Json Rpc Laravel Package

Product Decisions This Supports

• Build vs. buy for the transport layer. This package is a thin adapter, not a platform: stream_socket_client-based JSON-RPC client aimed at Laravel. The PM decision it informs is whether to standardize on a small, forkable dependency versus building an in-house client or adopting a heavier, community-backed RPC stack. At zero stars and zero dependents, "buy" here really means "vendor and own the risk."
• Feature scope: raw-TCP JSON-RPC endpoints. Relevant when a backend we must integrate (legacy services, node/mining-pool style JSON-RPC endpoints, game or telemetry servers, partner APIs that only expose TCP JSON-RPC) speaks JSON-RPC over a socket rather than HTTP. It lets an MVP ship integration code without standing up an HTTP client layer or a gRPC contract.
• Roadmap: internal service-call standardization. If the roadmap includes a "how do our Laravel services talk to each other" initiative, this package is a candidate for the request/response portion only — it does not address async, connection pooling, retries, or observability, which are exactly the items that typically drive the standard.
• Use cases where it fits the cost envelope: admin tooling and artisan commands hitting internal RPC endpoints; low-volume backend-to-backend calls; queue workers calling a small number of long-lived RPC services; thin integration shims for third-party systems we don't control.
• Risk-acceptance decision. Because adoption signal is effectively nil (0 stars, 0 dependents), adopting it is a decision to accept single-maintainer and supply-chain risk in exchange for a small, readable code surface. A PM should treat this as an explicit, time-boxed risk acceptance rather than a default choice.
• Due-diligence flag. The release date listed (2026-10-23) is in the future relative to normal release cadence; verify tags, changelog, license, and CI before treating the version as stable for planning.

When to Consider This Package

Consider it when:

• One Laravel application needs to talk to a small, known set of JSON-RPC endpoints over raw TCP, at low-to-moderate volume, in a blocking request/response pattern.
• The team is comfortable owning a fork: reading ~a-few-hundred lines of socket code, patching timeouts, reconnect, framing, and error mapping themselves.
• There is no platform mandate (gRPC, GraphQL, OpenAPI/HTTP) and no near-term need for async, connection pooling, or Swoole/ReactPHP-style concurrency.
• The alternative is a bespoke in-house client; a small existing wrapper plus our own tests is cheaper than writing from scratch.
• The integration is internal or non-critical, with a manual fallback (retry, queue replay, or manual reconciliation) if the socket layer misbehaves.
• License and PHP/Laravel version constraints check out during diligence.

Look elsewhere when:

• Throughput or latency matters: raw blocking sockets without pooling, multiplexing, or async support become the bottleneck, and PHP-FPM per-request socket setup adds fixed cost. Prefer Swoole/ReactPHP/AMPHP-based clients or gRPC.
• The endpoints are HTTP-reachable: guzzlehttp/guzzle plus an established JSON-RPC library is better maintained and better supported.
• You need production-grade observability (tracing, structured metrics, per-call hooks), retries with backoff, circuit breaking, or connection health checks — none of which should be assumed from a zero-adoption wrapper.
• You need security review evidence: TLS/mTLS handling, credential storage, input validation, and audit trail need a maintained project with tests and advisories.
• The integration is revenue-critical or contractually SLA-bound; a single-maintainer package with no dependents is not a defensible dependency.
• You need typed contracts and codegen (protobuf/OpenAPI) rather than free-form JSON payloads.
• Documentation in the team's working language is a hard requirement; the description is Chinese, so plan for documentation effort.

How to Pitch It (Stakeholders)

Executive summary. This is a small, low-cost Laravel JSON-RPC client that speaks JSON-RPC over raw TCP sockets. It is a narrow integration utility, not a strategic dependency, and it carries adoption risk: zero community traction and effectively a single maintainer. Recommendation: treat it as a vendored utility with a named internal owner and an exit plan, or skip it in favor of an HTTP-based client if our endpoints allow HTTP. It is worth a time-boxed pilot in one non-critical service, not a fleet-wide standard.

For engineering. Pros: minimal dependency surface, easy to read and fork, direct fit for services that only speak JSON-RPC over a socket, avoids standing up a bespoke client. Cons and required mitigations: wrap it behind our own RpcClient interface so it is swappable; add explicit timeouts, reconnect, and error mapping; add structured logging and metrics at the wrapper level; pin the version and vendor it; add our own integration tests, since the package gives us no assurance of test coverage. Document the wire format and error semantics ourselves. Verify license, PHP/Laravel support matrix, TLS handling, and release provenance before the pilot.

Decision framing. Adopt only if three conditions hold: (1) the endpoints genuinely require raw TCP JSON-RPC, (2) call volume is low enough that blocking sockets are fine, and (3) we accept owning maintenance. Otherwise choose Guzzle-based JSON-RPC over HTTP for maintainability, or gRPC where contracts and performance matter. Set a re-evaluation checkpoint in two quarters against a simple scorecard: incident count, mean patch time on the wrapper, and whether a maintained alternative has emerged.
