build fails under node 21

[rcarmo]

I get an error message stating that the build configuration is broken. I have the following Node versions:

node -v
v21.7.3
npm -v
10.5.0

Log:

% npm run build                                                        

> openscad-playground@0.1.0 build
> NODE_ENV=production npx rollup --config openscad-worker.rollup.config.js && webpack --mode=production

[!] RollupError: Node tried to load your configuration file as CommonJS even though it is likely an ES module. To resolve this, change the extension of your configuration to ".mjs", set "type": "module" in your package.json file or pass the "--bundleConfigAsCjs" flag.

I keep getting the same error, trying multiple versions of Node (21, 20, 18, haven't tried other). I was planning on dockerising this project for myself (and maybe my friends).

Sorry just seeing this. Building thing successfully here (on Mac) w/ Node v22.2.0 (make public && npm run build)

[JaxTheWolf]

FROM node:18-alpine

RUN apk update
RUN apk add wget make bash git zip 

RUN mkdir /src

COPY src /src

WORKDIR /src

RUN make public
RUN npm run start:prod

This is my Dockerfile. I think I got all the dependencies right. Fails with the same error as above.

[ochafik]

@JaxTheWolf weird, that Dockerfile works for me, in the current main branch, just modified COPY . /src and ran docker build . from the repo root.

Hm, could you try running it in a Linux VM? I would try Mac OS, but that's a bit more hassle than it's worth :D

[ochafik]

Ah sorry i think my copy ‘.’ without cleaning first means it didn’t try and build everything from the container. Will try again shortly

Edit: it's not that, still works. I'll try on Linux when I get my hands on a box or VM (or will just setup some github workflows).

Error is a bit misleading. Try installing rollup-plugin-typescript2. "npm install rollup-plugin-typescript2". This worked for me on a fairly up to dat ubuntu.
