Have you ever faced the challenge of keeping your design and development teams in sync? As a front-end developer, would you like to automate the task of keeping designs updated? so that when you make changes in Figma, they will immediately appear in your code.

By the end of this article, you will understand the value of real-time collaboration. You will also learn about the tools and tech that enable it and get steps to use it in your projects.

Understanding Real-Time Collaboration

Real-time collaboration is when team members interact at the same time. It allows for instant updates and feedback. Figma design updates to sync with code. Likewise, changes to the code also appear in Figma.

Benefits of Real-Time Collaboration in Web Development

Real-Time collaboration offers these benefits:

Consistency: Consistency keeps the design and code in sync, prevents differences, and maintains a unified vision.
Efficiency: It saves time by reducing updates and corrections, allowing teams to focus on more important tasks.
Collaboration: This improves how designers and developers communicate and work together, making the work environment more united and productive.
Speed: It speeds up development. It allows quick iterations and instant feedback, leading to faster project completion.

Key Tools and Technologies that Facilitate Real-Time Collaboration

To achieve real-time collaboration, several tools and technologies can be used:

Figma: This is a design tool. Designers create and manage UI designs together through this tool. Figma has real-time collaboration. Multiple team members collaborate on a single design.
Figma API: This provides access to Figma files. It lets developers fetch and change design data. This API is crucial for integrating Figma with front-end code.
Git: A version control system that helps manage code changes.
Node.js: A JavaScript runtime. It can set up polls and fetch design updates from Figma.
React: A JavaScript library for building user interfaces. React's component-based architecture makes updating the UI for design changes easy.
Axios: It uses promises to make requests to APIs over HTTP. With it, users can fetch design data from Figma and update the front-end code.
Styled-Components: A library for styling React components. Styled-components allow for dynamic styling based on design data.

Setting Up Your Development Environment

You need to set up a development environment to connect Figma designs and live code in real time. It needs the following tools and libraries:

Install Node.js: Download and install Node.js.
Create a Figma Account: Sign up for a Figma account if you do not have one.
Create a React Application: Use create-react-app to set up a new React project.

npx create-react-app my-app
cd my-app

Install Required Libraries on your Code Terminals: Install Axios, Styled-Components, and Nodemon

npm install axios styled-components nodemon

Generate a Figma API Token: Go to Figma account settings and generate a personal access token.
Fetch Design Data from Figma: Create a script using the Figma API to fetch design data.
Set Up Nodemon for Automatic Restarts

"scripts": {
  "start:watch": "nodemon --watch src/buttonDesign.json --exec 'npm start'"
}

This setup helps keep real-time sync and ensures that the latest design updates always appear in your running app.

Integrating Figma with Front-end Code

Integrating Figma with your front-end codebase allows for real-time sync. Design changes are immediately reflected in the app.

Using Figma’s API to Fetch Design Updates

This Figma API accesses and changes Figma files. It integrates design changes into the codebase.

import fetch from "node-fetch";

const FIGMA_API_URL = "https://api.figma.com/v1/files/";
const FILE_ID = "your-file-id"; // File ID
const API_TOKEN = "your-api-token"; // API token generated

async function fetchDesignData() {
  const response = await fetch(`${FIGMA_API_URL}${FILE_ID}`, {
    headers: {
      "X-Figma-Token": API_TOKEN,
 },
 });

  if (!response.ok) {
    throw new Error(`Error fetching design data: ${response.statusText}`);
 }

  const data = await response.json();
  return data;
}

This code imports the node-fetch library to make HTTP requests. It also defines constants for theFigma API URL, FILE_ID, and API token. The fetchDesignData function sends a GET request to the Figma API. It includes the API token in the headers for authentication. If the request is successful, it parses the response as JSON and returns the design data. If the request fails, it throws an error with the response.statusText.

