+The xx client is designed to be a Go library (and, by extension, a C library).
+
+Support is also present for Go mobile to build Android and iOS libraries. In addition, we bind all exported symbols from
+the bindings package for use on mobile platforms.
+
+This library is also supported by WebAssembly through the [xxdk-wasm](https://git.xx.network/elixxir/xxdk-wasm)
+repository. xxdk-wasm wraps the bindings package in this repository so that they can be used by Javascript when compiled
+for WebAssembly.
### Implementation Notes
-Clients need to perform the same actions *in the same order* as shown in
-`cmd/root.go`. Specifically, certain handlers need to be registered and
-set up before starting network threads. Additionally, you cannot perform certain actions until the network connection reaches a "healthy" state.
+Clients must perform the same actions *in the same order* as shown in `cmd/root.go`. Specifically, certain handlers need
+to be registered and set up before starting network threads. Additionally, you cannot perform certain actions until the
+network connection reaches a "healthy" state.
+
+Refer to Setting Up a cMix Client in the API documentation for specific on how to do this.
+
+See the [xxdk Example repository](https://git.xx.network/elixxir/xxdk-examples/-/tree/master) for various example
+implementations.
+In addition, the [Getting Started](https://xxdk-dev.xx.network/getting-started) guide provides further detail.
+
+You can also visit the [API Quick Reference](https://xxdk-dev.xx.network/quick-reference) for information on the types
+and functions exposed by the Client API.
+
+The main entry point for developing with the client is `xxdk/cmix` (or `bindings/cmix`). We recommend using the
+[documentation in the Go package directory](https://pkg.go.dev/gitlab.com/elixxir/client/xxdk).
+
+If you are developing with the client through the browser and Javascript, refer to the
+[xxdk-wasm](https://git.xx.network/elixxir/xxdk-wasm) repository, which wraps the `bindings/cmix` package. You may also
+want to refer to the [Go documentation](https://pkg.go.dev/gitlab.com/elixxir/xxdk-wasm/wasm).
+
+Looking at the API will, for example, show you there is a `RoundEvents` callback registration function, which lets your
+client see round events.
+
+> ```go
+> func (c *Cmix) GetRoundEvents() interfaces.RoundEvents
+> ```
+> RegisterRoundEventsCb registers a callback for round events.
+
+And then, inside the `RoundEvents` interfaces:
+
+> ```go
+> type RoundEvents interface {
+> // designates a callback to call on the specified event
+> // rid is the id of the round the event occurs on
+> // callback is the callback the event is triggered on
+> // timeout is the amount of time before an error event is returned
+> // valid states are the states which the event should trigger on
+> AddRoundEvent(rid id.Round, callback ds.RoundEventCallback,
+> timeout time.Duration, validStates ...states.Round) *ds.EventCallback
+>
+> // designates a go channel to signal the specified event
+> // rid is the id of the round the event occurs on
+> // eventChan is the channel the event is triggered on
+> // timeout is the amount of time before an error event is returned
+> // valid states are the states which the event should trigger on
+> AddRoundEventChan(rid id.Round, eventChan chan ds.EventReturn,
+> timeout time.Duration, validStates ...states.Round) *ds.EventCallback
+>
+> // Allows the un-registration of a round event before it triggers
+> Remove(rid id.Round, e *ds.EventCallback)
+> }
+> ```
+
+Which, when investigated, yields the following prototype.
+
+> ```go
+> // Callbacks must use this function signature
+> type RoundEventCallback func(ri *pb.RoundInfo, timedOut bool)
+> ```
+
+Showing that you can receive a full `RoundInfo` object for any round event
+received by the client library on the network.
-See [main.go](https://git.xx.network/elixxir/xxdk-examples/-/blob/sample-messaging-app/sample-messaging-app/main.go) for relevant code listings on when and how to perform these actions.

