Installation

$ npm install --save @iannisz/database-json

Usage

Quick Tutorial:

const db = require('@iannisz/database-json')

// Create a database called 'myFirstDataBase'
db('myFirstDataBase').create()

// Create a table in 'myFirstDataBase', called table1 with an array of columns
db('myFirstDataBase').table('table1').create(['column1', 'col2', 'name', 'age'])

// Insert values into table
db('myFirstDataBase').table('table1').insert(['data1', 2, 'John Doe', 50])
db('myFirstDataBase').table('table1').insert(['data3', 4, 'Johnny Doe', 25])

// Select all data in table
db('myFirstDataBase').table('table1').select('*')
// Will return:
// [
//   { "column1":  "data1", "col2": 2, "name": "John Doe", "age": 50 },
//   { "column1":  "data3", "col2": 4, "name": "Johnny Doe", "age": 25 }
// ]

The db object:

db(dbName) = {
  create: () => {...},
  drop: () => {...},
  backup: (backupName) => {...},
  table(tableName): {
    create: (columnArray) => {...},
    drop: () => {...},
    insert: (dataArray) => {...},
    select: (columnArray, options) => {...}
  }
}

// Create a database
db(dbName).create()

// Delete a database
db(dbName).drop()

// Backup a database
// Will create a copy of the selected database under a different name
db(dbName).backup(backupName)

// Create a table in a database
db(dbName).table(tableName).create([col1, col2, col3...])

// Delete a table in a database
db(dbName).table(tableName).drop()

// Insert data to a table
db(dbName).table(tableName).insert([data1, data2, data3...])

// Select rows from a table
db(dbName).table(tableName).select(columnArray, options)
// Examples:
  // To select everything:
  db('myFirstDataBase').table('table1').select('*')
  // To select only certain columns
  db('myFirstDataBase').table('table1').select(['name', 'age'])
  // To select with certain options
  db('myFirstDataBase').table('table1').select('*', { 'where': 'age==50' })
  // To select and order
  db('myFirstDataBase').table('table1').select('*', { 'order-by-asc': 'name' })
  // Mixed
  db('myFirstDataBase').table('table1').select(
    ['name', 'age'], { 'where': 'age<51', 'order-by-desc': 'age' }
  )
