Meteor-files: Get GeoJson File as Object

[fillipefeitosa]

Dear Team,

Loved to use use your package so far. I found myself with a GeoJson problem.

I use a regular form to upload a GeoJson file. No big deal. Problem is to get this file and use it to generate the map on _Leaflet_.

Template.mapDropdown.events({
    "change #mapFilesDropDown": function(event, template){
         event.preventDefault();
         console.log(event.target.value);
         var mapId = event.target.value;
         var myMap = Maps.findOne(mapId);
         console.log(myMap.path);
    }
});

This event get the File _id to return the selected GeoJson file. MyMap.path gives me the absolute path (assets/app/uploads/Maps/dnHkQkceumTKmLGSR.geojson), but I cant reach it...

How do I get the GeoJson file as a Json Object?, and use this object to generate my leaflet map? (this one is on me :D )

Hello @fillipefeitosa ,

Glad to hear you've found a use in our package 😃
Please use .link() method to get "downloadable" URL to uploaded file. Let me know if this method will work for you.

Thanks for the fast response!!

.link() gave me:

http://localhost:3000/cdn/storage/Maps/dnHkQkceumTKmLGSR/original/dnHkQkceumTKmLGSR.geojson

I am on development env. Am I supposed to use that on production?
Thanks again

@fillipefeitosa yes 👍

Sorry for the stupid question...

But how would I test the functionality to retrieve the file and parse the JSON before launch to production?

@fillipefeitosa usually it's done with running alpha/beta/staging stages.

I solved by setting a downloadRoute

export const Maps = new FilesCollection({
    collectionName: 'Maps',
    allowClientCode: true,
    downloadRoute: '/public/',

    onBeforeUpload(file){
        if(file.size <= 10485760 && /json|geojson/i.test(file.extension)){
            return true;
        }
        return 'Favor fazer upload de geojson válido';
    }
});

Thanks for your time and great work,

Great @fillipefeitosa ,

I'm glad this one is solved quickly.
Please, keep in mind downloadRoute just a "fence" route, unless FilesCollection is initiated with public option.

Feel free to close it in case if the issue is solved on your end.