Setting Up a Polling Mechanism

We will set up a polling mechanism to check for updates in the Figma design. Polling means making regular API requests at set times to get the latest design data.

function startPolling(interval) {
  setInterval(async () => {
    try {
      const data = await fetchDesignData();
      console.log("Fetched design data:", data);
 } catch (error) {
      console.error("Error fetching design data:", error);
 }
 }, interval);
}

// Start polling every 5 minutes (300000 milliseconds)
startPolling(300000);

This code sets up a polling mechanism to fetch design data from Figma at regular intervals. startPolling uses setInterval to call fetchDesignData at a set time. In this case, it is every 5 minutes or 300,000 milliseconds. If the data is fetched, it logs it to the console. If an error occurs, it logs the error message.

Automating the Update Process in Your Front-end Codebase

After you fetch the design data, you need to process it. Then, update the front-end components. You can automate this task. It reflects design changes made in Figma in the app. It does this without needing manual work.

import React, { useState, useEffect } from "react";
import axios from "axios";
import styled from "styled-components";

const Button = styled.button`
 width: 194px;
 height: 42px;
`;

const App = () => {
  const [designData, setDesignData] = useState(null);

  useEffect(() => {
    const fetchData = async () => {
      try {
        const response = await axios.get("/designData.json");

        setDesignData(response.data);
 } catch (error) {
        console.error("Error fetching design data:", error);
 }
 };

    fetchData();
 }, []);

  if (!designData) {
    return <div>Loading...</div>;
 }

  return (
    <div>
      <Button backgroundColor={designData.backgroundColor}>Sign up</Button>
    </div>
 );
};

export default App;

This code snippet shows how to automate updates in your front-end code. It brings in the needed libraries: React, axios, and styled-components. It also defines a styled.button component. The App component gets design data from a local JSON file (designData.json) using axios. Then, it updates the state with this data. The useEffect hook fetches the data when the component mounts.

Implementing Real-Time Sync

This process is important for maintaining consistency and efficiency in web projects. It also allows designers and developers to work well together.

import fetch from "node-fetch";
import fs from "fs";
import path from "path";

const FIGMA_API_URL = "https://api.figma.com/v1/files/";
const FILE_ID = "your-file-id"; // Replace with your actual file ID
const API_TOKEN = "your-api-token"; // Replace with your actual API token
const NODE_ID = "your-node-id"; // Replace with your actual node ID

async function fetchDesignData() {
  const response = await fetch(`${FIGMA_API_URL}${FILE_ID}`, {
    headers: {
      "X-Figma-Token": API_TOKEN,
 },
 });

  if (!response.ok) {
    throw new Error(`Error fetching design data: ${response.statusText}`);
 }

  const data = await response.json();
  return data;
}

function startPolling(interval) {
  setInterval(async () => {
    try {
      const data = await fetchDesignData();

      function findNodeById(node, id) {
        if (node.id === id) {
          return node;
 }
        if (node.children) {
          for (const child of node.children) {
            const foundNode = findNodeById(child, id);
            if (foundNode) {
              return foundNode;
 }
 }
 }
        return null;
 }

      const component = findNodeById(data.document, NODE_ID);

      if (component) {
        const designData = {
          // Extract relevant design data from the component
 };

        const filePath = path.resolve("src/designData.json");
        fs.writeFileSync(filePath, JSON.stringify(designData, null, 2));

        console.log("Design data saved to src/designData.json");
 } else {
        console.log("Component not found");
 }
 } catch (error) {
      console.error("Error fetching design data:", error);
 }
 }, interval);
}

startPolling(300000); // Poll every 5 minutes

Important libraries are imported with (node-fetch, fs, and path). It also sets constants for the Figma API URL, FILE_ID, API token, and NODE_ID. The fetchDesignData function sends a GET request to the Figma API. It does this to retrieve design data.

