So if you download a different version of the same library then both will be downloaded in a different directory inside $GOPATH/pkg/mod without overriding each other.

All the dependency will be downloaded in the $GOPATH/pkg/mod directory with versioning.

Later in the tutorial we will look at it in detail We already gave a brief introduction of these files in the beginning of this tutorial.

GOLAND CHANGE GO VERSION INSTALL

With go.mod and go.sum files we are able to install precise version of a dependency without breaking anything. With modules it provides two new files that will lie Modules introduced native dependency management within go. With modules this is no longer a requirement. Now let’s see how each of these problems got resolved with the introduction of modules. We already discussed all the problems which existed before the pre-modules era. So if you still using it then better to switch to the latest version After Go Version 1.13 modules was introduced but not finalized. Since there is no versioning the updated package will get downloaded at the same location replacing the older one.

GOLAND CHANGE GO VERSION UPDATE

What if there is an update in the /pborman/uuid package and you want to get that update. Even it doesn’t list down any versioning info. Hence it downloads the latest version present. Notice one thing about the go get command above that no version was specified. It will download the package at location $GOPATH/src//pborman/uuid When we do a go get it will download the required package in the $GOPATH/src directory. Alternate solutions such as dep, glide were available but a native solution was missing. This was a big limitation in terms of that it restricted where you can keep your project.Īlso, one issue before modules was that there was no way to specify a dependency in a project.

Any GO project has to be inside the $GOPATH/src directory.

All the dependency will be downloaded in the $GOPATH/src directory without versioning.

No native dependency management support.

All Go project in $GOPATH/src directory.

These were the problems which existed before the modules era $GOPATH location would have three directories

Go Version 1.13 – Modules was introducedīefore modules go only had packages.

Go Version 1.11 – Modules was introduced but not finalized.

Pre Go version 1.11 – Modules did not exist at all.

Let’s see version wise changes to fully understand what was the limitations earlier and what has changed since modules

GOLAND CHANGE GO VERSION CODE

Also when it is common piece of code and you want to share that code across multiple projects.

However a collection of packages can be called as module when there is a requirement to version them separately. So whatever applied for a package also applies now. The behaviour of packages inside a module is same as earlier. This to make validate that your project’s dependent modules are not changed.

With modules go project doesn’t necessarily have to lie the $GOPATH/src folder.Īlso in addition to go.mod file go also keeps a go.sum file which contains the cryptographic hash of bits of all project’s dependent modules.

It defines both project’s dependencies requirement and also locks them to their correct version Dependency requirements of the module for a successful build.As per module definition, it is a directory containing a collection of nested and related go packages go.mod at its root.
