I am trying to understand the following code taken from a service created in a feathersjs app.
// Initializes the `users` service on path `/users`
const createService = require('feathers-knex');
const createModel = require('../../models/users.model');
const hooks = require('./users.hooks');
const filters = require('./users.filters');
module.exports = function () {
const app = this;
const Model = createModel(app);
const paginate = app.get('paginate');
const options = {
name: 'users',
Model,
paginate
};
// Initialize our service with any options it requires
app.use('/users', createService(options));
// Get our initialized service so that we can register hooks and filters
const service = app.service('users');
service.hooks(hooks);
if (service.filter) {
service.filter(filters);
}
};
This file is then imported as follows:
// many requires..
const feathers = require('feathers');
// more requires
const services = require('./services');
// other requires
const app = feathers();
Can someone explain as to what does the line
const app = this
do in the code that is creating the service?
It assigns the value of this
to a variable (well, a constant) with a name that more clearly describes the value than this does. It is designed to make the code easier for maintainers to understand.
