Passing data between different angular apps

[tanner wilson]

Hi,

I was wondering if there is any way to easily pass data between to angular apps. Kind of like how Android has Intents and explicit Intents to pass data between activities, and different applications.

Or is there a way that the 2 angular apps can both access the same data model. For instance app 1 updates the data model and changes a variable, Can app 2 view that change in the data model and update as well?

Thanks

Hi Tanner,

Sure, there are lots of way's do do this. Are you looking for a client-side solution, or a server-side one? Are your apps on the same domain? If so, localstorage is your friend, as long as you can keep the the stuff really small. If not, it becomes a bit more complex, and takes a bit more planning. If you want a more specific answer, please give us more details on what you want to do.

Regards

Maybe look into the HTML5 messaging API?

Tanner, when you solve this problem, I'd like to know what you did. I would tackle this from phone-gap via writing a plugin that you can then pass messages to. 

If you can assume that you have access to both the applications, then you could assume that both the apps can be actively monitoring a pipeline that you can pass messages over.

Before you attempt this though, ask yourself, are you suffering from X,Y?

Alternatively, you could create a remote messaging system. Where you send messages to a queue online and when the other application opens, all you have to do is sync to a local data-store from that queue. Then, use embedded-urls to pass tokens to apps that have the rights to those temporary queues. This feels a lot easier.

well in our particular case we have multiple angular apps and what we did was sent the rootscope of one app to a variable and pass that variable back to the previous app that needs to access the data from the first app.

Using localstorage could be a security risk, right? Isn't there any other way that we achieve sharing of data between 2 unique angular applications?

[Sander Elias]

Hi Austin,

If you are on version 9 or later, you can use a shared service. Angular 9 provides a way to share an service between angular 9+ apps on the same page

At the risk of stating the obvious...seems like you want them to talk “to each other” instead of to a common api. What’s wrong with just letting them update When the data changes?
In my defense you didn’t describe your reasons for wanting to do this. 😀

[Austin]

What about data sharing between versions of angular 1(AngularJS) and angular 8 .....and yes domain is the same. So currently I am using localstorage to share data between the two versions but that's not secure

[Austin Paul]

The application I'm working on was setup in AngularJS but now the requirement is that newer add on features have to be developed using latest Angular framework. So certain sets of data needs to be shared across the 2 versions without any api intervention.

One way is you can use the url, if it is hosted that way and then use response
