用于开发、UAT 和生产的 Expo App 环境 [英] Expo App environments for Dev, UAT and Production
问题描述
我有一个内置于 Expo 的 React Native 应用程序,它连接到一个 Rest API.剩下的api有3个环境——dev、uat和production,如下(示例).
I have a React Native app built in Expo that connects to a Rest API. There are three environments for the rest api - dev, uat and production as below (example).
dev = https://dev.myapi.com/api
uat = https://uat.myapi.com/api
prod = https://prod.myapi.com/api
根据应用的使用位置,它需要连接到正确的环境.
Depending on where the app is being used it needs to connect to the correct environment.
Running in the Expo Client = Dev API
Running in TestFlight or Internal Testing for the Play Store = UAT API
Running in the App Store or Play Store = Production API
实现这一目标的最简单方法是什么?
What is the simplest way to achieve this?
推荐答案
按照以下步骤操作
安装 expo-constants 包.要安装软件包,请运行以下命令.
Install expo-constants package. To install the package run the below command.
npm i expo-constants
添加 environment.js 文件并粘贴下面的代码.
Add environment.js file and paste below code.
import Constants from 'expo-constants';
import { Platform } from 'react-native';
const localhost = Platform.OS === 'ios' ? 'localhost:8080' : '10.0.2.2:8080';
const ENV = {
dev: {
apiUrl: 'https://dev.myapi.com/api',
amplitudeApiKey: null,
},
staging: {
apiUrl: 'https://uat.myapi.com/api',
amplitudeApiKey: '[Enter your key here]',
// Add other keys you want here
},
prod: {
apiUrl: 'https://prod.myapi.com/api',
amplitudeApiKey: '[Enter your key here]',
// Add other keys you want here
},
};
const getEnvVars = (env = Constants.manifest.releaseChannel) => {
// What is __DEV__ ?
// This variable is set to true when react-native is running in Dev mode.
// __DEV__ is true when run locally, but false when published.
if (__DEV__) {
return ENV.dev;
} else if (env === 'staging') {
return ENV.staging;
} else if (env === 'prod') {
return ENV.prod;
}
};
export default getEnvVars;
- 访问环境变量
// Import getEnvVars() from environment.js
import getEnvVars from '../environment';
const { apiUrl } = getEnvVars();
/******* SESSIONS::LOG IN *******/
// LOG IN
// credentials should be an object containing phone number:
// {
// "phone" : "9876342222"
// }
export const logIn = (credentials, jsonWebToken) =>
fetch(`${apiUrl}/phone`, {
method: 'POST',
headers: {
Authorization: 'Bearer ' + jsonWebToken,
'Content-Type': 'application/json',
},
body: JSON.stringify(credentials),
});
- 要创建构建,请使用以下命令.
Dev - expo build:ios --release-channel dev
分期 - expo build:ios --release-channel 分期
生产 - expo build:ios --release-channel prod
现在 Expo 支持配置文件为 app.config.js 或 app.config.ts,我们可以使用 dotenv.检查这个:https://docs.expo.io/指南/环境变量/#using-a-dotenv-file
Now that Expo supports config file as app.config.js or app.config.ts, we can use the dotenv. Check this: https://docs.expo.io/guides/environment-variables/#using-a-dotenv-file
