I have a notice board setup at home. It has behaved itself perfectly for a long while now, but yesterday it stopped telling us the news. I told my wife the Government has heard all her comment's and shut us down.
But it turns out I was wrong.
"Important EOL Notice: As of Thursday, Jan. 3, 2019, the YQL service at query.yahooapis.com will be retired. This will impact users of datatables.org as well as developers who creates features using this YQL service. To continue using our free Yahoo Weather APIs, use https://weather-ydn-yql.media.yahoo.com/forecastrss as your new API endpoint. Contact [email protected] for credentials to onboard to this free Yahoo Weather API service. Other YQL based services that use query.yahooapis.com will no longer operate."
Now that is awesome!
I fear to say that my coding abilities are a little less than what would be bad.
It is a webserver running on a Orange pi with LAMP, with the majority of the code lifted from here
https://github.com/MichMich/MagicMirror
but an older version.
Essentially it is a webpage with weather, a calendar, clock... etc.
The RSS feeds and age of feeds to display are listed in a config.js file and the code below is the relevant section in the main.js file, it then displays the news feed titles at the bottom of the page one at a time from the various feeds.
Searching throughout the day I have found,
https://stackoverflow.com/questions/246577/can-i-serve-rss-in-json
and
as possible solutions.
It is starting to feel like I'm trying to reinvent the wheel with the spokes on the outside.
I don't want this to be a - Try this.....Not working.....try this..., thread, but some advice and guiding in the right approach would be very helpful.
TIA
My head hurts, I'm cross eyed and rather frustrated at my lack of knowledge!
