Angular 环境(environment.ts)设定

给自己看的笔记XD

预设会有两个档案
environment.ts
environment.prod.ts

平时在本机建置时(ng s)读取的会是environment.ts
ng build => environment.ts
ng build --prod => environment.prod.ts

如果要新增环境设定档，去angular.json => configurations 下面新增，比如叫dev

          "configurations": {            "dev": {              "fileReplacements": [              <font color=#800000>酒红色</font>                {                  "replace": "src/environments/environment.ts",                  "with": "src/environments/environment.dev.ts"                }              ],              "optimization": true,              "outputHashing": "all",              "sourceMap": false,              "extractCss": true,              "namedChunks": false,              "extractLicenses": true,              "vendorChunk": false,              "buildOptimizer": true,              "budgets": [                {                  "type": "initial",                  "maximumWarning": "2mb",                  "maximumError": "5mb"                },                {                  "type": "anyComponentStyle",                  "maximumWarning": "6kb",                  "maximumError": "10kb"                }              ]            }          }

然后新增一个档案取名叫做 environment.dev.ts
build的时候下参数 ng build --prod --configuration=dev

就会去吃dev的设定了
