@spree/storefront-api-v2-sdk/src/errors/ExpandedSpreeError.ts

Node module to easily integrate your JavaScript or TypeScript application with Spree API V2. You can create an entirely custom Storefront in JS/TS with this package including one page checkout, Single Page Apps, PWAs and so on

import { AxiosResponse } from 'axios'
import get from 'lodash/get'
import BasicSpreeError from './BasicSpreeError'

export default class ExpandedSpreeError extends BasicSpreeError {
  public errors: any

  constructor(serverResponse: AxiosResponse, errorsSummary: string, errors: any) {
    super(serverResponse, errorsSummary)
    Object.setPrototypeOf(this, ExpandedSpreeError.prototype)
    this.name = 'ExpandedSpreeError'
    this.errors = Object.keys(errors).reduce((acc, field) => {
      const keys = field.split('.')
      let key = keys.shift()
      let node = acc
      while (key) {
        if (!node[key]) {
          if (keys.length === 0) {
            node[key] = errors[field]
          } else {
            node[key] = {}
          }
        }
        node = node[key]
        key = keys.shift()
      }
      return acc
    }, {})
  }

  public getErrors(path: string[]): string[] | null {
    return get(this.errors, path, null)
  }
}
