Cordis is a powerful and flexible architecture framework designed for building highly modular Node.js applications. It provides a robust dependency injection container, a sophisticated event lifecycle system, and a hot-reloadable plugin engine. The framework allows developers to structure their applications as a collection of independent, reusable services that can seamlessly communicate and depend on one another. It excels at managing complex state and configurations across multiple plugins, ensuring applications remain maintainable as they scale in complexity. It is particularly well-suited for building extensible bots, servers, and command-line tools where a plugin-driven architecture is critical for long-term flexibility.

Ideal for TypeScript and Node.js developers building complex, long-running applications like chat bots or modular servers that require robust plugin architectures and dependency management. Users are expected to have a basic understanding of the relevant underlying technologies.

• Dependency injection: Manages complex service dependencies automatically, ensuring plugins load in the correct order with required resources.
• Sophisticated event system: Provides a rich lifecycle and event bus for seamless, decoupled communication between independent modules.
• Hot-reloadable plugins: Supports dynamically loading, unloading, and reloading plugins at runtime without restarting the entire application.
• Type-safe configuration: Leverages TypeScript to provide rigorous validation and autocomplete for plugin configuration schemas.
• Context isolation: Creates safe, isolated scopes for plugins to prevent memory leaks and unintended interference with global state.

Getting started: npm install cordis

   ## Breaking Changes - loader: `EntryTree.write()` is replaced by `EntryTree.commit(change: EntryChange)`. A subclass receives one `EntryChange` per tree-side mutation, carrying the entry id, its group, the new options, and the previous ones. ## Notable Changes This release improves `@cordisjs/plugin-hmr` in several areas: - A three-stage partial reload makes reloading safer and faster. - `ctx.hmr.watch()` lets a plugin hook its own files into the watcher and decide what a change does. - Config hot-reloading works without `loader.internal`. The reconciliation between the config file and the runtime tree in `@cordisjs/plugin-include` is redesigned: - The loader reports each tree-side mutation as a structured change, and include folds those into a journal. - A read three-way merges the journal against the file. Edits on disjoint entries and keys both survive. On a conflicting key the file wins, and the conflict is logged. - A write applies the journal's deltas onto the last known file content, guarded by a content pre-check and an atomic temp-file replace. Changes left by a failed write stay in the journal and are retried, down to a last flush on dispose. - Change
