It contains components for both server and client side handshake and messaging protocol negotation. Aspects that are left open to interpretation in the specification are also left open in this library. It is up to the implementation to determine how those interpretations are to be dealt with. This library is independent, framework agnostic, and does not deal with any I/O. HTTP upgrade negotiation integration points are handled with PSR-7 interfaces. ### Health Score 69 — FairBetter than 100% of packages Maintenance94 Actively maintained with recent releases Popularity70 Solid adoption and visibility Community42 Growing community involvement Maturity60 Established project with proven stability Bus Factor1 Top contributor holds 60.1% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
