Built with Bolt Figma button graphics:

PNG Files

SVG Files

Prerequisites

• Node.js 18 or later
• Package manager either
  • NPM (comes with Node.js)
  • Yarn ( ensure by running yarn set version classic )
  • PNPM ( ensure by running pnpm --version )
• Figma Desktop App

Quick Start

Create your new Bolt Figma project (follow CLI prompts)

• yarn - yarn create bolt-figma
• npm - npx create-bolt-figma
• pnpm - pnpm create-bolt-figma

Change directory to the new project

• cd project

Install Dependencies (if not already done by create command)

• yarn - yarn
• npm - npm i
• pnpm - pnpm i

Build the plugin (must run before dev, can also run after for panel to work statically without the process)

• yarn yarn build
• npm npm run build
• pnpm pnpm build

Run the plugin in hot reload mode for development

Note: Ensure "Hot reload plugin" is checked in Figma Plugin Development menu

• yarn yarn dev
• npm npm run dev
• pnpm pnpm dev

Bundles your plugin and specified assets from copyZipAssets to a zip archive in the ./zip folder

• yarn yarn zip
• npm npm run zip
• pnpm pnpm zip

Write frontend UI code in src/main.svelte

Write backend figma code in src-code/code.ts

Add Plugin to Figma

1. Open Figma
2. Select Figma Menu > Plugins > Development > Import Plugin from Manifest
3. Select the manifest.json file in the dist folder
4. Your plugin can now be launched from the menu or managed under "Manage Plugins"

Load and Debug Plugin

1. Launch your plugin by going to Figma Menu > Plugins > Development > "Your Plugin"
2. Ensure Hot Reloading is checked under Figma Menu > Plugins > Development > Hot Reloading Plugin
3. Open the Dev Tools console with Figma Menu > Plugins > Development > Show/Hide Console

Sending Messages between the Frontend and Backend

Bolt Figma makes messaging between the frontend UI and backend code layers simple and type-safe. This can be done with listenTS() and dispatchTS().

Using this method accounts for:

• Setting up a scoped event listener in the listening context
• Removing the listener when the event is called (if once is set to true)
• Ensuring End-to-End Type-Safety for the event

1. Declare the Event Type in EventTS in shared/universals.ts

export type EventTS = {
  myCustomEvent: {
    oneValue: string,
    anotherValue: number,
  },
  // [... other events]
};

2a. Send a Message from the Frontend to the Backend

Backend Listener: src-code/code.ts

import { listenTS } from "./utils/code-utils";

listenTS("myCustomEvent", (data) => {
  console.log("oneValue is", data.oneValue);
  console.log("anotherValue is", data.anotherValue);
});

Frontend Dispatcher: index.svelte or index.tsx or index.vue

import { dispatchTS } from "./utils/utils";

dispatchTS("myCustomEvent", { oneValue: "name", anotherValue: 20 });

2b. Send a Message from the Backend to the Frontend

Frontend Listener: index.svelte or index.tsx or index.vue

import { listenTS } from "./utils/utils";

listenTS(
  "myCustomEvent",
  (data) => {
    console.log("oneValue is", data.oneValue);
    console.log("anotherValue is", data.anotherValue);
  },
  true,
);

Note: true is passed as the 3rd argument which means the listener will only listen once and then be removed. Set this to true to avoid duplicate events if you only intend to recieve one reponse per function.

Backend Dispatcher: src-code/code.ts

import { dispatchTS } from "./utils/code-utils";

dispatchTS("myCustomEvent", { oneValue: "name", anotherValue: 20 });

Info on Build Process

Frontend code is built to the .tmp directory temporarily and then copied to the dist folder for final. This is done to avoid Figma throwing plugin errors with editing files directly in the dist folder.

The frontend code (JS, CSS, HTML) is bundled into a single index.html file and all assets are inlined.

The backend code is bundled into a single code.js file.

Finally the manifest.json is generated from the figma.config.ts file with type-safety. This is configured when running yarn create bolt-figma, but you can make additional modifications to the figma.config.ts file after initialization.

Read if Dev or Production Mode

Use the built-in Vite env var MODE to determine this:

const mode = import.meta.env.MODE; // 'dev' or 'production'

Troubleshooting Assets

Figma requires the entire frontend code to be wrapped into a single HTML file. For this reason, bundling external images, svgs, and other assets is not possible.

The solution to this is to inline all assets. Vite is already setup to inline most asset types it understands such as JPG, PNG, SVG, and more, however if the file type you're trying to inline doesn't work, you may need to add it to the assetsInclude array in the vite config:

More Info: https://vitejs.dev/config/shared-options.html#assetsinclude

Additionally, you may be able to import the file as a raw string, and then use that data inline in your component using the ?raw suffix.

For example:

import icon from "./assets/icon.svg?raw";

and then use that data inline in your component:

// Svelte
{@html icon}

// React
<div dangerouslySetInnerHTML={{ __html: icon }}></div>

// Vue
<div v-html="icon"></div>
