RSS API based on AWS Lambda, Dynamodb, Api Gateway and Python

This aplicatoion uses 3 levels:

1. Categories (parent = 'root');
2. Feeds (parent = category id);
3. Item (parent = feed id);

• FeedMeReSSt:
  CRON that read RSS sources from time to time.

• ReSStCRUD:
  API for RSS/OPML item.

• ReSStOPMLImport:
  API to import sources from OPML xml file.

Static user interface (WIP).

It can be hosted by Github Pages.

https://hugosenari.github.io/ReSSt/ReSStUI/

• ReSSt:
  uid, parent: RSS items/sources.

• parent:
  parent, imported_at: because most of search is parent based.

• feeds:
  xmlUrl, parent: list all feed sources.

• unread:
  unread_since, parent: has only unread items.

Import feed sources from OPML file

• POST
  Expect OPML xml in body.

CRUD operations for sources/items

  • tree=string, make a tree of item/source by uid;
  • title=string, scan by item/source title;
  • link=string, scan by item link;
  • xmlUr=string, scan by source url;
  • star=var, show stared items only;
  • read=var, show read items only;

Since it does't have CloudFormation file yet, is not easy install it on AWS. Good look!

• Create three python3 functions:
  • Two for api gateway (ReSStCRUD, ReSStOPMLImport).
  • One for cloudwatch (FeedMeReSSt).
• Create one DynamoDB table (ReSSt).
• Create three index (parent, feeds, unread).
• Publish ou api and create a API-KEY.
• Upload ReSStUI to somewhere.

• Fix TODO in this README;
• Fix security issues;
• Convert to servless/chalice;
• Add suport to multi user;
• make all this ugly code pretty;
• push notifications;
