咱們須要不一樣的環境下，須要不一樣的參數，好比後端api接口什麼的，使用Angular Cli，能夠很容易的實現這點。在ionic3中，與angular中不同的，還有cordova這一層殼。

假設咱們須要3個環境:dev、uat、prodhtml

web

  • IONIC_ENV: dev、prod，表明2種打包模式(簡單說爲aot與非aot)。
  • NODE_ENV: dev、uat、prod，表明3中不一樣的環境，webapp使用的參數。好比後端server_url不同。cordova而言，好比一些key不同。

區分這兩種概念以後，就能夠理解下面的組合了。node

NODE_ENV與IONIC_ENV的組合:android

  1. dev dev: environments: environment.dev.ts , 非aot方式打包
  2. dev prod: environments: environment.dev.ts , aot方式打包
  3. uat dev: environments: environment.uat.ts , 非aot方式打包
  4. uat prod: environments: environment.uat.ts , 非aot方式打包
  5. prod dev: environments: environment.prod.ts , 非aot方式打包
  6. prod prod: environments: environment.prod.ts , 非aot方式打包

第一步: 在src目錄下新建environments文件夾

增長environment.dev.ts,environment.uat.ts,environment.prod.tswebpack

// environment.dev.ts
export const ENV = {
  "mode": "Dev",
  "database": "data.db",
  "server_url": "https://xxxx.com",
  "cordova":{
    "id":"io.ionic.starter.dev",
    "version":"0.0.1",
    "ios":{
      "CodePushServerUrl": "dev",
      "CodePushDeploymentKey":"1234567890"
    },
    "android":{
      "CodePushServerUrl": "dev",
      "CodePushDeploymentKey":"0987654321"
    }
  }
}

第二步: 修改 tsconfig.json

{
  "compilerOptions": {
    ...
    "baseUrl": "./src",
    "paths": {
      "@env/environment": [ "environments/environment.prod"]
    },
    ...
  },

第三步: 增長 config/webpack.config.js 文件

var chalk = require("chalk");
var fs = require('fs');
var path = require('path');
var useDefaultConfig = require('@ionic/app-scripts/config/webpack.config.js');

var env = process.env.NODE_ENV || 'dev';
var IONIC_ENV = process.env.IONIC_ENV

console.log('NODE_ENV:'+ env);

console.log('IONIC_ENV:'+IONIC_ENV);

if(env === 'dev'){
  if(IONIC_ENV == 'dev'){
    useDefaultConfig.dev.resolve.alias = {
      "@env/environment": path.resolve(environmentPath('dev'))
    };
  };
  if(IONIC_ENV == 'prod'){
    useDefaultConfig.prod.resolve.alias = {
      "@env/environment": path.resolve(environmentPath('dev'))
    };
  };
}

if(env === 'uat'){
  if(IONIC_ENV == 'dev'){
    useDefaultConfig.dev.resolve.alias = {
      "@env/environment": path.resolve(environmentPath('uat'))
    };
  };
  if(IONIC_ENV == 'prod'){
    useDefaultConfig.prod.resolve.alias = {
      "@env/environment": path.resolve(environmentPath('uat'))
    };
  };
}

if(env === 'prod'){
  if(IONIC_ENV == 'dev'){
    useDefaultConfig.dev.resolve.alias = {
      "@env/environment": path.resolve(environmentPath('prod'))
    };
  };
  if(IONIC_ENV == 'prod'){
    useDefaultConfig.prod.resolve.alias = {
      "@env/environment": path.resolve(environmentPath('prod'))
    };
  };
}

function environmentPath(env) {
  var filePath = 'src/environments/environment.' + env + '.ts';
  console.log("use env file:"+filePath);
  if (!fs.existsSync(filePath)) {
    console.log(chalk.red('\n' + filePath + ' does not exist!'));
  } else {
    return filePath;
  }
}

module.exports = function () {
  return useDefaultConfig;
};

第四步: 修改 package.json

增長config配置ios

....
  "config": {
    "ionic_webpack": "./config/webpack.config.js"
  }
  ....

使用方式

import { Component } from '@angular/core';
import {ENV} from '@env/environment'

@Component({
  selector: 'page-page1',
  templateUrl: 'page1.html'
})
export class Page1Page {
  constructor() {
    console.log(ENV.mode);
  }
}

cordova

定義一個config.tpl.xml,使用hooks:before_prepare,在執行cordova prepare以前替換config.xmlgit

第一步: 下載 es6-template-strings

npm install es6-template-strings --save-deves6

第二步: 建立config/hooks/config.tpl.xml

    <engine name="ios" spec="4.5.4" />
    <engine name="android" spec="7.1.0" />
</widget>

第三步: 建立config/hooks/before_prepare.js 

#!/usr/bin/env node
var fs = require('fs');
var path = require('path');
var compile = require('es6-template-strings/compile');
var resolveToString = require('es6-template-strings/resolve-to-string');

var ROOT_DIR = path.resolve(__dirname, '../../')

var env = process.env.NODE_ENV || 'dev';
var envFile = 'src/environments/environment.' + env + '.ts';

var FILES = {
  SRC: "config/hooks/config.tpl.xml",
  DEST: "config.xml"
};

console.log('hooks-start: before_prepare','envFile:'+envFile);

var srcFileFull = path.join(ROOT_DIR, FILES.SRC);
var destFileFull = path.join(ROOT_DIR, FILES.DEST);
var configFileFull = path.join(ROOT_DIR, envFile);

var templateData = fs.readFileSync(srcFileFull, 'utf8');
var configData = fs.readFileSync(configFileFull, 'utf8').toString().split('ENV =')[1];
var config = JSON.parse(configData)['cordova'];

var compiled = compile(templateData);
var content = resolveToString(compiled, config);

fs.writeFileSync(destFileFull, content);

console.log('hooks-end: before_prepare');

第四步，修改現有config.xml

增長<hook src="config/hooks/before_prepare.js" type="before_prepare" />github

<?xml version='1.0' encoding='utf-8'?>
<widget id="io.ionic.starter" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">

    <preference name="SplashScreenDelay" value="3000" />
  +  <hook src="config/hooks/before_prepare.js" type="before_prepare" />
  ....

命令

以uat爲例:web

"serve:uat":  "NODE_ENV=uat ionic build"
  "prepare:uat:prod": "NODE_ENV=uat ionic cordova prepare --prod",
  "build:ios:uat:prod": "NODE_ENV=uat ionic cordova build ios --prod",
  "build:android:uat:prod": "NODE_ENV=uat ionic cordova build android --prod"
