FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package nexus-ai-tracking
NexusAI Tracking
A standalone, zero-dependency PHP 8.3+ execution store for tracking AI pipeline runs with cost, latency and token metrics. Supports JSONL, SQLite and InMemory backends — usable in any framework or domain.
Why nexus-ai-tracking?
When building AI pipelines (content generation, code assistants, data processors…) you need to answer:
- How much did that run cost?
- Which model is slowest?
- Which prompt version performs best?
- What failed and when?
nexus-ai-tracking gives you append-only, immutable event recording with zero configuration and three backends that suit any environment — from a local script to a production cluster.
Features
- Append-only event store — immutable audit trail, no updates ever
- 3 backends — JSONL files, SQLite, InMemory (testing)
- Thread-safe writes —
flock()file locking on JSONL, transactions on SQLite - Auto-schema — SQLite creates its own schema on first use
- Daily file partitioning — JSONL files split by day, automatic date-range optimization
- Flexible aggregate queries — filter by model, content type, language, date range, event type
- Run projections — grouped
RunSummarywith status, cost, tokens, latency, step count - Extensible — add new backends by implementing one interface
- Zero external dependencies — only
