Package Management[edit]
Once Hex is installed, you can leverage its functionality to manage your Elixir project's dependencies. Here are some key features available through Hex:
Fetching Packages[edit]
To retrieve a package from Hex, you can use the `mix` command along with the `deps.get` task:
``` $ mix deps.get ```
Hex will download and fetch all the necessary dependencies specified in your project's `mix.exs` file. This ensures that your Elixir project can access the required libraries effortlessly.
Updating Packages[edit]
To update all the dependencies in your project to their latest versions, use the `mix` command with the `deps.update` task:
``` $ mix deps.update --all ```
Hex will check for new versions of the packages and update them accordingly, ensuring that your project remains up to date with the latest features and bug fixes.
Publishing Packages[edit]
If you have developed an Elixir library and want to share it with the community, Hex provides a simple way to publish your package. First, create an account on the Hex website, then run the following command in your library's directory:
``` $ mix hex.publish ```
Hex will guide you through the process of publishing your package and making it available for others to use.
Exploration and Discovery[edit]
Hex not only provides package management capabilities but also serves as a hub for exploring the wealth of available libraries in the Elixir ecosystem. You can search for packages, explore their details, and find relevant information about them. Here are a few ways to uncover new packages:
Hex Website[edit]
