A quick demo showing how RSS feeds from library OPACs return the same basic data regardless of the system.
const FeedParser = require('feedparser');
const request = require('request'); // for fetching the feed
var results = '';
// var req = request('https://mylibrary.brimbank.vic.gov.au/cgi-bin/koha/opac-search.pl?idx=su&q=women%2520computer&count=50&sort_by=acqdate_dsc&format=rss2') // Brimbank (Koha ILS, RSS2)
// var req = request('https://librarysearch.melbourne.vic.gov.au/cgi-bin/spydus.exe/ENQ/OPAC/BIBENQ?QRY=SU%3A%20(WOMEN%20%2B%20COMPUTER)&QRYTEXT=Subject%3A%20women%20computer%20(Keywords)&SETLVL=SET&CF=BIB&SORTS=DTE.DATE1.DESC&FMT=RSS&XSLT=rss.xsl&NRECS=30') // Melbourne (Civica Spydus, RSS)
var req = request('https://coyl.swft.ent.sirsidynix.net.au/client/rss/hitlist/coylnow/qu=women+computer&lm=COYL-S&rt=false%7C%7C%7CSUBJECT%7C%7C%7CSubject') // Yarra (SirsiDynix Symphony, Atom)
var feedparser = new FeedParser();
req.on('error', function (error) {
console.error(error);
});
req.on('response', function (res) {
var stream = this; // `this` is `req`, which is a stream
if (res.statusCode !== 200) {
this.emit('error', new Error('Bad status code'));
}
else {
stream.pipe(feedparser);
}
});
feedparser.on('error', function (error) {
console.error(error);
});
feedparser.on('readable', function () {
var stream = this;
var meta = this.meta;
var item;
while (item = stream.read()) {
results += `<a href=${item.link}>${item.title}</a><br>`
}
});
function getResults() {
return new Promise((resolve, reject) => {
feedparser.on('end', function () {
resolve(results)
})
});
}
module.exports.endpoint = async function(req, res) {
let data = await getResults();
res.end(data);
}
