WopiHost wiki

The README covers what WopiHost is and how to run the samples in two minutes. Everything else lives here.

Concepts

• Architecture — how the libraries, providers, frontend, and WOPI client fit together at runtime.

Configuration & operations

• Configuration — Wopi:* and AppHost:* knobs.
• Hosting — running individual projects, IIS, HTTPS, Docker, older runtimes.
• End-to-end editing with Collabora Online — using CODE as a real WOPI client for development and CI.

Extending the host

• Extending WopiHost — custom storage and lock providers, permissions, the minimal-host snippet.
• CheckFileInfo customization — overriding the response payload via IWopiHostExtensions hooks.
• Bootstrap endpoint — wiring /wopibootstrapper for Office mobile.

Cobalt (MS-FSSHTTP)

• Cobalt — what it is, why it's optional, why the build complains.
• Craft your own Microsoft.CobaltCore NuGet package — building the proprietary package from a licensed OOS / SharePoint installation.

Reference

• Useful resources — WOPI / MS-FSSHTTP specs and external write-ups worth bookmarking.
• Interesting WOPI projects — curated list of other WOPI host implementations and what's worth a look in each.
