Just starting out with Angular!
Am I correct in assuming that when creating a service, you request JSON data from a server controlled by someone else?
For example, if I wanted to develop a Weather app, where could I find the JSON data? Is there a standard place to research this information?
Thank you
In the event that you are trying to access data that does not belong to you within the same domain, you will need to query the API directly from the server of the data provider. This must be done unless the data provider has a JSONP implementation in place. The reason for this is due to the restrictions on cross-resource requests within the browser, requiring such actions to be performed server-side (e.g. using PHP). Learn more about the Same-origin Policy here.
It's worth noting that if the server permits CORS (Cross-Origin Resource Sharing), it is possible to make these queries using JavaScript as well. However, most APIs do not support CORS by default. Learn more about CORS here.
If you're looking to access weather data, check out this helpful website that offers detailed documentation on how to utilize their API: openweathermap.org/current
