By Joe Previte` A developer shares their experience of releasing a custom React component, hook, or effect as an npm package. They started by setting up a boilerplate using create-react-hook, which provided a simple way to create reusable React hooks. The developer created a custom React component, hook, and effect, tested them locally, and then published the package on the npm registry. To publish, they logged in with their npm credentials, checked the version, updated the README file, checked the version again, published the package, tested it in a CodeSandbox, and finally verified it was working in a "production" environment. The developer concludes that releasing custom React packages is not as intimidating as it seems, thanks to tools like create-react-hook and npm/yarn link.
