{"id":17983,"library":"trippy","title":"Trippy Graph Database for LevelDB","description":"Trippy is an experimental, LevelDB-backed graph database that utilizes a 'triple' data model, consisting of 'subject', 'predicate', and 'object' fields, to represent data relationships. Inspired by the more established `levelgraph` project, Trippy was designed to simplify graph streams over remote protocols and processes, specifically integrating with `multilevel` and `level-sublevel` for this purpose. The package is currently at version 0.0.3, with its last known update around 2014, indicating it is an early-stage, unmaintained project. Its core differentiator was its minimalistic approach to graph data storage on top of the LevelDB ecosystem, focusing on explicit triple structures for interconnected queries.","status":"abandoned","version":"0.0.3","language":"javascript","source_language":"en","source_url":"git://github.com/reqshark/trippy","tags":["javascript","level","graph"],"install":[{"cmd":"npm install trippy","lang":"bash","label":"npm"},{"cmd":"yarn add trippy","lang":"bash","label":"yarn"},{"cmd":"pnpm add trippy","lang":"bash","label":"pnpm"}],"dependencies":[{"reason":"Core LevelDB API wrapper.","package":"levelup","optional":false},{"reason":"Native LevelDB bindings, required by levelup.","package":"leveldown","optional":false},{"reason":"Used for partitioning LevelDB instances, mentioned in 'Why?' section.","package":"level-sublevel","optional":false},{"reason":"Used for simplifying graph streams over remote protocols, mentioned in 'Why?' section.","package":"multilevel","optional":false}],"imports":[{"note":"Package is CommonJS-only and relies on older Node.js `require` syntax.","wrong":"import trippy from 'trippy'","symbol":"trippy","correct":"const trippy = require('trippy');"},{"note":"Core dependency for interacting with LevelDB; also CommonJS.","wrong":"import levelup from 'levelup'","symbol":"levelup","correct":"const levelup = require('levelup');"}],"quickstart":{"code":"const levelup = require('levelup');\nconst trippy = require('trippy');\nconst db = trippy(levelup('data'));\n\nconst triple = {\n  s: 'requestshark',\n  p: 'follows',\n  o: 'badeen'\n};\n\ndb.put(triple, function (err) {\n  if (err) {\n    console.error('Error putting triple:', err);\n    return;\n  }\n  console.log('Triple added successfully.');\n\n  db.get({\n    o: 'badeen'\n  }, function (err, value) {\n    if (err) {\n      console.error('Error getting triple:', err);\n      return;\n    }\n    console.log('Found triples:', value);\n  });\n});","lang":"javascript","description":"This example demonstrates initializing Trippy with a LevelDB store, then adding and querying a simple subject-predicate-object triple."},"warnings":[{"fix":"Migrate to actively maintained graph database solutions or LevelDB wrappers like 'levelgraph' which, while also older, saw more sustained development.","message":"This package is explicitly experimental and has been abandoned since its last release over a decade ago (version 0.0.3, last updated ~2014).
