refactor: 客户端目录统一添加 kenaito-conf- 前缀
- go-client → kenaito-conf-go-client - python-client → kenaito-conf-python-client - python-client-demo → kenaito-conf-python-client-demo - nodejs-client → kenaito-conf-nodejs-client - nodejs-client-demo → kenaito-conf-nodejs-client-demo - 更新所有 README 和 package.json 中的路径引用

# Kenaito Config Center Node.js Client
|
||||
|
||||
## 安装
|
||||
|
||||
### 安装到本地仓库(推荐)
|
||||
|
||||
将包注册为全局符号链接,之后任意项目都可以通过 `npm link kenaito-conf` 引用:
|
||||
|
||||
```bash
|
||||
cd kenaito-conf-nodejs-client
|
||||
npm link
|
||||
```
|
||||
|
||||
在你的项目中使用:
|
||||
|
||||
```bash
|
||||
npm link kenaito-conf
|
||||
```
|
||||
|
||||
### 直接引用
|
||||
|
||||
```bash
|
||||
# 在你的项目 package.json 中
|
||||
"dependencies": {
|
||||
"kenaito-conf": "file:../kenaito-conf-nodejs-client"
|
||||
}
|
||||
```
|
||||
|
||||
```bash
|
||||
npm install
|
||||
```
|
||||
|
||||
## 快速开始
|
||||
|
||||
```javascript
|
||||
import { Config, ConfigClient } from 'kenaito-conf';
|
||||
|
||||
const config = new Config({
|
||||
baseUrl: 'http://localhost:8080',
|
||||
appName: 'my-app',
|
||||
env: 'daily',
|
||||
syncInterval: 30,
|
||||
});
|
||||
|
||||
const client = new ConfigClient(config);
|
||||
|
||||
// 监听配置变更
|
||||
client.onChange((changed) => {
|
||||
for (const [k, v] of Object.entries(changed)) {
|
||||
console.log(`config changed: ${k} = ${v}`);
|
||||
}
|
||||
});
|
||||
|
||||
// 启动客户端(拉取配置 + 开启定时同步)
|
||||
await client.start();
|
||||
|
||||
// 获取配置
|
||||
const value = client.get('database.host');
|
||||
const allConfigs = client.getAll();
|
||||
|
||||
// 停止
|
||||
client.stop();
|
||||
```
