Feathers Hooks

Important: feathers-hooks is included in Feathers (@feathersjs/feathers) v3 and later and does not have to be loaded and configured separately anymore.

Middleware for Feathers service methods

Documentation

Please refer to the Feathers hooks documentation for more details on:

• The philosophy behind hooks
• How you can use hooks
• How you can chain hooks using Promises
• Params that are available in hooks
• Hooks that are bundled with feathers and feathers plugins

Quick start

feathers-hooks allows to register composable middleware functions when a Feathers service method executes. This makes it easy to decouple things like authorization and pre- or post processing and error handling from your service logic.

To install from npm, run:

$ npm install feathers-hooks --save

Then, to use the plugin in your Feathers app:

const feathers = require('feathers');
const hooks = require('feathers-hooks');

const app = feathers().configure(hooks());

Then, you can register a hook for a service:

// User service
const service = require('feathers-memory');

module.exports = function(){
  const app = this;

  let myHook = function(options) {
    return 
  }

  // Initialize our service
  app.use('/users', service());

  // Get our initialize service to that we can bind hooks
  const userService = app.service('/users');

  // Set up our before hook
  userService.hooks({
    before(hook){
      console.log('My custom before hook ran!');
    }
  });
}
