Install

Download an executable jar or native binary from Releases.

To get rsc binary working on Windows, you will need to install Visual C++ Redistributable Packages in advance.

Install via Homebrew (Mac / Linux)

Homebrew

You can install native binary for Mac or Linux via Homebrew.

brew install making/tap/rsc

Install via Scoop (Windows)

Scoop

You can install native binary for Windows via Scoop.

scoop bucket add making https://github.com/making/scoop-bucket.git
scoop update
scoop install rsc

Install via Coursier (Mac / Linux / Windows)

Coursier

If you do not already have couriser installed on your machine, install it following steps given here: https://get-coursier.io/docs/cli-installation.

To install the graalvm binary do:

cs install rsc --contrib

To install the jvm binary (executable jar) do:

cs install rscj --contrib

Example usages

rsc --request --route=uppercase --data=Foo --debug tcp://localhost:7001
rsc --stream --route=hello --debug --take=30 ws://localhost:8080/rsocket
rsc --stream --route=searchTweets --data=Trump wss://demo.rsocket.io/rsocket

You can also send data via a file or URL using -l/--load option instead of -d/--data as follows

rsc --request --route=hello --load=./hello.txt --debug tcp://localhost:8080
rsc --request --route=hello --load=/tmp/hello.txt --debug tcp://localhost:8080
rsc --request --route=hello --load=https://example.com --debug tcp://localhost:8080

Enable shell autocompletion

rsc (0.8.0+) provides autocompletion support for Bash, Zsh, Fish and Powershell.

rsc --completion <SHELL>

shows the completion script.

rsc-completion

If you install rsc via Homebrew, the completion script is also installed under /usr/local/Homebrew/completions/.

Below are the procedures to set up autocompletion manually.

Zsh

Add the following to the beginning of your ~/.zshrc

autoload -Uz compinit && compinit

You now need to ensure that the rsc completion script gets sourced in all your shell sessions.

echo 'source <(rsc --completion bash)' >>~/.zshrc

Bash

the completion script depends on bash-completion.

on Mac

the completion script doesn't work with Bash 3.2 which is the default bash version on Mac. It requires Bash 4.1+ and bash-completion v2.

You can install these as follows

brew install bash
brew install bash-completion@2

Make sure bash -v shows 4.1+.

Add the bellow to your ~/.bash_profile

[[ -r "/usr/local/etc/profile.d/bash_completion.sh" ]] && . "/usr/local/etc/profile.d/bash_completion.sh"

You now need to ensure that the rsc completion script gets sourced in all your shell sessions.

echo 'source <(rsc --completion bash)' >>~/.bash_profile

on Linux

You can install bash-completion with apt-get install bash-completion or yum install bash-completion, etc.

Add source /usr/share/bash-completion/bash_completion to your ~/.bashrc.

You now need to ensure that the rsc completion script gets sourced in all your shell sessions.

echo 'source <(rsc --completion bash)' >>~/.bashrc

Fish

TBD (help wanted)

rsc --completion fish

Powershell

rsc --completion powershell | Out-String | Invoke-Expression

Log options

Setup payload

The data in SETUP payload can be specified by --setupData/--sd option and metadata can be specified by --setupMetaData/--smd. Also the MIME type of the setup metadata can be specified by --setupMetadataMimeType/--smmt option.

For example:

rsc --setupData=foo --setupMetadata='{"value":"metadata"}' --setupMetadataMimeType=application/json --route=add --data='{"x":10, "y":20}' tcp://localhost:7001

As of 0.6.0, the following MIME types are supported.

  • application/json (default)
  • text/plain
  • message/x.rsocket.authentication.v0
  • message/x.rsocket.authentication.basic.v0
  • message/x.rsocket.application+json (0.7.1+)

Accordingly, enum name of SetupMetadataMimeType instead can be used with --smmt option

  • APPLICATION_JSON
  • TEXT_PLAIN
  • MESSAGE_RSOCKET_AUTHENTICATION
  • AUTHENTICATION_BASIC

Composite Metadata

rsc always uses Composite Metadata Extension. If multiple metadataMimeTypes are specified, they are automatically composed (the order matters).

