Improved paragliding sites plugin

[ivo]

Downloading backend data is not yet develop, but I add example how to Interpolate wind data from a map, so you can get flyability from a lot of point on a map

Thanks a lot @ivo, I should now be able to get a first version running, I'll work on it and publish a first version asap :)

@Okocedion How everything goes?

[Okocedion]

@tomslavkovsky I've had other priorities lately, but will start working on it again soon.

I also had to develop a proxy API for paragliding earth data, because they serve it over http when I can only use it in https in my plugin. Repo for this API is here: https://github.com/xVinCe/pg-api

So next thing I need to do is get a cheap server to host my API on (with https), and then get back to where I was on the plugin!

Hello,

A first preview version of my plugin is now published on NPM under the name windy-plugin-pg : https://www.npmjs.com/package/windy-plugin-pg

Github with an up-to-date readme: https://github.com/xVinCe/windy-plugin-pg

It only works at zoom levels > 8 to avoid having too many icons on the screen.
It updates in real-time when you press the play button :)

I am not very happy with how the icons look, I could use some help from a designer I guess ;)

@ivo My biggest limitation for the future is that I am limited to the wind layer, and can't access other infos.
Is there any chance that I may access other layers without displaying them in the future?
I would need at least wind gusts, rain and clouds (at ground level).

Big congrats. I will start working on dataLoader so plugin authors could acces our forecast data

@Okocedion Thanks for this plugin. However, it currently doesn't work due to this error:

Access to fetch at 'https://pg-api.ovh/sites/lng/12.390466781303324/15.862146468803326/lat/49.44939061604292/50.29198304347857/' from origin 'https://www.windy.com' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains multiple values '*, *', but only one is allowed. Have the server send the header with a valid value, or, if an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

The server returns the header twice:

HTTP/1.1 200 OK
Server: nginx/1.14.0 (Ubuntu)

Moreover, https://github.com/xVinCe/pg-api doesn't exist anymore so I couldn't try to fix this myself.

@jakubvrana I was able to solve it by this hack:

1. Install Header Editor.
2. Add rule Modify response header with header name Access-Control-Allow-Origin and value https://www.windy.com.
3. Add a second rule Modify response header with this custom function:

let access = false;
for (let i = 0; i < val.length; i++) {
  if (val[i].name == 'Access-Control-Allow-Origin') {
    if (access) {
      val.splice(i, 1);
    }
    access = true;
  }
}

I don't know why both these rules are needed, the first one shouldn't be needed. However if I don't add it then the headers are not modified.
