np with npm 10.5.1: Failed to parse output of npm pack

[karlhorky]

Description

Using npm@10.5.1 (latest as of 3 Apr 2024), the following error message is thrown during publish:

➜  preflight git:(main) np --yolo

✖ Error: Failed to parse output of npm pack
    at Module.getFilesToBePacked (file:///Users/k/Library/pnpm/global/5/.pnpm/np@10.0.2/node_modules/np/source/npm/util.js:147:9)

This is probably because npm pack with the flags that np uses also returns output with npm v10:

npm pack --dry-run --json --silent

> @upleveled/preflight@6.1.1 build /Users/k/p/preflight
> tsdx build --format esm --target node --tsconfig tsconfig.src.json "--silent"

  {
    "id": "@upleveled/preflight@6.1.1",
    ...

Steps to reproduce

1. Use a package with a prepare script that generates output
2. Use npm v10.5.1
3. Run np

Expected behavior

Package should be published, like it is with npm v9

Environment

np - 10.0.2 Node.js - 20.12.0 npm - 10.5.1 Git - 2.39.2 OS - macOS Sonoma 14.4.1 (23E224)

@transitive-bullshit @sindresorhus Thanks for the #743 PR and review 🙌

Will this be released in the next minor or patch version of np? eg:

• minor: np@10.1.0
• patch: np@10.0.4

Thanks!

Tried to confirm the fix with np@10.0.4 + npm@10.5.2, but still encountering the error:

This is tsdx, so it shows an animated spinner + progress bar thing during build too:

Or maybe I'm doing something wrong?

I guess an alternative workaround implementation in np could potentially use npm pack --foreground-scripts=false

[karlhorky]

Eg. maybe something like this PR:

• https://github.com/sindresorhus/np/pull/744

[karlhorky]

@sindresorhus thanks for the review and merge of my PR and publish of np@10.0.5 👍

I can confirm that np@10.0.5 is no longer failing with npm@^10 🎉