$ rsc --metadataMimeType=text/plain --metadata=hello --metadataMimeType=application/json --metadata='{"hello":"world"}' --data='{"x":10, "y":20}' --wiretap --quiet tcp://localhost:7001

If you use --route/-r option, you need to specify to --metadataMimeType/--mmt option for the additional metadata even if the type is application/json which is the default mime type.

For example:

rsc -r functionRouter --mmt application/json -m '{"function":"uppercase"}' -d 'RSocket' tcp://localhost:8080

Backpressure

The onNext output can be delayed with the --delayElements (milli seconds) option. Accordingly, the number of request will be automatically adjusted.

$ rsc --stream --delayElements=100 --log --route=uppercase.stream --data=rsocket tcp://localhost:7001

Tip: Using --limitRate 1 --delayElements 1000 --debug is a convenient way to trace a stream.

Authentication

rsc supports Authentication Extension since 0.6.0.

The demo application is here.

Note that since RSocket Java 1.0.3, username field length is extended.

rsc 0.6.0 uses RSocket Java 1.0.2. To support extended username, rsc 0.7.0 which uses RSocket Java 1.1.0 or above is required.

To send credentials per stream, use --authSimple <username>:<password> option as follows:

rsc tcp://localhost:8888 --authSimple user:password -r hello -d World

For shorter options, --as or -u (like curl!) are also available.

rsc tcp://localhost:8888 -u user:password -r hello -d World

To send credentials in SETUP payload, use --sm simple:<username>:<password> --smmt message/x.rsocket.authentication.v0 as follows.

rsc tcp://localhost:8888 --sm simple:user:password --smmt message/x.rsocket.authentication.v0 -r hello -d World

slightly shorter version

rsc tcp://localhost:8888 --sm simple:user:password --smmt MESSAGE_RSOCKET_AUTHENTICATION -r hello -d World

To send token per stream, use --authBearer <token> option as follows:

rsc tcp://localhost:8888 --authBearer MY_TOKEN -r hello -d World

For shorter option, --ab is also available.

To send credentials in SETUP payload, use --sm token:<token> --smmt message/x.rsocket.authentication.v0 as follows.

rsc tcp://localhost:8888 --sm token:MY_TOKEN --smmt message/x.rsocket.authentication.v0 -r hello -d World

slightly shorter version

rsc tcp://localhost:8888 --sm token:MY_TOKEN --smmt MESSAGE_RSOCKET_AUTHENTICATION -r hello -d World

Basic Authentication

Basic Authentication is not a part of Authentication Extension. It was implemented by Spring Security 5.2 before the spec was standardized.

rsc supports Basic Authentication for the backward compatibility with Spring Security 5.2.

To send credentials per stream, use --authBasic <username>:<password> option as follows:

rsc tcp://localhost:8888 --authBasic user:password -r hello -d World

To send credentials in SETUP payload, use --sm <username>:<password> --smmt message/x.rsocket.authentication.basic.v0 as follows.

rsc tcp://localhost:8888 --sm user:password --smmt message/x.rsocket.authentication.basic.v0 -r hello -d World

slightly shorter version

rsc tcp://localhost:8888 --sm user:password --smmt AUTHENTICATION_BASIC -r hello -d World

Tracing

rsc supports Tracing (Zipkin) Metadata Extension since 0.5.0

The demo application is here.

$ rsc ws://localhost:8080/rsocket -r rr --trace --printB3 --zipkinUrl http://localhost:9411 
Hello World!
b3=5f035ed7dd21129b105564ef64c90731-105564ef64c90731-d

Build

./mvnw clean package -Pnative -DskipTests

A native binary will be created in target/classes/rsc-(osx|linux|windows)-x86_64 depending on your OS.

For linux binary, you can use Docker:

./mvnw spring-boot:build-image  -DskipTests
docker run --rm rsc:<version> --version  

How to run E2E testing

git clone https://github.com/making/rsc-e2e
cd rsc-e2e
export RSC_PATH=...
export RSC_OIDCISSUERURL=https://uaa.run.pivotal.io/oauth/token # you can change this
export RSC_OIDCUSERNAME=...
export RSC_OIDCPASSWORD=...
./mvnw test
