✨ New Features

Experimental Presence package added (#22499)

@fluid-experimental/presence is now available for investigation. The new package is meant to support presence of collaborators connected to the same container. Use this library to quickly share simple, non-persisted data among all clients or send/receive fire and forget notifications.

API documentation for @fluid-experimental/presence is available at https://fluidframework.com/docs/apis/presence.

There are some limitations; see the README.md of installed package for most relevant notes.

We're just getting started. Please give it a go and share feedback.

🌳 SharedTree DDS changes

Refactor code for emitting events to make it easier to copy into other projects (#22275)

Factored event emitting utilities into their own file, events/emitter.ts. Applications wishing to use SharedTree's eventing library for custom events can copy this file (and its referenced utility function) as a starting point for defining and emitting their own custom events. See createEmitter's documentation for example usage.

Currently there are no published or officially supported versions of these utilities, but they are relatively simple, and can be copied and customized as needed.

A @beta version of nodeChanged which includes the list of properties has been added (#22229)

const factory = new SchemaFactory("example");
class Point2d extends factory.object("Point2d", {
  x: factory.number,
  y: factory.number,
}) {}

const point = new Point2d({ x: 0, y: 0 });

TreeBeta.on(point, "nodeChanged", (data) => {
  const changed: ReadonlySet<"x" | "y"> = data.changedProperties;
  if (changed.has("x")) {
    // ...
  }
});

The payload of the nodeChanged event emitted by SharedTree's TreeBeta includes a changedProperties property that indicates which properties of the node changed.

For object nodes, the list of properties uses the property identifiers defined in the schema, and not the persisted identifiers (or "stored keys") that can be provided through FieldProps when defining a schema. See the documentation for FieldProps for more details about the distinction between "property keys" and "stored keys".

For map nodes, every key that was added, removed, or updated by a change to the tree is included in the list of properties.

For array nodes, the set of properties will always be undefined: there is currently no API to get details about changes to an array.

Object nodes revieve strongly types sets of changed keys, allowing compile time detection of incorrect keys:

TreeBeta.on(point, "nodeChanged", (data) => {
  // @ts-expect-error Strong typing for changed properties of object nodes detects incorrect keys:
  if (data.changedProperties.has("z")) {
    // ...
  }
});

The existing stable "nodeChanged" event's callback now is given a parameter called unstable of type unknown which is used to indicate that additional data can be provided there. This could break existing code using "nodeChanged" in a particularly fragile way.

function f(optional?: number) {
  // ...
}
Tree.on(point, "nodeChanged", f); // Bad

Code like this which is implicitly discarding an optional argument from the function used as the listener will be broken. It can be fixed by using an inline lambda expression:

function f(optional?: number) {
  // ...
}
Tree.on(point, "nodeChanged", () => f()); // Safe

Make SharedTree usable with legacy APIs (#22320)

SharedTree was not previously exported in a way that made it usable with @fluidframework/aqueduct or other lower-level legacy APIs. This fixes that issue by making it consistent with other DDSes: such usages can import { SharedTree } from "@fluidframework/tree/legacy";.

Implicitly constructed object nodes now only consider own properties during validation (#22453)

When determining if some given data is compatible with a particular ObjectNode schema, both inherited and own properties were considered. However, when constructing the node from this data, only own properties were used. This allowed input which provided required values in inherited fields to pass validation. When the node was constructed, it would lack these fields, and end up out of schema. This has been fixed: both validation and node construction now only consider own properties.

This may cause some cases which previously exhibited data corruption to now throw a usage error reporting the data is incompatible. Such cases may need to copy data from the objects with inherited properties into new objects with own properties before constructing nodes from them.

✨ New Features

New isFluidHandle type guard to check if an object is an IFluidHandle (#22029)

The isFluidHandle type guard function is now exported and can be used to detect which objects are IFluidHandles. Since IFluidHandle often needs special handling (for example when serializing since it's not JSON compatible), having a dedicated detection function for it is useful. Doing this detection was possible previously using the tree package's schema system via Tree.is(value, new SchemaFactory("").handle), but can now be done with just isFluidHandle(value).

🌳 SharedTree DDS changes

✨ New! When unambiguous, ArrayNodes can now be constructed from Maps and MapNodes from arrays (#22036)

Since the types for ArrayNodes and MapNodes indicate they can be constructed from iterables, it should work, even if those iterables are themselves arrays or maps. To avoid this being a breaking change, a priority system was introduced. ArrayNodes will only be implicitly constructable from JavaScript Map objects in contexts where no MapNodes are allowed. Similarly MapNodes will only be implicitly constructable from JavaScript Array objects in contexts where no ArrayNodes are allowed.

In practice, the main case in which this is likely to matter is when implicitly constructing a map node. If you provide an array of key value pairs, this now works instead of erroring, as long as no ArrayNode is valid at that location in the tree.

class MyMapNode extends schemaFactory.map("x", schemaFactory.number) {}
class Root extends schemaFactory.object("root", { data: MyMapNode }) {}
// This now works (before it compiled, but error at runtime):
const fromArray = new Root({ data: [["x", 5]] });

Prior versions used to have to do:

new Root({ data: new MyMapNode([["x", 5]]) });

or:

new Root({ data: new Map([["x", 5]]) });

Both of these options still work: strictly more cases are allowed with this change.

✨ New! Record-typed objects can now be used to construct MapNodes (#22042)

You can now construct MapNodes from Record typed objects, similar to how maps are expressed in JSON.

Before this change, an Iterable<string, Child> was required, but now an object like {key1: Child1, key2: Child2} is allowed.

Full example using this new API:

class Schema extends schemaFactory.map("ExampleMap", schemaFactory.number) {}
const fromRecord = new Schema({ x: 5 });

This new feature makes it possible for schemas to construct a tree entirely from JSON-compatible objects using their constructors, as long as they do not require unhydrated nodes to differentiate ambiguous unions, or IFluidHandles (which themselves are not JSON compatible).

Due to limitations of TypeScript and recursive types, recursive maps do not advertise support for this feature in their typing, but it works at runtime.

Implicit TreeNode construction improvements (#21995)

ArrayNodes and MapNodes could always be explicitly constructed (using new) from iterables. The types also allowed using of iterables to implicitly construct array nodes and map nodes, but this did not work at runtime. This has been fixed for all cases except implicitly constructing an ArrayNode form an Iterable that is actually a Map, and implicitly constructing a MapNode from an Iterable that is actually an Array. These cases may be fixed in the future, but require additional work to ensure unions of array nodes and map nodes work correctly.

Additionally MapNodes can now be constructed from Iterator<readonly [string, content]> where previously the inner arrays had to be mutable.
