Environment Variables

Once deployed, kindly ensure you set all required environment variables in the Environment section of your hosting service.

Node.js Compatibility

The recommended version of Node.js to use in this example is Node.js v20.0.0.

If you are using a version of Node.js lower than this (for example the minimum supported node version v18.0.0), you may need to enable Web Crypto API via the --experimental-webcrypto flag in the start and dev scripts of your package.json file.

Instead of using the experimental flag, you may use the following polyfill:

// polyfill.cjs
globalThis.crypto ??= require("crypto").webcrypto

And then import it within a top-level file in the application:

// server.ts
import "./polyfill.cjs"
