{"library":"marv","type":"library","category":null,"description":"Marv is a programmatic database migration tool designed for Node.js environments, offering a flexible, driver-based approach to managing schema changes. Currently stable at version 6.1.0, it supports a wide range of relational databases including MySQL, PostgreSQL, SQLite, Microsoft SQL Server, and Oracle DB through dedicated pluggable drivers (e.g., `marv-pg-driver`). It distinguishes itself by providing both Promise and Callback-based APIs for integration into various application architectures. Marv's core functionality involves scanning a directory for SQL migration files, validating their sequence, and applying them to the target database. It enforces strict ordering, reporting errors for duplicate levels or out-of-sequence execution, which necessitates careful branching strategies when developing new migrations. Releases appear to follow a semantic versioning approach, with major versions introducing significant changes.","language":"javascript","status":"active","version":"6.1.0","tags":["javascript","marv","database","db","migration","migrate","postgres","postgresql","mysql"],"install":[{"cmd":"npm install marv","imports":["const marv = require('marv/api/promise');","const marv = require('marv/api/callback');","const pgDriver = require('marv-pg-driver');"]},{"cmd":"yarn add marv","imports":[]},{"cmd":"pnpm add marv","imports":[]}],"homepage":"https://guidesmiths.github.io/marv/","github":"https://github.com/guidesmiths/marv","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/marv","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/marv/compatibility"},"provenance":{"verified_status":null,"verified_at":null,"last_verified":"Wed Jun 17","next_check":"Tue Jul 21","install_tag":null}}
