As output, the program provides `json` lines for each given input\n— imagine this as a stream of events arriving at an authorizer consumer.\n\n## Local Setup\n\n#### 1. Requirements\n\n- Java (OpenJDK 15+) ([instruction](https://www.oracle.com/br/java/technologies/javase-downloads.html))\n- Maven (3.6.3+) ([instructions](https://maven.apache.org/install.html))\n- Your favorite IDE (the recommended one is [IntelliJ Community Edition](https://www.jetbrains.com/pt-br/idea/download/)). \n\n#### 2. Build via terminal\nIn this project's root directory, run:\n\n```bash\nmvn clean install\n```\n\n#### 3. Run via terminal\n`AuthorizerApplication` is the project's main file. \nSo, in order to run application, execute:\n\n```bash\nmvn exec:java -Dexec.mainClass=transaction.authorizer.AuthorizerApplication\n```\n\nThe application reads all transaction inputs inside `\"/src/main/java/resources/operations\"`\n, and produces a `output` file in the project's root directory.\n\nIf you want to test application against other transaction inputs, feel free to change \ncontent inside `\"/src/main/java/resources/operations\"`, and re-run application.\n\n#### 4. Run via Intellij\nYou may run the project by executing `AuthorizerApplication` via Intellij as follows:\n\n![Authorizer_Intellij](/docs/authorizer_intellij.gif)\n\n## Application Architecture\n\nLet's talk about the structure or architecture of the application.\nThe project has been separated into the following layers:\n\n1. \u003cb\u003eMain Application\u003c/b\u003e (AuthorizerApplication) starts application, and setups input and output files.\n2. \u003cb\u003eConsumers\u003c/b\u003e receive and handle transaction events.\n3. \u003cb\u003eServices\u003c/b\u003e process transaction events by applying a set of predefined rules, and producing an output for each event.\n4. \u003cb\u003eModels\u003c/b\u003e represent the domain that we're using within the application (e.g., `Account`, and `Transaction`).","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fzeevolution%2Ftransaction-authorizer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fzeevolution%2Ftransaction-authorizer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fzeevolution%2Ftransaction-authorizer/lists"}
