Proper transaction support for node-sqlite3.
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 This module is a more modern port of the no longer maintained sqlite3-transactions.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.
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 💩.
yarn install node-sqlite3
yarn install sqlite3-trans
const sqlite3 = require('sqlite3');
const sqlite3Trans = require('sqlite3-trans');
const db = sqlite3Trans.wrap(new sqlite3.Database('lmftfy.db'));
