Implementation detail

News source

Fetch news from the api that Google News ui use https://news.google.com/_/DotsSplashUi/data/batchexecute, parse its response data to get useful info of it.

With three different request bodies, we can get partial news of news topics (4 or 6 news per topic) with three sections:

headline
nation, world
business, technology, entertainment, sports, science, health

Every topic have an id, we can use this id to get the full news of the topic.

All of those task is done on client side, so proxy is required to bypass CORS error.

Language & region

To get news from Google News api, we need to pass a language and region code to request body, for example, US news will be "US:en". It can be easily obtained when open Google News website, and it will redirect to your local region news with ceid url params like https://news.google.com/topstories?hl=en-US&gl=US&ceid=US:en. But with proxy it can't be done by this because redirected request will not apply proxy rule to it (it will start with https://news... but only /news...), and CORS error will occur.

So in implement here is using a geolocation api service, to use user ip address to obtain user's current location country, get full language & region list from Google News api, and then filter it out to find one match. If in case it not match to single region, a selection will show up for user to select. It only needed when user first visit this site.
