Jungles-data-postgres NPM

Jungles Data Postgresql

API

Setup

var data = require('jungles-data-postgres')({
  user: 'james',
  password: '1234',
  database: 'jungles',
  host: '127.0.0.1'
});

data.setup(); // Creates table called instances

Find

var result = data.find(<query object>);

result.many(function (response) {
  // Always called
  // response: Array (can be empty)
});

result.one(function (response) {
  // called when there is atleast one result
  // { id, name, path, arrange, sort, ..data.. }
});

result.empty(function () { 
  // called when result is empty
});

result.error(function (error) {
  // error
});

Remove

var result = data.remove(<query object>);

result.success(function () { });

Save (create, update)

// Create
var result = data.save({ type: 'product', parent: 0, name: 'snowboard', arrange: '0' });
result.success(function () {});

These fields are required to create. Extra fields get json stringified and added to the data column.

// Update
var result = data.save({ id: 1, name: 'skateboard' });
result.success(function () {});

Because there is an id it knows it's an update.

Tree

var result = data.tree(<query object>); 

result.success(function (tree) { });

Structure

{
  id: 1,
  name: 'snowboard',
  path: '/snowboard',
  type: 'product',
  sort: '/0',
  arrange: 0,
  children: [
    {
      id: 2,
      name: 'tags',
      path: '/snowboard/tags',
      type: 'tags',
      sort: '/0/0',
      arrange: 0,

      children: [
        {
          id: 3,
          name: 'red',
          path: '/snowboard/tags/red',
          type: 'tag',
          sort: '/0/0/0',
          arrange: 0,
        }
      ]
    }
  ]
}

Query object examples

{ id: 5} 
// SELECT * FROM instances where id = 5;

{ path: /.*/ } 
// SELECT * FROM instance WHERE path ~ .*;

{ path: /.*/, id: 5 } 
// SELECT * FROM instances WHERE path ~ .* and id = 5;
