# my.SDKVersion

> Get the version of the Mini Program basic library.

Use this property to retrieve the current SDK version of the Mini Program basic library.

<Warning>
  Do not rely on this value for code logic. This property is for reference and debugging purposes only.
</Warning>

## Return Value

| Type   | Description                             |
| ------ | --------------------------------------- |
| String | The version number of the basic library |

## Code Example

```javascript theme={null}
Page({
  onLoad() {
    // Get SDK version
    const version = my.SDKVersion;
    console.log('SDK Version:', version);
  },

  showVersion() {
    my.alert({
      content: `SDK Version: ${my.SDKVersion}`
    });
  }
});
```

## Notes

* This is a synchronous property access, not a function call
* The version format follows semantic versioning (e.g., "1.2.3")
* Use [my.canIUse](/jsapi/basic/my.canIUse) instead for feature detection

<Tip>
  For determining feature availability, always use `my.canIUse()` rather than checking the SDK version directly. This provides more reliable and maintainable code.
