In this post, we will explore a variety of Golang packages and tools that can enhance your development experience and improve code quality.
Deprecated Package: PQ Please note that the “github.com/lib/pq” package is no longer maintained. Consider using alternative packages for database connectivity.
SQL Compilers and Helpers:
- SQLC
- Masterminds/Squirrel
- database/sql
- Jackc/pgx
Linters: Linters analyze source code to flag programming errors, bugs, stylistic issues, and suspicious constructs. There are over 50 linters in the Go programming language, but only a few are commonly used:
- go vet
- errcheck
- golint
To use shadow analysis with go vet, you can run:
bashCopy codego install golang.org/x/tools/go/analysis/passes/shadow/cmd/shadow
go vet -vettool=$(which shadow)
Go Tools:
- gofmt: formats Go source code
- goimports: manages import statements
Complexity Checks:
- Gocyclo: calculates cyclomatic complexities of functions in Go source code, helping identify code that needs refactoring
Style Checks:
- golint: prints out style mistakes
- gosimple: simplifies code
- goconst: finds repeated strings that could be replaced by a constant
- misspell: finds commonly misspelled English words in comments
- unconvert: removes unnecessary type conversions
Unused Code Checks:
- varcheck: finds unused global variables and constants
- unused: checks for unused constants, variables, functions, and types
- deadcode: finds unused code
Performance Checks:
- maligned: detects Go structs that could use less memory if their fields were sorted
- gocritic: an opinionated Go source code linter
- prealloc: finds slice declarations that could potentially be preallocated
Bug Finding:
- scopelint: checks for unpinned variables in Go programs
- staticcheck: an enhanced version of go vet that applies numerous static analysis checks
- gosec: inspects source code for security issues
- errcheck: checks for unchecked errors in Go programs
Linter Aggregators:
- gometalinter: an open-source linters runner that aggregates all linters in one and allows running them with a single line of code
- golangci-lint: a linters aggregator that is on average 5 times faster than gometalinter and offers easy integration and minimal false positives
For more information on these tools and packages, refer to the provided links in the original post. Utilizing these resources can help streamline your Golang development process and ensure that your code adheres to best practices.
