A Knex.js service adapter for FeathersJS
npm install feathers-knex --save
Please refer to the Feathers database adapter documentation for more details or directly at:

Here's a complete example of a Feathers server with a todos
SQLite service. We are using the Knex schema builder
import feathers from 'feathers';
import rest from 'feathers-rest';
import bodyParser from 'body-parser';
import knexService from 'feathers-knex';
const knex = require('knex')({
client: 'sqlite3',
connection: {
filename: './db.sqlite'
}
});
// Clean up our data. This is optional and is here
// because of our integration tests
knex.schema.dropTableIfExists('todos').then(function() {
console.log('Dropped todos table');
// Initialize your table
return knex.schema.createTable('todos', function(table) {
console.log('Creating todos table');
table.increments('id');
table.string('text');
table.boolean('complete');
});
});
// Create a feathers instance.
const app = feathers()
// Enable REST services
.configure(rest())
// Turn on JSON parser for REST services
.use(bodyParser.json())
// Turn on URL-encoded parser for REST services
.use(bodyParser.urlencoded({ extended: true }));
// Create Knex Feathers service with a default page size of 2 items
// and a maximum size of 4
app.use('/todos', knexService({
Model: knex,
name: 'todos',
paginate: {
default: 2,
max: 4
}
}));
app.use(function(error, req, res, next){
res.json(error);
});
// Start the server.
const port = 8080;
app.listen(port, function() {
console.log(`Feathers server listening on port ${port}`);
});
You can run this example by using node server
and going to localhost:8080/todos. You should see an empty array. That's because you don't have any Todos yet but you now have full CRUD for your new todos service!
