example using rsocket JS with typescript

Rsocket example

Adapted from: https://github.com/rsocket/rsocket-js/blob/master/packages/rsocket-examples/src/SimpleCli.js

Usage

First run the ExampleCli compiled from rsocket-js examples with babel (see section below)

node build/SimpleCli.js --mode server --protocol ws

Install NPM modules:

npm install

Then build the typescript-based client:

npm run build

Finally run it:

node lib/index.js

Expected result on client side:

x@clr-ac6c3d18a1e44dd9af337de503fff7df~/Code/rsocket-typescript-example $ node lib/index.js

                                                                |___/  |_|                                    |_|
Client connecting to localhost:8080
Connection status: { kind: 'CONNECTED' }
Requesting stream with payload: undefined
requestStream { data: 'Hi!', metadata: null }
onNext(Hello )
onNext(world!)
onComplete()
exit

Expected result on server side:

node build/SimpleCli.js --mode server --protocol ws
Server started on 0.0.0.0:8080
Requesting stream with payload: Hi!
Server got requestStream with payload: data: Hi!,
      metadata: null
onNext(Hello )
onNext(world!)
onComplete()

Building the rsocket-js examples

The rsocket-js examples don’t seem to provide a way to easily compile the modules. To compile the examples yourself you will need to perform the following steps.

First install babel:

npm install -g babel-cli

Now clone the rsocket-js examples:

git clone [e-mail]:rsocket/rsocket-js.git
cd rsocket-js/packages/rsocket-examples/
npm i
npm i yargs --save
echo '{"plugins": ["transform-flow-strip-types","transform-object-rest-spread"], "presets": ["es2015"]}' > .babelrc
npm i babel-plugin-transform-flow-strip-types --save-dev
npm i babel-preset-es2015 --save-dev
npm i babel-plugin-transform-object-rest-spread --save-dev
babel ./src --out-dir=./build

You can now run the example as follows:

node build/SimpleCli.js --mode server --protocol ws

Todo

• Make it work as websocket server like the upstream (non-typescript) SimpleCli.js does.
