Example

Here is an example of a Feathers server with a messages in-memory service that supports pagination:

$ npm install @feathersjs/feathers @feathersjs/express @feathersjs/socketio @feathersjs/errors feathers-memory

In app.js:

const feathers = require('@feathersjs/feathers');
const express = require('@feathersjs/express');
const socketio = require('@feathersjs/socketio');
 
const memory = require('feathers-memory');
 
// Create an Express compatible Feathers application instance.
const app = express(feathers());
// Turn on JSON parser for REST services
app.use(express.json());
// Turn on URL-encoded parser for REST services
app.use(express.urlencoded({ extended: true }));
// Enable REST services
app.configure(express.rest());
// Enable REST services
app.configure(socketio());
// Create an in-memory Feathers service with a default page size of 2 items
// and a maximum size of 4
app.use('/messages', memory({
  paginate: {
    default: 2,
    max: 4
  }
}));
// Set up default error handler
app.use(express.errorHandler());
 
// Create a dummy Message
app.service('messages').create({
  text: 'Message created on server'
}).then(message => console.log('Created message', message));
 
// Start the server.
const port = 3030;
 
app.listen(port, () => {
  console.log(`Feathers server listening on port ${port}`)
});

Run the example with node app and go to localhost:3030/messages.
