set PORT=11501 && set HTTPS=true && npm start # Windows PORT=11501 HTTPS=true npm start # macOS/Linux CRA will generate a self-signed certificate. Warning: You will need to click through the browser error once. Vite makes it trivial:
const https = require('https'); const fs = require('fs'); const express = require('express'); const app = express(); const options = key: fs.readFileSync('localhost-key.pem'), cert: fs.readFileSync('localhost.pem') ;
next dev --experimental-https --port 11501 To avoid self-signed warnings, place mkcert generated certificates in the root directory and add to next.config.js . Angular CLI uses a built-in dev server. Enable HTTPS:
In the modern world of web development, encountering a URL like https://localhost:11501 is becoming increasingly common.
