@cordisjs/plugin-loader

Runtime plugin loader for Cordis. The loader owns an EntryTree, imports plugin modules by name, applies their config, and keeps the running plugin graph in sync with entry updates.

Usage

import { Context } from 'cordis'
import Loader from '@cordisjs/plugin-loader'

const root = new Context()
await root.plugin(Loader, { baseUrl: import.meta.url })

const id = await root.loader.create({
  name: './plugins/example',
  config: { enabled: true },
})

await root.loader.await()
root.loader.update(id, { config: { enabled: false } })

Entry Options

| Field | Description | | --- | --- | | id | Stable id for resolving, updating, and removing the entry. | | name | Module specifier imported by the loader. | | config | Config passed to the plugin. | | group | Marks the entry as a group whose config is a child entry list. | | disabled | Stops the entry and prevents it from starting. | | inject | Adds required services or intercept config for this entry. |

API

| API | Description | | --- | --- | | loader.create(options, parent?, position?) | Add and start an entry. | | loader.update(id, options, parent?, position?) | Update, move, and restart an entry. | | loader.remove(id) | Stop and delete an entry. | | loader.resolve(id) | Resolve an entry by id, including nested a:b ids. | | loader.resolve(id).moduleNamespace | Raw import result before export normalization; HMR updates it after a successful reload. | | loader.resolveGroup(id) | Resolve the root group or a nested group. | | loader.await() | Wait for pending entry imports and fiber reloads. | | loader.locate(fiber?) | Return the loader entry id that owns a fiber. |

For file-backed trees, use @cordisjs/plugin-include.

Volatile configuration

Entry.update compares raw entry options strictly; when only config changed on an active fiber in an unchanged context, the pure equalExceptVolatile function in config/diff.ts compares the raw configs using Schemastery metadata. It ignores volatile fields at fixed object paths without executing expressions, validators or internal/config hooks. Object nodes use their declared defaults for null or absent values, including objects without volatile fields; equivalent defaults skip updates. Other ordinary values, parent expressions and unknown fields retain raw comparison. Recursive schema backedges use raw comparison. Entry passes the actual plugin schema; a non-Schemastery schema compares raw. Context changes, other option changes and pending fibers use ordinary updates. A volatile-only change retains the raw Fiber config for later activation, then _commitVolatile parses it through the fiber's internal/config hook and schema, commits the new values into the running references when every ordinary effective value still matches, and emits loader/volatile-update to the owning fiber with the changed paths. A changed ordinary effective value uses the ordinary remount with a debug log naming the entry; because strict comparison treats class instances other than URL, Date and RegExp by identity, an ordinary field whose transform builds a fresh instance on every parse always takes that remount. An invalid candidate is logged and leaves the running references unchanged. A throwing loader/volatile-update listener is logged and does not fail the update; the values are already committed. Group/Include retain child dispatch, and programmatic Fiber updates preserve saving and noSave; simplify is called with its schema receiver so saved config contains plain values.
