Wire is a code generation tool that automates connecting components using dependency injection. Dependencies between components are represented in Wire as function parameters, encouraging explicit initialization instead of global variables. Because Wire operates without runtime state or reflection, code written to be used with Wire is useful even for hand-written initialization.

For an overview, see the introductory blog post.

Install Wire by running:

go get github.com/google/wire/cmd/wire

and ensuring that $GOPATH/bin is added to your $PATH.
