I have a server ruing a website. I need this server to be able to administer (only downstream) notifications to three separate device groups, Android, iOS, and a client-side web app.
I am trying to use firebase cloud messaging. With FCM, I plan on using the http protocol to send json messages.
Aside from this, I am pretty confused about where to go. I know that GCM tutorials should pretty much be exactly the same as FCM tutorials, but I am having trouble finding a tutorial to figure out what I need to be doing, as each tutorial seems to mix up the server and client side applications together, which is confusing me.
I have been through
https://firebase.google.com/docs/cloud-messaging/server#choose
pretty thoroughly but it seems to gloss over some requisite knowledge that I don't have yet. Can anyone suggest a good starting place on how to implement FCM in the maer I am looking for? I am overall very new to web dev, less than 2 months, (using node, mongo, and scss) and feel a bit overwhelmed on how to get started on FCM.
I appreciate any feedback you guys can offer.
