Package Exports

sb-config-file

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (sb-config-file) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

sb-config-file

sb-config-file is a Node.js module to help you manage your JSON configuration files without worrying about concurrency issues or double writes. It uses and therefore supports the lodash.get/lodash.set way of accessing properties

API

type Options = {
  prettyPrint: boolean = true,
  atomicWrites: boolean = true,
}

export default class ConfigFile {
  get(dotSeparatedKey: string, defaultValue = null): Promise<any>
  getSync(dotSeparatedKey: string, defaultValue = null): any
  set(dotSeparatedKey: string, value, strict = false): Promise<void>
  setSync(dotSeparatedKey: string, value, strict = false): void
  delete(dotSeparatedKey: string, strict = false): Promise<void>
  deleteSync(dotSeparatedKey: string, strict = false): void

  static get(filePath: string, defaultConfig: Object, options: Options): ConfigFile
}}

Example Usage

const Path = require('path')
const getConfigFile = require('sb-config-file')

getConfigFile(Path.join(__dirname, 'config.json')).then(function(configFile) {
  configFile.set('database.host', 'localhost')
  configFile.set('database.user', 'steelbrain')

  console.log(configFile.get('database.host')) // 'localhost'
  console.log(configFile.get('database.user')) // 'steelbrain'
  console.log(configFile.get('database'))      // { host: 'localhost', user: 'steelbrain' }

  configFile.delete('database.host')
  console.log(configFile.get('database'))      // { user: 'steelbrain' }

  configFile.set('someArray', [1, 2, 3])
  configFile.set('someArray.5', 50)
  console.log(configFile.get('someArray.0')) // 1
  console.log(configFile.get('someArray.1')) // 2
  console.log(configFile.get('someArray.2')) // 3
  console.log(configFile.get('someArray.3')) // undefined
  console.log(configFile.get('someArray.4')) // undefined
  console.log(configFile.get('someArray.5')) // 50
})
