Good tip! Also: `npx npm-packlist` to just get a list of files. The latest bin is packlist version 2, which targets npm v7 and has some very slight changes from npm v6 (see npm-packlist readme), so you can future proof your package.
🔥 Use `npm pack --dry-run` to do everything that pack usually does without actually packing anything.
