Specify node version on package.json and unify "npm run dev" between server and client

Hi, I have Macbook m1 / amd and I was struggling with this error

You installed esbuild on another platform than the one you're currently using.
This won't work because esbuild is written with native code and needs to
install a platform-specific binary executable.

Specifically the "esbuild-linux-64" package is present but this platform
needs the "esbuild-darwin-arm64" package instead. People often get into this
situation by installing esbuild on Windows or macOS and copying "node_modules"
into a Docker image that runs Linux, or by copying "node_modules" between
Windows and WSL environments.

The fix was solved by updating from Node v14 to v16.
If we add the engine to package.json we could avoid this problem beforehand.

Let me know if it makes sense. Have a great day!
