Angular 6 - 根据环境提供不同的索引文件 [英] Angular 6 - Serving different index files depending on the environment
本文介绍了Angular 6 - 根据环境提供不同的索引文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个本地环境和一个生产环境.在 index.html 中，我根据环境是本地环境还是生产环境添加或删除脚本文件.
I have a local environment and a production environment. Within the index.html i add or remove script files depending on if the environment is local or production.
我想要一个简单的方法来处理这个问题.在 angular.json 中有一个 file_replacement 配置选项.这适用于将 environment.ts 切换为 environment.prod.ts 但它似乎不适用于替换 index.html文件到 index.prod.html.
I want an easy way to handle this. Inside the angular.json there is a file_replacement configuration option. This works for switching out the environment.ts to an environment.prod.ts but it does not seem to work for replacing the index.html file to a index.prod.html.

推荐答案
从 @angular/cli@6.1.0-beta.2 版本开始支持.
更新(2019 年 11 月):
Update (November 2019):
fileReplacements 解决方案可以不工作Angular CLI 8.0.0 不再
The fileReplacements solution does not work with
Angular CLI 8.0.0 anymore
更改 angular.json 以设置您的产品 index.html:
Change angular.json to set your production index.html instead:
"architect":{
"build": {
"options": {
"index": "src/index.html", //non-prod
},
"configurations": {
"production":{
"index": { //prod index replacement
"input": "src/index.prod.html",
"output": "index.html
}
}
}
}
