ng cli 和 angular 更改版本最佳实践时如何更新应用程序 [英] how to update an app when ng cli and angular change version best practice

问题描述

如何在 ng cli 和 angular 更改版本(如现在使用 ng cli 1.5 和 angular 5 )时更新应用程序?

How to update an app when ng cli and angular change version like now with ng cli 1.5 and angular 5 ?

我的目标是拥有一个现有项目，例如 angular 4 和 ng cli 1.4，更新为 angular 5 和一个由 ng cli 构建的脚手架.(我不知道在这种情况下，但脚手架有时也发生了变化，所以我想要全新的脚手架)

My goal is to have an existing project with for instance angular 4 and ng cli 1.4,updated to angular 5 and the one scaffold built by ng cli. (I don't know in this case but also the scaffold have sometime changed so I want the brand new scaffold)

另一种方法应该是使用 meld.

An alternative should be using meld.

我正在寻找最佳方法/实践，因为现在我正在遵循所有这些步骤.

I'm looking for a best way/practice because right now I'm following all of these steps.

现在我尽可能用 nvm 更新节点版本，例如

By now I update if possible the node version with nvm so for instance

• nvm install v9.0.0

nvm 使用 v9.0.0

npm install -g @angular/cli

ng new myproject

覆盖 src 和 assets 文件夹

overwrite the src and assets folders

更新 package.json

复制.stylelintrc

删除package-lock.json

npm install

正如您所看到的，工作量很大，而且容易出错，所以我想知道是否有更聪明的方法来进行更新.

As you can see a lot of work and also error prone so I'm wondering if there is a smarter way to do the update.

真正的问题是外部库例如对于 OpaqueToken :(

The really problems are the external lib for instance for the OpaqueToken :(
