“The existing documentation is largely OK, most things are explained clearly, and the information is structured logically. Sometimes you may come across pages that were clearly written fast, so the quality of writing may not always be great. There are quickstarts in about seven languages, which is always nice to see, and there’s a diversity of handy how-to guides. Now, for the less positive things. First of all, the API reference seems to be a relatively short page on GitHub and nothing more. Secondly, there are only two tutorials embedded in the docs - and they both focus on building a chat room. More tutorials and more use cases, please! The UI is minimalistic. While sometimes this is a good thing, in this case, it just makes the SignalR documentation (and indeed the product) look and feel like an unimportant or second-hand solution.”

The Breeze documentation is detailed and clear with examples and links to source code. The docs feature a ‘Get Started’ section where you can learn how Breeze works, discover more features, and read the FAQ. The Getting Started guide is well-structured to provide step-by-step guidance on how to set up Breeze and use the APIs, learn how Breeze works, try the Breeze live tutorial, discover features, learn about deploying apps to mobile devices, read the FAQs, and guide you through some of Breeze’s basic capabilities with an emphasis on querying data.

There’s the "Breeze Live Tutorial" which is a quick way to learn basic Breeze interactively – follow the instruction, type in some code, and see the results immediately. The live tutorial page features four (4) panes, consisting of the instruction panel, JavaScript and HTML panels, and Output panel. There’s an extensive API reference and comprehensive individual release notes for each Breeze technology (chat & server).

However, although Breeze is well documented, the developer journey is not straightforward because each Breeze JavaScript library – Angular, Aurelia, Knockout, Backbone, etc. – requires a different setup for its promise and AJAX implementation. API reference documentation is not detailed and seems to only exist on GitHub and be relatively short. The readability and design are mostly good, but they could benefit from a revamp. There’s no demo embedded in the doc.

“The Azure portal is intuitive and pretty easy to use. It provides diverse functionality that allows you to view, create, and manage all the resources you need, such as SingalR instances and connection keys. Among other things, you can also control IAM roles, set up integrations and alerts, and view various logs and metrics, such as the number of connections. More contextual help such as tooltips would be nice, as it’s sometimes unclear what some settings can do."

“The API structure is decently consistent, intuitive, and simple across most SDKs. The Python SDK is a bit obscure, especially when you want to make use of Azure Functions. The entire API reference documentation seems to be available only on GitHub (perhaps not the best platform), and there’s not much API documentation in general. There is a Swagger spec, though, which makes testing the API easier.”

Breeze APIs are consistent across SDKs – same order of operations. The API references are well documented, structured, detailed and extensive – there are examples for some SDKs on GitHub which is a nice thing. However, Breeze APIs are quite complex, so you need to thoroughly study the documentation to learn your way around it.

Azure SignalR Service

Breeze

Realtime features

Pub/Sub messaging

Pub/Sub is a design pattern that lets any number of publishers (producers) push messages to channels (also known as topics). Multiple subscribers (consumers) can subscribe to a channel to consume published messages.

Explore Ably's pub/sub messaging implementation

Limited

You can use Azure SignalR in combination with backplanes such as Redis or Event Grid, which support the pub/sub model. Azure SignalR service is essentially a proxy for client-server communication and does not provide pub/sub capabilities by itself.

Message queues

A message queue is a form of asynchronous service-to-service communication. Messages are stored on a queue until they are processed. Note that each message is only consumed by one subscriber (consumer).

Explore Ably's message queues implementation

Presence

Presence enables you to track the online and offline status of devices and end-users in real time and to store their state. Essential for chat apps and multiplayer games.

Explore Ably's presence implementation

Message history

Message history provides a means to retrieve previously published messages. For this to be possible, message data must be stored (persisted) somewhere.

Explore Ably's message history implementation

Unknown

Connection state recovery (stream resume)

In the case of unreliable network conditions, clients may suddenly disconnect.Connection state recovery ensures that when they reconnect, the data stream resumes exactly where it left off.

Explore Ably' s connection state recovery implementation

Guaranteed message ordering

Ordering ensures that messages are delivered to consumers in the same order that producers publish them.

Explore Ably' s guaranteed message ordering implementation

Limited

There’s EntityManager.saveChanges that you can call multiple times to force Breeze to save a set of entities in the backend database in the same order as they appear.

Exactly-once semantics

Exactly-once is a system-wide data integrity guarantee that ensures each message is delivered to consumers exactly-once.

Explore Ably' s idempotent publishing implementation

Message delta compression

Message delta compression enables you to only send the changes from the previous message to subscribers each time there’s an update, instead of the entire message. Useful for use cases where there is a significant degree of similarity between successive messages.

Explore Ably' s message delta compression implementation

Native push notifications

Native push notifications can be used to deliver messages even when clients are offline. Useful for geolocation updates or news alerts.

Explore Ably's push notifications implementation

Webhooks

Webhooks provide a mechanism to get messages and other types of events (such as clients entering or leaving channels) pushed to your servers over HTTP.

Explore Ably's webhooks implementation

Limited

You can send webhooks to Azure SignalR Service via bindings for Azure Functions. However, SignalR Service can only consume webhooks, but it cannot send webhooks to other systems.

Serverless functions

A serverless function is essentially an isolated, single-purpose piece of code that is only executed when it’ triggered by an event. For example, you can use serverless functions to send a welcome message to clients when they become present on chat channels.

Note that serverless functions are usually fully managed by cloud vendors.

Explore Ably's serverless functions implementation

Limited

Can only trigger Azure Functions. Azure SignalR Service doesn’t have in-built support for other serverless platforms, such as AWS Lambda or Google Cloud Functions.
