简介

基于事件总线的插件系统，能够快速的让你的应用拥有插件机制，从而变得可扩展

安装

npm install plugineasy --save-dev

使用

const pluginManager = new PluginManager()

pluginManager.register('plugin-a', new APlugin())
pluginManager.register('plugin-b', new BPlugin())

class APlugin implements Plugin {
    apply(pluginManager) {
        this.pluginManager = pluginManager
        pluginManager.on('start', async (data, next) => {
            console.log('[ data ] >', data + '_a')
            await next()
        })
    }
}

class BPlugin implements Plugin {
    public apply(pluginManager) {
        this.pluginManager = pluginManager
        pluginManager.on('start', async (data, next) => {
            console.log('[ data ] >', data + '_b')
            await next()
        })
    }
}

pluginManager.emitSeries('start', 'Hello').catch((error) => {})

// ouput:
// [ data ] > Hello_a
// [ data ] > Hello_b
