Complete Example

The program below runs as-is: copy it into a file and execute go run main.go, or paste it into the Go Playground.

package main

import (
	"fmt"
	"sort"
)

func main() {
	// Before adding a dependency, check whether the standard library already
	// covers the job. Sorting, for example, rarely needs a third-party package.
	nums := []int{3, 1, 2}
	sort.Ints(nums)
	fmt.Println(nums)
}

Expected output:

[1 2 3]

Adding a dependency is a one-liner — the version is recorded in go.mod:

go get github.com/gocolly/colly/v2@latest
go mod tidy

Common Pitfalls

• Check the last commit date. An abandoned library is a future migration cost; prefer actively maintained projects.
• Pinning matters. go get pkg@v1.2.3 records an exact version; go get pkg may bump it.
• go mod tidy before committing. It keeps go.mod/go.sum consistent with the imports in your code.
• Read the license. MIT/Apache-2.0 are permissive; GPL/AGPL impose obligations on distribution.
• Avoid dependency soup. A small wrapper around the standard library is often cheaper than a new module.

Change Log

• 2026-10-14: Added "Before You Start" notes, a complete runnable example with expected output, common pitfalls, and this change log. Completed the truncated Web Scraping table and restored the Consensus Protocols and OCR sections.
