Google Photos API changing - MMM-GooglePhotos will stop working soon.

@Andresleonsalas I use an updated version of MMM-ImagesPhotos

see my fork https://github.com/sdetweil/MMM-ImagesPhotos

supports recursive image folder…

I am picky about displaying my photos…
I don’t want cover or contain, I want consistent aspect ratio…
fit vertical or horizontal and adjust the other to the physical size…

@sdetweil Thanks. I got that up and running. One thing I wish it had (and I don’t think any module does). I’d like to show some of the EXIF data.
At a minimum, the date the photo was taken, but ideally, also lookup the location and display that in a friendly manner (i.e. City, State, Country)

I thought, “that shouldn’t be too hard” but I don’t understand modules and the relationship of node helper to the main js. I’m not sure how to load the appropriate library to access the exif data.

@gonzonia modulename.js runs in a browser
but a browser cannot access files, except thru a web server,
also cant access hardware (gpio)

so the node_helper runs on server as task, so it can

there is an api to send request to helper and get response back,
this module uses another trick, by accessing a web link to a file

anyhow , here is a drawing i did years ago to explain this, its truncated on the side on purpose, as its just repetitive

my sample module shows all that operation
https://github.com/sdetweil/SampleModule

anyhow, one could extend the response to include the exif data

here is a nodejs lib that does exif
https://www.npmjs.com/package/exif

@sdetweil Thanks. That’s helpful. But I think it’s still above my pay-grade. I may poke around and see if I can figure something out, but I’m not sure I can. I conceptually understand what’s happening, but don’t see it in the code in a way that is clicking for me such that I can just make a call to an Exif method where it pulls the data from the file.

I’ve come across a couple of other modules who are doing some of it, but again, I’m not quite sure I understand how the data is being passed around so that I can correctly apply the logic in the right place.

@sdetweil MMM-BackgroundSlideshow seems to do exactly what I want, but I think your handling of formatting the images is better.