-received by the client library on the network.
+* This command must be run from the directory containing the `.proto` file
+ being compiled.
+* The `-I` flag specifies where to find imports used by the `.proto` file and
+ may need to be modified or removed to suit the .proto file being compiled.\
+ * 💡 **Note:** Note: If you are importing a file from the vendor directory,
+ ensure that you have the correct version by running `go mod vendor`.
+* If there is more than one proto file in the directory, replace `*.proto` with
+ the file’s name.
+* If the `.proto` file does not use gRPC, then the `--go-grpc_out` and
+ `--go-grpc_opt` can be excluded.

+Before following the instructions below, be sure to remove all old versions of
+`protoc`. If your previous protoc-gen-go file is not installed in your Go bin
+directory, it will also need to be removed.
+
+If you have followed this guide previously when installing `protoc` and need to
+update, you can simply follow the instructions below. No uninstallation or
+removal is necessary.
+
+To compile a protocol buffer, you need the protocol buffer compiler `protoc`
+along with two plugins `protoc-gen-go` and `protoc-gen-go-grpc`. Make sure you
+use the correct versions as listed below.
+
+| | Version | Download | Documentation |
+|----------------------|--------:|---------------------------------------------------------------------|-------------------------------------------------------------------------|
+| `protoc` | 3.21.9 | https://github.com/protocolbuffers/protobuf/releases/tag/v3.21.9 | https://developers.google.com/protocol-buffers/docs/gotutorial |
+| `protoc-gen-go` | 1.28.1 | https://github.com/protocolbuffers/protobuf-go/releases/tag/v1.28.1 | https://pkg.go.dev/google.golang.org/protobuf@v1.28.1/cmd/protoc-gen-go |
+| `protoc-gen-go-grpc` | 1.2.0 | https://github.com/grpc/grpc-go/releases/tag/v1.2.0 | https://pkg.go.dev/google.golang.org/grpc/cmd/protoc-gen-go-grpc |
+
+1. Download the correct release of `protoc` from the
+ [release page](https://github.com/protocolbuffers/protobuf/releases) or use
+ the link from the table above to get the download for your OS.
+
+ wget https://github.com/protocolbuffers/protobuf/releases/download/v21.9/protoc-21.9-linux-x86_64.zip
+
+2. Extract the files to a folder, such as `$HOME/.local`.
+
+ unzip protoc-21.9-linux-x86_64.zip -d $HOME/.local
+
+3. Add the selected directory to your environment’s `PATH` variable, make sure
+ to include it in your `.profile` or `.bashrc` file. Also, include your go bin
+ directory (`$GOPATH/bin` or `$GOBIN`) if it is not already included.
+
+ export PATH="$PATH:$HOME/.local/bin:$GOPATH/bin"
+
+ 💡 **Note:** Make sure you update your configuration file once done with
+ source `.profile`.
+
+4. Now check that `protoc` is installed with the correct version by running the
+ following command.
+
+ protoc --version
+
+ Which prints the current version
+
+ libprotoc 3.21.9
-You can verify that all symbols got bound by unzipping
-`bindings-sources.jar` and inspecting the resulting source files.
+5. Next, download `protoc-gen-go` and `protoc-gen-go-grpc` using the version
+ found in the table above.
-Every time you make a change to the client or bindings, you must
-rebuild the client bindings into a .aar or iOS.zip to propagate those
-changes to the app. There's a script that runs gomobile for you in the
-`bindings-integration` repository.
+ go install google.golang.org/protobuf/cmd/protoc-gen-go@v1.28
+ go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@v1.2
-## Roadmap
+6. Check that `protoc-gen-go` is installed with the correct version.
-See the larger network documentation for more, but there are 2 specific
-parts of the roadmap that are intended for the client:
+ protoc-gen-go --version
+ protoc-gen-go v1.28.1
-* Ephemeral IDs - Sending messages to users with temporal/ephemeral recipient
- user identities.
-* User Discovery - A bot that will allow the user to look for others on the
- network.
-* Notifications - An optional notifications system which uses firebase
-* Efficiency improvements - mechanisms for message pickup and network tracking
-* will evolve to allow tradeoffs and options for use
+7. Check that `protoc-gen-go-grpc` is installed with the correct version.
-We are also always looking at simplifying and improving the library interface.

