, each piece of data in our JSON. It creates a new array for us (as React doesn’t allow mutating), which we can assign to a variable called messages that will be used in the return function.

APIs

Taking things a step further, we can grab data directly from the source. We can use APIs that return data for us, typically in the form of JSON.

What’s an API?

Don’t worry, I didn’t know much about them either before using Framer X. You might compare them to ordering food at a restaurant. Just like you order what you’d like from the menu, using an API is a way to order things. We’ve been using a chat message component so far, so something we might want to order from an API are avatar images. For this example, tinyfac.es delivers those images to you.

export function Avatar() {
    const [image, setImage] = React.useState("")
 
    React.useEffect(() => {
        const url = `https://tinyfac.es/api/users`
        fetch(url)
            .then(response => response.json())
            .then(data => setImage(data[0]["avatars"][3]["url"]))
    }, [])
 
    return (
        <Frame
            image={`url(${image})`}
        />
    )
}

For this one, we’re using both the useState and useEffect hook. If you aren’t too familiar with these, Zach Johnston gives a great overview in this Framer blog post.

After we define our URL (https://tinyfac.es/api/users), we can “fetch” the data from the API, then wait for the data to be served, then set our image state using that same data. That’s all it takes to get started using an API within your components.

Database (Firebase)

So many of our products have a collaboration aspect that it can be difficult to simulate what a “real” experience would be like. Firebase can do just that, giving prototypes the power to talk to one another.

Getting Started

Setup in Firebase

1. Head over to https://firebase.google.com and create a project.
2. Go to Settings → Project Settings. In the General tab, look for “Your apps”, and select Web from the options of iOS, Android, Web, and Unity.
3. Give your app a nickname and check the box that reads: “Also set up Firebase Hosting for this app.”
4. Skip the rest—you’re all set up.
5. Returning to Settings, scroll down to “Your apps” and select the Config option. You’ll be needing this in a bit.
6. On the left panel within the Develop section, click Database → Create Database. Choose “Start in test mode”.
7. Use the dropdown to go to Realtime Database, then go to rules and change both read and write to true.

Setup in Framer X

1. Create a new Framer X file and name it FirebaseFramerX.
2. With the file opened, go to File → Show Project Folder.
3. Open Terminal and enter ~ \$ cd FirebaseFramerX.framerx.
4. Next, enter npm install firebase.
5. Create a new code component and name it ChatFeed.
6. Copy and paste the snippet below, replacing firebaseConfig with your own from step 5 in the section above.

import * as React from "react"
import { Frame, Stack } from "framer"
import * as firebase from "firebase"
 
let database
const firebaseConfig = {
    apiKey: "YOUR_API_KEY",
    authDomain: "project-name.firebaseapp.com",
    databaseURL: "https://project-name.firebaseio.com",
    projectId: "project-name",
    storageBucket: "",
    messagingSenderId: "xxxxxxxxxxxx",
    appId: "x:xxxxxxxxxxxx:web:xxxxxxxxxxx",
}
 
const LoadFirebase = () => {
    if (!firebase.apps.length) {
        firebase.initializeApp(firebaseConfig)
    }
    database = firebase.database()
}
 
export function ChatFeed() {
    LoadFirebase()
     
    const [messages, setMessages] = React.useState([])
     
    React.useEffect(() => {
        let firebaseDatabase = firebase.database().ref("messages/")
        firebaseDatabase.on("value", snapshot => {
            let newMessages = []
            snapshot.forEach(child => {
                const message = child.val()
                newMessages.push(
                    <Message
                        key={child.key}
                        name={message.name}
                        text={message.text}
                    />
                )
            })
            setMessages(newMessages)
        })
    }, [])
 
    const writeMessageToFirebase = value => {
        firebase
            .database()
            .ref("messages/")
            .push({
                text: value,
                name: "Max",
            })
    }
 
    return (
        <Stack size={"100%"}>
            <Frame onTap={() => writeMessageToFirebase("Hello")}>
                Send Message
            </Frame>
            {messages}
        </Stack>
    )
}
 
function Message(props) {
    return (
        <div>
            <div>{props.name}</div>
            <div>{props.text}</div>
        </div>
    )
}

Breaking this down, there are 3 main concepts to grasp.

Setup (lines 1-24): Getting hooked up to our database.

Listening for changes (lines 26-44): Once a message gets sent, our component will re-render with the updated state of the database.

Pushing changes (lines 46-54): The writeMessageToFirebase function allows us to send messages to the database that will be reflected in all prototypes.
