在本文中,我就以APIJSON的文档大纲为基础,逐条比较一下Nop平台在作为低代码数据服务引擎使用时与APIJSON的功能差异。 Nop平台作为一个通用的下一代低代码平台,它的发展目标远比APIJSON要宏大得多。Nop平台推行的是所谓面向语言编程范式,即先支持用户快速开发属于自己的DSL领域特定语言,然后再用这个DSL去开发具体业务。
APIJSON的生态相当完整,支持各种后端数据库,有各种语言的客户端,支持自动生成文档,自动进行API测试等一系列外围功能。 Nop平台内置了基于可逆计算原理从零开始设计的下一代GraphQL引擎NopGraphQL和下一代ORM引擎NopORM,它们结合在一起可以很容易的实现类似APIJSON的功能,并且提供更好的可扩展性。在本文中,我就以APIJS...
