Why do I get Cannot GET / instead of the site when I run npm run start?

Question

Node.js

Good afternoon. I watched a video by Vadim Makeev and decided to reproduce the assembly at home. But when I run the "npm start" command, instead of the site at localhost:3000 I get Cannot GET / . The sources are identical to the sources from the video.

{
  "private": true,
  "scripts": {
    "start": "browser-sync start --server 'src' --no-notify --no-ui --cwd 'src' --files 'index.html,styles/**/*'",
    "test": "editorconfig-checker",
    "html": "html-minifier --remove-comments --collapse-whitespace --input-dir src --output-dir docs --file-ext html",
    "styles": "postcss src/styles/index.css --use postcss-import --use postcss-csso --no-map --output docs/styles/index.css",
    "build": "npm run html && npm run styles",
    "deploy": "cd docs && rsync --archive --compress --delete . [email protected]:/var/www/pepelsbey.dev/html/"
  },
  "devDependencies": {
    "browser-sync": "^2.26.7",
    "editorconfig-checker": "^3.1.0",
    "html-minifier": "^4.0.0",
    "postcss-cli": "^7.1.1",
    "postcss-csso": "^4.0.0",
    "postcss-import": "^12.0.1"
  }
}

Answer 1

Answer 2

Is there static? The path to static is wrong.