-# Client Bindings
+# xx network Client Bindings
-"bindings" is the client bindings which can be used to generate Android
-and iOS client libraries for apps using gomobile. Gomobile is
-limited to int, string, []byte, interfaces, and only a couple other types, so
-it is necessary to define several interfaces to support passing more complex
-data across the boundary (see `interfaces.go`). The rest of the logic
-is located in `api.go`
+## Allowed Types
+
+> At present, only a subset of Go types are supported.
+>
+> All exported symbols in the package must have types that are supported. Supported types include:
+>
+> - Signed integer and floating point types.
+> - String and boolean types.
+> - Byte slice types. Note that byte slices are passed by reference, and support mutation.
+> - Any function type all of whose parameters and results have supported types. Functions must return either no results,
+ one result, or two results where the type of the second is the built-in 'error' type.
+> - Any interface type, all of whose exported methods have supported function types.
+> - Any struct type, all of whose exported methods have supported function types and all of whose exported fields have
+ supported types. Unexported symbols have no effect on the cross-language interface, and as such are not restricted.
+>
+> The set of supported types will eventually be expanded to cover more Go types, but this is a work in progress.
+>
+> Exceptions and panics are not yet supported. If either pass a language boundary, the program will exit.

+// all the information may be fetched from the NDF using the bindings. These fetch
+// methods are detailed in the parameters section.
+//
+// Params
+// - e2eID - REQUIRED. The tracked e2e object ID. This is returned by [E2e.GetID].
+// - follower - REQUIRED. Network follower function. This will check if the network
+// follower is running.
+// - username - SEMI-REQUIRED. The username the user wants to register with UD.
+// If the user is already registered, this field may be blank. If the user is not
+// already registered, these field must be populated with a username that meets the
+// requirements of the UD service. For example, in the xx network's UD service,
+// the username must not be registered by another user.
+// - registrationValidationSignature - SEMI-REQUIRED. A signature provided by the xx network
+// (i.e. the client registrar). If the user is not already registered, this field is required
+// in order to register with the xx network. This may be nil if the user is already registered
+// or connecting to a third-party UD service unassociated with the xx network.
+// - cert - REQUIRED. The TLS certificate for the UD server this call will connect with.
+// If this is nil, you may not contact the UD server hosted by the xx network.
+// Third-party services may vary.
+// You may use the UD server run by the xx network team by using [E2e.GetUdCertFromNdf].
+// - contactFile - REQUIRED. The data within a marshalled [contact.Contact]. This represents the
+// contact file of the server this call will connect with.
+// If this is nil, you may not contact the UD server hosted by the xx network.
+// Third-party services may vary.
+// You may use the UD server run by the xx network team by using [E2e.GetUdContactFromNdf].

+Channels provide a channels implementation on top of broadcast which is capable

+and eventually admin commands.
+
+on sending, data propagates as follows:
+
+```text
+Send function (Example: SendMessage) - > SendGeneric ->
+Broadcast.BroadcastWithAssembler -> cmix.SendWithAssembler
+```
+
+on receiving messages propagate as follows:
+
+```text

+userListener -> events.triggerEvent ->
+messageTypeHandler (example: Text) ->
+eventModel (example: ReceiveMessage)
+```
+
+on sendingAdmin, data propagates as follows:
+
+```text
+Send function - > SendAdminGeneric ->
+Broadcast.BroadcastAsymmetricWithAssembler -> cmix.SendWithAssembler
+```

+messages which,though trial hashing, are used to determine if a message applies
+to this client.
+
+Services are used for 2 purposes - can be processed by the notification system,
+or can be used to implement custom non fingerprint processing of payloads (i.e.
+key negotiation and broadcast negotiation).
+
+A tag is appended to the message of the format tag = H(H(messageContents),preimage)
+and trial hashing is used to determine if a message adheres to a tag.
+WARNING: If a preimage is known by an adversary, they can determine which
+messages are for the client.
+
+Due to the extra overhead of trial hashing, services are processed after
+fingerprints. If a fingerprint match occurs on the message, triggers will not be
+handled.
+
+Services are address to the session. When starting a new client, all triggers
+must be re-added before StartNetworkFollower is called.

