Core uniconfig layer: basic ifaces, utils, entry point, plugin API

Install

  npm i @qiwi/uniconfig-core
  yarn add @qiwi/uniconfig-core

Plugin API

uniconfig features may be significantly extended with plugins.

import uniconfig, {rollupPlugin} from '@qiwi/uniconfig-core'
import uniconfigPluginFile from '@qiwi/uniconfig-plugin-api-file'    
import uniconfigPluginYaml from '@qiwi/uniconfig-plugin-yaml'    
import uniconfigPluginDatatree from '@qiwi/uniconfig-plugin-datatree'    

rollupPlugin(uniconfigPluginFile)
rollupPlugin(uniconfigPluginYaml)
rollupPlugin(uniconfigPluginDatatree)
const config = uniconfig('./foobar.yml', {mode: 'sync', pipeline: 'file>yaml>datatree'})    

Each plugin should expose at least two methods to be registered: rollup and rollback.

export interface IContext {
  pipe: IRegistry
}

export interface IPlugin {
  rollback(context: IContext): void,
  rollup(context: IContext): void
}

IPipe with additional name field is also provided as plugin declaration:

  const name = 'test'
  const pipe = {
    handle() {},
    handleSync() {}
  }
  const pipeAsPlugin = {...pipe, name}
  
  rollupPlugin(pipeAsPlugin)
  context.pipe.get(name)  // IPipe