Creating a Script to Pull Design Changes from Figma

To enable real-time sync, we update the code. It pulls the latest design changes from Figma. This script will get the design data and save it in a local JSON file. Then, the front-end can use the file.

import fetch from "node-fetch";
import fs from "fs";
import path from "path";

const FIGMA_API_URL = "https://api.figma.com/v1/files/";
const FILE_ID = "your-file-id"; // File ID
const API_TOKEN = "your-api-token"; // API token created

async function fetchDesignData() {
  const response = await fetch(`${FIGMA_API_URL}${FILE_ID}`, {
    headers: {
      "X-Figma-Token": API_TOKEN,
 },
 });

  if (!response.ok) {
    throw new Error(`Error fetching design data: ${response.statusText}`);
 }

  const data = await response.json();
  return data;
}

function startPolling(interval) {
  setInterval(async () => {
    try {
      const data = await fetchDesignData();

      const component = findFileID(data.document, FILE_ID);

      if (component) {
        const designData = {
          // Extract relevant design data from the component
 };

        const filePath = path.resolve("src/designData.json");
        fs.writeFileSync(filePath, JSON.stringify(designData, null, 2));

        console.log("Design data saved to src/designData.json");
 } else {
        console.log("Component not found");
 }
 } catch (error) {
      console.error("Error fetching design data:", error);
 }
 }, interval);
}

startPolling(300000); // Poll every 3 minutes

The code above extracts key design properties and saves them to a local JSON file (designData.json). This ensures that the front-end code is often updated and gets the latest design changes from Figma.The startPolling function sets up a polling mechanism. It calls fetchDesignData every 5 minutes and processes the fetched data.

Updating Front-end Components Based on Design Changes

Once the design data is saved to a local JSON file, it is updated automatically in our front-end components to reflect these changes when we run the application.

Case Study: Real-Time Collaboration in Action

In this case study, we will walk through an example project. It demonstrates real-time syncing between Figma and a React app.

This will include setting up the environment, fetching design data, and polling for updates. Then, it will involve updating front-end components based on design changes.

Project Overview

We will create a simple React application that syncs with a Figma design file in real time. The application shows a button with a design property (background color) pulled from Figma.

Step-by-Step Implementation

Setting Up Figma: Create a new Figma file and design a button.

When you click the button shape, take note of the FILE_ID and NODE_ID from the URL. The URL in the image above shows the FILE_ID as o6BBmg4KBaX38TA2QmL3jX. The NODE_ID is 24:2. Also, navigate to the account's settings and create an API Token.

Fetching Design Data: Create a script to fetch design data from Figma using its API. Save this script as fetchDesignData.mjs. The .mjs extension is used for ES modules, while .js is more universally accepted and can be used with both CommonJS and ES module syntax. The script below creates a polling system. It gets the latest design data from Figma every 5 minutes. It puts the new data into the buttonDesign.json file.

import fetch from "node-fetch";
import fs from "fs";
import path from "path";

const FIGMA_API_URL = "https://api.figma.com/v1/files/";
const FILE_ID = "o6BBmg4KBaX38TA2QmL3jX"; // The file ID from the URL
const API_TOKEN = "figd_42Ty36XSqr6w05u_YYfAU_9xU5n6m0QZ0wCZEyDI"; // API token created
const NODE_ID = "24:2"; // Node ID from the URL

async function fetchDesignData() {
  const response = await fetch(`${FIGMA_API_URL}${FILE_ID}`, {
    headers: {
      "X-Figma-Token": API_TOKEN,
 },
 });
  if (!response.ok) {
    throw new Error(`Error fetching design data: ${response.statusText}`);
 }
  const data = await response.json();
  return data;
}

function startPolling(interval) {
  setInterval(async () => {
    try {
      const data = await fetchDesignData();

      function findNodeById(node, id) {
        if (node.id === id) {
          return node;
 }
        if (node.children) {
          for (const child of node.children) {
            const foundNode = findNodeById(child, id);
            if (foundNode) {
              return foundNode;
 }
 }
 }
        return null;
 }

      const buttonComponent = findNodeById(data.document, NODE_ID);

      if (buttonComponent) {
        const backgroundColor = buttonComponent.fills[0].color;
        const rgbaColor = `rgba(${backgroundColor.r * 255}, ${
          backgroundColor.g * 255
        }, ${backgroundColor.b * 255}, ${backgroundColor.a})`;

        const designData = {
          backgroundColor: rgbaColor,
 };

        const filePath = path.resolve("../src/buttonDesign.json");
        fs.writeFileSync(filePath, JSON.stringify(designData, null, 2));

        console.log("Design data saved to src/buttonDesign.json");
 } else {
        console.log("Button component not found");
 }
 } catch (error) {
      console.error("Error fetching design data:", error);
 }
 }, interval);
}

