# [WIP] N-API Migration Guide
## Context
Many methods that previously did not require context (e.g., `JsString::size`) now require a context. In many cases, this means adding an additional argument or using a convenience method on the `Context` trait.
### Impacted methods
* `JsString`
- `size`
- `value`
* `PropertyKey`
- `get_from`
- `set_from`
