graphql-rss-parser
npm version

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

```shell
npm i -g graphql-rss-parser
```

## Usage

### CLI for starting the server

```shell
$ graphql-rss-parser --help

OPTIONS:
--port, -p - Port to listen to [env: PORT] [optional]
--host, -H - Host to listen to [env: HOST] [optional]
--sentry-dsn, -D - SENTRY DSN. This is used to configure logging with sentry.io [env: SENTRY_ENV] [optional]
--log-level, -L - "fatal" | "error" | "warn" | "info" | "debug" | "trace" | "silent" [env: LOG_LEVEL] [optional]

FLAGS:
--csrf-prevention, -C - Toggle for CSRF prevention [env: CSRF_PREVENTION]
--pretty-log, -P - Log human readable instead of JSON [env: PRETTY_LOG]
--help, -h - show help
--version, -v - print the version
```

### 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.

### Example queries

#### feed(url: String, [parser: Parser])

```graphql
{
feed(url: "https://rolflekang.com/feed.xml") {
title
entries {
title
pubDate
link
}
}
}
```

##### Specifying the parser

graphql-rss-parser supports several of the rss parsers on npm. It can be specified with the parser option in a feed query as seen below.

Available parsers:

* `FEEDPARSER` - [feedparser][]
* `RSS_PARSER` - [rss-parser][]
* `FEEDME` - [feedme][]
* `RSS_TO_JSON` - [rss-to-json][]
* `JSON_FEED_V1` - internal see `src/parsers/jsonfeed-v1.ts`

```graphql
{
feed(url: "https://rolflekang.com/feed.xml", parser: FEEDPARSER) {
entries {
link
}
}
}
```

#### findFeed(url: String)

```graphql
{
findFeed(url: "https://rolflekang.com") {
link
}
}
```
