A graphql microservice that parses rss feeds and returns a JSON representation of the given feed. It uses different parses installed from npm. When a parser fail it will try the next following this order: feedparser, rss-parser, feedme, rss-to-json. To specify a specific parser see example queries below.

Installation

npm i -g graphql-rss-parser

Usage

CLI for starting the server

$ graphql-rss-parser --help

  Usage: graphql-rss-parser [options] [command]

  Commands:

    help  Display help

  Options:

    -h, --help          Output usage information
    -H, --host [value]  Host to listen on (defaults to "0.0.0.0")

Sentry integration

The sentry integration can be enabled by passing the -D/--sentry-dsn cli option. It is important to note that errors that happens because errors in parsers or http requests will be filtered out. This is because the goal of this error tracking is to catch errors in the code of the service.