+# Server Initialization
+
+These steps must first be performed in order to begin creating server objects of any variety.
+
+### Make an xxdk.Cmix Object
+
+The xxdk.Cmix object created here will be used for all types of xxdk.Identity and server initialization.
+
+1. Obtain the NDF
+
+```go
+ndfJson, err := xxdk.DownloadAndVerifySignedNdfWithUrl(url, cert)
+```
+
+2. If not done in previous runs, create a new xxdk.Cmix object in storage using ndfJson.
+ `storageDir` and `password` may be customized.
+
+Example:
+
+```go
+err := xxdk.NewCmix(ndfJson, "/clientStorage", []byte("testPassword"), "")
+```
+
+3. LoadCmix in order to obtain the xxdk.Cmix object.
+ `storageDir` and `password` may be customized, but must match the values provided to `NewCmix()`.
+ The result of `xxdk.GetDefaultParams()` may also be freely modified according to your needs.
+
+Example:
+
+```go
+client, err := xxdk.LoadCmix("/clientStorage", []byte("testPassword"), xxdk.GetDefaultParams())
+```
+
+4. Start the network follower. Timeout may be modified as needed.
+
+Example:
+
+```go
+err := client.StartNetworkFollower(10*time.Second)
+```
+
+### Make an xxdk.Identity Object
+
+The xxdk.Identity object created here will be used for all types of server initialization.
+It requires an xxdk.Cmix object.
+
+Example:
+
+```go
+identity, err := xxdk.MakeIdentity(client.GetRng(), client.GetStorage().GetE2EGroup())
+```
+
+# Building Servers
+
+### Creating Connect-backed Servers
+
+`receptionId`: the client ID that will be used for all incoming requests.
+Derived from xxdk.Identity object
+
+`privKey`: the private key belonging to the receptionId.
+Derived from xxdk.Identity object
+
+`rng`: from xxdk.Cmix object
+
+`grp`: from xxdk.Cmix storage object
+
+`net`: from xxdk.Cmix object
+
+`p`: customizable parameters for the server
+Obtained and mutable via `connect.GetDefaultParams()`
+
+Example:
+
+```go
+server, err := connect.NewServer(myIdentity.ID, myIdentity.DHKeyPrivate, client.GetRng(),
+ client.GetStorage().GetE2EGroup(), client.GetCmix(), connect.GetDefaultParams())
+```
+
+### Creating Single-backed Servers
+
+`receptionId`: the client ID that will be used for all incoming requests.
+Derived from xxdk.Identity object
+
+`privKey`: the private key belonging to the receptionId.
+Derived from xxdk.Identity object
+
+`grp`: from xxdk.Cmix storage object
+
+`net`: from xxdk.Cmix object
+
+Example:
+
+```go
+server, err := single.NewServer(myIdentity.ID, myIdentity.DHKeyPrivate,
+ client.GetStorage().GetE2EGroup(), client.GetCmix())
+```
+
+# Adding Server Endpoints
+
+Once you have a `server` object, you can begin adding Endpoints to process incoming client requests.
+See documentation in restlike/types.go for more information.
+
+Example:
+
+```go
+// Build a callback for the new endpoint
+// The callback processes a restlike.Message and returns a restlike.Message response
+cb := func(msg *Message) *Message {
+ // Read the incoming restlike.Message and print its contents
+ // NOTE: You may encode the msg.Contents in any way you like, as long as it matches on both sides.
+ // In this case, we're expecting a simple byte encoding.
+ fmt.Printf("Incoming message: %s", string(msg.Content))
+ // Return a friendly response to the incoming message
+ // NOTE: For responses, Content, Headers, and Error are the only meaningful fields
+ return &restlike.Message{
+ Content: []byte("Hello! Nice to meet you."),
+ Headers: &restlike.Headers{
+ Headers: nil,
+ Version: 0,
+ },
+ Error: nil,
+ }
+}
+// Add an endpoint that accepts 'restlike.Get' requests at the 'results' endpoint
+server.GetEndpoints().Add("results", restlike.Get, cb)
+```
