To deploy your application at GitHub pages, you'll need to add a home page property to your package.json which points to the deployed base URL of your GitHub Pages site.
NOTE: This will break deployments to other hosting services such as Netlify, Vercel, or AWS Amplify, so if you later wish to deploy there, remove this property completely
{
"homepage": "https://yourname.github.io/repository-name"
}
Your Scripts section should have the following, so that you can easily run tests locally and in your CI
"scripts": { "start": "node index.js", "lint": "eslint **/*.js", "test": "jest --verbose --coverage", "test-watch": "jest --watchAll --verbose --coverage" },
If you are creating a module to deploy at NPM, you'll want a "bin" section that identifies the name of the global command to run and your .js file that runs when called.
"bin": { "fetch": "index.js" }
Additionally, that file should have as it's first line, so that it'll run without having to type "node filename.js" every time
#!/usr/bin/env node
