SharePoint Web Part: Definition, Uses, and Governance

A SharePoint web part is a modular component placed on a modern page to display content, data, navigation, media, or interactive functionality. Microsoft supplies standard web parts for common needs, and developers can build supported custom web parts with the SharePoint Framework when a validated requirement cannot be met through configuration or an existing component.

Current as of July 13, 2026: Microsoft's June 2026 visual refresh is rolling out to general availability across SharePoint surfaces and includes visual treatment around pages and SPFx placeholders; it does not remove the need to test custom parts. Microsoft also documented new Resources and Announcements web parts in the May–June 2026 home-site update. Web-part availability can still vary by rollout and environment.

What Web Part Means in SharePoint

Web parts are the building blocks of a modern page. An author can add text, images, quick links, news, events, lists, libraries, people, video, highlighted content, and other components, then configure each part to support the page's purpose. Some display content stored directly on the page, while others query a site, hub, library, list, or connected service.

A web part does not override source permissions. If it rolls up documents or news from another location, each viewer sees content according to their access to the source. This security trimming protects content but can make a page look different for different users, which authors must account for during testing.

Why It Matters to the Business

Standard web parts let business teams assemble useful experiences without custom development. A department can surface current policies, contacts, announcements, forms, and key links on one page while keeping each source item in its governed location.

Custom web parts can add real value when requirements are distinct, but customization also creates an asset that needs ownership, testing, security review, documentation, and maintenance. The business case should weigh the recurring support obligation against the gap in standard functionality.

What SharePoint Administrators Need to Know

Administrators should maintain an inventory of third-party and custom web parts, their package owners, deployment scope, data connections, permissions, dependencies, and support status. SharePoint Framework solutions should follow supported deployment practices and be tested when Microsoft or dependency versions change.

Page owners should test web parts for mobile behavior, accessibility, performance, empty states, permission differences, and source-content failure. A component that performs well with sample data can become slow or confusing when it queries a large, poorly classified, or inaccessible source.

What to Consider

Use standard capabilities first

Confirm whether a Microsoft web part, configuration change, or page redesign meets the need before committing to custom code.

Govern the source as well as the display

Assign ownership, metadata, permissions, and lifecycle to the list, library, feed, or system the web part surfaces.

Plan for the full component lifecycle

Document the owner, package, dependencies, accessibility, security review, test plan, deployment, update process, and retirement path for custom web parts.

Practical Takeaway

A web part is only as reliable as its source content, permission model, and long-term owner.

How This Shows Up in the Field

Intranet homepage

A home page can combine News, Events, Quick Links, People, and Highlighted Content web parts to guide employees without copying source information into static text.

Custom operational view

An SPFx web part can present data from SharePoint and an approved external API in one responsive interface when no standard component meets the business requirement.

Web part, page, and SharePoint Framework

Web part	A configurable component added to a page to present content, data, navigation, media, or an interaction.
Modern page	The responsive canvas that arranges sections and one or more web parts into a coherent user experience.
SharePoint Framework	Microsoft's supported client-side development model for building and packaging custom web parts and extensions.

Related SharePoint Glossary Terms

Modern SharePoint PageA modern SharePoint page is a responsive publishing canvas stored in a site's Site Pages library and assembled with sections and web parts. Authors use modern pages for homepages, news, guidance, dashboards, and intranet content that adapts across devices, supports accessible design, and can surface information from SharePoint and connected Microsoft 365 services. Communication SiteA SharePoint communication site is a modern site designed for a small group of authors to publish news, resources, reports, and other information to a broad audience. Unlike a standard group-connected team site, creating a communication site does not create a Microsoft 365 Group, and its access is normally managed with SharePoint Owners, Members, and Visitors. Hub SiteA SharePoint hub site connects a family of related team sites and communication sites through shared navigation, branding, scoped search, and content rollups. Hub association expresses a relationship between separate sites; it does not create a fixed parent-child hierarchy, merge the sites into one site collection, or automatically grant users access to associated content. Document LibraryA SharePoint document library is a specialized content area for storing, organizing, sharing, and governing files. Unlike a basic network folder, a library can apply columns and metadata, content types, views, version history, approvals, retention settings, automation, and permission controls so documents can participate in search and business processes across Microsoft 365. SharePoint ListA SharePoint list is a structured collection of items organized by columns, similar to a lightweight business table with forms, views, rules, permissions, and versioning. Organizations use lists to track requests, assets, tasks, issues, contacts, approvals, and other repeatable information, often connecting them to Power Automate, Power Apps, pages, Teams, and reporting tools. SharePoint Framework (SPFx)The SharePoint Framework (SPFx) is Microsoft’s supported client-side extensibility model for building custom SharePoint and Microsoft 365 experiences with modern web technologies. Developers package web parts, extensions, libraries, and related components for controlled deployment through an app catalog while respecting the permissions and hosting patterns of Microsoft 365.

Frequently Asked Questions

What does a SharePoint web part do?

It adds a specific display or function to a page, such as text, news, links, events, documents, list data, people, video, search-driven content, or a custom interactive experience.

Are web parts available on classic and modern pages?

Modern pages use modern client-side web parts. Classic pages use a different web-part and customization model, and classic components do not automatically work on modern pages. Modernization may require replacement or redesign.

Can a web part show content a user cannot access?

Standard dynamic web parts generally respect the underlying source permissions and security trim results. Page owners should still test different user profiles because a missing source permission can produce empty or different experiences.

When should an organization build a custom web part?

Build one when a validated, valuable requirement cannot be met through standard components, configuration, or process redesign—and when the organization can own security, accessibility, testing, deployment, updates, and support.
