The client generates random alphabetic strings.\n2. The client streams the randomly generated strings to the vowelcount microservice over a bidirectional channel.\n3. The vowelcount microservice splits the incoming strings into a stream of individual characters which it then sends one by one to the isvowel microservice using request/reply semantics.\n4. The isvowel microservice determines if the character is a vowel and sends back an appropriate boolean response to the vowelcount microservice.\n5. If a vowel was identified by the isvowel microservice, the vowelcount microservice increments its internal vowel counter and streams a message to the client with the latest vowel count.\n\n![diagram](diagram.png)\n\n## Prerequisites\nThis example requires that you have a running Proteus broker.\n\nYou can pull the latest Proteus Broker from DockerHub using the following command:\n\n        $ docker pull netifi/proteus\n\nStart the Proteus Broker by running the following command:\n\n        $ docker run -p 8001:8001 -p 7001:7001 -e BROKER_SERVER_OPTS='-Dnetifi.authentication.0.accessKey=3006839580103245170 -Dnetifi.authentication.0.accessToken=SkOlZxqQcTboZE3fni4OVXVC0e0=' netifi/proteus\n\n## Running the Example\nTODO\n\n## Bugs and Feedback\nFor bugs, questions, and discussions please use the [Github Issues](https://github.com/gregwhitaker/proteus-vowelcount-example/issues).\n\n## License\nCopyright 2018 Greg Whitaker\n\nLicensed under the Apache License, Version 2.0 (the \"License\");\nyou may not use this file except in compliance with the License.\nYou may obtain a copy of the License at\n\n   http://www.apache.org/licenses/LICENSE-2.0\n\nUnless required by applicable law or agreed to in writing, software\ndistributed under the License is distributed on an \"AS IS\" BASIS,\nWITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\nSee the License for the specific language governing permissions and\nlimitations under the License.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgregwhitaker%2Fproteus-vowelcount-example","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgregwhitaker%2Fproteus-vowelcount-example","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgregwhitaker%2Fproteus-vowelcount-example/lists"}
