# Managing dependencies
## Go modules
2020-06-30 22:25:50 +05:30
Dex uses [Go modules][go-modules] to manage its dependencies. Go 1.11 or higher is recommended. While Go 1.12 is expected to finalize the Go modules feature, with Go 1.11 you should [activate the Go modules feature][go-modules-activate] before interacting with Go modules.
Here is one way to activate the Go modules feature with Go 1.11.
```
export GO111MODULE=on # manually active module mode
```
You should become familiar with [module-aware `go get`][module-aware-go-get] as it can be used to add version-pinned dependencies out of band of the typical `go mod tidy -v` workflow.
## Adding dependencies
To add a new dependency to dex or update an existing one:
1. Make changes to dex's source code importing the new dependency.
2. You have at least three options as to how to update `go.mod` to reflect the new dependency:
* Run `go mod tidy -v`. This is a good option if you do not wish to immediately pin to a specific Semantic Version or commit.
* Run, for example, `go get <package-name>@<commit-hash>`. This is a good option when you want to immediately pin to a specific Semantic Version or commit.
* Manually update `go.mod`. If one of the two options above doesn't suit you, do this -- but very carefully.

3. Create a git commit to reflect your code changes.
