\r\n\r\n## Getting started\r\n\r\nInstall Spring filter ng\r\n\r\n```\r\nnpm install spring-filter-ng\r\n```\r\n\r\n## Angular Support\r\n\r\n Angular | Spring-filter-ng | Status |\r\n ----------| --------------- | ----------- |\r\n 18 | 7.x | Active |\r\n 17 | 6.x | - |\r\n 16 | 5.x | - |\r\n 15 | 4.x | - |\r\n 14 | 3.x | - |\r\n 12/13 | 1.x+ | - |\r\n\r\n\r\n\r\n## Usage\r\n\r\n```ts\r\nimport {SpringFilter, SpringFilterUtils } from 'spring-filter-ng';\r\n```\r\n\r\n```ts\r\n...\r\n\r\npublic searchByFilter() {\r\n\r\n //initialize filter\r\n const filterBuild = new SpringFilter().build(); \r\n \r\n //Build query\r\n const filter = filterBuild.equals(\"email\",\"example@mail.it\").value;\r\n \r\n //Set parametrs for angular http.\r\n const options = SpringFilterUtils.setOptions(value);\r\n \r\n //Fetch datas.\r\n this.fetchApiService.getStuffsByFilter(options)......\r\n \r\n\r\n}\r\n```\r\n\r\n## Example\r\n\r\n```ts\r\n\r\nConsidering an employee\r\n\r\ninterface Employee {\r\n id: number;\r\n firstName: string;\r\n lastName: string;\r\n birthDate: string;\r\n maritalStatus: string;\r\n salary: number;\r\n manager: Employee;\r\n staff: Employee[];\r\n}\r\n\r\n \r\n1. If you want to know the employees who receive a salary greater than 3000:\r\n\r\n const filter = SpringFilter.new().greaterThen(\"employee.salary\", 3000).value;\r\n \r\n2. If you want to know the employees who have marital status divorced or separated and have \r\n at least two stuff members or are not manager:\r\n\r\n const filter = SpringFilter.new().append(\"maritalStatus\").in(\"divorced\", \"separated\")\r\n .and(SpringFilter.new().greaterThan(springFilter.instance().size(\"staff\"), 2).or(\"manager\").isNotNull()).value;\r\n \r\n\r\n```\r\n\r\n## Utils\r\n\r\nIt is possbile to use utils method from SpringFilterUtils .\r\n\r\n| Name | \r\nDescription | \r\n
