Reactive Anagram

Given a string, respond with a set of all anagram permutations.

Eg.

Input: abc

Output: abc, cab, bca, acb, cba, bac

Endpoints:

• Make input string uppercase
• Generate a set of all anagram permutations given a string
• Save permutation in MongoDB

Built using Spring Reactor and Reactive MongoDB NoSQL database

Starting

Using docker-compose

• $ ./gradlew clean build
• $ docker-compose up --build
• This will run 3 things: mongo, anagram and artifactory
• Go to http://localhost:8080/anagram/generate/Xyz
• Check data is inserted
• Run contract test using spring-cloud-contract

$ docker run --rm -e "APPLICATION_BASE_URL=http://192.168.0.8:8080" -e "PUBLISH_ARTIFACTS=true" -e "PROJECT_NAME=anagram" -e "PROJECT_GROUP=anagram" -e "REPO_WITH_BINARIES_URL=http://192.168.0.8:8081/artifactory/libs-release-local" -e "PROJECT_VERSION=0.0.1.RELEASE" -v "/Users/robbiemartinus/dev/rmartinus/reactive-anagram/src/test/resources/contracts/:/contracts:ro" -v "/Users/robbiemartinus/dev/rmartinus/reactive-anagram/src/test/resources/contracts/output:/spring-cloud-contract-output/" springcloud/spring-cloud-contract:1.2.3.RELEASE

• Check artifactory has the stubs: http://localhost:8081/artifactory/libs-release-local
• On the consumer side, you run the stub using spring-cloud-contract-stub-runner

$ docker run --rm -e "STUBRUNNER_IDS=anagram:anagram:0.0.1.RELEASE:stubs:9876" -e "STUBRUNNER_REPOSITORY_ROOT=http://192.168.0.8:8081/artifactory/libs-release-local" -p "8083:8083" -p "9876:9876" springcloud/spring-cloud-contract-stub-runner:"1.2.3.RELEASE"

• Go to http://localhost:9876/anagram/generate/Xyz
• You should get the result as stated in contract yml

Manually

• Start up mongod

  $ sudo mongod

• Start up app

  $ ./gradlew bootRun

• Run AnagramWebClient

• Go to mongo client

  $ mongo

• Check that data is inserted

  > use anagram

  > db.anagram.find()
