The upgrade of js-yaml from v4 to v5 is a major version jump with significant breaking changes that require code modifications. The library has been fundamentally reworked for safety and modern JavaScript standards.

Key Breaking Changes:

• Safe by Default: The primary breaking change is that the main load() function is now safe by default, and the unsafe safeLoad() function has been removed. This is a critical security improvement, as the previous load() could lead to arbitrary code execution. All calls to safeLoad() must be replaced with load().

• ESM Named Exports: The package no longer uses a default export. Code must be updated to use named imports.

  • Before (v4): const yaml = require('js-yaml'); yaml.safeLoad(doc);
  • After (v5): const { load } = require('js-yaml'); load(doc); or import { load } from 'js-yaml';

• Default Schema Change: The default schema has changed from a YAML 1.1-based schema to the more modern and secure YAML 1.2 CORE_SCHEMA. This means some features like merge keys (<<) are no longer supported by default and must be explicitly enabled if needed.

• API and Behavior Changes:

  • Loading an empty string (load('')) now throws an error instead of returning undefined.
  • The API for creating custom types has been completely replaced.
  • Unsafe tags like !!js/function and !!js/regexp have been removed from the core library.

Recommendation: This upgrade requires careful code review and modification. Developers must update import statements, replace safeLoad with load, and verify that their YAML documents are compatible with the new default schema. Due to the fundamental nature of these changes, thorough testing is essential.
