[**BlockSuite API Documentation**](../../../../README.md) *** [BlockSuite API Documentation](../../../../README.md) / [@blocksuite/std](../../README.md) / [index](../README.md) / BlockService # Class: ~~`abstract` BlockService~~ ## Deprecated BlockService is deprecated. You should reconsider where to put your feature. BlockService is a legacy extension that is used to provide services to the block. In the previous version of BlockSuite, block service provides a way to extend the block. However, in the new version, we recommend using the new extension system. ## Extends - [`Extension`](../../../store/classes/Extension.md)
