Pitfalls of Deploying Hono Js App on Vercel
Hono does have a template application for Vercel, but in my case, my requirements were different (aren't they always 😅). I was working in a monorepo (using nx) because I wanted to manage my libs, tests, and examples all together in a single place, instead of having different repos.

How to setup semantic release with GitHub Actions.
Recently, My coworker is using Nx to automate his workflow, including automated release using semantic version. I found this method quite useful, so I want to re-implement on single GitHub repositories (without Nx).

Unit Testing Expo Apps With Jest
console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation
