# Composer NPM bridge
*NPM integration for Composer packages.*
> This package is a fork from https://github.com/eloquent/composer-npm-bridge (thanks to them!)
## Installation
- Available as [Composer] package [oat-sa/composer-npm-bridge].
[composer]: http://getcomposer.org/
[oat-sa/composer-npm-bridge]: https://packagist.org/packages/oat-sa/composer-npm-bridge
## Requirements
- The `npm` executable must be available in PATH.
## Usage
To utilize the *Composer NPM bridge*, simply add `oat-sa/composer-npm-bridge`
to the `require` section of the project's Composer configuration:
composer require oat-sa/composer-npm-bridge
NPM dependencies are specified via a [package.json] configuration file in the
root directory of the Composer package. Source control should be configured to
ignore NPM's `node_modules` directory, similar to Composer's `vendor` directory.
[package.json]: https://npmjs.org/doc/json.html
## How does it work?
The *Composer NPM bridge* is a Composer plugin that automatically installs and
updates [NPM] packages whenever the corresponding Composer command is executed.
To detect compatible packages, the bridge inspects Composer package
configuration information to find packages that directly require the
`oat-sa/composer-npm-bridge` Composer package itself.
In addition to normal operation, `composer install` will [install] NPM
dependencies for all Composer packages using the bridge. This includes the root
package, as well as Composer dependencies.
Similarly, `composer update` will
[install] NPM dependencies for all Composer dependencies using the bridge. It
will also run `npm install` for the NPM dependencies.
NPM dependencies will be installed exactly as if `npm install` were run from the
root directory of the package. This applies even if the package is installed as
a dependency.
[install]: https://npmjs.org/doc/install.html
[npm]: https://npmjs.org/
[update]: https://npmjs.org/doc/update.html
## Configuration
The following configuration can be added to `composer.json` under the
`extra.npm-bridge` section to customize the behavior on a per-package basis.
Values in the root package will not currently impact any dependency packages
that also use *Composer NPM bridge* - each package must define its own options.
Key | Type | Default | Description
----------|-------|---------|---------------------------------------------------
timeout | int | `300` | Specify a custom timeout for the installation (in seconds).
optional | bool | `false` | Skip instead of throwing an exception if `npm` is not found when processing the package.
arguments | array | [] | Add custom NPM arguments
```json5
{
// ...
"extra": {
"npm-bridge": {
"timeout": 9000,
"optional": true,
"arguments": ["--prefix", "someDir"]
},
// ...
}
}
```
*Composer NPM bridge* can be completely disabled by setting the
`COMPOSER_NPM_BRIDGE_DISABLE` environment variable to a non-empty value:
```shell
COMPOSER_NPM_BRIDGE_DISABLE=1 composer install
```
## Caveats
Because NPM dependencies are installed underneath the root directory of the
Composer package, Composer may complain about working copy changes when the
package is installed as a dependency. Source control should be configured to
ignore the `node_modules` directory in order to avoid this.
