• Pprof
• Route Groups
• Expose Prometheus Metrics
• Context Management -> Add Keys and Fork context

Issues + Resolutions

1. Implementation for default values is missing, and the MR #2699 for the same seems to be stalled as well as sub par. This may require a custom implementation for now.
   • Added custom implementation for filling in defaults
   • MapDefault
   • MapFormDefault
2. Middleware chaining is a bit awkward → requires mandatory return, but works.
3. Middleware for logging exists, but the middleware seems to be limited to string based outputs using templates and not fully customizable JSON String messages.
   • However, similar support can be added via CustomTags and implementing the JSON log in the same
4. Prometheus Metrics : #166
5. Route name inside middlewares : #2195
