sqlite3-trans

Proper transaction support for node-sqlite3.

What?

Wraps node-sqlite3 database instances to provide proper transaction support — specifically when utilizing async operations. This module is a more modern port of the no longer maintained sqlite3-transactions.

Differences

• ES6+
• lodash vs underscore
• Don't use deprecated calls
• I'll try to fix bugs. Please report 'em.

Motivation

Considering the following:

db.serialize( () => {
 db.exec('BEGIN;');
 
 // ...
 
 fetchAndInsert(db, () => {
   db.exec('COMMIT;');
 });
});

We just created ourselves a bug! Other database operations in the code may try to do I/O with our DB while in the transaction including an attempt to create another transaction resulting in SQLITE_ERROR: cannot start a transaction within a transaction :poop:.

Install

yarn install node-sqlite3
yarn install sqlite3-trans

Example Usage

const sqlite3       = require('sqlite3');
const sqlite3Trans  = require('sqlite3-trans');

const db = sqlite3Trans.wrap(new sqlite3.Database('lmftfy.db'));
