{"id":17566,"library":"database-utils","title":"Database Utils for Node.js (Abandoned)","description":"This `database-utils` package is an **abandoned and unmaintained** Node.js utility library, last updated over a decade ago with version `1.4.1`. It aimed to provide fundamental tools for interacting with databases, including a `SqlBuilder` for constructing SQL queries programmatically and an `ORM` (Object Relational Mapper) for higher-level database interactions. However, its development ceased long ago, and the project's GitHub repository explicitly carries a deprecation notice, advising against its use for anything other than historical research. It does not follow modern best practices, lacks essential features (as indicated by its extensive `TODO` list), and likely has significant compatibility issues with contemporary Node.js versions and database systems. Users seeking database utilities, SQL builders, or ORMs should explore actively maintained alternatives in the Node.js ecosystem, such as `knex`, `sequelize`, `typeorm`, or `prisma`.","status":"abandoned","version":"1.4.1","language":"javascript","source_language":"en","source_url":"https://github.com/unlight/database-utils","tags":["javascript","orm","database","sql","mysql","sqlite","sqlbuilder"],"install":[{"cmd":"npm install database-utils","lang":"bash","label":"npm"},{"cmd":"yarn add database-utils","lang":"bash","label":"yarn"},{"cmd":"pnpm add database-utils","lang":"bash","label":"pnpm"}],"dependencies":[],"imports":[{"note":"The package likely pre-dates widespread ESM adoption and primarily uses CommonJS `require` for its `SqlDriver` class.","wrong":"import { SqlDriver } from 'database-utils';","symbol":"SqlDriver","correct":"const SqlDriver = require('database-utils').SqlDriver;"},{"note":"While 'ORM' is mentioned as a feature, its exact export name and usage pattern are not clearly documented in the available README and might be incomplete or non-existent in practice.
