Machine-produced by `pnpm run rescope-vendor --apply` plus the regeneration it prints: `pnpm install` for the lockfile, `pnpm run gen-third-party-notices`, `verify-translation-pairing --write` for the touched bilingual pairs, `gen-doc-graphs`, and one typert snapshot whose ids embed character offsets. `pnpm run rescope-vendor --check` verifies the result. Renames nine vendored packages (cordis, cosmokit, schemastery and the six @cordisjs plugins) and every reference that resolves them: manifest names and dependency keys, module specifiers including declare-module merges, cordis.yml plugin names, tsconfig paths, every Markdown fence, and `docs/` prose. Directory names, upstream versions, and dependency ranges are unchanged, so vendor/README.md still reads as an upstream snapshot; its manifest table gains an upstream-name column so THIRD_PARTY_NOTICES keeps MIT attribution pointed at each fork's origin. The tutorial tier follows the rename end to end: its yaml fences named plugins the Loader can no longer resolve, its `ts ignore-check` fences disagreed with the compiled fences beside them, and its prose quoted both. The contracts that told readers to keep upstream names — the root convention and the vendoring cookbook's tree comment and manifest invariant — now say to rescope instead. Two rules read `@deepseek-ai/` as "another workspace plugin": the client bundle purity gate now names the vendored libraries a browser bundle inlines, and the files where a bare `cordis` is an agent-preset id keep that product data.

# 5. Configuration
|
|
|
|
English | [中文](05-config.zh.md)
|
|
|
|
Each `cordis.yml` entry can carry a `config` block, and the plugin declares a schema that validates it before `apply` runs. Bad config fails the load with a precise error — the plugin never starts half-configured.
|
|
|
|
## A configurable plugin
|
|
|
|
Create `config-demo.ts` in `tmp/cordis-tutorial`:
|
|
|
|
```ts
|
|
import type { Context } from '@deepseek-ai/cordis'
|
|
import Schema from '@deepseek-ai/schemastery'
|
|
|
|
export const name = 'config-demo'
|
|
|
|
export interface Config {
|
|
greeting: string
|
|
targets: string[]
|
|
}
|
|
|
|
export const Config: Schema<Config> = Schema.object({
|
|
greeting: Schema.string().default('Hello'),
|
|
targets: Schema.array(String).default(['world']),
|
|
})
|
|
|
|
export function apply(ctx: Context, config: Config) {
|
|
for (const target of config.targets) {
|
|
console.log(`${config.greeting}, ${target}!`)
|
|
}
|
|
}
|
|
```
|
|
|
|
The exported `Config` is both a TypeScript interface and a runtime schema with the same name — consumers get the type, Cordis gets the validator. This repo uses [Schemastery](https://github.com/shigma/schemastery) for schemas; Cordis itself accepts any [Standard Schema](https://standardschema.dev/) validator, so a plain object exported as `Config` will not work.
|
|
|
|
Configure it:
|
|
|
|
```yaml
|
|
- name: './config-demo.ts'
|
|
config:
|
|
targets: ['alpha', 'beta']
|
|
```
|
|
|
|
Run:
|
|
|
|
```
|
|
Hello, alpha!
|
|
Hello, beta!
|
|
```
|
|
|
|
`greeting` was omitted, so the schema default filled it in — `apply` always receives complete, validated config.
|
|
|
|
## Fail loud
|
|
|
|
Now feed it something invalid:
|
|
|
|
```yaml
|
|
- name: './config-demo.ts'
|
|
config:
|
|
targets: 'not-an-array'
|
|
```
|
|
|
|
```
|
|
ValidationError: invalid config:
|
|
- $.targets expected array but got not-an-array (at targets)
|
|
```
|
|
|
|
The plugin's fiber goes to FAILED, and this tutorial's launcher exits with status 1 after printing the error. A plugin should also reject schema-valid config that names an unavailable resource or provider as soon as it can resolve that reference.
|
|
|
|
## Computed config values
|
|
|
|
The loader used in this repo supports a `!!js` tag for config values that must be computed at load time:
|
|
|
|
```yaml
|
|
- name: './config-demo.ts'
|
|
config:
|
|
greeting: !!js process.env.DEMO_GREETING ?? 'Hello'
|
|
```
|
|
|
|
`!!js` works **only inside `config`**. Entry metadata (`name`, `id`, `disabled`, `inject`, ...) is static; `disabled: !!js ...` produces a truthy expression object that always disables the entry. See [loader configuration](../cordis-primer.md#loader-configuration).

Next: [Composition and HMR](06-composition-and-hmr.md) — treating `cordis.yml` as the application.
