Is Node.js 12.17.0 supported for zx as a package ?

[Cactusbone]

Hello !
I've seen the releases notes of 8.1.0 which says

Extended Node.js supported versions range: from 12.17.0 to the latest 22.x.x.

However with Node.js 12.22.12 (the one shipped with alpine 3.20, upon which docker-cli images are built), I'm getting SyntaxError: Unexpected reserved word with import {$, cd} from 'zx';

What I'm trying to achieve: I'm trying to run mocha tests (using mocha binaries), which starts and stops Docker containers, so I'm using zx as a package. And since I also need docker client, I'm using the docker-cli image, with alpine 3.20, which provides Node.js 12.22.12.

It is expected to work ? Anything I can to do work around it ?

Thanks

Expected Behavior

import {$, cd} from 'zx'

No error

Actual Behavior

import {$, cd} from 'zx'

SyntaxError: Unexpected reserved word

Steps to Reproduce

1. Use Node.js 12.22.12 (I think all Node.js 12 > 12.17.0 exhibit the issue)
2. simply import zx in a module

Specifications

• zx version: 8.1.1
• Platform: windows and docker (separately)
• Runtime: Node.js 12.22.12

Ok, I've found a workaround for Node.js 12, by using require

import {createRequire} from 'node:module';
const require = createRequire(import.meta.url);
const {$, cd} = require('zx');

I think the top level await in built index.js is not compatible with Node.js 12, should work starting with Node.js 14.8.

Nice catch, thanks!

Fix does not seem to work, I'm still getting the same error. According to documentation, main entrypoint is for Node.js <= 10

Node.js 12 does support the exports entrypoint, see https://nodejs.org/docs/latest-v12.x/api/packages.html#packages_package_entry_points

What a weird thing: it supports the import api, but not top-level await.
