Common helper utilities and wrappers for code reuse.
When we code projects, we constantly encounter a similar set of functionality and logic. This package's intent is to wrap those commonly recurring functionalities and access points into a reusable helper package, so that we don't have to keep maintaining separate code bases.
This package will continue to be updated with more reusable code as well.
types of helpers
- string helpers
- number helpers
- io helpers
- converter helpers
- db type helpers
- net helpers
- reflection helpers
- regex helpers
- time and date helpers
- uuid helpers
- crypto helpers (aes, gcm, rsa, sha, etc)
- csv parser helpers
- wrappers for aws related services
- service discovery / cloud map wrapper (using aws sdk)
- dynamodb / dax wrapper (using aws sdk)
- kms wrapper (using aws sdk)
- redis wrapper (using go-redis package)
- s3 wrapper (using aws sdk)
- ses wrapper (using aws sdk)
- sns wrapper (using aws sdk)
- wrappers for relational database access
- mysql wrapper (using sqlx package)
- sqlite wrapper (using sqlx package)
- sqlserver wrapper (using sqlx package)
- other wrappers
- for running as systemd service
- for logging and config
- for circuit breaker and rate limit
- etc.
