# RSS Reader

## Summary

A RSS Reader original based on work completed by Olivier Carpentier's from:  https://github.com/OlivierCC/spfx-40-fantastics/tree/master/src/webparts/rssReader
Root project: https://github.com/OlivierCC/spfx-40-fantastics

React RSS Reader utilizes SharePoint Framework v1.11.0 with no dependency on jQuery or a RSS Feed library. This project does utilize https://sharepoint.github.io/sp-dev-fx-property-controls/, and Moment React for date manipulation. Handlebar template option derived from React Search Refiners (PnP Modern Search): https://microsoft-search.github.io/pnp-modern-search/. Use NodeJS version 10 to compile or rebuild the spfx solution.

Main features include:

- Three different RSS Feed retrieval services, direct, https://feed2json.org, https://rss2json.com
- Optionally store RSS feed results to local storage for quick reload with configurable timeout window
- Optional CORS proxy service for cross origin feeds
- Optional View All link in header to point to custom feed source
- Embedded feed rendering with optional parameters
