How to Upgrade the Go Version in a Go Module?

Upgrading the Go Version in a Go Module

Upgrading the Go version in a go mod ensures compatibility with the latest language features and bug fixes.

The Right Approach

Unlike past practices, simply editing the go.mod file to change the version number is the recommended approach. This technique maintains consistency with the module system's dependency management.

The go mod edit Command

For automated upgrades, the go mod edit command provides an explicit option:

go mod edit -go=1.14

This command updates the go.mod file while preserving dependency information.

Manual Editing

Alternatively, you can manually edit the go.mod file. It's a simple text file where the Go version is specified in the following line:

go 1.13

Simply change the version number to 1.14:

go 1.14

Dependency Compatibility

While changing the Go version won't affect compatibility with existing dependencies, it's advisable to consult the dependency release notes to ensure any potential updates align with the new Go version.

Conclusion

Upgrading the Go version in a go mod requires either manual editing or using the go mod edit command. By adhering to the recommended approach and checking dependency compatibility, you can seamlessly upgrade your project to the latest Go version.
