Editor to share with you how go module uses the local package, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

The use of go module is very simple

Initialize go.mod

Go mod init

Organize dependency packages

Go mod tidy

If you want to cache to the vendor directory

Go mod vendor

The dependency is automatically taken care of after the execution of the command.

However, if we are locally developed packages and do not have a remote repository, how can we solve the problem of local package dependency?

Use replace to replace remote packages with local package services

Fortunately, go module offers another solution, replace. How does this replace work?

Let's take a look at the most basic mod file.

Module GoRoomDemogo 1.12require (github.com/gin-gonic/gin v1.3.0 github.com/gohouse/goroom v0.0.0-20190327052827-9ab674039336 github.com/golang/protobuf v1.3.1 / / indirect github.com/gomodule/redigo v2.0.0+incompatible github.com/mattn/go-sqlite3 v1.10.0 github.com/stretchr/testify v1.3.0 / / indirect golang.org/x/net v0.0.0-20190320064053-1272bf9dcd53 / / indirect)

This is a simple dependency package for the GoRoom framework. If I want to use the native goroom, I just need to use replace

Module GoRoomDemogo 1.12require (github.com/gin-gonic/gin v1.3.0 github.com/gohouse/goroom v0.0.0-20190327052827-9ab674039336 github.com/golang/protobuf v1.3.1 / / indirect github.com/gomodule/redigo v2.0.0+incompatible github.com/mattn/go-sqlite3 v1.10.0 github.com/stretchr/testify v1.3.0 / / indirect golang.org/x/net v0.0.0-20190320064053-1272bf9dcd53 / / indirect) Replace github.com/gohouse/goroom = > / path/to/go/src/github.com/gohouse/goroom where path/to/go/src/github.com/gohouse/goroom is the local package path

In this way, we can happily use the local directory.
