# VersionManagement
The `Napi::VersionManagement` class contains methods that allow information
to be retrieved about the version of N-API and Node.js. In some cases it is
important to make decisions based on different versions of the system.
## Methods
### GetNapiVersion
Retrieves the highest N-API version supported by Node.js runtime.
```cpp
static uint32_t Napi::VersionManagement::GetNapiVersion(Env env);
```
- `[in] env`: The environment in which the API is invoked under.
Returns the highest N-API version supported by Node.js runtime.
### GetNodeVersion
Retrieves information about Node.js version present on the system. All the
information is stored in the `napi_node_version` structure that is defined as
shown below:
```cpp
typedef struct {
uint32_t major;
uint32_t minor;
uint32_t patch;
const char* release;
} napi_node_version;
````
```cpp
static const napi_node_version* Napi::VersionManagement::GetNodeVersion(Env env);
```
- `[in] env`: The environment in which the API is invoked under.
Returns the structure a pointer to the structure `napi_node_version` populated by
the version information of Node.js runtime.
