# 插件配置
|
||
|
||
[English](config.md) | 中文
|
||
|
||
让你的插件接受用户在 `cordis.yml` 中传入的配置。
|
||
|
||
## 定义 Config 类型
|
||
|
||
在插件中导出一个 `Config` 类型和同名的 Schemastery schema;默认值直接写在 schema 中:
|
||
|
||
```ts
|
||
import type { Context } from 'cordis'
|
||
import Schema from 'schemastery'
|
||
|
||
export const name = 'my-plugin'
|
||
|
||
export interface Config {
|
||
greeting: string
|
||
maxRetries: number
|
||
verbose?: boolean
|
||
}
|
||
|
||
export const Config: Schema<Config> = Schema.object({
|
||
greeting: Schema.string().default('Hello'),
|
||
maxRetries: Schema.number().default(3),
|
||
verbose: Schema.boolean().default(false),
|
||
})
|
||
|
||
export function apply(ctx: Context, config: Config) {
|
||
console.log(config.greeting) // User value or schema default.
|
||
}
|
||
```
|
||
|
||
用户在 `cordis.yml` 中这样使用:
|
||
|
||
```yaml
|
||
- name: './src/my-plugin.ts'
|
||
config:
|
||
greeting: 'Hi there'
|
||
maxRetries: 5
|
||
```
|
||
|
||
插件加载时,Cordis 会通过导出的 schema 校验配置,并填充未提供字段的默认值。不要导出普通对象作为 `Config`,因为它不满足 Cordis 要求的 Standard Schema 接口。
|
||
|
||
## Schema 校验
|
||
|
||
对于需要严格校验的场景,使用 Schemastery 定义 schema:
|
||
|
||
```ts
|
||
import type { Context } from 'cordis'
|
||
import Schema from 'schemastery'
|
||
|
||
export const name = 'validated-plugin'
|
||
|
||
export interface Config {
|
||
apiKey: string
|
||
timeout: number
|
||
mode: 'fast' | 'accurate'
|
||
}
|
||
|
||
export const Config = Schema.object({
|
||
apiKey: Schema.string().required(),
|
||
timeout: Schema.number().default(30000),
|
||
mode: Schema.union(['fast', 'accurate']).default('fast'),
|
||
})
|
||
|
||
export function apply(ctx: Context, config: Config) {
|
||
// config is validated and type-safe.
|
||
}
|
||
```
|
||
|
||
Schema 在插件加载时执行校验。如果配置不合法,插件会加载失败并给出明确错误信息。
|
||
|
||
## 设计原则
|
||
|
||
### 无硬编码可调参数
|
||
|
||
Harness 的约定:**任何两个部署可能想要不同值的东西,都应该是配置字段**。
|
||
|
||
```ts
|
||
// Wrong: hardcoded timeout.
|
||
const TIMEOUT = 30000
|
||
|
||
// Correct: configurable.
|
||
export interface Config {
|
||
timeoutMs: number // Defaults to 30000.
|
||
}
|
||
```
|
||
|
||
检验标准:能否在 `cordis.yml` 中改变这个值,而不需要修改代码?
|
||
|
||
### 配置错误要响亮
|
||
|
||
如果配置引用了未注册的 LLM 提供方路由或其他不存在的资源,应该尽早报错,而不是静默跳过:
|
||
|
||
```ts
|
||
import type { Context } from 'cordis'
|
||
import type {} from '@deepseek-ai/dsh-llm'
|
||
|
||
export interface ModelConfig {
|
||
provider: string
|
||
}
|
||
|
||
export function apply(ctx: Context, config: ModelConfig) {
|
||
if (!ctx.llm.listProviders().some(provider => provider.id === config.provider)) {
|
||
throw new Error(`LLM provider "${config.provider}" is not registered`)
|
||
}
|
||
}
|
||
```
|
||
|
||
## 配合 HMR
|
||
|
||
配置变更会触发插件热替换:修改 `cordis.yml` 中某个插件的 `config`,框架会卸载旧实例、加载新实例。由于注册都是效果(自动清理),这个过程是安全的。

- [插件与生命周期](../framework/) — 深入了解插件的完整生命周期
|

- [服务与依赖](../framework/service.md) — 让你的插件对外提供服务
