# @FutureOSS/nodejs-adapter
**Pure Node.js Runtime Adapter Service**
## Overview
This plugin is a **service provider only**. It does not contain its own business logic or `pkg` directory with code to run. Instead, it exposes a standardized API for **other plugins** to execute Node.js and npm commands within *their own* `./pkg` directories.
## Architecture
```
┌─────────────────┐ ┌──────────────────────┐ ┌─────────────────┐
│ Consumer │ │ nodejs-adapter │ │ Consumer's │
│ Plugin │─────▶│ (Service Provider) │─────▶│ ./pkg │
│ (e.g., web-app)│ │ │ │ (Node.js proj) │
└─────────────────┘ └──────────────────────┘ └─────────────────┘
```
## Features
- **Context Switching**: Automatically switches working directory to the calling plugin's `./pkg` folder
- **Dependency Isolation**: Ensures npm installs packages into the caller's isolated directory
- **Full npm Support**: Install packages, run scripts, execute files
- **Stateless**: No internal state, pure service provider
## Usage for Plugin Developers
### 1. Declare Dependency
In your plugin's `manifest.json`:
```json
{
"name": "@MyOrg/my-web-plugin",
"dependencies": {
"adapters": ["@FutureOSS/nodejs-adapter"]
}
}
```
### 2. Create Your pkg Directory
```bash
my-web-plugin/
├── manifest.json
├── main.py
└── pkg/ # ← Your Node.js project lives here
├── package.json
├── index.js
└── node_modules/ # ← Dependencies installed here
```
### 3. Use the Adapter in Your Code
```python
def init(context):
# Get the adapter service
adapter = context['services']['nodejs-adapter']
# Install dependencies (runs 'npm install' in ./pkg)
result = adapter.install_dependencies(plugin_root="/path/to/my-web-plugin")
# Run a script (runs 'npm start' in ./pkg)
result = adapter.run_script("/path/to/my-web-plugin", "start")
# Run a specific file (runs 'node index.js' in ./pkg)
result = adapter.run_file("/path/to/my-web-plugin", "index.js")
return {'status': 'active'}
```
## API Reference
### `execute_in_context(plugin_root, command_args, is_npm=False)`
Low-level method to execute any command.
### `install_dependencies(plugin_root, packages=None)`
Install npm packages. If `packages` is None, runs `npm install` (reads from package.json).
### `run_script(plugin_root, script_name, extra_args=None)`
Run an npm script (e.g., `start`, `build`, `test`).
### `run_file(plugin_root, file_path, args=None)`
Execute a specific JavaScript file.
### `init_project(plugin_root, name="plugin-project")`
Initialize a new `package.json` in the plugin's `./pkg` directory.
## Environment Variables
The adapter automatically sets:
- `npm_config_prefix`: Points to the `./pkg` directory for isolated installs
- `NODE_PATH`: Points to `./pkg/node_modules` for module resolution
## Requirements
- Node.js (v14+) installed in the system PATH
- npm installed in the system PATH
## License

"""
Node.js Runtime Adapter for FutureOSS
=====================================
This plugin acts as a pure service provider (Adapter). It does NOT contain its own business logic or pkg.
Instead, it exposes standard interfaces for OTHER plugins to execute Node.js/npm commands
within THEIR own contexts (specifically their ./pkg directories).
Usage by other plugins:
1. Get this adapter from the shared service registry.
2. Call adapter.execute_in_context(plugin_root="./path/to/other-plugin", command="npm start")
3. The adapter will automatically switch CWD to "./path/to/other-plugin/pkg" and run the command.
