proposal-hashbang VS zx

Before ECMAScript 2023 (ES14), executing a JavaScript file directly from the command line required manually specifying the interpreter path in the first line of the module. This process could vary depending on the operating system and Node.js installation.ES14 standardizes the use of hashbangs (#!) in JavaScript modules, enabling direct execution without the need for explicit interpreter invocation. The hashbang syntax is a simple convention that indicates the interpreter to be used for executing a module. It consists of a shebang (#!) followed by the path to the interpreter and optionally any arguments. For a JavaScript file, the hashbang line typically includes the path to the Node.js executable.

Hashbang Grammar

Hashbang Grammar: match de-facto usage in some CLI JS hosts that allow for #! Shebangs / Hashbang.

But if you just wanted to execute it directly then you could use a shebang because everything after the bang is interpreted and not the bang its self. Most js engines allow this in some form. Here is a proposal to standardize it. https://github.com/tc39/proposal-hashbang

When zx first appeared, it was a tiny esm script that just proposed a new idea for how child_process.spawn API could be enhanced with string template literals.

TIL about zx! https://github.com/google/zx

This suite of tools feels indispensable. Anything to keep me from having to write/maintain bash scripts that are more than a series of commands.

Great point! According to https://github.com/oven-sh/bun/blob/b433beb016470b87850f3c01..., Bun Shell took inspiration from zx[0], dax[1] and bnx[2]

If you want test it, you can run this script withzx :

I really love writing with zx. https://github.com/google/zx

We have some folks who have gone wild copy-pasting random fancy bash snippets into various developer helpers scripts. Zx did like 90% of that stuff out of the box, without being a pile of chaotic custom bash.

I ended up using this for my cli scripting needs. https://github.com/google/zx
