Ideas for improvement

[mostafa]

• Wrap errors with a new package-wide error #50
• Use structured logging everywhere #62
• Add docstring to all functions #60
• Load env-vars for configs #85
• Add command arguments to plugin on load #72
• Pass env-vars to the plugin command on load #76
• Intercept traffic #89
• Investigate gob for passing objects to/from plugins (protobuf is more than enough)
• Write tests for logging/hclog_adapter.go (Add more tests #111)
• Create a plugin SDK gatewayd-plugin-sdk#1
• Add a version subcommand to show versions of GatewayD, plugins, Go and OS info #88
• Add Prometheus metrics #57
• Hook types should be introduced. Currently there are two types: notification and normal hooks. Notification hooks are just to notify the plugin that an event happened, while the normal hooks have different purposes. This should be improved.
• The plugin config object should be read and somehow used. Currently it is just loaded into the PluginImpl.Config and not used. Other config parameters should be investigated as well.
• Write a proposal for the built-in plugins: https://github.com/gatewayd-io/gatewayd-plugin-proposals
• Add tracing and instrumentation #147
• Use enum/constant for hook names in protobuf #190
• Create SBOMs for the source code and the Docker image #218
• Add plugin command for managing plugins and their configs #122
• https://github.com/gatewayd-io/internal-proposals/issues/8
• Config file in other formats and mediums should be investigated, as supported by koanf #276
• Review TODOs in code
• Non-unary RPC calls should be investigated #278
• Investigate Bidirectional RPC between GatewayD and the plugins #279
• Consider implementing all features from go-plugin as seems fit #277
• Investigate usage of sigstore/cosign or the Grafana way for signing plugins #280
