{"library":"saslmechanisms","title":"SASL Authentication Framework","description":"saslmechanisms is a foundational JavaScript framework designed to facilitate SASL (Simple Authentication and Security Layer) authentication and data security within connection-oriented protocols. Released as version 0.1.1 over a decade ago, it provides a `Factory` pattern for managing and negotiating pluggable SASL mechanisms. The package itself does not include any authentication mechanisms; instead, it serves as an extensible core that requires separate, dedicated packages (e.g., `sasl-plain`) to implement specific SASL methods. Due to its age and lack of updates, it is largely superseded by more modern authentication solutions and is not actively maintained, making its current utility limited outside of legacy systems. The framework's primary differentiator was its modularity, allowing developers to easily extend supported authentication types by plugging in new mechanism implementations.","language":"javascript","status":"abandoned","last_verified":"Sun Apr 19","install":{"commands":["npm install saslmechanisms"],"cli":null},"imports":["const sasl = require('saslmechanisms');\nconst factory = new sasl.Factory();","factory.use(require('sasl-plain'));","const clientSession = factory.createClientSession('PLAIN');"],"auth":{"required":false,"env_vars":[]},"quickstart":{"code":"const sasl = require('saslmechanisms');\n\n// Create a SASL mechanism factory.\nconst factory = new sasl.Factory();\n\n// Register supported SASL mechanisms.
