# StackBlitz Install & Auth ## Overview Set up the WebContainer API for running Node.js in the browser, or the StackBlitz SDK for embedding interactive code editors. WebContainers require no auth -- they run entirely client-side. The StackBlitz SDK is for embedding projects from stackblitz.com. ## Prerequisites - Node.js 18+ for build tooling - Modern browser with SharedArrayBuffer support (requires HTTPS + COOP/COEP headers) ## Instructions ### Step 1: Install WebContainer API ```bash npm install @webcontainer/api ``` ### Step 2: Install StackBlitz SDK (for embedding) ```bash npm install @stackblitz/sdk ``` ### Step 3: Configure Required HTTP Headers WebContainers require cross-origin isolation. Add these headers to your server: ```typescript // Express middleware app.use((req, res, next) => { res.setHeader('Cross-Origin-Embedder-Policy', 'require-corp'); res.setHeader('Cross-Origin-Opener-Policy', 'same-origin'); next(); }); ``` ```javascript // Vite config export default defineConfig({ server: { headers: { 'Cross-Origin-Embedder-Policy': 'require-corp', 'Cross-Origin-Opener-Policy': 'same-origin', }, }, }); ``` ### Step 4: Verify WebContainer Boot ```typescript import { WebContainer } from '@webcontainer/api'; const wc = await WebContainer.boot(); console.log('WebContainer booted successfully'); // Verify filesystem works await wc.mount({ 'test.txt': { file: { contents: 'Hello WebContainers!' } } }); const content = await wc.f...