// Start polling every 5 minutes (300000 milliseconds)
startPolling(300000);

Updating Front-end Components: Create a React component in App.js to use the design data. The Button component uses styled-components. It sets its background color based on the design data. The App component fetches the design data from buttonDesign.json. It updates the state with the latest design data. The useEffect code ensures that the data is being retrieved. Run the React app. Changes in the Figma design update the buttonDesign.json. This update happens on the website every 5 minutes.

import React, { useState, useEffect } from "react";
import styled from "styled-components";
import axios from "axios";
import designData from "./buttonDesign.json"; // Adjust the path if necessary

const App = () => {
  // Remove the fetchDesignData function and use the imported designData directly
  const [data, setData] = useState(null);

  useEffect(() => {
    setData(designData);
 }, []);

  const Button = styled.div`
 width: 194px;
 height: 42px;
 background-color: ${data ? data.backgroundColor : "#c4c4c4"};
 display: flex;
 justify-content: center;
 align-items: center;
 border-radius: 30px;
 color: #fff;
 cursor: pointer;
 &:hover {
 background: #0000ff;
 box-shadow: -4px 0px 4px rgba(183.6, 207.4, 255, 0.25) inset;
 }
 `;

  return (
    <div>
      <Button>Sign up</Button>
    </div>
 );
};

export default App;

JSON Data from Figma: The program stores the fetched design data in the buttonDesign.json file. This JSON data has the design component's backgroundColor property. We will use it to update the front-end components. Saving data locally lets the app show changes from Figma in the code.

Browser Output: The browser output shows changes made in the Figma design.

These methods show design changes made in Figma in the front-end code.

Challenges Faced and Solutions Implemented

We added real-time syncing between Figma and the React app during the process. But, we faced several challenges.

Fetching and Parsing Design Data: Fetching the correct design data from Figma, specifically identifying the correct NODE_ID for the button was a challenge. The NODE_ID came from the Figma URL. The fetchfigmaData.mjs script used it to find the button component in the Figma file. We implemented a recursive function to solve this challenge. It traverses the Figma document structure and finds the node by its ID.
Handling Node.js Core Module Polyfills: Webpack 5 no longer includes polyfills for Node.js core modules by default, leading to errors when trying to use the path module. To fix this, we installed the path-browserify module. We also added a fallback configuration to webpack.config.js. This ensures that the path module can be used in the browser environment.

// webpack.config.js
module.exports = {
  resolve: {
    fallback: {
      path: require.resolve("path-browserify"),
 },
 },
};

Adding this setup helps you avoid errors. It also ensures your app runs well in browsers.

File Path Issues: Ensuring the buttonDesign.json file is correctly located and accessible by both the polling script and the React application was a challenge. To solve this, the file path was adjusted to ensure the buttonDesign.json file is saved in the src directory of the React project. The polling script was updated to use path.resolve("src/buttonDesign.json") to ensure the file is correctly located.
React Application Not Reflecting Design Changes: The React application was not reflecting design changes made in Figma. To keep the React app up to date with the latest design data, we used the nodemon tool. It watches for changes in the buttonDesign.json file. It restarts the React server when it finds changes. We also converted the fetchDesignData.js script from .mjs to .js. This change makes it work better with Node.js.

// package.json
"scripts": {
  "start": "react-scripts start",
  "start:watch": "nodemon --watch src/buttonDesign.json --exec \"npm start\""
}

This setup helps keep real-time sync. It ensures that the latest design updates always appear in your running app.

Polling vs. Webhooks: Choosing between a polling mechanism and webhooks for real-time updates was a challenge. Due to a change in the Figma subscription plan, we lacked access to Figma API webhooks. Therefore, we added a polling mechanism. This approach is not as immediate as webhooks, but it ensures that it checks and fetches design updates. The polling interval was set to a good duration: 5 minutes. This balances timely updates and API rate limits.
