Go mod tidy
go mod tidy is a Go command that synchronizes declared module dependencies and checksums with the packages imported by the source code.
Go in Practice, Second Edition
go mod tidy is a Go command that adds missing module requirements and removes unnecessary ones from module metadata.
- How it is used
- Maintains go.mod and the dependency tree after initializing a project, changing versions, or removing dependencies.
- How deep it goes
- Explains the command’s dependency-graph walk and workflow role, but stops short of internal resolution algorithms.
- Examples
- Uses go get -u followed by go mod tidy, with go mod graph for inspecting resulting dependency versions.
- What you can do after
- Operate/configure module metadata and verify dependency changes after updating or removing requirements.

Go in Action, Second Edition
go mod tidy is a Go command that synchronizes module dependencies and their checksums with the packages imported by a project.
- How it is used
- Keeps imported dependencies, go.mod declarations, and go.sum checksums synchronized during project maintenance.
- How deep it goes
- Explains cleanup, addition, and checksum updates, but does not detail the command’s internal resolution algorithm.
- Examples
- Uses an imported package, automatic dependency recording, and the go mod tidy command.
- What you can do after
- Apply it via Go tooling to reconcile a project’s dependencies and checksum records.
