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 )
Express Desktop App

Quick Start

Create your new Bolt Express project (follow CLI prompts)

yarn - yarn create bolt-express
npm - npx create-bolt-express@latest
pnpm - pnpm create-bolt-express

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 addon (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

Setup Keys for development (Only Once Per Dev Machine)

The first time you debug an Express Addon on a machine you need to setup auth keys by following the CLI prompts. Once you've complted this once with Bolt Express or directly with @adobe/create-ccweb-add-on you don't need to do it again on that machine.

yarn yarn cert
npm npm run cert
pnpm pnpm cert

Run the addon in hot reload mode for development

The first time you run yarn dev you will be promted to make a dev cert.

On Windows, press OK on the popup dialog.

On MacOS, enter your password in the CLI when prompted and press enter to create the cert.

You won't need to do this in the future.

yarn yarn dev
npm npm run dev
pnpm pnpm dev

Bundle your addon and specified assets from copyZipAssets to a zip archive in the ./zip folder

yarn yarn zip
npm npm run zip
pnpm pnpm zip

Add Addon to Express

Open Express in your browser (Edge on Windows, Safari on MacOS)
Open Document
Select Add-ons from left sidebar
Select "Your add-ons"
Toggle "Add-on testing"
With correct serve port number, check "I Understand..." and press "Connect"

Load and Debug Addon

Launch your addon by clicking on the icon of your Addon in the "In Development" section of "Your Add-ons"
Open the Dev Tools by right click > Inspect

Start Coding

Write frontend UI code in src/main.svelte / src/main.tsx / src/main.vue
Write backend express code in src-code/code.ts

Sending Messages between the Frontend and Backend

Bolt Express makes messaging between the frontend UI and backend code layers simple and type-safe.

Simply write your functions in code.ts on the backend, and import the sandbox variable to call the sandbox functions from the frontend with full type-safety:

1. Write Function in Backend src-code/code.ts

const sandboxApi = {
  myFunction: (a: string, b: number) => {
    // do stuff
    return true;
  },
};

2. Call that Function from the Frontend

Frontend: src/main.svelte / src/main.tsx / src/main.vue

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

const helloWorld = async () => {
  let result = await sandbox.myFunction("hello", 400);
  console.log(result);
};

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 run the build process outside of the @adobe/ccweb-add-on-scripts process to improve speed in development.

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

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