SQLite

Asynchronous Library for sqlite3

Installation

npm install @surfy/sqlite

Usage

ES6

// Import library
import SQLite from "@surfy/sqlite";

const db = new SQLite('PATH_TO_DB_FILE');
// DB File will be created automatically if not exists
// e.g. /var/data/my_awesome_db.db

CommonJS

// Import library
const SQLite = require('@surfy/sqlite');
const db = await SQLite('PATH_TO_DB_FILE');
// DB File will be created automatically if not exists
// e.g. /var/data/my_awesome_db.db

Methods

.run(query)

await db.run("CREATE TABLE IF NOT EXISTS test_table (id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT, data TEXT);");

await db.run("INSERT OR IGNORE INTO test_table VALUES(NULL, 'Test Record', 'Data content');");

.table(table_name)

Returns Table instance for query processing

let table = await db.table('test_table');

.find(match, options)

Finds matches in a table

let match = {
	id: 1,
	name: {
		$in: ['Test 1', 'Test 2']
	}
};
// ...WHERE id=1 AND name IN ('Test 1', 'Test 2')

let options = {
	fields: ['id', 'name'],
	limit: 2,
	skip: 3
};

/*

Return only id and name fields
Skip first 3 rows
Limit results to 2

*/

let result = await table.find(match, options);

.findOne(match, options)

Finds one row in a table

let match = {
	id: 1
};

let options = {
	fields: ['id', 'name'],
	skip: 3
};

let result = await table.findOne(match, options);

Operators

let match = {
	id: 1,
	name: 'Test 1'
};

// ...WHERE id=1 AND name='Test 1'


match = {
	id: 1,
	name: {
		$in: ['Test 1', 'Test 2']
	}
};

// ...WHERE id=1 AND name IN ('Test 1', 'Test 2')


match = {
	id: 1,
	name: {
		$like: 'Test%'
	}
};

// ...WHERE id=1 AND name LIKE 'Test%'


match = {
	id: 1,
	$or: [
		{
			name: 'Name'
		},
		{
			extra: 'Extra'
		}
	]
};

// ...WHERE id=1 AND ( name='Name' OR extra='Extra' )

.insert(values)

Inserts data into the table

// Single value
let newRow = {
	name: 'Test name',
	data: {
		extraOption: 'Test Data'
	}
};

let insertedIDs = await table.insert(newRow);
// insertedIDs - Array [(int) Inserted_ID]

// Multiple values
let newRows = [
	{
		name: 'Test name 1',
		data: {
			extraOption: 'Test Data 1'
		}
	},
	{
		name: 'Test name 2',
		data: {
			extraOption: 'Test Data 2'
		}
	},
	{
		name: 'Test name 3',
		data: [1, 2, 3]
	}
];

let IDs = await table.insert(newRows);
// Return IDs - Array [(int) Inserted_ID, (int) Inserted_ID, ...]

.insertOne(values)

Inserts a single row into the table

// Single value
let newRow = {
	name: 'Test name'
};

let insertedID = await table.insertOne(newRow);
// insertedID - (int) Inserted_ID

.update(match, update)

let match = {
	id: 1
};

let update = {
	data: 'Updated Data',
	extra: new Date()
};

await test_table.update(match, update);

.each(match, options, callback)

Runs the SQL query with parameters and calls the callback once for each row

let table = await db.table('test_table');

let match = {
	name: 'Test name'
};

let options = {
	fields: ['id', 'name'],
	limit: 2,
	skip: 3
};

table.each(match, options, (err, row) => {
	console.log('Row', row);
});

Date

await db.run("CREATE TABLE IF NOT EXISTS time_table (id INTEGER PRIMARY KEY AUTOINCREMENT, time TEXT);");

let time_table = await db.table('time_table');

let insertedIDs = await time_table.insert([
	{
		id: 1,
		time: 'CURRENT_TIME'
	},
	{
		id: 2,
		time: new Date()
	}
]);

let rows = await time_table.find();

/*

Result
rows = [
	{
		id: 1,
		time: JS Date Object
	},
	{
		id: 2,
		time: JS Date Object
	}
]

*/

Global method

.get(query)

Returns rows or false if error occured

let rows = await db.get("SELECT * FROM test_table WHERE id=1");

.all(query)

Returns rows or false if error occured

let rows = await db.all("SELECT * FROM test_table");

.truncate(table_name)

Truncates table and reset Auto Increment

let result = await db.truncate('test_table');

// @Result True or False

.remove(DB_name)

Removes loaded DB file

let result = await db.removeDB();

/*

@Result
	False if DB file does not exist
	True If successful
*/
