Trippy Graph Database for LevelDB

0.0.3 verified Thu Apr 23 auth: no javascript abandoned

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.

Common errors

error Error: Cannot find module 'leveldown' (or similar native binding error) ↓

cause Outdated native LevelDB bindings (`leveldown`) are often incompatible with newer Node.js versions or different compilation environments.

fix

This is a fundamental incompatibility issue due to the package's age. It's unlikely to be fixable without significant manual intervention, potentially recompiling native modules for your specific Node.js version and OS. Migration to a current solution is recommended.

error TypeError: db.put is not a function (or similar method missing error) ↓

cause The `trippy` initialization expects a `levelup` instance. If `levelup` fails to initialize or `trippy`'s internal structure changes (which is unlikely given its abandonment, but possible with corrupted installations), methods might be missing.

fix

Ensure levelup('data') successfully returns a valid LevelUP instance and that trippy is correctly wrapping it. Check package installations and Node.js compatibility.

Warnings

breaking This package is explicitly experimental and has been abandoned since its last release over a decade ago (version 0.0.3, last updated ~2014). It is not suitable for production use. ↓

fix Migrate to actively maintained graph database solutions or LevelDB wrappers like 'levelgraph' which, while also older, saw more sustained development.

breaking Dependencies are severely outdated (e.g., `levelup`, `leveldown`, `level-sublevel`, `multilevel`). These older packages may have compatibility issues with modern Node.js versions, especially due to breaking changes in native add-ons or API interfaces. ↓

fix Expect significant refactoring or dependency upgrades if attempting to use in a modern Node.js environment. Many of these older `level` ecosystem packages are no longer actively maintained or have undergone major API changes in their latest versions.

gotcha The package uses a callback-heavy API style typical of older Node.js development. This can lead to 'callback hell' and makes integration with modern async/await patterns cumbersome without manual promisification. ↓

fix Wrap callback-based functions in `new Promise()` to use with `async/await` syntax, or choose a modern library that natively supports Promises.

gotcha Being an unmaintained project, there's no official support for bug fixes, security patches, or feature enhancements. This poses significant stability and security risks for any application incorporating it. ↓

fix Avoid using in any new project. For existing projects, prioritize migration to a actively maintained alternative.

Install

npm install trippy

yarn add trippy

pnpm add trippy

Imports

trippy
wrong
```
import trippy from 'trippy'
```
correct
```
const trippy = require('trippy');
```
Package is CommonJS-only and relies on older Node.js `require` syntax.
levelup
wrong
```
import levelup from 'levelup'
```
correct
```
const levelup = require('levelup');
```
Core dependency for interacting with LevelDB; also CommonJS.

Quickstart

This example demonstrates initializing Trippy with a LevelDB store, then adding and querying a simple subject-predicate-object triple.

const levelup = require('levelup');
const trippy = require('trippy');
const db = trippy(levelup('data'));

const triple = {
  s: 'requestshark',
  p: 'follows',
  o: 'badeen'
};

db.put(triple, function (err) {
  if (err) {
    console.error('Error putting triple:', err);
    return;
  }
  console.log('Triple added successfully.');

  db.get({
    o: 'badeen'
  }, function (err, value) {
    if (err) {
      console.error('Error getting triple:', err);
      return;
    }
    console.log('Found triples:', value);
  });
});
