# Build your first Field Customizer extension

> [!WARNING]
> Microsoft [announced field customizers are deprecated](https://support.microsoft.com/en-gb/office/support-update-for-sharepoint-framework-field-customizers-in-lists-and-document-libraries-0eccc64e-4512-47df-9da0-d855be22fb0a#) on June 13, 2025, and will be retired on June 30, 2026. Consider [ListView Command Set extensions](./building-simple-cmdset-with-dialog-api.md) or [use column formatting to customize SharePoint](../../../declarative-customization/column-formatting.md) instead of field customizers.

Extensions are client-side components that run inside the context of a SharePoint page. Extensions can be deployed to SharePoint Online, and you can use modern JavaScript tools and libraries to build them.
