Shouldn't this be outside? What if there is a goldenFile and cycles?

This is within the goldenFile being undefined so there is no golden file.

But shouldn't this fail? if there are cycles and goldenFile being !== undefined?

I guess it will happen automatically below with the comparison. That's the thing I missed. Very confusing :D

For the case where there is no golden file, and there are cycles here. This fails as it returns a 1 as the exit code.

For cases where there is a golden file to do the comparison to later, we check the specifics.

Log.error(`x No circular dependencies are allow within this repository.`);
return 1;
}

Log.info(green('✔ No circular dependencies found in this repository.'));
return 0;
}

if (approve) {
writeFileSync(goldenFile, JSON.stringify(actual, null, 2));
Log.info(green('✔ Updated golden file.'));
return 0;
}

Wouldn't this always exist after writing before?

The file would only be guaranteed to be written to, if an approval happened. If its a regular check, then it wouldn't be written in the block above, and could technically not exist. We verify it exists because just below here we read from it to do the actual comparison.

Log.error(`x Could not find golden file: ${goldenFile}`);
return 1;
}

const expected = goldenFile ? (JSON.parse(readFileSync(goldenFile, 'utf8')) as Golden) : [];
const {fixedCircularDeps, newCircularDeps} = compareGoldens(actual, expected);
const isMatching = fixedCircularDeps.length === 0 && newCircularDeps.length === 0;
