2018年5月4日,Angular6.0.0版正式发布,新版本主要关注底层框架和工具链,目的在于使其变得更小更快。
特性的小改动:
0. 项目特点
该项目有如下特点:
项目升级后也没有使用 @angular/cli,继续采用 fis3 作为编译工具。这一是因为许多历史悠久的代码风格无法通过 tslint 校验,ng build 根本无法执行通过;二是因为项目的部分代码编写和构建与发布流程使用了一些 fis3 的特性,改造成本较大。而且经过比对,@angular/cli 的编译过程并没有比 fis3 好很多。
下面简要介绍一下升级的过程和方法。
1. 更新 package.json 的依赖
将 Angular 依赖库改为 ^6.1.0 版本,并且注意项目依赖的 Angular 组件库的兼容版本更新。如我们的项目依赖有如下变更:
注意:一些组件库的 API 也会有不兼容更新,相关代码逻辑应作改进(可在升级完成后根据文档和错误提示去调试和修改)。
升级后的项目依赖参考:
