resolveData

resolvers

Source Code | Documentation

Resolves and transforms context.data using a map of resolver functions. Each property in the resolver object receives the current value and can return a transformed value. Runs before next() in the hook pipeline.

  import {  } from 'feathers-utils/resolvers';

Example

import { resolveData, lowercase } from 'feathers-utils/resolvers'

app.service('users').hooks({
  before: {
    create: [resolveData({ email: lowercase() })]
  }
})

Resolver Helpers

Resolver	Description
defaults	Returns a resolver property that sets a default value when the current value is undefined or null. Accepts a static value or a function that receives the hook context.
fromPredicate	Adapts an existing predicate function (like isProvider, isContext) into a resolver condition. The predicate receives the hook context extracted from the resolver options. Only synchronous predicates are supported.
lowercase	Returns a resolver property that converts string values to lowercase. Non-string values are passed through unchanged.
omit	Returns a resolver property that removes the field by returning undefined. When a condition is provided, the field is only omitted if the condition returns true.
setNow	Returns a resolver property that sets the field to the current timestamp (Date.now()). Always overwrites the existing value.
trim	Returns a resolver property that trims whitespace from string values. Non-string values are passed through unchanged.
