Expand Up @@ -39,6 +39,20 @@ CommonJS keeps working through destructuring:
const { load, dump } = require('js-yaml')
```

If you want to keep the old namespace-style calls, import the ESM namespace
instead:

```js
import * as yaml from 'js-yaml'

yaml.load(source)
yaml.dump(data)
```

js-yaml v5 does not provide an ESM default export by design. Prefer named
exports for new code, or use the namespace import above when migrating code that
expects `yaml.load()` / `yaml.dump()`.

Exports are now flat. The `types` namespace, the `Type` class and
`DEFAULT_SCHEMA` are gone, and internal `js-yaml/lib/...` imports no longer
resolve. If you used any of those, read on.
