Utility to recursively stringify and error object with causes

stringify-error-chain.ts

export const stringifyErrorChain = (error: unknown, level = 0) => {
	let current: unknown = error;
	const lines: string[] = [];

	while (current instanceof Error) {
		const indent = '    '.repeat(level);

		lines.push(`${indent}${current.name}: ${current.message}`);

		current = current.cause;

		level += 1;
	}

	return lines.join('\n');
};
